Market risk trading portfolio, description |  | For the Bank, the VaR estimate is made under the historical simulation methodology, which consists of observing the behavior of the profits and losses that would have occurred in the current portfolio if the market conditions for a given historical period had been in force, in order to infer the maximum loss on the basis of that information, with a given degree of confidence. The methodology has the advantage of precisely reflecting the historical distribution of the market variables and not requiring any assumptions regarding the distribution of specific probabilities. All the VaR measures are intended to determine the distribution function for a change in the value of a given portfolio, and once that distribution is known, to calculate the percentile related to the necessary degree of confidence, which will be equal to the value at risk by virtue of those parameters. As calculated by the Bank, the VaR is an estimate of the maximum expected loss of market value for a given portfolio over a 1–day horizon, with a 99.00% confidence level. It is the maximum 1–day loss that the Bank could expect to experience in a given portfolio, with a 99.00% confidence level. In other words, it is the loss that the Bank would expect to experience only 1.0% of the time. The VaR provides a single estimate of market risk which is not comparable from one market risk to another. Returns are calculated through the use of a 2–year time window or at least 520 data points obtained since the last reference date for calculation of the VaR going backward in time. | For the Bank, the VaR estimate is made under the historical simulation methodology, which consists of observing the behavior of the profits and losses that would have occurred in the current portfolio if the market conditions for a given historical period had been in force, in order to infer the maximum loss on the basis of that information, with a given degree of confidence.

Capital adequacy requirement, description |  | Under the General Banking Law, banks must maintain regulatory capital of at least 8% of risk-weighted assets, net of required credit losses, as well as a paid-in capital and reserve requirement (“tire capital”) of at least 3% of total assets, also net of credit losses. Regulatory capital and basic capital are calculated on the basis of the Consolidated Financial Statements. As we are the result of a merger between two predecessors with significant market shares in the Chilean market, we are currently required to maintain a minimum regulatory capital to risk-weighted assets ratio of 11%. Regulatory capital is defined as the aggregate of: -the paid-in capital and reserves of a bank, excluding capital attributable to foreign subsidiaries and branches or core capital; -subordinated bonds, valued at their placement price (but decreasing by 20.0% for each year during the period beginning six years before maturity), for an amount of up to 50.0% of its basic capital; -voluntary provisions for credit losses in the amount of up to 1.25% of risk-weighted assets. | Under the General Banking Law, banks must maintain regulatory capital of at least 8% of risk-weighted assets, net of required credit losses, as well as a paid-in capital and reserve requirement (“tire capital”) of at least 3% of total assets, also net of credit losses.
