( a ) represents depreciation and amortization , gains and losses on derivative and foreign exchange transactions , deferred income taxes , provisions for uncollectible accounts , pension and postretirement benefit expense , stock compensation expense , impairment charges and other non-cash items . cash from operating activities remained strong throughout the 2010 to 2012 time period . operating cash flow was favorably impacted in 2012 , compared with 2011 , by lower contributions into our defined benefit pension and postretirement benefit plans ; however , this was partially offset by changes in our working capital position , which was impacted by overall growth in the business . the change in the cash flows for income tax receivables and payables in 2011 and 2010 was primarily related to the timing of discretionary pension contributions during 2010 , as discussed further in the following paragraph . except for discretionary or accelerated fundings of our plans , contributions to our company-sponsored pension plans have largely varied based on whether any minimum funding requirements are present for individual pension plans . 2022 in 2012 , we made a $ 355 million required contribution to the ups ibt pension plan . 2022 in 2011 , we made a $ 1.2 billion contribution to the ups ibt pension plan , which satisfied our 2011 contribution requirements and also approximately $ 440 million in contributions that would not have been required until after 2011 . 2022 in 2010 , we made $ 2.0 billion in discretionary contributions to our ups retirement and ups pension plans , and $ 980 million in required contributions to our ups ibt pension plan . 2022 the remaining contributions in the 2010 through 2012 period were largely due to contributions to our international pension plans and u.s . postretirement medical benefit plans . as discussed further in the 201ccontractual commitments 201d section , we have minimum funding requirements in the next several years , primarily related to the ups ibt pension , ups retirement and ups pension plans . as of december 31 , 2012 , the total of our worldwide holdings of cash and cash equivalents was $ 7.327 billion . approximately $ 4.211 billion of this amount was held in european subsidiaries with the intended purpose of completing the acquisition of tnt express n.v . ( see note 16 to the consolidated financial statements ) . excluding this portion of cash held outside the u.s . for acquisition-related purposes , approximately 50%-60% ( 50%-60 % ) of the remaining cash and cash equivalents are held by foreign subsidiaries throughout the year . the amount of cash held by our u.s . and foreign subsidiaries fluctuates throughout the year due to a variety of factors , including the timing of cash receipts and disbursements in the normal course of business . cash provided by operating activities in the united states continues to be our primary source of funds to finance domestic operating needs , capital expenditures , share repurchases and dividend payments to shareowners . to the extent that such amounts represent previously untaxed earnings , the cash held by foreign subsidiaries would be subject to tax if such amounts were repatriated in the form of dividends ; however , not all international cash balances would have to be repatriated in the form of a dividend if returned to the u.s . when amounts earned by foreign subsidiaries are expected to be indefinitely reinvested , no accrual for taxes is provided. .
