(5) 
Represents structured deposits risk-managed on a fair value basis for which we have elected to apply the fair value option.

Changes in Fair Value of Level 3 Assets and Liabilities
The following table summarizes additional information about changes in the fair value of Level 3 assets and liabilities during year ended December 31, 2012 and 2011. As a risk management practice, we may risk manage the Level 3 assets and liabilities, in whole or in part, using securities and derivative positions that are classified as Level 1 or Level 2 measurements within the fair value hierarchy. Since those Level 1 and Level 2 risk management positions are not included in the table below, the information provided does not reflect the effect of such risk management activities related to the Level 3 assets and liabilities.

As of December 31, 2012 and 2011, the fair value of the loans held for sale was below cost. Certain residential mortgage loans held for sale have been classified as a Level 3 fair value measurement within the fair value hierarchy as the underlying real estate properties which determine fair value are illiquid assets as a result of market conditions and significant inputs in estimating fair value were unobservable. Additionally, the fair value of these properties is affected by, among other things, the location, the payment history and the completeness of the loan documentation.
(2) 
Represents impaired commercial loans. Certain commercial loans have undergone troubled debt restructurings and are considered impaired. As a matter of practical expedient, we measure the credit impairment of a collateral-dependent loan based on the fair value of the collateral asset. The collateral often involves real estate properties that are illiquid due to market conditions. As a result, these commercial loans are classified as a Level 3 fair value measurement within the fair value hierarchy.
(3) 
Real estate owned are required to be reported on the balance sheet net of transactions costs. The real estate owned amounts in the table above reflect the fair value unadjusted for transaction costs.
(4) 
Over the past few years, we have been building several new retail banking platforms as part of an initiative to build common platforms across HSBC. During 2011, we decided to cancel certain projects that were developing software for these new platforms and pursue alternative information technology platforms. Also during 2011, HSBC completed a comprehensive strategic review of all platforms under development which resulted in additional projects being canceled. As a result, we collectively recorded $110 million of impairment charges in 2011 relating to the impairment of certain previously capitalized software development costs which we determined were no longer realizable. The impairment charges were recorded in other expenses in our consolidated statement of income and is included in the results of our segments principally in RBWM and CMB.

We utilize Standard & Poor's ("S&P") as the primary source of credit ratings in the tables above. If S&P ratings are not available, ratings by Moody's and Fitch are used in that order.
Other domestic debt and foreign debt securities (corporate and government) - A significant portion of the domestic and foreign securities are classified as Level 3 measurements. For non-callable corporate securities, a credit spread scale is created for each issuer. These spreads are then added to the equivalent maturity U.S. Treasury yield to determine current pricing. Credit spreads are obtained from the new market, secondary trading levels and dealer quotes. For securities with early redemption features, an option adjusted spread (“OAS”) model is incorporated to adjust the spreads determined above. Additionally, we survey the broker/dealer community to obtain relevant trade data including benchmark quotes and updated spreads.
Equity securities – Except for those legacy investments in hedge funds, since most of our securities are transacted in active markets, fair value measurements are determined based on quoted prices for the identical security. For mutual fund investments, we receive monthly statements from the investment manager with the estimated fair value.
