Other-Than-Temporary Impairment

Management evaluates all investment products in an unrealized loss position for other-than-temporary impairment ("OTTI") on at least a quarterly basis. Individual securities are further assessed for OTTI as deemed necessary. An unrealized loss exists when the current fair value of an individual security is less than its amortized cost basis. The OTTI assessment is a subjective process requiring the use of judgments and assumptions. During the securities-level assessments, consideration is given to (1) the intent not to sell and probability that the Company will not be required to sell the security before recovery of its cost basis to allow for any anticipated recovery in fair value, (2) the financial condition and near-term prospects of the issuer, as well as company news and current events, and (3) the ability to collect the future expected cash flows. Key assumptions utilized to forecast expected cash flows may include loss severity, expected cumulative loss percentage, cumulative loss percentage to date, weighted average FICO and weighted average LTV ratio, rating or scoring, credit ratings and market spreads, as applicable.

The Company assesses and recognizes OTTI in accordance with applicable accounting standards. Under these standards, if the Company determines that impairment on its debt securities exists and it has made the decision to sell the security or it is more likely than not that the Company will be required to sell the security prior to recovery of its amortized cost basis, it recognizes the entire portion of the unrealized loss in earnings. If the Company has not made a decision to sell the security and it does not expect that it will be required to sell the security prior to the recovery of the amortized cost basis but the Company has determined that OTTI exists, it recognizes the credit-related portion of the decline in value of the security in earnings.

As a result of rising market interest rates, management made the decision during the second quarter of 2013 to reposition its balance sheet. Consistent with this strategy, the Company designated certain available-for-sale securities with a book value of $2.5 billion to be sold, which were in an unrealized loss position due to changes in market rates and asset spreads. The intent to sell these securities resulted in the Company recording $63.6 million of OTTI in the Condensed Consolidated Statement of Operations during the second quarter of 2013. The Company did not record any OTTI in earnings related to its investment securities in the first quarter of 2013 or in the three-month and six-month periods ended June 30, 2014.

Management has concluded that the remaining unrealized losses on its debt and equity securities for which it has not recognized OTTI (which was comprised of 228 individual securities at June 30, 2014) are temporary in nature since (1) they are not related to the underlying credit quality of the issuers, (2) the entire contractual principal and interest due on these securities is currently expected to be recoverable, (3) the Company does not intend to sell these investments at a loss and (4) it is more likely than not that the Company will not be required to sell the investments before recovery of the amortized cost basis, which may be at maturity. Accordingly, the Company has concluded that the impairment on these securities is not other-than-temporary.

The Company uses the specific identification method to determine the cost of the securities sold and the gain or loss recognized.

The net gain realized for the three-month period ended June 30, 2014 was primarily comprised of the sale of state and municipal securities with a book value of $89.0 million for a gain of $5.2 million, the sale of corporate debt securities with a book value of $63.2 million for a gain of $2.7 million, and the sale of MBS with a book value of $21.6 million for a gain of $1.3 million. The net gain realized for the six-month period ended June 30, 2014 was primarily comprised of the sale of state and municipal securities with a book value of $89.0 million for a gain of $5.2 million, the sale of corporate debt securities with a book value of $346.4 million for a gain of $4.6 million, and the sale of MBS with a book value of $21.6 million for a gain of $1.3 million. The net gain realized, excluding OTTI, for the three-month period ended June 30, 2013 was primarily comprised of the sale of collateralized mortgage obligations with a book value of $2.7 billion for a gain of $35.7 million, offset by fair market value changes on derivative positions related to investment sales. The net gain realized, excluding OTTI, for the six-month period ended June 30, 2013 was primarily comprised of the sale of collateralized mortgage obligations with a book value of $4.1 billion for a gain of $69.0 million and the sale of corporate debt securities with a book value of $905.7 million for a gain of $34.7 million.

Trading Securities

The Company held $125.1 million of trading securities as of June 30, 2014. There were no trading securities at December 31, 2013. The Company recognized $1.5 million of gains on trading securities for the three-month and six-month periods ended June 30, 2014, which included $1.7 million of gains on trading securities sold, offset by $0.2 million of unrealized losses on trading securities still held as of June 30, 2014. Gains and losses on trading securities are recorded within Mortgage banking income, net, in the Company's Condensed Consolidated Statement of Operations.

Other Investments

Other investments primarily include the Company's investment in the stock of the FHLB of Pittsburgh and the FRB with carrying amounts of $828.6 million and $800.5 million as of June 30, 2014 and December 31, 2013, respectively. The stocks do not have readily determinable fair values because their ownership is restricted and they lack a market. The stocks can be sold back only at their par value of $100 per share and only to FHLBs or the FRB. Accordingly, these stocks are carried at cost. During the three-month and six-month periods ended June 30, 2014, the Company sold $11.9 million and $166.0 million, respectively, of FHLB stock at par. There was no gain or loss associated with these sales.

The Company evaluates these investments for impairment based on the ultimate recoverability of the par value, rather than by recognizing temporary declines in value.
