I dream of becoming a respectable university professor like

Michael J. Sandel after studying abroad. Although it still seems

distant, I go to the university library and study hard every day

to achieve my goal of becoming a well-known professor who

teaches at one of the top universities in the world.

And I want to be smart in reaching my goal. Saving money has

become second nature to me in achieving my dreams. Wouldn’t

it be exciting to see those dreams come true?

Woori Bank supports the dreams of young people as they move forward

in their lives. We offer Woori Student Loan for Studying Abroad, Magic 7

Savings, and My Style Free Savings. We offer them opportunities through

customized products to save at a high interest rate, and also provide

of leading a truly global company one day.

My wife and I opened a coffee shop after I retired from a company

working as a full-time employee for over 30 years. I was afraid of

trying something new in my 50’s, but after becoming a Barista, one

of my happiest moments now is enjoying and serving a cup of fresh

morning coffee. I have my own shop to take care of and I am able to

work flexibly according to my needs. So this was definitely the right

choice. There is a Korean saying that “those who dream, and strive

for something new in life, give more than those who stand still”; that

definitely holds true for me.

Woori Bank offers various products,

such as Woori Franchise Loan, SOHO

Plus Loan and Woori Partners Card, to

support those who are starting up a new

business. We will strive to offer them

products that meet their every need, so

that new entrepreneurs can enjoy a more

prosperous and successful life.

In every spring, I am thrilled to breathe in a fresh

spring scent and bathe in the shining sunlight. As I

walk with my husband, along a boulevard dotted with

trees, I am nostalgic of my life in youth and imbue new

hopes for my life ahead. When the average life span is

100, I think I am still very young. Unlike the past, many

silver generations, like me, seem to positively gear up

for their post-retirement life to start a life anew. I will

continue to make steady investment for my life ahead

to enhance financial stability.

Woori Bank offers diverse products to help customers

who plan to better prepare their post-retirement lives.

These include Happy Life Retirement Pension Bank-book,

Retirement Pensions, and Interest-Prepaid Time Deposit.

It takes a corporate culture that is steeped in the highest standards to foster

genuine teamwork and commitment to the best possible service.

As the first bank to be established in Korea, and having served our customers

for 113 years, we have overcome innumerable challenges along the way. And

we are once again facing uncertain economic times.

to excellence in banking. We aspire to be the undisputed No.1 Bank in Korea,

dear customers,

I would like to extend my sincere thanks to all our customers for giving Woori Bank your

trust and commitment over the past years.

In 2011, Woori Bank achieved net income of KRW 2,069 billion, up KRW 808 billion

from the previous year, and net interest income and non-interest income of KRW 5,200

billion and KRW 1,063 billion respectively, despite the continued economic downturn

at home and abroad and ever-fiercer competition in the market. This reaffirmed our

solid profit structure and business capabilities. Moreover, our BIS capital adequacy ratio

reached 13.78% and the ROA and ROE profitability indicators stood at 0.59% and 7.93%

respectively, levels which confirm our presence as a leading domestic bank.

Meanwhile, our constant efforts to clean up our balance sheet significantly improved the

Bank’s Non Performing Loan(NPL) ratio, to 1.65% as of year-end 2011, down from 3.34%

as of year-end 2010. We will continue to effectively manage asset soundness in 2012.

The financial environment in 2012 will not be easy. As the financial crisis in Europe

and the wider global economic downturn continue, delays in the domestic economic

recovery and possible household defaults put greater emphasis on risk management.

In particular, because only four major commercial banks dominate the banking sector,

competition is expected to grow fiercer.

Supported by the trust of our customers, we are the representative traditional

Korean bank with the longest history for over 113 years. By sharing our hearts

harmoniously, we promise we will continue to fulfill our greater financial

duties in enriching the nation and the national economy, as well as our social

responsibilities in supporting the society in need.

No.1We will make sure that 2012 will be a year when uncertainties and crises become

opportunities by fostering a sense of unity among all 15,000 staff, and by implementing

fundamentally strong and profit-oriented management.

We will undertake preemptive risk management by preparing ourselves against economic

uncertainties and greater volatility, diversify our foreign currency financing structure to

ensure stable liquidity management, and do our utmost to manage our loan-deposit ratio.

We are committed to expanding our network at home and abroad, exploring new market

and new businesses opportunities. Meanwhile, net interest margin(NIM) will be maintained

at a high level, profit structure will be stabilized by raising non-interest income(such as fee

revenues), and profit oriented growth will continue by focusing on prominent customers/

assets.

Our Bank will return the love that customers have given to us to the society as a whole.

We will also expand our support in helping the temporarily troubled or to–be reorganized

SMEs. Furthermore, the Bank will act as a microcredit lender in cooperation with

Woori Miso Financial Foundation, and will help the underprivileged through a strong

commitment to social contribution activities.

We promise to fulfill our role and responsibilities as a bank that enriches the nation and

the national economy. We have shared growth for 113 years, and this would not have

been possible without the love and support of our customers.

Woori Bank has set itself a medium to long-term goal of becoming not only

the No.1 bank in Korea, but also amongst the top 10 in Asia.

CorporateGovernance

Composition of the Board of direCtors

As of the end of March 2012, Woori Bank’s Board of Directors consists of 11 execu-tive directors: one non-standing director, three standing directors and seven outside directors, appointed to increase the relevant expertise and independence of the Board. The seven outside directors are selected based on their experience in the fields of finance, management, law, accounting and public relations; many are also well-known public figures. They support and monitor the Bank’s strategic decision-making and

overall business affairs.

major aCtivities for 2011

The Board held 17 meetings in 2011 to dis-cuss a total of 58 pending issues and 63 briefings, and the overall attendance rate of outside directors was 92%.

At the request of the outside directors, an outside director meeting was held one week

prior to each full Board meeting, to ensure sufficient discussion and in-depth review of pending issues. Directors from different fields promoted effective bank management and maximized shareholders value by as-similating information from activities both inside& outside the Bank, and then giving onsite oriented advice based on these activi-ties & their expertise knowledge.

At each quarterly Board meeting, the quar-terly management records were agreed upon, and general discussions took place, as well as discussions on specific matters. The agenda of different meetings included: reporting on the submission of plans for the implementation of the Memorandum of Un-derstanding (MOU) signed with the Financial Supervisory Service (FSS); results and de-tails of the implementation of the MOU with Korea Deposit Insurance Corporation(KDIC); plans to issue foreign currency-denominated bonds; comprehensive briefings on ma-jor loans; briefings on NPLs; review of the implementation of the Board of Directors’ or-

ders, and briefings on the results of reviews; and, briefings on the activities of the various committees under the Board of Directors. Of particular note, plans were made to en-hance sector-specific expertise and com-petitiveness within the Group. Specifically, in January 2011, a provisional agreement was reached to launch the ‘Woori Fund Service’, a subsidiary which will independently under-take various important functions, including the analysis of fund management perfor-mance, verification of fund-based prices, support for development of fund products, and accounting tasks for funds. In addi-tion, in September 2011, it was provisionally agreed to separate the card business that was previously dealt with internally by the Bank. At the December meeting, the Board also confirmed its draft management plan, following in-depth discussions on many is-sues facing the Bank amid continuing mar-ket changes.

It enables us to take responsibility for our business actions, find new areas of

risk management organization

Woori Bank’s risk management consists of

three independent bodies, each providing

unique insights and checks on the Bank’s

risk environment.

1. The top decision maker is the Board

Risk Management Commit tee, which

meets at least quarterly to deliberate on

risk management strategies & policies, and

to set acceptable risk levels & limits.

2. The Executive Risk Management Com-

mittee holds monthly meetings to review

and revise business plans and department-

level strategies, to ensure continuous

adjustments in response to corporate risk

management strategies and policies. The

Executive Committee also reviews, adjusts

and controls matters in relation to fund

management, as well as risk-specific man-

agement measures.

3. The Risk Management Unit is an inde-

pendent organization which consists of the

Risk Management Department, in charge

of the overall existing risk management is-

sues, and the Loan Review Department,

which takes responsibility for the day-to-

day oversight of Woori Bank’s risk man-

agement operations.

2011 review

Credit risk management

In 2011, Woori Bank operated, managed and

verified new evaluation models (corporate

and retail) approved under the new BIS Inter-

nal Ratings Act, obtaining timely and relevant

reviews of their distinctiveness, predictability

and stability.

Using these models, bankruptcy rates for

each corporate rating and retail pool were es-

timated and verified by the Bank depending

on the time elapsed from approval. The Bank

ensures on a yearly basis that it maintains

distinctive models for separate corporate/

retail evaluation, and always double-checks

their stability and effectiveness in operation.

risk management “Risks Management is the key to

maintaining Profits”: Woori Bank

minimizes losses by identifying

risk quickly and accurately through

best-practice risk management

programs, building a bank that is

robust and reliable.

market risk management

Woori Bank uses the Standard Approach

and the Internal Model to calculate capital

adequacy with respect to modeled market

risk events. The Standard Approach ap-

plies to specific risks provided under Finan-

cial Supervisory Service (FSS) guidelines,

while the Internal Model quantifies general

market risks at the 99% confidence level

using variance-covariance (delta-gamma)

techniques assuming a 10-day holding

period. Potential losses under extreme

situations(such as IMF) are measured us-

ing stress tests to prepare for any critical

events that might surface, and Internal

Model is validated by comparing Profit &

Loss vs VaR using a daily basis back test-

ing method.

operational risk management

For the second time, we successfully com-

pleted the FSS approval and review pro-

cess for our application regarding approval

of the High-level Internal Ratings-based

approach, and acquired final approval in

June 2009. Since then, we have applied it

to our BIS ratio calculation, while also con-

tinuing to improve management systems,

control structures and measurement sys-

tems for the maintenance and upgrading of

risk management.

To this end, we apply the ORM Index in

the Bank-wide performance management

index. We conduct OR coaching for units

struggling to meet the ORM Index, to help

them to reduce OR.

In response to changes in financial state-

ments and the adoption of IFRS, we have

opened a new account and encouraged

improvement of OR measurement systems.

plans for 2012

Credit risk management

In 2012, systems upgrades for credit risks

will unfold in multiple directions. The Bank

will use the early warning systems from the

scoring method developed in 2010, and

expand its usage so that it can be used in

credit approvals.

Corporate credit rating model(MEs/SEs) and retail(household, SOHO, credit cards) credit scoring model developed based on the 2005 ~ 2007 data. These models however will be enhanced within the first half of 2012 by utilizing recent data after 2008.

interest and liquidity risk management

We plan to complete the Phase 1 IT system

within June 2012 to calculate the Bank’s

l iquidity management ratios (LCR and

NSFR) in accordance with Basel III require-

ments. We will also regularly review the

interest rate and liquidity risk management

models by computerizing the back-test to

verify the interest VaR and EaR, as well as

customer behavior models.

operational risk management

We plan to implement the KRI, a key risk

indicator whereby OR can be monitored

in real time (currently done monthly), to

enhance the timeliness of ORM and sup-

port risk management on business sites.

Requirements for checking OR can be

done prior to the close of business and

can be reviewed on the same day. Notices

from the real time indicator can be sent via

SMS to the general manager of the branch,

who can then check the appropriateness

of transactions made on that day and alert

the staff if necessary, thus helping to lower

OR.

Woori Bank wants to be the No.1 Bank in

Korea, and a vital part of this is creating

the very best in customer satisfaction. We

therefore undertake Bank-wide customer

satisfaction management based on me-

dium and long-term strategies that fully

reflect customer needs, customer satisfac-

tion analysis inside and outside the Bank,

and feedback from all our staff on a top

down or bottom up basis. The Bank’s

customer satisfaction unit consists of an

inverted pyramid oriented towards custom-

ers and staff on site, instead of the usual

corporate profit-oriented pyramid. Our top

priority is our customers, and everyone at

Woori Bank is aligned in the same direc-

tion.

CEO Lee, Soon Woo, who took the helm

in March 2011, unveiled a corporate slogan

“The Bank for Customer Convenience”

along with a series of management mea-

sures focused on customer first and site-

oriented management. We execute our

customer satisfaction program based on

specific strategies under the new slogan,

always aiming to be no. 1 in customer hap-

piness. These include a monthly phone

survey of customers who visited a branch

the previous day, to evaluate the service

they had received. We also reflect the voice

of the customer as submitted through vari-

ous channels to the ‘customer satisfaction

KPI’.

review of 2011 and plans for 2012

differentiated Cs programs

In 2011, Woori Bank held a differentiated

training session called Personal Image

Making(PIM) of the staff and thereby raised

awareness about the customer first mind-

set. This contributed to stronger customer

loyalty and improved business capabilities.

Moreover, the Bank shared customer feed-

back via video training on ‘Woori Action’,

and proposed active measures to improve

customer satisfaction.

happier CustomersOur top priority is the principle

of ‘Customers First’(customer

satisfaction). Woori Bank will enable

our customers to conveniently and

efficiently access all our services in

Korea and beyond. We will do this

by prioritizing them in everything

we do.

A training session called ‘Two-Day One-

Night Harmony’ was launched, and re-

ceived positive feedback from our staff. It

has been particularly effective at improving

internal communication and raising aware-

ness about the importance of a positive

attitude. In May 2011, 823 customer sat-

isfaction leaders participated in the ‘2011

Customer Satisfaction Leader Hanmaeum

Festival’ to boost morale and strengthen

customer satisfaction leadership.

We published the Service Webzine in 2011

to enhance ‘Customer First’ service, and to

raise our competitiveness by sharing infor-

mation. Heads of branches and other staff

greeted customers at all our branches,

thus improving our image with custom-

ers and contributing to a happy culture for

staff.

We also undertook a ‘Service Focus’, se-

lecting issues and themes every quarter

related to major services, reflecting them in

our service, and ensuring that customers

really were able to feel the change.

We have also conducted surveys to raise

customer satisfaction, and set up a Cus-

tomer Satisfaction Portal System and a

Cyber Warning System. The Customer Sat-

isfaction Portal System is to prevent cus-

tomer complaints and raise standards of

customer satisfaction, based on data from

branches, and to use Woori Bank’s exclu-

sive customer satisfaction and integrated

voice of the customer system to strengthen

marketing functions. The Cyber Warning

System monitors customer feedback in

real time, and thus improves service, pre-

vents customer complaints and improves

products and systems.

Creating a work Culture for Customer happiness

Our philosophy is that a bank where all

the staf f are happy makes customers

happy as well, and so we strive to facilitate

a happy work culture. In particular, we

garnered great feedback from our staff

on the congratulatory letters sent from

the Bank’s CEO to the staff who excel in

customer satisfaction, and on the program

for ‘Finding Partners in Customer Satis-

faction’ boosting morale and therefore, in

turn, boosting customer happiness. The

number of branches excelling in customer

satisfaction increased, which has further

encouraged our staff to strive in improving

customer satisfaction.

The Staff Satisfaction Center organized

various programs, such as ‘Happy Monday,

Reach out for Luck’, weekend trips, and a

‘one day meditation experience’. In 2012,

we plan to upgrade all customer-related

activities, including the branch environ-

ment, and continue to initiate projects that

befit us as a bank that has been inducted

into the Customer Service Hall of Fame.

prior reviews were completed regarding

major legal issues that might surface when

handling new products, whether legal

monitoring was implemented regularly for

In addition, we provide training material on

ethical management, such as our monthly

“Ethical Compliance Practices” manual,

containing important reminders and practi-

2011 review

Despite a challenging business environ-

ment in 2011, Woori Bank’s overseas op-

erations now have total assets of USD 11.3

billion, loans of USD 5.2billion and operat-

ing revenue for the year of USD 310 million.

This can be attributed to diversifying our

funding sources, and reducing the level

of low-profit assets. Our delinquency rate

stood at 1.29% as of 2011. Some of our

achievements were as follows.

strengthening the overseas network

Woori Bank launched three offices in 2011:

in In August, we opened St. Petersburg

branch in Russia, followed by a sub branch

in ZhangJiaGang, China and the Krakatau-

POSCO office in Indonesia. Our operations

in Chennai, India and São Paolo, Brazil

became a branch and a subsidiary respec-

tively to serve those new markets for us,

and we plan to open a branch in Sydney,

Australia.

We also plan to add 14 more independent

network worldwide, center ing around

existing branches: four of the Dhaka sub

branch and one service center in Bangla-

desh, two branches and four sub branches

of our Chinese subsidiary, and three sub

branches in Indonesia.

Building relationships with overseas financial institutions

2011 was a year when liquidity risk manage-

ment triggered by the European financial cri-

sis topped the agenda. Woori Bank therefore

expanded its number of foreign currency bor-

rowers through active marketing and building

relationships with overseas financial institu-

tions, and also receiving sufficient foreign

currency funds that contributed to effective

liquidity management.

Building relationships with overseas financial

institutions is critical as we have considerably

increased the frequency and scale of foreign

currency and international financial transac-

tions such as foreign exchange, trade finance

and treasury. Woori Bank now has a Financial

global BusinessWoori Bank is located in 15 countries

as of December 2011, with an 56

overseas network consisting of

12 branches, 5 local subsidiaries

(40 branches belonging to subsidiaries),

and 4 representative offices.

We plan to expand local subsidiaries

and branches, especially in emerging

regions with high growth potentials,

so that we can become a truly

global and competitive bank.

review of 2011

As the global financial crisis continued,

Woori Bank’s retail banking served as a base

for our banking operations. The retail bank-

ing division laid the foundations for solid

growth by securing liquidity, improving profit-

ability and increasing asset soundness. The

division was able to up-sell high-value prod-

ucts to mid-tier customers to maximize op-

erating income, increase low-cost deposits

and preemptively manage its risks. Another

important factor was increased profits from

sales in cooperation with sister companies in

the Woori Financial Group.

The key achievements in 2011 were the

expansion of the retail base account and

increases in high-yield customers. By at-

tracting new customers, including those in

schools and hospitals, corporate executives,

public officials and new staff at large enter-

prises, the number of high-yield customers

rose sharply. As a result of initiating busi-

nesses such as payroll transfer, credit cards

and automatic transfer of fees, core deposits

increased by KRW 1.2 trillion.

achieving group synergy

The Bank integrated the Woori Bonus Family

Membership preferencial customers services

to include the customers of Woori Aviva Life

Insurance and Woori Financial. Woori Bank

formed a business alliance with its sister

company Woori Financial in co marketing

products or sharing customers database,

thereby promoting intra-Group synergy.

This helped to diversify the profit base of

both companies while distributing risk over

a wider asset base. To this end, the Bank

jointly developed and soldedly co-marketed

products targeting automobile purchasers

as well as low-credit borrowers that are ineli-

gible to apply for loans in the banking sector

and introduced such products to affiliates of

the Group.

extending our reach

As of December 2011, Woori Bank operates

942 branches in Korea to provide complete

financial services to approximately 17 mil-

lion customers. The Bank’s 7,000 ATMs

and cash dispensers extend the company’s

reach while raising customer satisfaction and

delivering ‘any time, anywhere’ banking con-

venience. About 60 branches will be opened

in 2012, with a focus on getting closer to the

customer. Woori Bank’s efforts to expand

its service delivery channels are key com-

ponents in its strategy of building customer

loyalty and increasing customers access to

the broadest range of financial services.

retailBankingWoori Bank is aiming to be the

no. 1 retail bank in Korea by

securing liquidity, improving

profitability, raising asset soundness

and managing risk. We will make

continuous effort to attract retail

customers, and thus to establish a

stable base for growth.

plans for 2012

We aim to increase one million new custom-

ers to establish a stable base for growth

once the worst of the global financial crisis is

over. Specifically, we are targeting 400,000

new customers through the participation of

the Korean government and public agencies

in the Bank’s projects: a project in conjunc-

tion with the Ministry of Employment and

Labor to launch a bank-book that prevents

the seizure of unemployment allowances

by unauthorized persons; a project with the

Ministry of Health and Welfare to help with

medical fees to encourage a higher birth rate

in a country with a declining population; and

a project to launch a bank-book that prevent

the seizure of basic personal benefits given

to old-age pensioners. Other diverse prod-

ucts will be launched, including deposits,

loans, funds and pensions; these will suit

everyages from the teens to the sixties, and

we hope this will attract 200,000 customers.

Moreover, products customised according

to each relion will attract 100,000 customers

as well.

We also plan to expand operations in funds,

bancassurance, money exchange and trans-

fers, to raise non-interest income. Further-

more, we expected to dominate the market

in savings for housing subscriptions and

loans for subscribers by being re-selected

as a treasury bank for the National Housing

Fund, currently worth KRW 91 trillion.

magic 7 installment savingsWe launched Magic 7 Installment Savings in

July 2011. This offers a higher interest rate

than average savings depending on credit card

usage, so that customers can build up large

funds and we can offer them a higher inter-

est rate. The product is a hybrid of installment

savings and credit card services, which is the

first of its kind in Korea. Within six months of

its launch, the number of accounts reached

271,000 and the contracted amount hit KRW

2.4 trillion. These figures far exceed those of

similar products from other banks.

woori happiness Bank-bookIn April 2011, we launched a bank-book to

prevent the seizure of basic social security

benefits. This first of a kind product shows the

Bank’s commitment to citizen-friendly banking,

especially by exempting the socially vulnerable

from money transfer fees and fees for using

ATMs. As a result, Woori Bank received an

Award from the Ministry of Health and Welfare

in 2011.

private Banking

review of 2011

Woori Bank has targeted private bank-

ing (PB) as a core growth engine for the

medium to long term business expansion.

We are building strategies that will enable

us to register the highest-ever increase of

total assets under management in Korea,

and of consulting services for PB custom-

ers.

“Two Chairs” is Woori Bank’s exclusive

private banking brand, symbolizing our

one-on-one approach to personalized

service for high-income individuals. Woori

Bank operates 6 private banking centers

and 370 PB branches, all of which are

staffed and equipped to deliver custom-

ized one-stop f inancia l ser v ices. We

provide asset management consulting

services and conduct seminars on real

estate for prospective local customers

through overseas branches and subsid-

iaries, thereby providing PB services on a

global basis. Our private banking advisory

centers, with more than twenty specialists

in real estate, tax and overseas invest-

ment, are located in every major Korean

city. Consulting services on donation/

inheritance, succession at family busi-

nesses and taxation are available, along

with total services for real estate invest-

ment, market outlook, overseas invest-

ments and studying abroad. Woori Bank’s

advisory centers are now established as

Korea’s No.1 financial consulting service

providers.

The Bank also operates the PB Academy,

with the industry’s best curriculum for

fostering specialists in comprehensive as-

set management. The Academy has had

126 graduates over the past four years:

117 from Woori Bank, and 9 from Kwangju

Bank and Kyongnam Bank. These spe-

cialists are now responsible for delivering

top-quality PB services at the branch

level throughout the nation.

Private Banking at Woori Bank received

for two straight years the ‘Korea Luxury

Brand Award’ and the ‘Asia PB Award’.

Even in the af termath of the f inancial

crisis, and despite challenges such as

low interest rates and plummeting stock

prices in 2011, PB is maintaining growth

of some 8%.

plans for 2012

In 2012, we plan to offer upgraded spe-

cial services and comprehensive asset

management services for PB customers.

This will include services for our individual

customers of preference, their families

and even their companies. To this end,

we will provide a comprehensive asset

management platform, spearheaded by

the Wealth Management (WM) team. We

will expand the number of PB centers to

improve our sales capabilities for High

Net Worth (HNW) customers, and expand

our consulting model, offering genuinely

customized comprehensive asset man-

agement services.

We wil l a lso extend customer service

beyond expectations. We plan to add a

‘concierge service’ to the “Two Chairs”

service, providing life care services in-

cluding medical check-ups, hotel res-

ervations, sports and arts performance

t ickets, go l f lessons and home care

services. Moreover, the PB Academy will

be upgraded and expanded to secure

the Bank’s competitive edge. Training

courses covering wealth management,

inter-personal skills, consulting skills and

an understanding of our HNW custom-

ers’ lifestyles will be separated, so that all

courses are customized and specialized

according to different needs.

‘PB services beyond wealth management’

is the essence of Woori Bank’s Private Bank-

ing. In 2012, we will continue to upgrade our

PB services, with a constant focus on the

customer.

review of 2011

Woori Bank’s Small & Medium Corporate

SME-friendly product line-up that reflects our

SME customers’ diverse characteristics and

needs.

Despite difficulties at home and abroad, the

KRW 58.1 billion, to KRW 1,808.2 billion

in 2011 compared to KRW 1,750.1 billion

in 2010, thanks to an increase in customer

numbers of 49,000, and an increase in high-

16,000 year on year.

We enjoyed a successful year in liquidity

management, with an increase of KRW 5.5

its. In our loan segment, three loan products

recorded sales volume of KRW 1,217.2 bil-

lion, with total SME loans reaching approxi-

mately KRW 58 trillion by the end of 2011.

Of particular note, the ‘Woori Big Chance

ratings of BBB- and above, recorded a sales

volume of approximately KRW 1 trillion.

We also offered 125 cases of consulting

services, and their upgraded quality truly

satisfied our customers. These site-oriented

customized consulting services for SME

customers were the first to be offered in the

Korean banking sector since 2001.

We now seek to prioritize customer satis-

We will strive to strengthen relationships with

existing customers, and increase the volume

Corporate Banking

review of 2011

The Corporate Banking Division has a vi-

sion of becoming the No.1 banker in Korean

industry, and becoming a leading bank in

Asia over the medium to long-term. To this

end, the division has expanded its one-stop

services in cooperation with sister compa-

nies. Relationships with the largest corpo-

rate customers are strengthened through

the Woori Diamond Club, a meeting of the

heads of the country’s largest multination-

als. New product development continued

apace, with the launch of customized

products that cater to customer needs and

changing markets.

According to information compiled by the

FSS in 2011, Woori Bank was designated

as the main creditor bank for 15 of Korea’s

37 largest corporate groups, more than any

other bank, including world-leading compa-

nies such as Samsung, LG and POSCO.

Quantitative indicators were also strong.

Total assets amounted to KRW 29.3 trillion,

along with operating revenue of KRW 1 tril-

lion, net income of KRW 607.5 billion and

export/import volume of USD 218.8 billion.

The net interest margin was 2.09%. More-

over, we contributed to the national econo-

my through support for partner SMEs, while

also facilitating cooperation between large

enterprises and SMEs, and strengthen-

ing the Bank’s roles in Corporate Banking.

Strong performance was achieved in the

sales of the Partnership Loan for Large En-

terprises, the Partnership Guarantee Loan

for Large Enterprises, and the Settlement

Fund Loan for Partner Companies.

plans for 2012

In 2012, we plan to attract high-yield as-

sets and customers, maximize synergy by

offering multiple Woori Group products to

high-yield partner companies, and facilitate

the transactions of corporate executives.

We will implement customer-oriented site

management, helped by our outstanding

business capabilities and our strong rela-

tionships within Corporate Banking.

review of 2011

Since Woori Card was merged into Woori

Bank to form the Credit Card Division in

2007, it has succeeded in building asset

soundness thanks to conservative and

stable business operations, especially in the

aftermath of the global financial crisis and

the subsequent market slowdown.

In 2011, the Bank focused on maintaining

asset soundness and improving business

operations, while actively taking part in the

public bid market1) and seeking to attract

more customers. We rationalized the card

review standard and optimized the limits. We

also broadened the customer base by ex-

panding the market for check cards. Syner-

gies were created with increases in deposits

and card sales through ‘MAGIC 7 Installment

Savings’, a product that offers additional in-

terest for increases in card usage.

We launched the ‘Woori Children-Love

Card’ as the operator of the government’s

nursery subsidy program, and also launched

the ‘Woori V Check Green Card’ providing

economic benefits for green living and con-

sumption. Another new product was ‘Woori

V Card Oil-100’, which offered oil price dis-

counts.

Services to enable automatic transfers for

telecommunication and transportation fees

led to higher customer retention rates. We

also classified the criteria for our VIP pro-

gram (V Club) and provided services accord-

ingly, focusing on attracting and retaining

high-yield customers. We also focused on

active responses to market changes and the

need for customer convenience by providing

credit card inquiry and transaction services

through smart phones.

As of December 31st, 2011, Woori Card’s

market share was sixth in the country. The

annual sales volume was KRW 39.4 trillion,

up 10.0% year-on-year, while the number

of credit cardholders (including check card-

holders) increased 6.5%, to 11.7 million.

plans for 2012

In 2012, we will focus on increasing the num-

ber of high-yield customers, expanding our

participation in the public bid market and es-

tablishing the infrastructure for mobile cards.

New systems will be out in place to offer a

smart business environment within branches.

We will also focus on enhancing our competi-

tiveness by maximizing the operating efficiency

of each division, enhancing profit & loss man-

agement, and strengthening the analytical skills

for membership data.

We will do our best to raise membership and

sales volumes through strong customer man-

agement and marketing. We will also strive to

increase high-yield assets through the reten-

tion of high-yield customers, the optimization

of risk management, the development of finan-

cial hybrid products with more robust financial

functions, the exploration of customizeable

markets, the enhancement of our brand image,

and the utilization of a new card system.

review of 2011

The credit crunch, stemming from the on-

going global financial crisis, worsened again

in 2011 due to the European financial crisis.

However we have sold and written off non-

performing assets in construction and ship-

building, and have instead focused on high

end customers for providing term loans and

M&A financing.

We also built asset soundness by disposing

of low-yield assets and assets at risk of de-

fault. We improved the profitability of assets

by increasing the volume of Won denomi-

nated loans, especially for commercially vi-

able projects.

The IB Division holds assets worth KRW

13.3 trillion as of end-2011(including off-

balance sheet items), consisting of loans of

KRW 6.1 trillion, securities of KRW 2.0 tril-

lion and off-balance sheet items of KRW 4.9

trillion. Recently, invested high yield loans

and securities have been recovered which

enabled us to receive sizeable amount of

dividend and profit on sale.

plans for 2012

The domestic IB market in 2012 is expected

to suffer from the ongoing European fi-

nancial crisis, slowing Chinese economic

growth, and export reductions, so on the

whole, improvement in the economic and

financial environment is not likely. There will

therefore be more disposal of assets under

corporate restructuring to liquidate non-

core businesses, increased corporate M&A

financing, and an overall focus on new busi-

nesses to diversify our corporate business

operations for medium to long-term growth.

A positive sign is that there will be more

demand in social overhead capital(SOC) as

the government makes increasing attempts

to build social infrastructure facilities. None-

theless, the outlook for real estate devel-

opment projects including publicly-placed

large real estate PF is yet to recover.

In 2012, Woori Bank will expand IB-related

f inancing for corporate clients. We will

continue financial arrangements for tra-

ditional SOC projects such as BTO and

BTL by marketing on corporate clients and

strengthening our networks. We will also

increase fee income by arranging and par-

ticipating in M&A financing.

We also plan to secure new income sources

in the medium to long-term by tapping into

power generation and renewable energy

markets. The IB Division will position itself

as Korea’s leading investment bank through

the strategic alignment of the two busi-

nesses, corporate banking and investment

banking.

Woori Bank succeeded in Investment

Banking (IB) by selectively initiating

business while considering overall

profitability, raising asset soundness

and improving the profitability

of assets currently held. We will

continuously expand IB services for

corporate clients, to become

Korea’s leading operator of the

Commercial & Investment Banking

(CIB) model.

review of 2011

Woori Bank maintains a dominant market

share in trading & derivatives in all fields

related to the financial markets, such as

foreign exchange dealing, derivatives, invest-

ment in securities and short-term financing.

We are particularly competitive in derivatives

transactions like forwards, swaps and op-

tions based on diverse underlying assets (in-

terest rates, foreign exchange, equities and

commodities) and maintain a solid presence

as a market maker.

The Financial Market Business Unit in-

creased financing through foreign currency

derivatives such as Samurai Bond to take

preemptive measures against spillover ef-

fect from the Euro zone crisis. We became

the first Korean bank to issue subordinated

bonds in foreign currencies and gain inves-

tor’s confidence in its strong capital sound-

ness and credit ratings. We responded ac-

tively to the drop of U.S.A. credit ratings by

securing liquidity in foreign currencies. We

were thus able to meet the FSS’s prescribed

liquidity ratio and mid to long-term financing

ratio for foreign currencies. We also built on

our dominance in the derivatives market by

strengthening derivatives trading based on

predictions of market variables in policies,

and supply and demand forecasts. Woori

Bank has developed a fully diversified port-

folio of foreign currency derivatives, includ-

ing the Mexican Peso, South African Rand,

Polish Zloty, Russian Ruble and Chinese

Yuan. One important breakthrough was the

development of products offering 24-hour

hedging of commodity price risk, now avail-

able through the Bank’s Night Desk for com-

modity derivatives. We also offer services

to cover overnight exchange rate risks by

opening our London Desk when Korean for-

eign exchange desk closes.

plans for 2012

The business goal of the Financial Market

Business Unit is to achieve sustainable growth

through risk management, and to do so de-

spite the economic uncertainties at home and

abroad. To achieve this goal, we will implement

the following strategies:

managing liquidity

We will optimize liquidity management by

controlling our trading positions and maintain-

ing the loan-to-deposit ratio below 100% of

the average monthly balance. We will reduce

the concentration of USD in our portfolio

by diversifying funding into currencies such

as Thai Baht, Malaysian Ringgit and Swiss

Francs. Moreover, we plan to take preemptive

measures in responding to financial markets

and adapt to regulatory changes in various

ways: reviewing fund variation factors and

setting responses on a daily, weekly and

monthly basis, monitoring regulatory changes

such as amendments to the Regulation on

the Supervision of Banking Business, manag-

ing the liquidity ratio and continuously seeking

to reduce any fund imbalances.

expanding the Base of high-yield Customers

We plan to broaden our base of high-yield

customers by attracting new derivatives cus-

tomers, increasing the transaction volume

with institutional investors and also enhancing

transactions with existing high-yield custom-

ers. We will more fully utilize internal sales

channels such as subsidiaries, overseas

branches and other business units that may

lead to cross-sales marketing while minimize

expected customer defections due to mer-

chant banking licence expiration.

strengthening risk management

We will reduce operational risks by continu-

ously improving our IT systems, and by re-

ducing counterparty credit and payment risks

through the liquidation of over-the-counter

derivatives. Moreover, all our product struc-

tures will take risk into account in developing

new product, and in minimizing market risk

through preemptive risk management.

retirement pensions

review of 2011

Retirement pension products are sold us-

ing a structure whereby subscribers can

accumulate retirement annuities separately

from their employer. The same sales mech-

anisms are used by all retirement pension

companies.

The Bank launched the Happy Life Bank-

book for retirement pension subscribers, a

first product of its kind in Korea. The prod-

uct enables subscribers to conveniently

access their retirement annuities as they

accumulate their pension, which is the key

concern of most subscribers, and they

can check their bank-book to see how the

funds are managed. The Bank has also es-

tablished the Retirement Pension Research

Institute, in which the Bank coordinates its

wide-ranging advisory services on pension

asset management, and offers related con-

sulting services. In addition, in compliance

with the government’s revision of the Work-

ers’ Retirement Wage Guarantee Act, we

upgraded our pension asset management

systems. We also offer good customer ser-

vice, and make sure that all product sales

are appropriate, by providing updates and

notifications to subscribers through the

Bank’s Happy Call System.

In 2011, Woori Bank’s pension deposits

climbed KRW 1.86 trillion, to KRW 4.33 tril-

lion. The number of joined companies en-

joyed impressive annual growth of 44.3%,

rising to 17,754. Individual subscribers were

attracted in even greater numbers, increas-

ing 57.3% or 243,861, to reach 669,487 at

year-end 2011.

plans for 2012

The retirement pensions market used to be

quite small, due to a lack of awareness among

both employers and employees. However,

since the adoption of the retirement pension

system in December 2005, the market has

doubled every year. Woori Bank is striving to

secure a stable customer and profit for a long

term by taking an early lead in the retirement

pensions market.

We believe that, because retirement pensions

are the foundation for post-retirement life, it is

critical for us to staff our team with employees

who are true experts in this area. Our goal

is to become No.1 in the retirement pension

market by building our strengths in corporate

banking, creating a well-organized marketing

unit, diversifying the product range and mak-

ing sure all funds are professionally managed.

Woori Bank offers socially responsible banking services by supporting those who might be struggling financially, the socially vulnerable and people who might not have access to banking services. We also offer microcredit services that have helped a whole new stratum of entrepreneurs who did not previously have access to funding.

Woori Bank’s Miso-credit is a Korean-style Microcredit that helps those who cannot access institutional financial funds, and

also helps companies in starting up a business or managing their funds. Woori Bank led the founding of the Woori Miso

Financial Foundation with contributions from affiliates of Woori Financial Group that contributed KRW 10 billion a year for five

years. The foundation has established channels in 8 regions nationwide, to support small-scale entrepreneurs in starting up

a business or managing their finances. The purpose of the Foundation is to support those with low income and limited credit

to be financially self-sufficient, thus enhancing the stability and comfort of their lives.

To ensure fairness in its operations, the Foundation’s outside executive directors consist of a priest from the Council of

Catholic Social Welfare, a professor at the Sociology and Welfare Department of Soongsil University, and a director of a

social welfare center. The Foundation’s 8 branches have 27 staff in total, to ensure the best support for those in need.

925 cases,

KRW17.4 billion The number of microcredit services extended as of

2011-end amounting to 925 cases, and the amount

provided as microcredit is 17.4 billion

RevieW of 2011

In 2011, our goal was to serve as a role model in the microcredit sector, and to increase the number of recipients of

microcredit. As a result of reaching out to those in need and developing products which cater to them, we were proud to

process 925 cases worth KRW 17.4 billion in 2011, bringing the overall totals to 1,413 cases worth KRW 22.2 billion.

In particular, we launched products tailored for single-parent families, along with customized products for small-scale

entrepreneurs involved in the delivery business. We visit the people who need our services, to make sure they get the most

useful product, in the most effective way. In the delivery business, our new microcredit product aims to resolve a shortage

of delivery vehicles and other logistical challenges while giving support through collaboration with the Ministry of Land,

Transport and Maritime Affairs, and thereby guarantee a stable business environment for small-scale delivery entrepreneurs.

As part of our microcredit services, we operate the Woori Microcredit Volunteer Team. This team not only extends financial

support but also gives practical advice to recipients in how to be financially independent. The team is comprised of staff

from Woori Bank and Woori Financial, as well as specialists including lawyers, tax attorneys, accountants and management

consultants, working alongside ordinary citizens, and college students. Their diverse professional knowledge and consulting

services on business start-up, management, marketing, law, taxation and accounting for recipients of our microcredit

services enable them be fully self-sufficient.

In 2011, we launched a sub-branch within Jungnang-gu Office and Yong-in branch, so that we can expand our microcredit

services.

plans for 2012

The goal for 2012 is to expand the support that Woori Bank may give to those in need through microcredit. So that

microcredit services can be available on-site, we will support merchants in traditional markets through an agreement with

a traditional market merchant association, and expand the scope of recipients to include entrepreneurs involved in making

keys and traditional rice cakes. We are also opening two more branches to increase access for customers.

We will examine and share case studies of business success among our loan recipients, so that other recipients gain

confidence in conducting their own business and learn from the best practices.

As a company that cherishes its people, Woori Bank does its utmost to create a great workplace, so that staff can work happily, and customers benefit from that happiness. In 2011, we strived to achieve labor-management harmony, and increased welfare benefits for all. We will continue to focus on our people in 2012.

RevieW of 2011

improving employee welfare Benefits

In 2011, Woori Bank got very positive feedback from staffs by launching and improving diverse programs for staff welfare

benefits and internal communication. These programs were as follows:

a family weekend journey : This program, launched in July 2011, mainly focuses on the families of our

staff. The purpose of these outdoor programs is to encourage love within families, and to recharge body and

mind. Held on the fourth Saturday every month, participants had wetland experience in July, went grape picking

in August, and chestnut picking in September. The program was amongst the Bank’s top ten news highlights for

2011 as a result of the quality of feedback it got.

encouraging a happy monday : The ‘Happy Monday’ program aims to create a corporate culture where

all staff is eager for Mondays to come. Every Monday, a lucky draw is made and the selected branches will get

plenty of snacks delivered to them. There are also other elements of ‘Happy Monday’ that put smiles on the

faces of staff members, and it seems to have succeeded; the program was a huge success, and over 30,000

staff participated.

heart-to-heart dialogue with new staff : ‘Heart-to-heart dialogue with new staff’ is a program to take

notes of complaints and feedback from new staff. Because the program is only open to new hires, this enables

us to listen closely to what they say. and their words are heard at a more honest and deeper level – and, because

Woori Bank has branches nationwide, the program visits new staff at their site. These efforts have therefore

gained a huge positive feedback.

increasing the number of medical Check-up Centers : The number of medical centers available for

the staff annual check-up increased from 41 to 46. The number of items available for the medical check-up also

increased, which greatly enhanced the overall level of satisfaction.

free rental of a wedding hall : The wedding hall at HQ is rented out for free to staff at weekends. It offers

a large hall and luxurious decoration, and has received great feedback from staff – especially from brides! The

luxurious bride’s room and pyebaek room(post-wedding ceremony ritual) would make any event very special,

even compared to the most luxurious hotel wedding halls. The free rental saves hugely on wedding costs for

staff, and imbues a sense of community at the Bank.

harmonious laBor-management Harmonious labor-management is important in making a good workplace. We forged a strong labor-management consensus

by applying the amended Labor-Management Act, such as introducing a time-off system for the executives of the labor

union, and a preferential scheme for full-time unionists.

We also reached agreements on industry-specific bargaining and industry-specific wage negotiations. As a representative of

the Korean banking sector, we fulfilled our role in raising wages by 4.1%, and restoring the salaries of new employees.

Moreover, we have innovatively enhanced labor management issues to a long term base and increased our competiveness. An example is the March 2011, MOU implemating agreement of labor management regarding enhanced treatment of employees. This was measured in a quarterly base, but recently was amended to a yearly base.

plans for 2012

In 2012, Woori Bank will continue the open dialogue and promote harmony between labor and management, to create the best possible working environment. Professional seminars on labor-management relations will be held officially so that participants can foster expertise in advance, and prevent unnecessary labor-management disputes. Lastly, we will form a joint labor-management task force team to improve HR and training systems.

woori happiness society program : Our ‘Woori Happiness Society Program’ sponsors the socially vulnerable in the community. This volunteer program is closely aligned with the community on a regular basis, forging sisterhood relationships with social welfare organizations and local childcare centers near our HQ and branches nationwide.

On November 7th, 2011, Woori Bank’s volunteer group, including CEO, took part in a marathon alongside with the visually impaired; staff members formed teams with disabled participants and their success as a team broke down walls and forged social integration. Building on these successes, we will continue to hold the 4th Sports Festival and Marathon for the Disabled in 2012.

volunteering with rural & fishing villages, and protecting Cultural properties : Our ‘One Company, One Village’ sponsorship program encourages active exchange and shared growth between urban and rural regions. The program marked its 8th anniversary in April 2012 by supporting a village in Korea’s Gyeonggi Province. We offer supports such as volunteering during harvests, markets for direct sales of agricultural products, rural village experiences for staff and customers, village refurbishment and income raising in rural villages. We also forged the ‘One Company’ One Fishing Village’ program with Mongsan-ri in South Chungcheong Province, and the ‘One Company’ One Mountain’ program with Namsan Mountain in Seoul for environmental preservation and natural protection.As part of our heritage, we have signed a contract to protect Hongyuneung, under our ‘One Company’ One Cultural Property’ program. Hongyuneung is a UNESCO-designated World Cultural Heritage site, and one of Korea’s most important cultural properties. It is the tomb of Korea’s Emperor Gojong, and also of King Sunjong, who paved the way for Daehan Cheonil Bank, the forerunner of Woori Bank, to be established, sponsoring it with imperial funds so that a national bank could take root. We regularly conduct activities to protect Hongyuneung, and include a tribute ceremony as part of new staff training, to enhance their appreciation of company history.

woori art Contest : The Woori Art Contest is Korea’s top art contest for artistically-inclined children. It celebrated its 17th anniversary in 2011, when a total of 45,000 elementary, middle and high school students and kindergartners took part; we also held an art event for children from Southeast Asia, who sometimes lacks opportunities for such events in Korea. We are also active in promoting educational and social programs such as offerings economics classes to children and classes of basic money care for North Korean defectors. The children’s class includes a field trip to Woori Bank Museum and opening a new bank-book, so that the children can enjoy a hands-on money-based experience.

multicultural festivals for foreigners : We took part in and supported various events for foreigners to raise the Bank’s image as a global leading bank: ‘2011 Korea Grand Sale’, ‘Easter Festival for Foreign Workers’, ‘2011 Information Fair’, ‘Mongolia Naadam Festival’ and ‘Mr. & Ms. Filipino Culture Thanksgiving Festival.’ As such, we strived to do the best in social responsibilities as a bank specialized in Forex.

increasing the Culture of donations : Our staff is the driving force for increasing Woori Bank’s culture of donation. They voluntarily give part of their monthly wages to the Woori Love Fund and the Woori Children Love Fund. We also offer ‘Woori Love e-Sharing’, whereby customers can donate by transferring money via Internet banking, encouraging a culture of small-scale donations. We operate the ‘Woori Love e-Sharing’, a point-based donation program that donates some of the points accumulated when using credit cards. We also support Myeonghwiwon, a social welfare corporation.

Summary of Management Performance

2011 was a year of continued challenges, with uncertainties from the European financial crisis, a downgrade in USA credit rating, and concerns about

inflation at home. Despite these setbacks, the Bank’s 2011 operating income was KRW 2,683 billion, up 79.1% year-on-year, with net income of KRW

2,069 billion, up 63.9%. This was attributable to continuous efforts to improve profitability, income diversification, including increased fee and dividend

income, improving asset soundness, and increases in interest income.

Impairment losses on loans and other credit

The Bank has strived to spearhead a culture which raises accountability for NPLs, and prevents defaults, to improve overall asset soundness. In 2011,

impairment losses totaled KRW 1,817 billion, down significantly, by 27.2% year-on-year. This is a result of the increase in impairment losses on payment

guarantees of KRW 100 billion being considerably more than balanced by a drop in impairment losses on loans of KRW 779 billion.

SG&A Expenses

The Bank’s SG&A expenses in 2011 went up 12.8% due to higher expenses across the board, with wages in particular up 21.1%. Although the absolute

amount increased, however, the SG&A expense ratio fell, thanks to the Bank’s cost saving efforts.

Total assets at year end were 6.1% higher at KRW 242,472 billion, up KRW 13,917 billion, making Woori Bank the second-largest domestic bank as

measured by total assets. Loans and bonds receivable increased by KRW 14,278 billion year-on-year, and most asset items increased over the year,

although financial assets dropped by KRW 2,245 billion.

Asset Quality

Despite the increase in total loans, NPLs for the year were down significantly year-on-year, by 48.2% to KRW 2.9 trillion. This was due to the Bank’s

continuing efforts to build asset soundness, improve the concentration of high-volume loans and spreading a culture of increasing accountability for

preventing defaults. Moreover the Delinquency Ratio fell, down to 0.82%.

FINANCIAL REVIEW

To the Shareholder and the Board of Directors of Woori Bank

We have audited the accompanying consolidated financial statements of Woori Bank and its subsidiaries (the “Group”). The financial statements

consist of the consolidated statements of financial position as of December 31, 2011, December 31, 2010 and January 1, 2010, respectively, and the

related consolidated statements of comprehensive income, consolidated statements of changes in equity and consolidated statements of cash flows, all

expressed in Korean won, for the years ended December 31, 2011 and 2010, respectively. The Group’s management is responsible for the preparation

and fair presentation of the consolidated financial statements and our responsibility is to express an opinion on these consolidated financial statements

based on our audits.

We conducted our audits in accordance with auditing standards generally accepted in the Republic of Korea. Those standards require that we plan

and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes

examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting

principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our

audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Group as of December 31,

2011, December 31, 2010 and January 1, 2010, respectively, and the results of its operations and its cash flows for the years ended December 31, 2010

and 2011, respectively, in conformity with Korean International Financial Reporting Standards (“K-IFRS”).

Accounting principles and auditing standards and their application in practice vary among countries. The accompanying consolidated financial statements

are not intended to present the financial position, results of operations and cash flows in accordance with accounting principles and practices generally

accepted in countries other than the Republic of Korea. In addition, the procedures and practices utilized in the Republic of Korea to audit such financial

statements may differ from those generally accepted and applied in other countries. Accordingly, this report and the accompanying consolidated

financial statements are for use by those knowledgeable about Korean accounting procedures and auditing standards and their application in practice.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

(1) Basis of financial statement presentation.

The Group has adopted K-IFRS from the fiscal year beginning on January 1, 2011 and the accompanying consolidated financial statements are prepared

on K-IFRS. In accordance with K-IFRS 1101 ‘First-time Adoption of International Financial Reporting Standards ‘, the transition date to K-IFRS is January

1, 2010. An explanation of how the transition to K-IFRS has affected the financial position as of January 1, 2010 (date of transition), December 31,

2011 and December 31, 2010, and comprehensive income for the year ended December 31, 2011 and 2010 of the Company is provided in Note 47

“Transition Effects of K-IFRS.”

The Group maintains its official accounting records in Korean Won and prepares consolidated financial statements in conformity with K-IFRS, in the

Korean language (Hangul). Accordingly, these consolidated financial statements are intended for use by those who are informed about K-IFRS and

Korean practices. The accompanying consolidated financial statements have been condensed and restructured into English with certain expanded

descriptions from the Korean language financial statements.

Major accounting policies used for the preparation of the consolidated financial statements are stated below. Unless stated otherwise, these accounting

policies have been applied consistently to the financial statements for the current period and accompanying comparative period.

The company’s financial statement has been filled out based on the historical cost method except for specific non-current assets and certain financial

assets. The preparation of consolidated financial statements under K-IFRS requires the application of certain accounting estimates and the Group

prepared its financial statements by management judgement for critical accounting estimates.

FINANCIAL REVIEW

The accompanying consolidated financial statements were approved by the board of directors on March 7, 2012.

(2) Basis of consolidation

1) Subsidiary

An entity which the Group (including special purpose entities) has power to govern the financial and operating policies is considered a subsidiary. In

general, an entity which the Group has over 50% voting power in is considered a subsidiary.

Special purpose entities established for certain limited purposes may be considered as a subsidiary of the Company; even though the Company may

have less than 50% of the voting power, if the Company has the decision-making power over the special purpose entity’s activities, risk and benefit.

The existence of the potential voting power available to exercise or to convert, presently, is considered when evaluating whether or not the Group has

control over an entity. An entity is included in the consolidation, as a subsidiary, once such control is established, while it is excluded from consolidation

once it is loses such control. .

Acquisitions of subsidiaries are accounted for using the acquisition method. The consideration for each acquisition is measured at the aggregate of

the fair values (at the date of exchange) of assets given, liabilities incurred or assumed, equity instruments issued by the Group and acquisition-related

costs. At the acquisition date, the identifiable assets acquired, liabilities and contingent liabilities are recognized at their fair value at the acquisition

date without reference to non-controlling interests. Any excess of the cost of acquisition over the Group’s share of the net fair value of the identifiable

assets, liabilities and contingent liabilities of a subsidiary recognized at the date of acquisition is recognized as goodwill; if less, the difference is directly

recognized as other comprehensive income.

When the Group transacts with each other, unrealized profits and losses resulting from the transactions are eliminated. When a subsidiary of the Group

uses another accounting principle other than that of the Group’s, necessary adjustments are made to the financial statements for the Group’s purposes.

2) Non-controlling interests

The components of net income and other comprehensive income are attributed to the owners of the Group and the non-controlling interest holders.

Total comprehensive income of subsidiaries is attributed to the owners of the Group and to the non-controlling interest holders, even if this results in

the non-controlling interests having a deficit balance. Changes in the Group’s ownership interests in subsidiaries that do not result in the Group losing

control over the subsidiaries are accounted for as equity transactions.

(3) Investments in associates

An associate is an entity over which the Group has significant influence but does not have direct or indirect control over. Significant influence is generally

presumed to exist when the Group holds 20% or more, but less than 50%, of the voting rights. Such investments in associates are measured an

acquisition cost at acquisition date and since then are accounted for using the equity method. The identifiable goodwill (net book value) is included in

investment amounts in associate.

The Group’s interests in its associate’s income are recognized in the statement of consolidated comprehensive income. The changes in the associate’s

retained earnings are recognized by the Company as retained earnings. However, when the Company’s share in an associate changes due to a capital

increase or decrease of the associate, such changes are recognized in other equity (change in interests of equity method securities).

If the Group’s share in an associate’s accumulated loss equals or exceeds the Group’s equity interest, including unsecured receivables, in the associate,

the Group suspends further recognition of its share of the associate’s loss. Unless in circumstances when the Group guarantees or is obligated to pay

the associates payables.

(4) Segment reporting

An operating segment is the level of business activity at which management reports to chief operating decision maker, for decision making purposes.

In addition, the chief operating decision maker is responsible for evaluating the resources distributed to and the performance of an operating segment.

(5) Accounting for foreign currencies translations

1) Functional currency and presentation currency

The individual financial statements of each Group entity are presented in the currency of the primary economic environment in which the entity operates

(its functional currency). The consolidated financial statements are expressed in Korean Won.

2) Translation of foreign currencies transactions and balances at the end of reporting period

In preparing the financial statements of the individual entities, transactions in currencies other than the entity’s functional currency (foreign currencies)

are recognized at the rates of exchange prevailing at the dates of the transactions. At the end of each reporting period, monetary items denominated

in foreign currencies are retranslated at the rates prevailing at that date. Exchange differences on monetary items that qualify as hedging instruments

in a cash flow hedge and form part of the Group’s net investment in a foreign operation are recognized in equity.

The Company is recognizing amortized cost and exchange rate variation effect as gains and losses of current period and the variation on the fair value

as other comprehensive gains and losses, respectively, both of which are effect of monetary securities of foreign currencies classified as available-for-

sale financial instruments. And the company is recognizing the variation on fair value and exchange rate variation effect of non-monetary securities of

foreign currencies classified as available-for-sale financial asset, as other comprehensive gains and losses.

3) Foreign currencies translation

Financial position and operating results of the Group are translated into the Group’s reporting currency as follows:

Description

Statement of consolidated finan-cial position

The assets and liabilities are translated at the exchange rate prevailing at the end of the reporting period. Equity is translated at exchange rate at the time of acquisition.

Statement of consolidated com-prehensive income

The statement of consolidated comprehensive income is translated at the average exchange rates for the period, unless exchange rates fluctuated significantly during that period, in which case the exchange rates at the dates of the transactions are used.

(6) Cash and cash equivalents

Cash and cash equivalents consist of cash on hand, demand deposits and short-term, highly liquid investments that are readily convertible to known

amounts of cash and which are subject to an insignificant risk of changes in value.

(7) Financial assets and financial liabilities

1) Classification of financial assets

Financial assets are classified into the following categories depending on the nature and purpose of possession: financial assets at ‘fair value through

profit or loss’ (“FVTPL”), loans and receivables, available-for-sale financial assets (“AFS”), and held-to-maturity investments (“HTM”).

FINANCIAL REVIEW

a) Financial assets at FVTPL

Financial assets are classified at FVTPL when the financial asset is either held for trading or designated at FVTPL. A financial asset is classified as held

for trading if the following criteria are met:

acquired or incurred principally to sell or repurchase during a short period of time

part of a portfolio of identified financial instruments that are managed together and for which there is evidence of a recent actual pattern of short-term

profit-taking

a derivative (except for a derivative that is a financial guarantee contract or a designated and effective hedging instrument)

A financial asset other than a financial asset held for trading may be designated as at FVTPL upon initial recognition if:

such designation eliminates or significantly reduces a recognition or measurement inconsistency that would otherwise arise; or

the financial asset forms part of a group of financial assets or financial liabilities or both, which is managed and its performance is evaluated on a fair

value basis, in accordance with the Group’s documented risk management or investment strategy, and information about the grouping is provided

internally on that basis; or

it forms part of a contract containing one or more embedded derivatives, and K-IFRS 1039 “Financial Instruments: Recognition and Measurement”

permits the entire hybrid (combined) contract to be designated as at FVTPL

b) Loans and receivables

AFS financial assets are those non-derivatives financial assets that are either designated as AFS or are not classified as ‘financial assets at FVTPL’, ‘HTM

investments’ or ‘loans and receivables.’

c) AFS financial assets

AFS financial assets are those non-derivatives financial assets that are either designated as AFS or are not classified as ‘financial assets at FVTPL’, ‘HTM

investments’ or ‘loans and receivables.’

d) HTM financial assets

Non-derivative financial assets with fixed or determinable payments and fixed maturity dates that the Group has the positive intent and ability to hold

to maturity are classified as HTM financial assets

2) Classification of financial liabilities

Financial liabilities are classified as either financial liabilities at FVTPL or other financial liabilities measured at amortized cost.

a) Financial liabilities at FVTPL

Financial liabilities are classified at FVTPL when the financial liabilities is either held for trading or designated at FVTPL. A financial liability is classified as

held for trading if the following criteria are met:

acquired or incurred principally for the purpose of selling or repurchasing it in the near term

part of a portfolio of identified financial instruments that are managed together and for which there is evidence of a recent actual pattern of short-term

profit-taking

a derivative (except for a derivative that is a financial guarantee contract or a designated and effective hedging instrument)

A financial liability other than a financial liability held for trading may be designated as at FVTPL upon initial recognition if:

such designation eliminates or significantly reduces a recognition or measurement inconsistency that would otherwise arise; or

the financial asset forms part of a group of financial assets or financial liabilities or both, which is managed and its performance is evaluated on a fair

value basis, in accordance with the Group’s documented risk management or investment strategy, and information about the grouping is provided

internally on that basis; or

it forms part of a contract containing one or more embedded derivatives, and K-IFRS 1039 “Financial Instruments: Recognition and Measurement”

permits the entire hybrid (combined) contract to be designated as at FVTPL

b) Financial liabilities measured at amortized costs

Financial liabilities that are not classified as at FVTPL are measured at amortized costs. Deposits and debt securities that are not designated as at FVTPL

are classified as financial liabilities measured at amortized costs.

3) Recognition and Measurement

Standard trading transaction of a financial asset is recognized at the date of transaction when the Group becomes a party to the contractual provisions

of the asset. All types of financial instruments, except financial assets/liabilities at FVTPL, are measured at fair value at initial recognition plus transaction

costs that are directly attributable to the acquisition (issuance). Financial assets/liabilities at FVTPL are initially recognized at fair value and transaction

costs directly attributable to the acquisition (issuance) are recognized in the statement of comprehensive income.

Financial assets/liabilities at FVTPL and AFS financial assets are subsequently measured at fair value. HTM financial assets, loans and receivables, and

other financial liabilities are measured at amortized costs using the effective interest rate method.

Interest income and expense in accordance with financial assets and liabilities are recognized in profit or loss on an accrual basis using the effective

interest method.

Gains or losses arising from changes in the fair value of the financial assets/liabilities at FVTPL are presented in the statement of comprehensive income

during the period in which they arise. Changes in the fair value of AFS financial assets are measured in other comprehensive income.

Dividends income of financial assets at FVTPL and AFS financial assets is recognized in profit or loss when the Group’s right to receive the dividend is

established.

AFS financial assets recognize cumulative fair value adjustment, which is previously recognized in the equity, in profit or loss when disposing of assets

or recognizing impairment loss.

4) Derecognition of financial assets and liabilities

The Group derecognizes a financial asset when the contractual right to the cash flows from the asset is expired, or when it transfers the financial asset

and substantially all the risks and rewards of ownership of the asset to another company. If the Group neither transfers nor retains substantially all the

risks and rewards of ownership and continues to control the transferred asset, the Group recognizes its retained interest in the asset and an associated

liability for amounts it may have to pay. The Group derecognizes financial liabilities when, and only when, the Group’s obligations are discharged,

cancelled or they expire.

FINANCIAL REVIEW

(8) Offsetting financial instruments

Financial assets and liabilities are presented net in the statement of financial position when the Group has an enforceable legal right to set off and an

intention to settle on a net basis or to realize an asset and settle the liability.

(9) Impairment of financial assets

1) Assets carried at amortized costs

The Group assesses at the end of each reporting period whether there is any objective evidence that a financial asset (or a group of financial assets) is

impaired. A financial asset (or a group of financial assets) is regarded as impaired when there is objective evidence of impairment loss as a result of one

or more events (hereinafter the “loss event”) that occurred after the initial recognition and the loss event has an impact on the estimated future cash

flows of the financial asset.

The criteria used to determine whether there is objective evidence of impairment include:

significant financial difficulty of the issuer or obligor; or

a breach of contract, such as a default or delinquency in interest or principal payments; or

the lender, for economic or legal reasons relating to the borrower’s financial difficulty, granting to the

borrower a concession that the lender would not otherwise consider; or

it becoming probability that the borrower will enter bankruptcy or financial re-organization; or

the disappearance of an active market for the financial asset due to financial difficulties; or

observable data indicating that there is a measurable decrease in the estimated future cash flows of a group of financial assets after initial recognition,

although the decrease in the estimated future cash flows of individual financial assets included in the group is not identifiable.

For individually significant financial assets, the Group assesses whether objective evidence of impairment exists individually, and it assesses for impairment

of financial assets that are not significant on an individual or collective basis. If there is no objective evidence of impairment exists for financial assets

individually assessed, the Group includes the asset in a group of financial assets with similar credit risk characteristics and collectively assesses them for

impairment. Assets for which the Group recognizes impairment based on an individual assessment or impairment loss is continuously recognized are

not subject to a collective impairment assessment.

The amount of impairment loss is measured as the difference between the asset’s carrying amount and the present value of estimated future cash flows

(excluding future credit loss that are not yet incurred), which is discounted at the financial asset’s original effective interest rate. The amount of loss is

reduced directly from the asset’s carrying value or by using a provision account, and it is recognized in profit or loss.

For loans and receivables or HTM financial assets with the variable interest rate, the current effective interest rate, which is determined under the

contract, is used to measure impairment loss.

Whether collateral inflow is probable or not, the present value of the estimated future cash flows of collateralized financial asset is calculated as the

cash flows, which may arise from collateral inflow, less costs of acquiring and selling collateral.

Future cash flows for a group of financial assets that are collectively assessed for impairment are estimated based on the historical loss experience of

assets having credit risk characteristics, similar to those in the group of financial assets. If historical loss experience is not enough or not existed, similar

corporation’s comparable historical loss experience of a group of financial assets is used. The effects of current conditions that do not have an impact in

Page 95: Woori Bank 2011 Annual Report

FOR THE YEARS ENDED DECEMBER 31, 2011 AND 2010

Woori Bank And SubsidiariesNotes To Consolidated Financial Statements

WOORI BANK

the historical loss experience period are reflected, and the historical loss experience is adjusted based on the current observable data in order to remove

the effects of conditions that currently do not exist but existed in the historical loss experience period.

For a collective assessment for impairment, financial assets are classified based on similar credit risk characteristics (i.e. based on the assessment of credit

risk or grading process, considering asset type, industry, geographical location, collateral type, past-due status, and other relevant elements) indicating

the debtor’s ability to pay all amounts of debt under the contractual terms. These characteristics are relevant to the estimation of future cash flows for

groups of such assets as being indicative of the debtors’ ability to pay all amounts due according to the contractual terms of the assets being evaluated.

When estimating the changes in future cash flows, observable data (i.e. an impairment loss arisen from a pool of assets, an unemployment rate indicating

the loss and its parameter, asset price, product price, or payment status) needs to be consistently reflected. The methodology and assumptions used for

estimating future cash flows are reviewed regularly to reduce the difference between loss estimates and actual loss experience.

When the amount of impairment loss decreases subsequently and the decrease is related to an event occurred after the impairment is recognized (i.e.

an improvement in the debtor’s credit rating), the previously recognized impairment loss is reversed directly from or by adjusting the provision account.

The reversed amount is recognized in profit or loss of current period.

2) AFS financial assets

The Group assesses at the end of each reporting period whether there is objective evidence that the Group’s financial asset (or a group of financial

assets) is impaired. For debt securities, the Group uses the criteria refer to (9)-1) above.

For equity investments classified as AFS financial assets, a significant or prolonged decline in the fair value below the cost is considered objective

evidence of impairment. When the fair value of an AFS financial asset is decreased below its acquisition cost which is considered an objective evidence

of impairment, the cumulative loss, amounting to the difference between the acquisition cost and the current fair value, is removed from other

comprehensive income and recognized in profit or loss as an impairment loss. For AFS equity instruments, impairment losses recognized in profit or

loss on equity instruments are not reversed in profit or loss. Meanwhile, when the fair value of AFS debt instrument increases in a subsequent period

and the evidence is objectively related to an event occurred after recognizing the impairment loss, the impairment loss is reversed and recognized in

profit or loss.

(10) Investment properties

The Group classifies the property held to earn rental or capital gain purpose as investment property. The investment property is measured at its cost

at the initial recognition plus transaction costs arising at acquisition and after recognition, and is presented at cost less accumulated depreciation and

accumulated impairment loss as carrying value.

Subsequent costs are recognized in carrying amount of an asset or as an asset if it is probable that future economic benefits associated with the assets

will flow into the Group and the cost of an asset can be measured reliably. Routine maintenance and repairs are expensed as incurred.

While land is not depreciated, all other investment properties is depreciated based on the respective assets’ estimated useful lives using the straight-line

method. The estimated useful lives, residual values and depreciation method are reviewed at the end of each reporting period, with the effect of any

changes in estimate accounted for on a prospective basis.

(11) Premises and equipment

Premises and equipment are stated at cost less subsequent accumulated depreciation and accumulated impairment losses. The cost of an item of

premises and equipment is directly attributable to their purchase or construction, which includes any costs directly attributable to bringing the asset

FINANCIAL REVIEW

to the location and condition necessary for it to be capable of operating in the manner intended by management. It also includes the initial estimate

of the costs of dismantling and removing the item and restoring the site on which it is located. However, under K-IFRS 1101 ‘First-time Adoption of

International Financial Reporting Standards”, certain premises and equipment such as land and buildings were measured at fair value, which is regarded

as deemed cost, at the date of transition to K-IFRS.

Subsequent costs to replace part of the premises and equipment are recognized in carrying amount of an asset or as an asset if it is probable that the

future economic benefits associated with the assets will flow into the Group and the cost of an asset can be measured reliably. The carrying amount of

the replaced part is eliminated from the books. Routine maintenance and repairs are expensed as incurred.

Premises and equipment are depreciated on a straight-line basis on the estimated economic useful lives as follows:

Classification Useful life

Buildings used for business purpose 40 years

Structures in leased office 5 years

Movable properties for business purposes 5 years

Leased assets Of the same kind or with similar useful lives

The Group reviews the depreciation method, the estimated useful lives and residual values of fixed assets at the end of each annual reporting period.

If expectations differ from previous estimates, the changes are accounted for as a change in an accounting estimate. When the carrying amount of a

fixed asset exceeds the estimated recoverable amount, the carrying amount of such asset is reduced to the recoverable amount.

(12) Intangible assets

1) Goodwill

Any excess of the cost of acquisition over the Group’s share of the net fair value of the identifiable assets acquired, liabilities and contingent liabilities

assumed at the date of acquisition is recognized as goodwill. Such goodwill is classified as intangible assets.

A cash-generating unit to which goodwill has been allocated is tested for impairment annually, or more frequently when there is indication that the unit

may be impaired. If the recoverable amount of the cash-generating unit is less than its carrying amount, the impairment loss is allocated first to reduce

the carrying amount of any goodwill allocated to the unit and then to the other assets of the unit on a pro-rata basis based on the carrying amount of

each asset in the unit. Any impairment loss for goodwill is recognized directly in profit or loss in the consolidated statement of comprehensive income.

An impairment loss recognized for goodwill is not reversed in subsequent periods.

On disposal of the relevant cash-generating unit, the attributable amount of goodwill is included in the determination of the profit or loss on disposal.

2) Development costs, patents and other intangible assets

Intangible assets are stated at the manufacturing cost or acquisition cost plus additional incidental expenses less accumulated amortization and

accumulated impairment losses.

Expenditures incurred in conjunction with development of new products or technology, in which the elements of costs can be individually identified

and future economic benefits are probably expected, are capitalized as development costs under intangible assets. If the Group donates assets, such as

buildings, to the government and is given a right to use or benefit from the assets, the donated assets are recorded as beneficial donated assets under

intangible assets.

Page 97: Woori Bank 2011 Annual Report

FOR THE YEARS ENDED DECEMBER 31, 2011 AND 2010

Woori Bank And SubsidiariesNotes To Consolidated Financial Statements

WOORI BANK

Intangible assets are amortized using the straight-line method over the estimated useful lives, which are five years for development costs, contractual

contact period for the beneficial donated assets, ten years for patents and five years for other intangible assets.

The estimated useful life and amortization method are reviewed at the end of each reporting period. If expectations differ from previous estimates, the

changes are accounted for as a change in an accounting estimate.

Intangible assets, including goodwill and membership, with indefinite useful lives are tested for impairment annually. All other assets are tested for

impairment when there is an objective indication that the carrying amount may not be recoverable, and if the indication exists, the Group estimates

the recoverable amount

(13) Impairment of non-monetary assets

Impairment loss is recognized carrying amount exceeding recoverable amount, recoverable amount is the higher of value in use and net fair value less

costs to sell.

For impairment testing purposes, assets are allocated to each of the Group’s cash-generating units (“CGU”).

Non-monetary assets, except for goodwill impaired, are reviewed in subsequent periods for potential recovery of value and reversal or impairment

previously recognized, at the end of each reporting period.

(14) Lease

A lease is classified as a financial lease, if it transfers substantially all the risks and rewards incidental to ownership with the lessee. Assets held under

finance leases are initially recognized as assets of the Group at their fair value at the inception of the lease or, if lower, at the present value of the

minimum lease payments. The corresponding liability to the lessor is included in the statement of financial position as a finance lease obligation. Lease

obligation deducting related financial cost is recognized as a financial lease liability. Interest factor included in financial cost is reflected in comprehensive

income statements to achieve a constant rate of interest on the remaining balance of the liability.

All other leases are classified as operating leases and are not recognized as an asset in the statement of financial position. Operating lease payments are

recognized as expenses amortized over the lease period using the straight-line method after deducting any incentives from the lessor.

(15) Derivative instruments and hedging activities

Derivatives are initially recognized at fair value at the date the derivative contract is entered into, and they are subsequently remeasured to their fair

value at the end of each reporting period. The resulting gain or loss is recognized in profit or loss immediately unless the derivative is designated and

effective as a hedging instrument.

The Group designates certain hedging instrument to:

hedge of the exposure to changes in fair value of a recognized asset or liability or an unrecognized firm commitment (fair value hedge);

hedge of the exposure to variability in cash flows that is attributable to a particular risk associated with a recognized asset or liability or a highly probable

forecast transaction (cash flow hedge); and

hedge of a net investment in a foreign operation.

At the inception of the hedge relationship, the Group documents the relationship between the hedging instrument and the hedged item, along with its

risk management objectives and its strategy for undertaking various hedge transactions. Furthermore, at the inception of the hedge and on an ongoing

basis, the Company documents whether the hedging instrument is highly effective in offsetting changes in fair values or cash flows of the hedged item.

FINANCIAL REVIEW

a) Fair value hedges

Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recognized in profit or loss immediately, together

with any changes in the fair value of the hedged asset or liability that are attributable to the hedged risk. Hedge accounting is discontinued when the

Company revokes the hedging relationship, when the hedging instrument no longer qualifies for hedge accounting and the fair value adjustment to

the carrying amount of the hedged item is amortized to profit or loss from that date to maturity using the effective interest method.

b) Cash flow hedges

The effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges is recognized in other comprehensive

income. The gain or loss relating to the ineffective portion is recognized immediately in profit or loss. Amounts previously recognized in other

comprehensive income and accumulated in equity are reclassified to profit or loss in the periods when the hedged item is recognized in profit or loss.

Hedge accounting is discontinued when the hedging instrument expires or is sold, or it no longer qualifies for hedge accounting, and any gain or loss

accumulated in equity at that time remains in equity and is recognized when the forecast transaction is ultimately recognized in profit or loss. When a

forecasted transaction is no longer expected to occur, the gain or loss accumulated in equity is recognized immediately in profit or loss.

3) Hedge of a net investment in foreign operations

Hedges of net investments in foreign operations are accounted for similarly to cash flow hedges. Any gain or loss on the hedging instrument relating

to the effective portion of the hedge is recognized in equity while the gain or loss relating to the ineffective portion is recognized immediately in profit

or loss. The cumulated gain and loss in other comprehensive income is reclassified from equity to profit or loss on the disposal or partial disposal of the

foreign operations.

(16) Non-current assets held for sale group

The Group classifies a non-current asset (or disposal group) as held for sale if its carrying amount will be recovered principally through a sale transaction

rather than through continuing use. The Group measures a non-current asset (or disposal group) classified as held for sale at the lower of its carrying

amount and fair value less costs to sell.

(17) Compound financial instruments

The component parts of compound financial instruments issued by the Group are classified separately as financial liabilities and equity in accordance

with the substance of the contractual arrangement. At the date of issue, the fair value of the liability component is estimated using the prevailing market

interest rate for a similar non-convertible instrument. This amount is recorded as a liability on an amortised cost basis using the effective interest method

until extinguished upon conversion or at the instrument’s maturity date. The equity component is determined by deducting the amount of the liability

component from the fair value of the compound instrument as a whole. This is recognised and included in equity and is not subsequently remeasured.

The transaction cost related to the issuance of compound financial instrument is allocated to the liability and equity component proportionately to the

amounts issued.

(18) Provisions

The Group recognizes provisions if it has a present or contractual obligations as a result of a past event, it is probable that an outflow of resources will

be required to settle the obligation, and the amount of the obligation is reliably estimated. Provisions are not recognized for future operating losses.

The Group recognizes provisions related to the unused portion of point rewards earned by credit card customers, payment guarantees and litigations.

WOORI BANK

Where the Group is required to restore a leased property that is used as a branch, to an agreed condition after the contractual term expires, the present

value of expected amounts to be used to dispose, decommission or repair the facilities as an asset retirement obligation.

Where there are a number of similar obligations, the probability that an outflow will be required in settlement is determined by considering the

obligations as a whole. Although the likelihood of outflow for any one item may be small, if it is probable that some outflow of resources will be needed

to settle the obligations as a whole, a provision is recognized.

Provisions are recognized when the Company has a present obligation as a result of a past event, it is probable that the Company will be required to

settle the obligation, and a reliable estimate can be made of the amount of the obligation.

The amount recognized as a provision is the present value of the best estimate of the consideration required to settle the present obligation at the end

of the reporting period. The discount rate used in calculating the present value is the pre-tax discount rate taken into accounts the inherent risks and

time value of the obligation, in the market. The increase in provisions due to the passage of time is recognized as interest expense.

(19) Equity capital

The Company recognizes common stock as equity and redeemable preferred stocks as a liability. Direct expenses related to the issuance of new shares

or options are recognized as a deduction from equity, net of any tax effects.

If the Group reacquires its own equity instruments, those instruments (“treasury shares”) are presented as a deduction from total equity. The gain or

loss on the purchase, sale, issue, or cancellation of treasury shares is not recognized in profit or loss but recognized directly in equity.

(20) Financial guarantee contracts

A financial guarantee contract refers to the contract that requires the issuer to pay the specified amounts to reimburse the holder for a loss because the

specified debtor fails to make payment when due under original or revised contractual terms of debt instruments. The financial guarantee contract is

measured on initial recognition at the fair value, and the fair value is amortized over the financial guarantee contractual term.

After initial recognition, financial guarantee contract is measured at the higher of:

the present value of expected payment amount due to the financial guarantee contract

initially recognized amount of financial guarantee contract less recognized accumulated amortization in accordance with K-IFRS 1018 ‘Revenue’.

(21) Interest income and expense recognition

The Group recognizes interest income and expenses from HTM financial assets measured at amortized cost, loans and receivables, and other financial

liabilities on an accrual basis using the effective interest method.

Effective interest method is the method of calculating the amortized cost of financial assets or liabilities and allocating the interest income or expense

over the relevant period. The effective interest rate reconciles the expected future cash in and out through the expected life of financial instruments or

shorter period if appropriate, and net carrying value of financial assets or liabilities. When calculating the effective interest rate, the group estimates

future cash flows considering all contractual terms of the financial instruments such as prepayment option, except the loss on future credit risk. Also,

effective interest rate calculation reflects commission, points (only responsible for the effective interest rate) that are paid or earned between contracting

parties, transaction costs, and other premiums and discounts.

(22) Dividends

Dividends are recognized as liabilities during in the month it is approved by the shareholder.

(23) Employee benefits

1) Short-term employee benefits

The Group recognizes the undiscounted amount of short-term employee benefits expecting payment in exchange for the services when the employee

renders services. The Group, also, recognizes relevant liabilities and expenses for the accumulating compensated absence when the services that

increase the future paid-leave right are rendered. Expenses and liabilities for the accumulated absence are also recognized in the consideration for

constructive obligation when the Group pays a bonus.

2) Retirement benefits

The Group offers a wide variety of retirement benefit plans and, in general, it raises the amounts computed based on actuarial assumptions through

the payment regarding additional fund in which the insurance company or fiduciary manages.

The Group operates both defined benefit and defined contribution plans. The defined contribution plan is the retirement benefit plans that pay the

fixed amount of bonus to other fund organizations. The Group does not have any legal or constructive obligations to make further payment even if it

does not pay all employee benefits relating to employee service rendered to the Group in the current and prior periods.

For defined benefit plans, the liability recognized in the statement of financial position is the present value of the current defined benefit obligation at

the date of the statement of financial position, less the fair value of plan assets, adjusted for unrecognized past service cost.

The defined benefit obligation is calculated on an annual basis by independent actuaries according to the projected unit credit method. The present

value of defined benefit obligations is expressed in a currency in which retirement benefits will be paid and is calculated by discounting expected future

cash outflows with the interest rate of high quality corporate bonds which maturity is similar to the payment date of retirement benefit obligations.

Actuarial gains and losses arising from the difference between changes in actuarial assumptions and what has actually occurred are recognized in profit

or loss in the period in which they occur.

Past service cost is reflected immediately in profit or loss. However, past service cost is recognized as an expense on a straight-line basis over the vesting

period when changes in retirement pension plan continues to require employees to remain on work duties during the vesting period.

Being connected to defined contribution plans, the Group mandatorily, contractually, or voluntarily pays contributions to pension insurance plans, which

are managed publicly or privately. The Group has no payment obligations after contributions are paid. Contributions are recognized as employee benefit

expense at a due date for payment. Prepaid contributions are recognized a decrease in future payment due to the excessive contributions or available

refund as assets.

3) Termination benefits

Termination benefits are paid when employment is terminated by the Group before the normal retirement date or an employee accepts voluntary

retirement in exchange for benefits. The Group recognizes termination benefits when employment is terminated based on detailed formal plans or

voluntary retirement is encouraged, providing termination benefits. Termination benefits are discounted at present value when they are due more than

12 months after the reporting date.

4) Profit-sharing and bonus plan

The Group recognizes appropriate provisions and expenses considering profits related shareholders of the Group after adjusting a specific sum of

amounts. The Group recognizes contractual obligations and obligations as a result of a past practice as provisions.

(24) Income tax expense

Income tax comprises current tax and deferred tax. Income tax is recognized in profit or loss except to the extent that it relates to items recognized in

other comprehensive income or directly in equity.

Current tax expenses are calculated based on the basis of tax laws that have been enacted by the reporting date or substantively enacted in the

countries where the Group operates and generates taxable income.

Deferred tax is recognized on temporary differences between the carrying amounts of assets and liabilities in the financial statements and the

corresponding tax bases used in the computation of taxable profit. However, the Company does not recognize deferred tax arising on the initial

recognition of an asset or a liability in a transaction that is not a business combination and that, at the time of the transaction, affects neither accounting

profit nor taxable profit. Deferred taxes are determined using tax rates and laws that have been enacted by the reporting date —the date when the

relevant deferred tax assets are realized and the deferred tax liabilities are settled— or substantially enacted.

Deferred income tax assets are recognized if future taxable profits are probable so that the temporary differences can be used.

Deferred income tax liabilities are provided on temporary differences arising on investments in subsidiaries and associates, except where the timing of

the reversal of the temporary difference is controlled by the Group and it is probable that the temporary difference will not reverse in the foreseeable

future.

Deferred income tax assets and liabilities are offset when there is a legally enforceable right to offset current tax assets against current tax liabilities and

when the deferred income taxes assets and liabilities relate to income taxes levied by the same taxation authority on either the taxable entity or different

taxable entities where there is an intention either to settle the balances on a net basis or to realize the asset and settle the liability simultaneously.

(25) Origination fees and costs

The commission, which is part of the effective interest rate of loans, is accounted for deferred origination fees. Incremental cost related to the acquisition

or disposal is accounted for deferred origination costs, and it is amortized on the effective interest method and included in interest revenues on loans.

(26) Loan sales

When the Group disposes of loans based on valuations performed by a third party independent specialist (institution) using a reasonable and rational

method, the difference between the book value and the selling price is recognized as disposal gains and losses.

(27) Earnings per share (“EPS”)

Basic earnings per share is calculated by dividing net income from the statement of comprehensive income by the number of outstanding common

shares, and diluted EPS is calculated by adjusting earnings and number of shares for the effects of all dilutive potential common shares.

(28) Accounting developments

The Group has not applied the following new and revised K-IFRS that have been issued but are not yet effective:

Amendments to K-IFRS 1107 ‘Disclosures – Transfers of Financial Assets’

The amendments to K-IFRS 1107 increase the disclosure requirements for transactions involving transfers of financial assets. These amendments are

intended to provide greater transparency around risk exposures when a financial asset is transferred but the transferor retains some level of continuing

exposure in the asset. It will be applied for annual periods beginning on or after July 1, 2011.

FINANCIAL REVIEW

Amendments to K-IFRS 1012 ‘Deferred Tax – Recovery of Underlying Assets’

Under the amendments, investment properties that are measured using the fair value model in accordance with K-IFRS 1040 Investment Property and

property and equipment that are measured using revaluation model in accordance with K-IFRS 1016 Property, plant and equipment are presumed to

be recovered through sale for the purposes of measuring deferred taxes, unless the presumption is rebutted in certain circumstances. It will be applied

for annual periods beginning on or after January 1, 2011.

Amendments to K-IFRS 1019 – ‘Employee Benefits’

The amendments to K-IFRS 1019 change the accounting for defined benefit plans and termination benefits. The most significant change relates to the

accounting for changes in defined benefit obligations and plan assets when they occur, and hence eliminate the ‘corridor approach’ permitted under

the previous version of K-IFRS 1019 and accelerate the recognition of past service costs. The amendments to K-IFRS 1019 are effective for annual

periods beginning on or after January 1, 2013.

Legislation of K-IFRS 1113 ‘Fair Value Measurement’

K-IFRS 1113 establishes a single source of guidance for fair value measurements and disclosures about fair value measurements. K-IFRS 1113 is effective

for annual periods beginning on or after January 1, 2013, with earlier application permitted.

The Group anticipates that the amendments listed above may not have significant impact on the Group’s consolidated financial statements.

(29) Others

1) Reclassification of gains (losses) on beneficiary certificates

For the year ended December 31, 2010 and the six months ended June 30, 2011, the Bank had classified its dividends from beneficiary certificates and

gains (losses) on disposal of beneficiary certificates as other interest income on beneficiary certificates. Subsequent to the period, the Bank changed

its classification for the dividends to dividend income on beneficiary certificates and gains (losses) on disposal of beneficiary certificates to and gains

(losses) of disposal of AFS, respectively.

The effects of change for the years ended December 31, 2010 and for the six months ended June 30, 2011 are as follows (Korean Won in millions):

2011 2010

Three months ended March 31

Six months ended June 30

Three months ended March 31

Six months ended June 30

Net interest income \ (28,759) \ (85,151) \ (35,635) \ (91,232)

Dividend income 2,139 11,352 4,484 19,299

Gain (loss) on AFS financial assets

26,620 73,79931,151 71,933

As a result of the reclassification as discussed above, the Bank retroactively adjusted the financial statements for the prior period and such reclassification

did not have an effect on net assets and net income of the Bank.

2) Impairment loss on Kumho Industrial Co., Ltd.

According to the previous GAAP (“K-GAAP”), Statements of Korean Accounting Standards No. 2 ‘Interim Financial Reporting’, the impairment loss on

financial assets should be recognized on a cumulative basis when the fair value of the investment is decreased more than 30 percent of the acquisition

cost. During the 2010 interim period, \33,083 million of impairment loss on the investment in Kumho Industrial Co., Ltd. was recognized due to

Page 103: Woori Bank 2011 Annual Report

FOR THE YEARS ENDED DECEMBER 31, 2011 AND 2010

Woori Bank And SubsidiariesNotes To Consolidated Financial Statements

WOORI BANK

the decrease in its fair value more than 30 percent of the acquisition cost. The impairment loss recognized during the interim period was reversed for

the year ended December 31, 2010 due to the increase in the fair value of Kumho Industrial Co., Ltd. in a subsequent period in accordance with the

previous GAAP.

Based on K-IFRS adopted from the fiscal year beginning on January 1, 2010, the impairment losses on AFS financial assets recognized during the interim

period cannot be reassessed on a cumulative basis. As such, the impairment loss on the financial assets recognized during the interim period due to

the decrease in fair value of the AFS financial assets should not be reversed through profit or loss when the fair value of the AFS financial assets is

increased subsequently. The impairment losses amounting to any increase in the fair value of the AFS financial assets in a subsequent period should be

recognized as other comprehensive income.

3) Reclassification of due from banks in foreign currencies

The Bank loaned to Woori Bank China (Limited) during January 2011 and recognized the loan as due from banks in foreign currencies as of March 31,

2011 and June 30, 2011, respectively. As of September 31, 2011, the Bank reclassifies the loans from to inter-bank loans in foreign currencies.

The effects of change as of March 31 and June 30, 2011 are as follows (Korean Won in millions):

2011

As of March 31 As of June 30

Decrease in due from banks \ (22,144) \ (86,248)

Increase in inter-bank loans 22,144 86,248

As a result of reclassification, the Bank retroactively adjusted the financial statements for the prior period and such reclassification did not have an effect

on net assets and net income of the Bank.

4) Change in the recognition of gains (losses) on transactions of derivatives

As for the application of K-GAAP, the Bank recorded gains (losses) on transactions of derivatives that for the year ended December 31, 2010, the Bank

recognized gains (losses) on transactions of derivatives such as interest swap, currency swap and commodity swap based on the gross amount of the

assets (liabilities) and the settlement amount, respectively. The Bank changed its recognition of gains (losses) on such transactions based on the net of

the assets (liabilities) and settlement amount.

The effects of change for the years ended December 31, 2010 under K-GAAP are as follows (Korean Won in millions):

2010

Three months ended March 31

Six months ended June 30

Nine months ended September 30

The year ended December 31

Decrease in losses on transactions of derivatives

(71,321) (120,273) (208,800) (262,991)

As a result of the changes as discussed above, such changes did not have an effect on net assets and net income of the Bank for the year ended

December 31, 2010.

Also, as for the application of credit default swap under K-GAAP, the Bank recorded gains (losses) on transactions of derivatives with total amount of

As a result of the changes as discussed above, such changes did not have an effect on net assets and net income of the Bank for the three months

ended March 31, 2010 and six months ended June 30, 2010, respectively.

3. SIGNIFICANT ACCOUNTING ESTIMATES AND ASSUMPTIONS

The significant accounting estimates and assumptions are continually evaluated and are based on historical experience and various factors including

expectations of future events that are considered to be reasonable. Actual results can differ from those estimates based on such definitions. The

following are the accounting estimates and assumptions that have a significant risk of causing changes to the carrying amounts of assets and liabilities

within the next accounting period.

(1) Impairment of goodwill

The Group performs impairment test of goodwill annually or more frequently when there is indication that a CGU may be impaired. Determining

whether goodwill is impaired requires an estimation of the value in use of the CGU to which goodwill has been allocated. The value in use calculation

requires the Group’s management to estimate the future cash flows expected to arise from the CGU and a suitable discount rate in order to calculate

present value.

(2) Fair value of financial instruments

The fair value of financial instruments that are not traded in an active market is determined by using valuation techniques. The Group uses its judgment

to select a variety of valuation techniques and make assumptions based on market conditions existing at the end of each reporting period.

(3) Impairment loss on financial assets

The Company individually recognizes an impairment loss on financial assets by assessing the occurrence of loss events or it assesses impairment for a

group of financial assets with similar credit risk characteristics. Impairment loss for financial assets is the difference between such assets’ carrying value

and the present value of estimated recoverable cash flows. The estimation of future cash flows requires management judgment.

4. RISK MANAGEMENT

The Group’s operating activity is exposed to various financial risks; hence, the Group is required to analyze and assess the level of complex risks,

determine the level of risks to be accepted, or to manage the risks.

FOR THE YEARS ENDED DECEMBER 31, 2011 AND 2010

WOORI BANK

The Group’s risk management procedure is set for improvement in the quality of assets held and investments by making a decision about how to avoid

or mitigate risks through the identification of the cause of the potential risk and its scope.

The Group takes the approach to minimize the risk and maximize the profit by managing the risks acceptable to the Group and eliminating the excessive

risks of financial instruments. For this, the following procedures are performed: risk recognition, measurement and assessment, control, and monitoring

and reporting.

The risk is managed by the risk management department based on the Group’s policy. The Risk Management Committee of the Group makes the

decision on the risk strategy such as allocation of risk assets and limit settlement.

(1) Credit risk

Credit risk represents the possibility of financial losses incurred when the counterparty fails to fulfill its contractual obligations. The goal of credit risk

management is to maintain the credit risk exposure to a permissible degree and to optimize the rate of return considering such credit risk.

1) Credit risk management

The Group considers the probability of failure in performing the obligation of its counterparties, credit exposure to the counterparty and the related

default risk and the rate of default loss. The Group uses the credit rating model to assess the possibility of counterparty’s default risk; and when

assessing the obligor’s credit grade, the Group utilizes credit grades derived using statistical methods.

2) Credit line management

In order to manage credit risk limit, the Group establishes the appropriate credit line per obligor, company or industry and monitors obligors’ credit line,

total exposures and loan portfolios when approving the loan.

3) Credit risk mitigation

The Group mitigates credit risk resulting from the obligor’s credit condition by using financial and physical collateral, guarantees, netting agreements

and credit derivatives. The Group has adopted the entrapment method acknowledged by BASEL II standards to mitigate its credit risk. Credit risk

mitigation is reflected in qualifying financial collateral, trade receivables, guarantees, residential and commercial real estate and other collaterals. The

Group regularly performs a revaluation of collateral reflecting such credit risk mitigation.

4) Maximum exposure to credit risk

The maximum exposures of financial instruments, excluding equity securities, to credit risk are as follows (Korean Won in millions):

(2) Market risk

Market risk is the possible risk of loss arising from trading activities in the volatility of market factors such as interest rates, stock prices, and foreign

exchange rates. Market risk occurs as a result of changes in the interest rates and foreign exchange rates for financial instruments that are not yet

settled, and all contracts are exposed to a certain level of volatility according to the interest rates, credit spreads, foreign exchange rates and the price

of equity securities.

1) Market risk management

For trading activities, the Group avoids, bears or mitigates risks by identifying the underlying source of risks, measuring parameters and evaluating their

appropriateness.

2) Market risk measurement

The Group uses both standard-based and internal model-based approach to measure market risk. A standard risk measurement model is used to

calculate individual market risk of owned capital while internal risk measurement model is used to calculate general capital market risk and it is used

to measure internal risk management measure. The Risk Management Committee allocates owned capital to market risk. The Risk Management

department measures the Value at Risk (“VaR”, maximum losses) limit by department and risk factor and loss limit on a daily basis and reports regularly

to the Risk Management committee.

3) Risk Control

At the beginning of each year, the Risk Management Committee establishes the VaR limit, loss limit and risk capital limit for its management purposes.

Limit by investment desk/dealer is independently managed to the extent of the limit given to each departments of the Group and the limit by investment

and loss cut is managed by risk management personnel with the department.

4) Sensitivity analysis of market risk

The Group performs sensitivity analysis for both trading and non-trading activities. For trading activities, the Group uses a VaR model which uses

certain assumptions of possible fluctuations in market condition and, by conducting simulations of gains and losses, under which the model estimates

the maximum losses that may occur. A VaR model predicts based on statistics of possible losses on the portfolio at a certain period currently or in the

future. It indicates the maximum expected loss with at least 99% credibility. In short, there exists a one percent possibility that the actual loss might

exceed the predicted loss generated from the VaR's calculation. The actual results are periodically monitored to examine the validity of the assumptions

and variables and factors that are used in VaR's calculations. However, this approach cannot prevent the loss when the market fluctuation exceeds

expectation.

For non-trading activities, interest rate Earning at Risk (“EaR”) and interest rate VaR, which is based on the simulations of the Net Interest Income (“NII”)

and Net Present Value (“NPV”), are calculated for the Bank and the risk for all other subsidiaries is measured and managed by the interest rate VaR

calculations based on a ‘Gap’ in interest rate per Bank for International Settlements (“BIS”) Framework. NII is a profit based indicator for displaying the

profit changes in short term due to the short term interest change. It will be estimated as subtracting the interest expenses of liabilities from the interest

income of the assets. NPV is an indicator for displaying the risk in economical view according to the unfavorable changes related to the interest rate. It

will be estimated as subtracting the present value of liabilities from the present value of the asset. EaR shows the maximum profit-loss amount, which

indicates the maximum deduction amount caused by the unfavorable changes related to the interest rate of certain period of time. Interest rate VaR

shows the potential maximum loss generated by the unfavorable changes during certain period of present or future.

a) Trading activities

The minimum, maximum and average VaR for the year ended December 31, 2011 and 2010, respectively, and the VaR as of December 31, 2011 and

(3) Liquidity risk

Liquidity risk refers to the risk that the Group may encounter difficulties in meeting obligations from its financial liabilities.

1) Liquidity risk management

Liquidity risk management is to prevent potential cash shortage as a result of mismatching the use of funds (assets) and sources of funds (liabilities) or

unexpected cash outflows.

Assets and liabilities are grouped by account under Asset Liability Management (“ALM”) in accordance with the characteristics of the account. The

Group manages liquidity risk by identifying maturity gap and such gap ratio through various cash flows analysis (i.e. based on remaining maturity and

contract period, etc.); while maintaining the gap ratio at or below the target limit.

2) Maturity analysis of non-derivative financial liabilities

a) The Group’s maturity analysis of non-derivative financial liabilities, cash flows of principals and interests, by remaining

contractual maturities are as follows (Unit: Korean Won in millions):

Page 123: Woori Bank 2011 Annual Report

FOR THE YEARS ENDED DECEMBER 31, 2011 AND 2010

Woori Bank And SubsidiariesNotes To Consolidated Financial Statements

WOORI BANK

The Group has been running the operational risk management system under Basel II . The Group developed advanced measurement approached

to quantify required capital for operational risk. This system is used for reinforcement in foreign competitions, reducing the amount of risk capitals,

managing the risk, and precaution for any unexpected occasions. This system has been tested by the independent third party, and this system approved

by the Financial Supervisory.

2) Operational risk measurement

To quantify required capital for operational risk, the Group applies advanced measurement approach using of internal loss data, business environment

and internal control factors and scenario analysis. For the risk management over subsidiaries of the Group, the Group uses the basic indicator approach.

(5) Capital management

The Group follows the capital adequacy standard suggested by the Financial Supervisory. This standard is based on Basel II from 2004, which has been

adopted in Korea since 2008. In accordance with banking regulations, the Group is required to maintain a minimum 8% of capital adequacy ratio with

high capital risk.

According to the Banking supervision by laws enforcement, the entity's capital can be clarified into two kinds.

– Tier 1 capital (Basic capital): Basic capital consists of the capital, capital surplus, retained earnings, the entity's non-controlling interest (hybrid security

included), exchange differences in other accumulated comprehensive incomes.

– Tier 2 capital (Supplement capital): Supplement capital includes revaluation reserves, gains on valuation of available for sale securities, 45% of share

of other comprehensive income on investment in associates, 70% of the existing revaluation gain of fixed assets of the retained earnings, subordinated

term debt more than 5 years, the provision for credit losses under banking supervision regulations.

Risk Weighted Assets is the Group’s assets weighted according to credit risk; errors caused by internal process problems, external occasions and danger

of the change in market. The entity calculates risk weighted assets to obey the banking supervisory's detailed enforcement and BIS percentage to

predict the equity capital by adding the basic and complementary capital total.

The Group makes measures to cope with certain level of loss caused by accumulating the equity capital that is exposed to the risk. The Group is testing

and using not only the BIS percentage, which is the minimum regulation standard, but also it is using internal standards. An evaluation on capital

adequacy is performed to calculate the gap between available capital and economic capital. In addition, analysis on emergent incidents and additional

capital requirements are added and applied. The capital adequacy is evaluated for both supervisory and internal management purpose in accordance

with the comparison of unexpected loss and the available capital. If the test result from internal capital adequacy shows lack of available capital, the

Group is committed to expanding the equity capital and reinforcement of the risk management.

(*1) Derivatives classified FVTPL are included in derivative assets and liabilities.

Financial assets and liabilities at FVTPL, AFS financial assets, held-for-trading financial assets and liabilities and derivative assets and liabilities are

recognized at fair value. Fair value is the amount for which an asset could be exchanged, or a liability settled, between knowledgeable, willing parties

in an arm’s length transaction.

Financial instruments are measured at fair value using a quoted market price in active markets. If there is no active market for a financial instrument,

the Group establishes the fair value using valuation techniques. Fair value measurement methods for each type of financial instruments are as follows:

Fair value measurement technique

Financial assets and liabilities at FVTPLFinancial assets and liabilities at FVTPL are measured at fair value using a price quoted by a third party, such as a pricing service or broker, or using valuation techniques.

Held-for-trading financial assets and liabilities and AFS financial assets

Held-for-trading financial assets and liabilities and AFS financial assets are measured at fair value using a quoted market price in an active market. If a quoted market price is not available, they are measured by using a price quoted by a third party, such as a pricing service or broker, or using valuation techniques.

Derivative assets and liabilities Derivatives are measured at fair value using a quoted market price in an active market. If a quoted market price is not available, they are measured at fair value using valuation techniques.

Loans and receivables Loans and receivables are measured by discounting expected future cash flows at a market interest rate of other loans with similar condition.

HTM financial assets HTM financial assets are measured by using a price quoted by a third party, such as a pricing service or broker.

Deposits due to customers and bor-rowings

Deposits due to customers and borrowings are measured at fair value using discounting expected future cash flows at the interest rate of bond issued by the Group. However, if the carrying value is not signifi-cantly different from the fair value, it assumes that the carrying value is equal to the fair value.

Debentures The fair value of issued bond shall be measured at the present value of cash flows using the swap interest rates. For some financial instruments, the fair value estimated by specialists, the third party, can be used.

into financial asset at FVTPL, AFS financial assets or loans and receivables under K-IFRS.

B. Financial assets at FVTPL

Cash and cash equivalents or AFS securities under K-GAAP are designated as or transferred to financial assets at FVTPL under K-IFRS. Fair value changes

due to credit risk adjustment and others result in a change in net assets.

Page 201: Woori Bank 2011 Annual Report

FOR THE YEARS ENDED DECEMBER 31, 2011 AND 2010

Woori Bank And SubsidiariesNotes To Consolidated Financial Statements

WOORI BANK

AFS securities under K-GAAP are designated as or reclassified to financial assets at FVTPL. In addition, different accounting methods on reversal of

impairment loss for AFS securities result in a decrease in net assets.

D. HTM financial assets

Application of the effective interest method to HTM securities measured at amortized cost results in a decrease in net assets.

E. Loans and receivables

Bank deposits included in cash and cash equivalents under K-GAAP are transferred to loans and receivables under K-IFRS and prepaid rental deposits

under K-GAAP are reclassified into other assets under K-IFRS. Also, changes in net assets are attributable to the different accounting treatments in

deferred loan fees and amortization method using the effective interest rate, combined with different set-out scope of provision for receivables and its

calculation methodology.

F. Investment in associates

Some securities accounted for under the equity method under K-GAAP are reclassified as AFS securities under K-IFRS. Accordingly, adjustments

regarding equity in earnings have changed the net asset amount.

G. Investment properties

Non-operating fixed assets included in property, plant and equipment under K-GAAP segregated and transferred to investment properties.

H. Premises and equipment

Non-operating fixed assets and assets to be disposed that have been recorded in other assets under K-GAAP are reclassified into investment properties

and assets held for sale, respectively, under K-IFRS. Also, acquisition cost adjustment due to revaluation of fixed assets and establishment of provision

for asset retirement result in change in net asset value.

I. Intangible assets

Among the deposits recognized under K-GAAP, membership deposit with the expected future economic benefits is reclassified as intangible asset under

K-IFRS.

J. Other assets

Prepaid rental expense in rental deposits under K-GAAP is transferred to other assets.

K. Deferred tax assets

Changes in deferral amount arising from fair value evaluation of financial asset/liability and different methodology of impairment assessment, along

with different depreciation expense and denial of provision liability have changed the amount of deferred tax asset under K-IFRS.

L. Derivatives assets

Page 202: Woori Bank 2011 Annual Report

FINANCIAL REVIEW

Certain derivative instruments applicable to hedge accounting under K-GAAP are reclassified as a separate derivative asset (hedge) under K-IFRS and

the amount of net asset was changed by the net effects of fair value adjustments.

M. Assets held for sale

Properties to be disposed under K-GAAP are reclassified into assets held for sale under K-IFRS.

N. Financial liabilities at FVTPL

Some portion of corporate bonds are designated as and reclassified to financial liabilities at FVTPL. Fair value changes due to credit risk adjustment and

others result in a change in net assets.

O. Deposits

Changes in net assets are attributable to the application of the effective interest method in the calculation of interest expense for CD and equity-linked

securities (ELS), previously recognized as interest payable under K-GAAP, and net book value adjustments.

P. Borrowings

Changes in net assets are attributable to the application of the effective interest rate method in the calculation of interest expense for borrowings and

net book value adjustments.

Q. Debentures

Some debentures are designated as financial liabilities at FVTPL. Hybrid securities meeting the definition of capital, in substance, are reclassified as non-

controlling equity under K-IFRS. Changes in net assets are attributable to the difference in fair value measurement of the corporate bonds subject to

the hedge accounting and difference in amortization cost based on the effective interest rate method.

R. Other provision

Difference in calculation methodology of provision for unused commitment, guarantee and other liabilities results in changes in net assets.

S. Other financial liabilities

A substantial portion of unearned rental income recorded in rental deposits within other financial liabilities under K-GAAP are transferred to other

liabilities under K-IFRS. Changes in net assets are attributable to the changes in the carrying amount of accrued liabilities in relation to interest payables

on CD and ELS and the different calculation methodology for accrued vacation benefits.

T. Other liabilities

A substantial portion of unearned rental income recorded in rental deposits within other financial liabilities under K-GAAP are transferred to other

liabilities under K-IFRS. Changes in net assets are attributable to the separation of unearned revenue related to certain portions of provision for credit

card point rewards and the amount of unearned revenue reclassified to deferred loan fees.

U. Deferred tax liabilities

Page 203: Woori Bank 2011 Annual Report

FOR THE YEARS ENDED DECEMBER 31, 2011 AND 2010

Woori Bank And SubsidiariesNotes To Consolidated Financial Statements

WOORI BANK

Changes in deferral amounts of asset and liability, derived by fair value measurement and impairment assessment, changes in depreciation expenses

and denial of provision liabilities result in an increase in deferred tax liabilities.

V. Derivatives liabilities

Certain derivative instruments applicable to hedge accounting under K-GAAP are reclassified as a separate derivative liability (hedge) under K-IFRS and

the amount of net asset was changed by the net effects of fair value adjustments.

W. Capital stock

Changes in capital were incurred due to fluctuation of exchange rate, applicable when translating capital of overseas subsidiaries.

X. Hybrid securities and other capital

The Group reclassified hybrid securities that meet the definition of capital in economic substance as a capital from liabilities. Gains of losses on fair value

measurement in relation to reclassification of AFS securities are transferred to retained earnings. In addition, net asset balance has been adjusted due

to the deferred income tax adjustment and others.

Y. Capital surplus

Certain amounts of capital surplus related to the equity method securities under K-GAAP are transferred to retained earnings using the deemed cost

method.

Z. Retained earnings

Reclassification of AFS securities and adoption of deemed cost to securities using the equity method changed the amount of retained earnings. In

addition, difference in fair value evaluation provisions, accrued interest expense and depreciation expense, along with revaluation of fixed assets and

profit/loss adjustment in association with financial guarantee contracts caused a change in retained earnings.

Transition effects on operational results

A. Interest income

The amount of interest income changes due to the difference in amortized deferred fee of loans and receivables using the effective rate method,

interest income recognized for impaired loans, and adjustments to accrued interest income for impaired loans. In addition, the change of time value

in account receivables associated with financial guarantee, transfer of interest income related to credit card points to unearned revenue, recognition

of present value discounts amounting to the substantial portion of prepaid rental expenses and its amortization cost using the effective rate method

result in changes in interest income.

B. Interest expense

Reclassification of hybrid securities from corporate bonds under K-GAAP to capital account under K-IFRS results in a transfer of interest expense to

dividend expense and a change in retained earnings. In addition, difference in amortized interest expenses with regards to financial liabilities and

exchange rate applied when translating interest expense of foreign currency denominated financial liabilities results in a change in interest expense.

Page 204: Woori Bank 2011 Annual Report

FINANCIAL REVIEW

C. Net fees and commissions income

Fees and commissions income changes due to the adjusted deferred loan costs (fees) related to loans and receivables and the offset amount with

financial guarantee assets when fees and commissions related to financial guarantee contracts are received. Fees and commission expense changes due

to the adjusted deferred loan costs (fees) related to loans and receivables.

D. Dividend income

Certain equity method securities are reclassified into AFS securities and dividend income from these reclassified AFS securities has been recognized

accordingly.

E. Gain (loss) on financial assets at FVTPL

Different valuation amounts using fair value measurement derived by credit risk adjustments to derivative instruments result in changes in profit/loss

on financial assets

F. Gain (loss) on AFS financial assets

Profit or loss on AFS securities has been changed, responding to the account reclassification.

G. Impairment losses for loans, other receivables, guarantees and unused commitments on credit loss

Impairment losses for loans, other receivables, guarantees and unused commitments are caused by differences in the scope and calculation methodology

of provision for loans and receivables, and differences in the calculation of unused commitment and payment guarantee.

H. Other operating income (expense)

Changes in other operating income or expense are attributable to gains or losses on foreign currency transactions due to the different exchange

rates applied at the transaction date, changes in depreciation expenses due to the changed net book value of fixed assets and changes in selling and

administrative expenses contributed by changed vacation benefits and defined benefit retirement expense. Moreover, differences in rental income and

expense have occurred in regards with prepaid rental expense and unearned rental income, respectively.

I. Gain (loss) on equity method investments

The net effect of gain or loss on valuation of equity method under K-GAAP has been reversed as certain securities accounted for under the equity

method are reclassified to AFS securities under K-IFRS.

J. Income tax expense

Changes in income tax expense are attributable to the changes in deferred tax assets and liabilities.

K. Other comprehensive income (loss)

Reclassified AFS securities under K-IFRS made a change in the amount of other comprehensive income.
