obligation of the U.S. qualified pension plans was $4,837 million, and the fair value of plan assets was approximately $4,118 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, 2010, the projected benefit obligation of all pension plans other than the U.S. qualified pension plans was approximately $2,455 million, and the fair value of all other pension plan assets was approximately $1,379 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 for these unfunded pension plans to be approximately 

$50 million in 2011 and remain near that level through 2030, decreasing annually thereafter. Refer to Note 13 of Notes to Consolidated Financial Statements. 

In general, we are self-insured for large portions of many different types of claims; however, we do use commercial insurance above our self-insured retentions to reduce the Company's risk of catastrophic loss. Our reserves for the Company's self-insured losses are estimated through actuarial procedures of the insurance industry and by using industry assumptions, adjusted for our specific expectations based on our claim history. As of December 31, 2010, our self-insurance reserves totaled approximately

$502 million. Refer to Note 11 of Notes to Consolidated Financial Statements. We did not include estimated payments related to our self-insurance reserves in the table above. 

Deferred income tax liabilities as of December 31, 2010, were approximately $4,279 million. Refer to Note 14 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 periods. As a result, scheduling deferred income tax liabilities as payments due by period could be misleading, because this scheduling would not relate to liquidity needs.
