Question:

pre_text: financial statements .
as of december 31 , 2016 , we had cash and cash equivalents of $ 683 million and debt of $ 10478 million , including the current portion , net of capitalized debt issuance costs .
of the $ 683 million cash and cash equivalents , approximately $ 470 million is held by our foreign entities and would generally be subject to u.s .
income taxation upon repatriation to the u.s .
the majority of our domestic cash and cash equivalents represents net deposits-in-transit at the balance sheet dates and relates to daily settlement activity .
we expect that cash and cash equivalents plus cash flows from operations over the next twelve months will be sufficient to fund our operating cash requirements , capital expenditures and mandatory debt service .
we currently expect to continue to pay quarterly dividends .
however , the amount , declaration and payment of future dividends is at the discretion of the board of directors and depends on , among other things , our investment opportunities , results of operationtt s , financial condition , cash requirements , future prospects , and other factors that may be considered relevant by our board of directors , including legal and contractual restrictions .
additionally , the payment of cash dividends may be limited by covenants in certain debt agreements .
a regular quarterly dividend of $ 0.29 per common share is payable on march 31 , 2017 to shareholders of record as of thef close of business on march 17 , 2017 .
cash flows from operations cash flows from operations were $ 1925 million , $ 1131 million and $ 1165 million in 2016 , 2015 and 2014 respectively .
our net cash provided by operating activities consists primarily of net earnings , adjusted to add backr depreciation and amortization .
ck ash flows from operations increased $ 794 million in 2016 and decreased $ 34 million in 2015 .
the 2016 increase in cash flows from operations is primarily due to increased net earnings , after the add back of non-cash depreciation and amortization , as a result of sungard operations being included for the full year .
the 2015 decrease in cash flows from operations is primarily due to a tax payment of $ 88 million of income taxes relating to the sale of check warranty contracts and other assets in the gaming industry and lower net earnings , partially offset by changes in working capital .
capital expenditures and other investing activities our principal capital expenditures are for computer software ( purchased and internally developed ) and addrr itions to property and equipment .
we invested approximately $ 616 million , $ 415 million and $ 372 million in capital expenditures during 2016 , 2015 and 2014 , respectively .
we expect to invest approximately 6%-7% ( 6%-7 % ) of 2017 revenue in capital expenditures .
we used $ 0 million , $ 1720 million and $ 595 million of cash during 2016 , 2015 and 2014 , respectively , for acquisitions and other equity investments .
see note 3 of the notes to consolidated financial statements for a discussion of the more significant items .
cash provided by net proceeds from sale of assets in 2015 relates principally to the sale of check warranty contracts and other assets in the gaming industry discussed in note 15 of the notes to consolidated financial statements .
