Fiber to the Home (FTTH)

“Home Run”

Separate fiber to each home from Head End or Central Office

Pros:• Ultimate performance• Highest flexibility• Minimal interoperability and upgradeability issues

Cons:• Extremely high cost• Incremental build-out expensive as well

“Active Star”

Fiber runs from Head End to remote hubs with switching equipment

Pros:• High performance• Diversity of services

Cons:• High equipment costs• Reliability issues: need for power at every remote• Aesthetics, real estate for remotes

Passive Optical Network (“PON”)

Single fiber runs from Head End to hubs with passive optical splitters

Pros:• Lowest life-cycle costs• Simplest design, minimal need for field electronics• Highest reliability

Cons:•Requires simultaneous upgrade of remotes and Head End• Shared resource: bottlenecks upstream, signal compatibility

Gigabit Ethernet (“GigE”)

Giga Bit Ethernet is a technology which uses “distributed” routers allowing direct 110 Base T or higher connections to the home.

Pros: • Simple Interface•High Data Rate

Cons:• Shared local connection•Increases complexity and management

What is Municipal Broadband?

• Optical fiber network owned by municipality (Town / Utility)

• Fiber connectivity to homes and commercial properties: 100 Mbps service, Fiber to the Home (FTTH)

• Integration of school, fire, police, public safety, healthcare

• Open access network allowing any service provider/ISP

• Municipality provides “bit” backbone only; service provider owns end-users

Incumbent network provider “Owns” all of the local customers

High borrowing cost of capital Unbundling of broadband poses business risk to existing services Significant cuts in budget Politically complex

Local CATV presence “Owns” the CATV customer

Very bad cash position Need to upgrade cable plants to support two-way broadband in outlying areas

Some broadband in larger cities and towns Some backbone infrastructure

Limited to no financial capability Serious negative cash flow

MunicipalNetwork

Capable of raising financing at low cost of capital Capable of local and targeted deployment No local regulatory problems

No network operational skills, but can be easily outsourced No infrastructure support capabilities, but can be easily outsourced

Financing “Public Works” Project

• Treat municipal broadband project as Public Works; like building town roads or sewers

• Local municipality finances, builds, owns and operates broadband infrastructure

• Financing: municipal revenue bonds (tax-exempt)

• Feasibility test: “Revenues sufficient to cover debt service and direct expenses?”

• Could be partially underwritten by anchor tenants (local businesses and other institutions/coops)

Competition

• Merton is s service integrator: not in highly competitive business of construction, optical technology or consulting

• Focused on niche market with high demand: public sector

• Targeted towns below radar of RBOCs and Cable for fiber broadband; private sector weakened financially

• Only one other known service integrator providing similar functions: DynamicCity out of Provo, UT

Competitive Factors

• Operational, technical and financial experience

• Operations support capability

• Credibility in industry and in Washington

Risks

Risk Explanation Mitigation

Market Risk Towns not prepared to take on MBN projects

Market is large and there is known demand

Timeline / Sales Cycle Risk Time to revenues on any given project is high

Diversity of town portfolio; Co-Op approach reduces lead time

Regulatory / Political Risk State or Federal regulation, or ILEC supportive laws might prohibit MBN

Below radar of ILECs; Merton lobbying both Federal and state legislators

Vendor Risk Long-term viability of vendors

Careful selection of vendors; due-diligence

Town Financing Risk Towns may not be able to raise required capital

Track record of infrastructure projects funded by municipal bonds

Beyond Starting Point

• Starting Point is one “if” scenario: Only homes with second telephone lines moved to Municipal Broadband Network

• Higher home penetration likely

• Commercial / public utility provide incremental revenues

• All other revenues are costless:

– Higher fee for 100 Mbps services

– Value added services: video, telephone, HD TV

Financing “Public Works” Project

• Treat municipal broadband project as Public Works; mission driven, not profit driven

• Local municipality finances, builds, owns and operates broadband infrastructure

• Financing: municipal bonds (tax-exempt/taxable)

• Feasibility test: “Revenues sufficient to cover debt service and direct expenses?”

• Could be partially underwritten by anchor tenants (local businesses and other institutions/coops)

Municipal Project

• Town invokes State Constitutional Authority to initiate public works project

• Local municipality finances, builds, owns and operates broadband infrastructure

• Feasibility test: “Revenues sufficient to cover debt service and direct expenses?”

• Public works project: mission driven, not profit driven

• Partially underwritten by anchor tenants (local businesses)

Terrence P. McGarty, Lisbon February 13, 2003

Alternative Approach

• Use optimal combination of alternatives to achieve highest quality, lowest lead-time, most cost-effective establishment of local broadband infrastructure and services

• Example

– Town finances 80% of network installation; sells 20% shares to interested parties (co-ops, businesses)

– Town issues municipal bonds to finance project

– Town builds, owns and operates network; sells unbundled network access to ISPs and IAPs

– ISPs, IAPs provide voice, data and video services

Financing Options – Municipal Bonds

• Revenue Bonds– Tax-exempt municipal debt secured by revenues from projects

• General Obligation Bonds– Tax-exempt municipal debt secured by tax assessments and project

earnings– Voter approval required

• Assessment Bonds– Municipal debt secured by special tax assessments on property

forming collateral on bonds• Mello-Roos Bonds

– Municipal debt secured by tailored special tax assessments on assets forming collateral on bonds; greater flexibility

• Certificates of Participation (COPs)– Revenue COPs or Lease COPs (secured by district’s general fund)– No votes, property assessment required; greatest flexibility

Competitive Analysis

• Some 50 municipal fiber installations in the U.S. and about 200 municipal broadband projects overall

– Technology and operations is commodity

– Financing, politics and regulatory issues are key barriers

• Most existing projects financed by internal cash of municipalities, cumbersome bank loans and some bonds

• Initial financing + full service support (political, legal, finance, technology, operations) is unique concept and key to successful implementation (Merton)
