Notes to Consolidated Financial Statements Derivatives with Credit-Related Contingent Features Certain of the firm’s derivatives have been transacted under bilateral agreements with counterparties who may require the firm to post collateral or terminate the transactions based on changes in the firm’s credit ratings.
The firm assesses the impact of these bilateral agreements by determining the collateral or termination payments that would occur assuming a downgrade by all rating agencies.
A downgrade by any one rating agency, depending on the agency’s relative ratings of the firm at the time of the downgrade, may have an impact which is comparable to the impact of a downgrade by all rating agencies.
The table below presents the aggregate fair value of net derivative liabilities under such agreements (excluding application of collateral posted to reduce these liabilities), the related aggregate fair value of the assets posted as collateral, and the additional collateral or termination payments that could have been called at the reporting date by counterparties in the event of a one-notch and two-notch downgrade in the firm’s credit ratings.
## Table 0 ##
Credit Derivatives The firm enters into a broad array of credit derivatives in locations around the world to facilitate client transactions and to manage the credit risk associated with marketmaking and investing and lending activities.
Credit derivatives are actively managed based on the firm’s net risk position.
Credit derivatives are individually negotiated contracts and can have various settlement and payment conventions.
Credit events include failure to pay, bankruptcy, acceleration of indebtedness, restructuring, repudiation and dissolution of the reference entity.
Credit Default Swaps.
Single-name credit default swaps protect the buyer against the loss of principal on one or more bonds, loans or mortgages (reference obligations) in the event the issuer (reference entity) of the reference obligations suffers a credit event.
The buyer of protection pays an initial or periodic premium to the seller and receives protection for the period of the contract.
If there is no credit event, as defined in the contract, the seller of protection makes no payments to the buyer of protection.
However, if a credit event occurs, the seller of protection is required to make a payment to the buyer of protection, which is calculated in accordance with the terms of the contract.
Credit Indices, Baskets and Tranches.
Credit derivatives may reference a basket of single-name credit default swaps or a broad-based index.
If a credit event occurs in one of the underlying reference obligations, the protection seller pays the protection buyer.
The payment is typically a pro-rata portion of the transaction’s total notional amount based on the underlying defaulted reference obligation.
In certain transactions, the credit risk of a basket or index is separated into various portions (tranches), each having different levels of subordination.
The most junior tranches cover initial defaults and once losses exceed the notional amount of these junior tranches, any excess loss is covered by the next most senior tranche in the capital structure.
Total Return Swaps.
A total return swap transfers the risks relating to economic performance of a reference obligation from the protection buyer to the protection seller.
Typically, the protection buyer receives from the protection seller a floating rate of interest and protection against any reduction in fair value of the reference obligation, and in return the protection seller receives the cash flows associated with the reference obligation, plus any increase in the fair value of the reference obligation.
METLIFE, INC.  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) other reinsured losses in connection with Hurricanes Katrina and Wilma and otherwise.
In addition, lawsuits, including purported class actions, have been filed in Louisiana, Mississippi and Alabama challenging denial of claims for damages caused to property during Hurricane Katrina.
MPC is a named party in some of these lawsuits.
In addition, rulings in cases in which MPC is not a party may affect interpretation of its policies.
MPC intends to vigorously defend these matters.
However, any adverse rulings could result in an increase in the Company’s hurricane-related claim exposure and losses.
Based on information known by management, it does not believe that additional claim losses resulting from Hurricane Katrina will have a material adverse impact on the Company’s consolidated financial statements.
Argentina The Argentinean economic, regulatory and legal environment, including interpretations of laws and regulations by regulators and courts, is uncertain.
Potential legal or governmental actions related to pension reform, fiduciary responsibilities, performance guarantees and tax rulings could adversely affect the results of the Company.
Upon acquisition of Citigroup’s insurance operations in Argentina, the Company established insurance liabilities, most significantly death and disability policy liabilities, based upon its interpretation of Argentinean law and the Company’s best estimate of its obligations under such law.
In 2006, a decree was issued by the Argentine Government regarding the taxability of pesification-related gains resulting in the reduction of certain tax liabilities.
See Note 2.
Commitments Leases In accordance with industry practice, certain of the Company’s income from lease agreements with retail tenants are contingent upon the level of the tenants’ sales revenues.
Additionally, the Company, as lessee, has entered into various lease and sublease agreements for office space, data processing and other equipment.
Future minimum rental and sublease income, and minimum gross rental payments relating to these lease agreements are as follows:
## Table 1 ##

The Company anticipates that these amounts will be invested in partnerships over the next five years.
Mortgage Loan Commitments The Company commits to lend funds under mortgage loan commitments.
The amounts of these mortgage loan commitments were $4.0 billion and $3.0 billion at December 31, 2006 and 2005, respectively.
Commitments to Fund Bank Credit Facilities and Bridge Loans The Company commits to lend funds under bank credit facilities and bridge loans.
The amounts of these unfunded commitments were $1.9 billion and $346 million at December 31, 2006 and 2005, respectively.
Other Commitments MICC is a member of the Federal Home Loan Bank of Boston (the “FHLB of Boston”) and holds $70 million of common stock of the FHLB of Boston, which is included in equity securities on the Company’s consolidated balance sheets.

MICC maintains control over these pledged assets, and may use, commingle, encumber or dispose of any portion of the collateral as long as there is no event of default and the remaining qualified collateral is sufficient to satisfy the collateral maintenance level.
The funding agreements and the related security agreement represented by this blanket lien provide that upon any event of default by MICC, the FHLB of Boston’s recovery is limited to the amount of MICC’s liability under the outstanding funding agreements.
The amount of the Company’s liability for funding agreements with the FHLB of Boston was $926 million and $1.1 billion at December 31, 2006 and 2005, respectively, which is included in PABs.
MetLife Bank is a member of the FHLB of NY and holds $54 million and $43 million of common stock of the FHLB of NY, at December 31, 2006 and 2005, respectively, which is included in equity securities on the Company’s consolidated balance sheet.

accumulated other comprehensive income, which is included as a component of total consolidated stockholders’ equity.
The following table summarizes the adjustments to the December 31, 2006 consolidated balance sheet in order to effect the adoption of SFAS 158.
## Table 2 ##
A December 31 measurement date is used for all the Company’s defined benefit pension and other postretirement benefit plans.
The benefit obligations and funded status of the Subsidiaries’ defined benefit pension and other postretirement benefit plans, as determined in accordance with the applicable provisions described above, were as follows
## Table 3 ##
The increase in expense from 2004 to 2005 was primarily a result of increases in service and interest cost as well as increased amortization of net actuarial losses resulting largely from lower discount rates.
Despite a continued increase in amortization of net actuarial losses due to lower discount rates in recent years, the other postretirement benefit expense decreased from 2005 to 2006 due to changes in plan benefits that resulted in decreased service and interest cost and increases in amortization of prior service credits.
The estimated net actuarial losses and prior service credit for the other postretirement benefit plans that will be amortized from accumulated other comprehensive income into net periodic benefit cost over the next year are $14 million and $36 million, respectively.
The weighted average discount rate used to calculate the net periodic postretirement cost was 5.82%, 5.98% and 6.20% for the years ended December 31, 2006, 2005 and 2004, respectively.
The weighted average expected rate of return on plan assets used to calculate the net other postretirement benefit cost for the years ended December 31, 2006, 2005 and 2004 was 7.42%, 7.51% and 7.91%, respectively.
The expected rate of return on plan assets is based on anticipated performance of the various asset sectors in which the plan invests, weighted by target allocation percentages.
Anticipated future performance is based on long-term historical returns of the plan assets by sector, adjusted for the Subsidiaries’ longterm expectations on the performance of the markets.
While the precise expected return derived using this approach will fluctuate from year to year, the Subsidiaries’ policy is to hold this long-term assumption constant as long as it remains within reasonable tolerance from the derived rate.
The actual net return on the investments has been an approximation of the estimated return for the other postretirement plans in 2006, 2005 and 2004.
Based on the December 31, 2006 asset balances, a 25 basis point increase (decrease) in the expected rate of return on plan assets would result in a decrease (increase) in net periodic benefit cost of $3 million for the other postretirement plans.
Pension and Other Postretirement Benefit Plan Assets Pension Plan Assets Substantially all assets of the pension plans are invested within group annuity and life insurance contracts issued by the Subsidiaries.
The majority of assets are held in separate accounts established by the Subsidiaries.
The account values of assets held with the Subsidiaries were $6,205 million and $5,432 million as of December 31, 2006 and 2005, respectively.
The terms of these contracts are consistent in all material respects with those the Subsidiaries offer to unaffiliated parties that are similarly situated.
Net assets invested in separate accounts are stated at the aggregate fair value of units of participation.
Such value reflects accumulated contributions, dividends and realized and unrealized investment gains or losses apportioned to such contributions, less withdrawals, distributions, allocable expenses relating to the purchase, sale and maintenance of the assets and an allocable part of such separate accounts’ investment expenses.
Separate account investments in fixed income and equity securities are generally carried at published market value, or if published market values are not readily available, at estimated market values.
Investments in short-term fixed income securities are generally reflected as cash equivalents and carried at fair value.
Real estate investments are carried at estimated fair value based on appraisals performed by third-party real estate appraisal firms, and generally, determined by discounting projected cash flows over periods of time and at interest rates deemed appropriate for each investment.
Information on the physical value of the property and the sales prices of comparable properties is used to corroborate fair value estimates.
Estimated fair value of hedge fund net assets is generally determined by third-party pricing vendors using quoted market prices or through the use of pricing models which are affected by changes in interest rates, foreign currency exchange rates, financial indices, credit spreads, market supply and demand, market volatility and liquidity.
The following table summarizes the actual and target weighted-average allocations of pension plan assets within the separate accounts:
