Increase of allowances for loan losses

We have increased our allowances for loan losses to protect our loan portfolio from possible impacts due to the pandemic that might materialize in the future, taking into account macroeconomic prospects both in Chile and Colombia as well as sector, product and client-specific aspects

As a result, our cost of credit for October 2020 was Ch$234 billion:

o Chile: Ch$170 billion, including

▪ Ch$86 billion for Corporate and SME clients of sectors most impacted by the pandemic

▪ Ch$33 billion in additional provisions for our retail portfolio

▪ Ch$17 billion for the deductible of FOGAPE-COVID loans

o Colombia: Ch$64 billion, of which Ch$44 billion are additional provisions

Considering these provisions, net income for October 2020 was negative Ch$156 billion
