(A) Substantially all of Power's and PSEG's derivative instruments are contracts subject to master netting agreements. Contracts not subject to master netting or similar agreements are immaterial and did not have any collateral posted or received as of September 30, 2013 and December 31, 2012. PSE&G does not have any derivative contracts subject to master netting or similar agreements.

(B) Represents the netting of fair value balances with the same counterparty (where the right of offset exists) and the application of collateral. All cash collateral received or posted that has been allocated to derivative positions, where the right of offset exists, has been offset in the statement of financial position. As of September 30, 2013 and December 31, 2012, net cash collateral (received) paid of $(2) million and $2 million, respectively, were netted against the corresponding net derivative contract positions. Of the $(2) million as of September 30, 2013, $(1) million of cash collateral was netted against current assets, $(2) million was netted against noncurrent assets and $1 million was netted against current liabilities. Of the $2 million as of December 31, 2012, cash collateral of $(3) million and $5 million were netted against current assets and current liabilities, respectively.
