liquidity and capital resources as of december 31 , 2011 , our principal sources of liquidity included cash , cash equivalents , our receivables securitization facility , and our revolving credit facility , as well as the availability of commercial paper and other sources of financing through the capital markets .
we had $ 1.8 billion of committed credit available under our credit facility , with no borrowings outstanding as of december 31 , 2011 .
we did not make any borrowings under this facility during 2011 .
the value of the outstanding undivided interest held by investors under the receivables securitization facility was $ 100 million as of december 31 , 2011 , and is included in our consolidated statements of financial position as debt due after one year .
the receivables securitization facility obligates us to maintain an investment grade bond rating .
if our bond rating were to deteriorate , it could have an adverse impact on our liquidity .
access to commercial paper as well as other capital market financings is dependent on market conditions .
deterioration of our operating results or financial condition due to internal or external factors could negatively impact our ability to access capital markets as a source of liquidity .
access to liquidity through the capital markets is also dependent on our financial stability .
we expect that we will continue to have access to liquidity by issuing bonds to public or private investors based on our assessment of the current condition of the credit markets .
at december 31 , 2011 and 2010 , we had a working capital surplus .
this reflects a strong cash position , which provides enhanced liquidity in an uncertain economic environment .
in addition , we believe we have adequate access to capital markets to meet cash requirements , and we have sufficient financial capacity to satisfy our current liabilities .

operating activities higher net income and lower cash income tax payments in 2011 increased cash provided by operating activities compared to 2010 .
the tax relief , unemployment insurance reauthorization , and job creation act of 2010 , enacted in december 2010 , provided for 100% ( 100 % ) bonus depreciation for qualified investments made during 2011 , and 50% ( 50 % ) bonus depreciation for qualified investments made during 2012 .
as a result of the act , the company deferred a substantial portion of its 2011 income tax expense .
this deferral decreased 2011 income tax payments , thereby contributing to the positive operating cash flow .
in future years , however , additional cash will be used to pay income taxes that were previously deferred .
in addition , the adoption of a new accounting standard in january of 2010 changed the accounting treatment for our receivables securitization facility from a sale of undivided interests ( recorded as an operating activity ) to a secured borrowing ( recorded as a financing activity ) , which decreased cash provided by operating activities by $ 400 million in 2010 .
higher net income in 2010 increased cash provided by operating activities compared to 2009 .
investing activities higher capital investments partially offset by higher proceeds from asset sales in 2011 drove the increase in cash used in investing activities compared to 2010 .
higher capital investments and lower proceeds from asset sales in 2010 drove the increase in cash used in investing activities compared to 2009. .
