redeem $40 of our February 2019 Notes at a price of 103.000%. On February 13, 2015 we elected to redeem the remaining $15  of our February 2019 Notes ef fective March 16, 2015 at a price equal to 103.250%. At December 31, 2014, we were in compliance with the covenants of our financing agreements. Under the revolving  facility and our senior notes, we are required to comply with certain incurrence-based covenants customary for facilities of  these types. The incurrence-based covenants in the revolving facility permit us to, among other things, (i) issue foreign  subsidiary indebtedness, (ii) incur general secured indebtedness and (iii) incur additional unsecured debt so long as the pro  forma minimum fixed char ge coverage ratio is at least 1.0:1.0. We may also make dividend payments in respect of our common  stock as well as certain investments and acquisitions so long as there is (i) at least $100 of pro forma excess borrowing  availability or (ii) at least $75 of pro forma excess borrowing availability and the pro forma minimum fixed char ge coverage  ratio is at least 1.0:1.0. The indentures governing our senior notes include similar incurrence-based covenants that may subject  us to additional specified limitations. Our Board of Directors approved an expansion of our existing common stock share repurchase program from $1,000 to  $1,400 on July 30, 2014. The share repurchase program expires on December 31, 2015. During 2014, we paid $260 to acquire  12,215,451 shares of common stock in the open market, leaving $31 1 available under the program for further share  repurchases. We plan to repurchase shares utilizing available excess cash either in the open market or through privately  negotiated transactions. The stock repurchases are subject to prevailing market conditions and other considerations. From time to time, depending upon market, pricing and other conditions, as well as our cash balances and liquidity , we  may seek to acquire our senior notes or other indebtedness or our common stock through open market purchases, privately  negotiated transactions, tender of fers, exchange offers or otherwise, upon such terms and at such prices as we may determine  (or as may be provided for in the indentures governing the notes), for cash, securities or other consideration.  There can be no  assurance that we will pursue any such transactions in the future, as the pursuit of any alternative will depend upon numerous  factors such as market conditions, our financial performance and the limitations applicable to such transactions under our  financing and governance documents. The table above summarizes our consolidated statement of cash flows. During 2013, we received a $61 payment on a  payment-in-kind note receivable. The payment included $33 of principal and $28 of interest, $26 of which related to prior  years. In January 2014, we sold the payment-in-kind note receivable to a third party for $75. The proceeds included $35 of  principal and $40 of interest related to prior years.The principal portion of the payment has been classified as cash provided  by investing activities and the interest portion has been classified as cash provided by operating activities. 2014 2013 2012 Cash provided by (used for) changes in working capital $ (39 ) $ 104 $ 21 Other cash provided by operations 549 473 318 Net cash provided by operating activities 510 577 339 Net cash used in investing activities (246 ) (222 ) (161 ) Net cash used in financing activities (254 ) (150 ) (55 ) Net increase in cash and cash equivalents $ 10 $ 205 $ 123 Cash Flow Operating activities  — Exclusive of working capital, other cash provided by operations was $549 during 2014 compared to  $473 during 2013 and $318 during 2012. The increase during 2014 was primarily attributable to lower year -over-year pension  contributions of $41 and higher year -over-year cash received on our payment-in-kind note receivable attributed to interest of  $14. Lower cash taxes and restructuring payments in 2014 contributed an additional $20 and $14 to improved operating cash  flows. The increase during 2013 was primarily attributable to $40 of contributions to the U.S. defined benefit pension plans in  2013 as compared to $212 in 2012 and the receipt in April 2013 of $28 of interest on a payment-in-kind note receivable,  partially offset by lower operating earnings and higher cash taxes. Working capital used cash of $39 in 2014 versus generating cash of $104 in 2013. Cash of $32 was used to finance  increased receivables in 2014 versus cash of $12 generated from declining receivables in 2013. Cash of $56 was used to fund  higher inventories in 2014 versus cash of $50 generated from lower inventory levels. Increases in accounts payable and other  net liabilities provided cash of $49 and $42 in 2014 and 2013. Increased working capital levels at the end of 2014 were due in  part to December sales in 2014 being higher than in 2013. Additionally, supplier transitions in process at the end of 2014 in our  Commercial Vehicle business contributed to increased inventory levels.  31
