the guarantees; however, we do not consider it probable that we will be required to satisfy these guarantees. Management concluded that the likelihood of any significant amounts being paid by our Company under these guarantees is not probable. As of December 31, 2013, we were not directly liable for the debt of any unconsolidated entity, and we did not have any retained or contingent interest in assets as defined above. 

Our Company recognizes all derivatives as either assets or liabilities at fair value in our consolidated balance sheets. Refer toNote 5 of Notes to Consolidated Financial Statements. 

As of December 31, 2013, the Company had $6,410 million in lines of credit for general corporate purposes. These backup lines of credit expire at various times from2014 through 2018. There were no borrowings under these backup lines of credit during 2013. These credit facilities are subject to normal banking terms and conditions. Some of the financial arrangements require compensating balances, none of which are presently significant to our Company. 

The total accrued benefit liability for pension and other postretirement benefit plans recognized as ofDecember 31, 2013, was $1,869 million. Refer to Note 13 of Notes to Consolidated Financial Statements. This amount is impacted by, among other items, pension expense, funding levels, plan amendments, changes in plan demographics and assumptions, and the investment return on plan assets. Because the accrued liability does not represent expected liquidity needs, we did not include this amount in the contractual obligations table. 

We generally expect to fund all future contributions with cash flows from operating activities. Our international pension plans are generally funded in accordance with local laws and income tax regulations. 

As of December 31, 2013, the projected benefit obligation of the U.S. qualified pension plans was $5,895 million, and the fair value of plan assets was $6,343 million. The projected benefit obligation of all pension plans other than the U.S. qualified pension plans was $2,950 million, and the fair value of all other pension plan assets was $2,403 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 certain 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 $70 million in 2014 and remain near that level through 2027, decreasing annually thereafter. Refer to Note 13 of Notes to Consolidated Financial Statements. 

In 2014, we expect to contribute an additional $175 million to our international pension plans. Refer toNote 13 of Notes to Consolidated Financial Statements. We did not include our estimated contributions to our various plans in the table
