158. Because the accrued liability does not represent expected liquidity needs, we did not include this amount in the contractual obligations table. 

The Pension Protection Act of 2006 ("PPA") was enacted in August 2006 and established, among other things, new standards for funding of U.S. defined benefit pension plans. During 2008, the funded status of the Company's primary U.S. defined benefit pension plan declined as a result of the overall stock market decline. In early 2009, the Company contributed approximately $175 million to this plan. Subsequent to this contribution, the plan is sufficiently funded to maintain maximum flexibility as outlined in the PPA. However, we will consider additional funding at a later date this year based on asset performance during the beginning of the year. We generally expect to fund all future contributions with cash flows from operating activities. 

Our international pension plans are funded in accordance with local laws and income tax regulations. We do not expect contributions to these plans to be material in 2009 or thereafter. Therefore, no amounts have been included in the table above. 

As of December 31, 2008, the projected benefit obligation of the U.S. qualified pension plans was $1,918 million, and the fair value of plan assets was approximately $1,442 million. The majority of this underfunding was due to the negative impact that the recent credit crisis and financial system instability had on the value of our pension plan assets. As of December 31, 2008, the projected benefit obligation of all pension plans other than the U.S. qualified pension plans was approximately $1,700 million, and the fair value of all other pension plan assets was approximately $848 million. The majority of this underfunding is attributable to an international pension plan for certain non- U.S. employees that is unfunded due to tax law restrictions, as well as our unfunded U.S. nonqualified pension plans. These U.S. nonqualified pension plans provide, for certain associates, benefits that are not permitted to be funded through a qualified plan because of limits imposed by the Internal Revenue Code of 1986. The expected benefit payments for these unfunded pension plans are not included in the table above. However, we anticipate annual benefit payments to be approximately $40 million in 2009 and remain near that level through 2032, decreasing annually thereafter. Refer to Note 16 of Notes to Consolidated Financial Statements. 

Deferred income tax liabilities as of December 31, 2008 were approximately $914 million. Refer to Note 17 of Notes to Consolidated Financial Statements. This amount is not included in the total contractual obligations table because we believe this presentation would not be meaningful. Deferred income tax liabilities are calculated based on temporary differences between the tax bases of assets and liabilities and their respective book bases, which will result in taxable amounts in future years when the liabilities are settled at their reported financial statement amounts. The results of these calculations do not have a direct connection with the amount of cash taxes to be paid in any future
