note 21 .expenses during the fourth quarter of 2008 , we elected to provide support to certain investment accounts managed by ssga through the purchase of asset- and mortgage-backed securities and a cash infusion , which resulted in a charge of $ 450 million .ssga manages certain investment accounts , offered to retirement plans , that allow participants to purchase and redeem units at a constant net asset value regardless of volatility in the underlying value of the assets held by the account .the accounts enter into contractual arrangements with independent third-party financial institutions that agree to make up any shortfall in the account if all the units are redeemed at the constant net asset value .the financial institutions have the right , under certain circumstances , to terminate this guarantee with respect to future investments in the account .during 2008 , the liquidity and pricing issues in the fixed-income markets adversely affected the market value of the securities in these accounts to the point that the third-party guarantors considered terminating their financial guarantees with the accounts .although we were not statutorily or contractually obligated to do so , we elected to purchase approximately $ 2.49 billion of asset- and mortgage-backed securities from these accounts that had been identified as presenting increased risk in the current market environment and to contribute an aggregate of $ 450 million to the accounts to improve the ratio of the market value of the accounts 2019 portfolio holdings to the book value of the accounts .we have no ongoing commitment or intent to provide support to these accounts .the securities are carried in investment securities available for sale in our consolidated statement of condition .the components of other expenses were as follows for the years ended december 31: .

in september and october 2008 , lehman brothers holdings inc. , or lehman brothers , and certain of its affiliates filed for bankruptcy or other insolvency proceedings .while we had no unsecured financial exposure to lehman brothers or its affiliates , we indemnified certain customers in connection with these and other collateralized repurchase agreements with lehman brothers entities .in the then current market environment , the market value of the underlying collateral had declined .during the third quarter of 2008 , to the extent these declines resulted in collateral value falling below the indemnification obligation , we recorded a reserve to provide for our estimated net exposure .the reserve , which totaled $ 200 million , was based on the cost of satisfying the indemnification obligation net of the fair value of the collateral , which we purchased during the fourth quarter of 2008 .the collateral , composed of commercial real estate loans which are discussed in note 5 , is recorded in loans and leases in our consolidated statement of condition. .
