Postretirement Benefits other than Pensions
In addition to the Bank’s retirement plans, employees who have met certain age and length of service requirements are eligible for both medical benefits and life insurance coverage during retirement.
The Bank funds benefits payable under the medical and life insurance plans as due and, accordingly, has no plan assets.

At December 31, 2005 and 2004, the weighted-average discount rate assumptions used in developing the postretirement benefit obligation were 5.50 percent and 5.75 percent, respectively.
Discount rates reflect yields available on high-quality corporate bonds that would gener- ate the cash flow necessary to pay the plan’s benefits when due.

Net postretirement benefit costs are actuarially determined using a January 1 measure- ment date. At January 1, 2005 and 2004, the weighted-average discount rate assumptions used to determine net periodic postretirement benefit costs were 5.75 percent and 6.25 percent, respectively.
Net periodic postretirement benefit costs are reported as a component of “Salaries and other benefits.”
A plan amendment that modified the credited service period eligibility requirements cre- ated curtailment gains in 2004.
The Medicare Prescription Drug, Improvement and Modernization Act of 2003 established a prescription drug benefit under Medicare (“Medicare Part D”) and a federal subsidy to sponsors of retiree health care benefit plans that provide benefits that are at least actuari- ally equivalent to Medicare Part D. The benefits provided by the Bank’s plan to certain par- ticipants are at least actuarially equivalent to the Medicare Part D prescription drug bene- fit. The estimated effects of the subsidy, retroactive to January 1, 2004, are reflected in actuarial loss in the accumulated postretirement benefit obligation and net periodic postre- tirement benefit costs.

Postemployment Benefits
The Bank offers benefits to former or inactive employees. Postemployment benefit costs are actuarially determined using a December 31, 2005, measurement date and include the cost of medical and dental insurance, survivor income, and disability benefits. The accrued postemployment benefit costs recognized by the Bank at December 31, 2005 and 2004, were $7 million and $8 million, respectively. This cost is included as a component of “Accrued benefit costs.” Net periodic postemployment benefit costs included in 2005 and 2004 operating expenses were $1 million and $3 million, respectively, and are recorded as a component of “Salaries and other benefits.”
