we measure cash flow as net cash provided by operating activities reduced by expenditures for property additions .we use this non-gaap financial measure of cash flow to focus management and investors on the amount of cash available for debt repayment , dividend distributions , acquisition opportunities , and share repurchases .our cash flow metric is reconciled to the most comparable gaap measure , as follows: .
[['( dollars in millions )', '2012', '2011', '2010'], ['net cash provided by operating activities', '$ 1758', '$ 1595', '$ 1008'], ['additions to properties', '-533 ( 533 )', '-594 ( 594 )', '-474 ( 474 )'], ['cash flow', '$ 1225', '$ 1001', '$ 534'], ['year-over-year change', '22.4% ( 22.4 % )', '87.5% ( 87.5 % )', '']]
year-over-year change 22.4 % (  % ) 87.5 % (  % ) year-over-year changes in cash flow ( as defined ) were driven by improved performance in working capital resulting from the benefit derived from the pringles acquisition , as well as changes in the level of capital expenditures during the three-year period .investing activities our net cash used in investing activities for 2012 amounted to $ 3245 million , an increase of $ 2658 million compared with 2011 primarily attributable to the $ 2668 acquisition of pringles in capital spending in 2012 included investments in our supply chain infrastructure , and to support capacity requirements in certain markets , including pringles .in addition , we continued the investment in our information technology infrastructure related to the reimplementation and upgrade of our sap platform .net cash used in investing activities of $ 587 million in 2011 increased by $ 122 million compared with 2010 , reflecting capital projects for our reimplementation and upgrade of our sap platform and investments in our supply chain .cash paid for additions to properties as a percentage of net sales has decreased to 3.8% ( 3.8 % ) in 2012 , from 4.5% ( 4.5 % ) in 2011 , which was an increase from 3.8% ( 3.8 % ) in financing activities in february 2013 , we issued $ 250 million of two-year floating-rate u.s .dollar notes , and $ 400 million of ten-year 2.75% ( 2.75 % ) u.s .dollar notes .the proceeds from these notes will be used for general corporate purposes , including , together with cash on hand , repayment of the $ 750 million aggregate principal amount of our 4.25% ( 4.25 % ) u.s .dollar notes due march 2013 .the floating-rate notes bear interest equal to three-month libor plus 23 basis points , subject to quarterly reset .the notes contain customary covenants that limit the ability of kellogg company and its restricted subsidiaries ( as defined ) to incur certain liens or enter into certain sale and lease-back transactions , as well as a change of control provision .our net cash provided by financing activities was $ 1317 for 2012 , compared to net cash used in financing activities of $ 957 and $ 439 for 2011 and 2010 , respectively .the increase in cash provided from financing activities in 2012 compared to 2011 and 2010 , was primarily due to the issuance of debt related to the acquisition of pringles .total debt was $ 7.9 billion at year-end 2012 and $ 6.0 billion at year-end 2011 .in march 2012 , we entered into interest rate swaps on our $ 500 million five-year 1.875% ( 1.875 % ) fixed rate u.s .dollar notes due 2016 , $ 500 million ten-year 4.15% ( 4.15 % ) fixed rate u.s .dollar notes due 2019 and $ 500 million of our $ 750 million seven-year 4.45% ( 4.45 % ) fixed rate u.s .dollar notes due 2016 .the interest rate swaps effectively converted these notes from their fixed rates to floating rate obligations through maturity .in may 2012 , we issued $ 350 million of three-year 1.125% ( 1.125 % ) u.s .dollar notes , $ 400 million of five-year 1.75% ( 1.75 % ) u.s .dollar notes and $ 700 million of ten-year 3.125% ( 3.125 % ) u.s .dollar notes , resulting in aggregate net proceeds after debt discount of $ 1.442 billion .the proceeds of these notes were used for general corporate purposes , including financing a portion of the acquisition of pringles .in may 2012 , we issued cdn .$ 300 million of two-year 2.10% ( 2.10 % ) fixed rate canadian dollar notes , using the proceeds from these notes for general corporate purposes , which included repayment of

.dollar notes at maturity with commercial paper .in february 2011 , we entered into interest rate swaps on $ 200 million of our $ 750 million seven-year 4.45% ( 4.45 % ) fixed rate u.s .dollar notes due 2016 .the interest rate swaps effectively converted this portion of the notes from a fixed rate to a floating rate obligation through maturity .in april 2011 , we repaid $ 945 million ten-year

million for general corporate purposes and repayment of commercial paper .during 2011 , we entered into interest rate swaps with notional amounts totaling $ 400 million , which effectively converted

proceeds of $ 498 million for general corporate purposes and repayment of commercial paper .during 2012 , we entered into interest rate swaps which effectively converted these notes from a fixed rate to a floating rate obligation through maturity .in april 2010 , our board of directors approved a share repurchase program authorizing us to repurchase shares of our common stock amounting to $ 2.5 billion during 2010 through 2012 .this three year authorization replaced previous share buyback programs which had authorized stock repurchases of up to $ 1.1 billion for 2010 and $ 650 million for 2009 .under this program , we repurchased approximately 1 million , 15 million and 21 million shares of common stock for $ 63 million , $ 793 million and $ 1.1 billion during 2012 , 2011 and 2010 , respectively .in december 2012 , our board of directors approved a share repurchase program authorizing us to repurchase shares of our common stock amounting to $ 300 million during 2013 .we paid

3.4% ( 3.4 % ) in 2011 .in march 2011 , we entered into an unsecured four- year credit agreement which allows us to borrow , on a revolving credit basis , up to $ 2.0 billion .our long-term debt agreements contain customary covenants that limit kellogg company and some of its subsidiaries from incurring certain liens or from entering into certain sale and lease-back transactions .some agreements also contain change in control provisions .however , they do not contain acceleration of maturity clauses that are dependent on credit ratings .a change in our credit ratings could limit our access to the u.s .short-term debt market and/or increase the cost of refinancing long-term debt in the future .however , even under these circumstances , we would continue to have access to our four-year credit agreement , which expires in march 2015 .this source of liquidity is unused and available on an unsecured basis , although we do not currently plan to use it .capital and credit markets , including commercial paper markets , continued to experience instability and disruption as the u.s .and global economies underwent a period of extreme uncertainty .throughout this period of uncertainty , we continued to have access to the u.s. , european , and canadian commercial paper markets .our commercial paper and term debt credit ratings were not affected by the changes in the credit environment .we monitor the financial strength of our third-party financial institutions , including those that hold our cash and cash equivalents as well as those who serve as counterparties to our credit facilities , our derivative financial instruments , and other arrangements .we are in compliance with all covenants as of december 29 , 2012 .we continue to believe that we will be able to meet our interest and principal repayment obligations and maintain our debt covenants for the foreseeable future , while still meeting our operational needs , including the pursuit of selected bolt-on acquisitions .this will be accomplished through our strong cash flow , our short- term borrowings , and our maintenance of credit facilities on a global basis. .
