⁽¹⁾ For all periods presented, the ending balance in net unrealized gains (losses) on cash flow hedges and investment securities available for sale includes unrealized losses of $12.1 million and $13.3 million, respectively, related to residual tax effects remaining in OCI due to previously established deferred tax asset valuation allowances in 2010 and 2011. In accordance with ASC 740-20-45-11(b), under the portfolio approach, these unrealized losses are realized at the time the entire portfolio is sold or disposed.
