MetLife, Inc. Notes to the Consolidated Financial Statements — (Continued) Credit Derivatives In connection with synthetically created credit investment transactions and credit default swaps held in relation to the trading portfolio, the Company writes credit default swaps for which it receives a premium to insure credit risk. Such credit derivatives are included within the non-qualifying derivatives and derivatives for purposes other than hedging table. If a credit event occurs, as defined by the contract, the contract may be cash settled or it may be settled gross by the Company paying the counterparty the specified swap notional amount in exchange for the delivery of par quantities of the referenced credit obligation. The Company’s maximum amount at risk, assuming the value of all referenced credit obligations is zero, was $8.9 billion and $7.7 billion at December 31, 2012 and 2011, respectively. The Company can terminate these contracts at any time through cash settlement with the counterparty at an amount equal to the then current fair value of the credit default swaps. At December 31, 2012 and 2011, the Company would have received $74 million and paid $41 million, respectively, to terminate all of these contracts. The following table presents the estimated fair value, maximum amount of future payments and weighted average years to maturity of written credit default swaps at: December 31, 2012 2011 Rating Agency Designation of Referenced Credit Obligations (1) Estimated Fair Value of Credit Default Swaps Maximum Amount of Future Payments under Credit Default Swaps (2) Weighted Average Years to Maturity (3) Estimated Fair Value of Credit Default Swaps Maximum Amount of Future Payments under Credit Default Swaps (2) Weighted Average Years to Maturity (3) (In millions) (In millions) Aaa/Aa/A Single name credit default swaps (corporate) ................... $10 $ 777 2.7 $ 5 $ 737 3.5 Credit default swaps referencing indices ...................... 42 2,713 2.1 (1) 2,813 3.0 Subtotal .............................................. 52 3,490 2.2 4 3,550 3.1 Baa Single name credit default swaps (corporate) ................... 8 1,314 3.4 (17) 1,234 4.0 Credit default swaps referencing indices ...................... 11 3,750 4.9 (26) 2,847 4.9 Subtotal .............................................. 19 5,064 4.5 (43) 4,081 4.6 Ba Single name credit default swaps (corporate) ................... — 25 2.7 — 25 3.5 Credit default swaps referencing indices ...................... — — — — — — Subtotal .............................................. — 25 2.7 — 25 3.5 B Single name credit default swaps (corporate) ................... — — — — — — Credit default swaps referencing indices ...................... 3 300 4.9 (2) 25 4.8 Subtotal .............................................. 3 300 4.9 (2) 25 4.8 Total .............................................. $74 $8,879 3.6 $(41) $7,681 3.9 Credit Risk on Freestanding Derivatives The Company may be exposed to credit-related losses in the event of nonperformance by counterparties to derivatives. Generally, the current credit exposure of the Company’s derivatives is limited to the net positive estimated fair value of derivatives at the reporting date after taking into consideration the existence of netting agreements and any collateral received pursuant to credit support annexes. The Company manages its credit risk related to OTC derivatives by entering into transactions with creditworthy counterparties, maintaining collateral arrangements and through the use of master agreements that provide for netting of payments by product and currency for periodic settlements and a single net payment to be made by one party upon termination. Because exchange-traded futures and options are effected through regulated exchanges, and positions are marked to market on a daily basis, the Company has minimal exposure to credit-related losses in the event of nonperformance by counterparties to such derivatives. See Note 10 for a description of the impact of credit risk on the valuation of derivatives. Written credit default swaps held in relation to the trading portfolio amounted to $10 million in notional and $0 in fair value at December 31, 2012. Written credit default swaps held in relation to the trading portfolio amounted to $10 million in notional and ($1) million in fair value at December 31, 2011. The Company has also entered into credit default swaps to purchase credit protection on certain of the referenced credit obligations in the table above. As a result, the maximum amounts of potential future recoveries available to offset the $8.9 billion and $7.7 billion from the table above were $150 million and $115 million at December 31, 2012 and 2011, respectively. (1) The rating agency designations are based on availability and the midpoint of the applicable ratings among Moody’s Investors Service (“Moody’s”), S&P and Fitch Ratings. If no rating is available from a rating agency, then an internally developed rating is used. (2) Assumes the value of the referenced credit obligations is zero. (3) The weighted average years to maturity of the credit default swaps is calculated based on weighted average notional amounts. MetLife, Inc. 137
