(c) Certain of our discontinued international automotive financing businesses are committed to provide retail automotive receivables to third-party banks in exchange for secured debt. The transaction does not meet the definition of a sale.

(d) The fair value of these commitments is considered in the overall valuation of the related assets.

(e) We are committed to fund the remaining unused balances on home equity lines of credit for certain home equity loans sold into securitization structures (both on- and off-balance sheet structures) if certain deal-specific triggers are met. At December 31, 2012, the commitments to fund home equity lines of credit in off-balance sheet securitizations represented $0 million of the total unfunded commitments.

(f) The unused portion of revolving lines of credit reset at prevailing market rates and, as such, approximate market value.
