( 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. .
