[1] | Total gains or losses represent the total realized and unrealized gains and losses recorded for Level 3 assets and liabilities. Realized gains or losses are reported in the condensed consolidated statements of income.
[2] | Unrealized gains or losses on investment securities are reported in accumulated other comprehensive loss, net of tax, in the condensed consolidated statements of changes in stockholders' equity and comprehensive income.
[3] | Purchases, issuances, sales, and settlements represent Level 3 assets and liabilities that were either purchased, issued, sold, or settled during the period. The amounts are recorded at their end of period fair values.
[4] | Transfers in and/or out represent existing assets and liabilities that were either previously categorized as a higher level and the inputs to the model became unobservable or assets and liabilities that were previously classified as Level 3 and the lowest significant input became observable during the period. These assets and liabilities are recorded at their end of period fair values.
