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 .

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. .

Question: Analyse this data from a financial earnings document. what percent of 2008's total other expenses is the total customer indemnification reserve?
