b) Structural Interest Rate Risk<br />
This risk mainly results from business activity (commercial loans vs. deposits) and is caused by the effects of changes in interest rates<br />
and/or changes in curves, to which assets and liabilities are referenced. As these assets and liabilities may have temporary mismatches<br />
of revaluation or maturity, they may impact the stability of income (financial margin) and the levels of solvency (economic value of<br />
equity).<br />
For this purpose, the Bank establishes internal limitations by using sensitivity techniques in the interest rates structures.<br />
Also, the Bank analyzes stress scenarios where interest rates currency, revaluations, changes in share prices, changes in the assets<br />
underlying of options and changes in commissions that may be sensitive to interest rates are sensitized. This stress testing allows<br />
the Bank to measure and control the impact of sudden movements in different risk factors in the Bank’s current ratio, gross margin<br />
and economic value of equity.<br />
The compliance with the limitations established by <strong>Banco</strong> <strong>Security</strong> is monitored on a daily basis in accordance with the definitions<br />
in Chapter III.B.2. of the Compendium of Financial Regulations issued by the Chilean Central Bank.<br />
Furthermore, on a weekly basis the Bank informs the SBIF about positions at risk in the trading ledger investment portfolio and<br />
compliance with limitations. Also, on a monthly basis the Bank informs the SBIF about positions at risk consolidated with its<br />
subsidiaries for the trading ledger and, individually for the banking ledger, which includes the market risk sensitivity of the availablefor-sale<br />
portfolio and the commercial ledger.<br />
The Bank market risk in accordance with the methodology defined in Chapter III.B.2 of the Compendium of Financial Regulations<br />
issued by the Chilean Central Bank is as follows:<br />
