Notes to consolidated financial statements Note 12 – Securities Securities are primarily classified as AFS or trading.
Securities classified as trading assets are discussed in Note 3 on pages 196–214 of this Annual Report.
Predominantly all of the AFS securities portfolio is held by CIO in connection with its asset-liability management objectives.
At December 31, 2012, the average credit rating of the debt securities comprising the AFS portfolio was AA+ (based upon external ratings where available, and where not available, based primarily upon internal ratings which correspond to ratings as defined by S&P and Moody’s).
AFS securities are carried at fair value on the Consolidated Balance Sheets.
Unrealized gains and losses, after any applicable hedge accounting adjustments, are reported as net increases or decreases to accumulated other comprehensive income/(loss).
The specific identification method is used to determine realized gains and losses on AFS securities, which are included in securities gains/ (losses) on the Consolidated Statements of Income.
Other-than-temporary impairment AFS debt and equity securities in unrealized loss positions are analyzed as part of the Firm’s ongoing assessment of other-than-temporary impairment (“OTTI”).
For most types of debt securities, the Firm considers a decline in fair value to be other-than-temporary when the Firm does not expect to recover the entire amortized cost basis of the security.
For beneficial interests in securitizations that are rated below “AA” at their acquisition, or that can be contractually prepaid or otherwise settled in such a way that the Firm would not recover substantially all of its recorded investment, the Firm considers an OTTI to have occurred when there is an adverse change in expected cash flows.
For AFS equity securities, the Firm considers a decline in fair value to be other-than-temporary if it is probable that the Firm will not recover its amortized cost basis.
Potential OTTI is considered using a variety of factors, including the length of time and extent to which the market value has been less than cost; adverse conditions specifically related to the industry, geographic area or financial condition of the issuer or underlying collateral of a security; payment structure of the security; changes to the rating of the security by a rating agency; the volatility of the fair value changes; and the Firm’s intent and ability to hold the security until recovery.
For debt securities, the Firm recognizes OTTI losses in earnings if the Firm has the intent to sell the debt security, or if it is more likely than not that the Firm will be required to sell the debt security before recovery of its amortized cost basis.
In these circumstances the impairment loss is equal to the full difference between the amortized cost basis and the fair value of the securities.
When the Firm has the intent and ability to hold AFS debt securities in an unrealized loss position, it evaluates the expected cash flows to be received and determines if a credit loss exists.
In the event of a credit loss, only the amount of impairment associated with the credit loss is recognized in income.
Amounts relating to factors other than credit losses are recorded in OCI.
The Firm’s cash flow evaluations take into account the factors noted above and expectations of relevant market and economic data as of the end of the reporting period.
For securities issued in a securitization, the Firm estimates cash flows considering underlying loan-level data and structural features of the securitization, such as subordination, excess spread, overcollateralization or other forms of credit enhancement, and compares the losses projected for the underlying collateral (“pool losses”) against the level of credit enhancement in the securitization structure to determine whether these features are sufficient to absorb the pool losses, or whether a credit loss exists.
The Firm also performs other analyses to support its cash flow projections, such as first-loss analyses or stress scenarios.
For equity securities, OTTI losses are recognized in earnings if the Firm intends to sell the security.
In other cases the Firm considers the relevant factors noted above, as well as the Firm’s intent and ability to retain its investment for a period of time sufficient to allow for any anticipated recovery in market value, and whether evidence exists to support a realizable value equal to or greater than the carrying value.
Any impairment loss on an equity security is equal to the full difference between the amortized cost basis and the fair value of the security.
Realized gains and losses The following table presents realized gains and losses and credit losses that were recognized in income from AFS securities.
## Table 2 ##
(a) Proceeds from securities sold were within approximately 4% of amortized cost in 2012 and 2011, and within approximately 3% of amortized cost in 2010.
(b) Includes other-than-temporary impairment losses recognized in income on certain prime mortgage-backed securities and obligations of U. S.  states and municipalities for the year ended December 31, 2012; certain prime mortgage-backed securities for the year ended December 31, 2011; and certain prime mortgage-backed securities and obligations of U. S.  states and municipalities for the year ended December 31, 2010.
(c) Represents the excess of the amortized cost over the fair value of certain non-U.
S.  corporate debt, and non-U.
S.  government debt securities the Firm intends to sell.
(d) Excludes realized losses of $24 million on sales of non-U.
S.  corporate debt, non-U.
