At each reporting date, the Bank assesses whether there is any objective evidence indicating that the available-for-sale financial assets (debt securities and equity instruments) are impaired.

This assessment includes but is not limited to an analysis of the following information: i) the issuer's economic and financial position, any default or late payments, issuer's solvency, the evolution of its business, short-term projections, trends observed with respect to its earnings and, if applicable, its dividend distribution policy; ii) market-related information such as changes in the general economic situation, changes in the issuer's industry which might affect its ability to pay; iii) changes in the fair value of the security analyzed, and analysis of the reasons of such changes-whether they are specific to the security or the result of the general uncertainty concerning the economy or the country and iv) independent analysts' reports and forecasts and other independent market information.

In the case of equity instruments, when the changes in the fair value of the equity instrument subject to analysis are assessed, the duration and significance of the decline in its market price below cost is taken into account. Nevertheless, it should be noted that the Bank assesses, on a case-by-case basis each of the equity instruments that have incurred losses, and monitors the performance of their market prices, recognizing an impairment loss as soon as it is determined that the recoverable amount could be decreased.

If, after completing the above assessment, the Bank considers that the presence of one or more of these factors affect recovery of the cost of the financial asset, an impairment loss is recognized in the consolidated income statement for the amount of the loss in equity under Other Comprehensive Income. Also, where the Bank does not intend and/or is not able to hold the investment for a sufficient amount of time to recover the cost, the financial asset is written-off through its fair value.

Other Comprehensive Income-Cash flow hedges includes the gains or losses attributable to hedge instruments that qualify as effective hedges. These amounts will remain under this heading until they are recognized in the consolidated income statement in the periods in which the hedged items affect them (see Note 9).

Accordingly, amounts representing valuation losses will be offset in the future by gains generated by the hedged objects.

c) Hedges of net investments in foreign operations and Translation adjustments foreign investment

Other Comprehensive Incomes-Hedges of net investments in foreign operations includes the net amount of changes in the value of hedging instruments in hedges of net investments in foreign operations. In 2017 this hedge was discontinued (Note 9.a5). In 2016 and 2105, no ineffective portion was identified (Note 9.a5).

Other Comprehensive Income-Exchange differences includes the net amount of the differences arising on the translation to Reais of the balances of the consolidated entities whose functional currency is not the Reais (Note 2.a).
