[1] Fair values shown represent the Company’s net exposure to counterparties related to the Company’s OTC derivative products. Amounts include centrally cleared derivatives. The table does not include listed derivatives and the effect of any related hedges utilized by the Company.
[2] Obligor credit ratings are determined by the Company’s Credit Risk Management Department.
[3] Amounts represent the netting of receivable balances with payable balances for the same counterparty across maturity categories. Receivable and payable balances with the same counterparty in the same maturity category are netted within such maturity category, where appropriate. Cash collateral received is netted on a counterparty basis, provided legal right of offset exists.
