Text: 62 general mills amounts recorded in accumulated other comprehensive loss unrealized losses from interest rate cash flow hedges recorded in aoci as of may 27 , 2012 , totaled $ 73.6 million after tax . these deferred losses are primarily related to interest rate swaps that we entered into in contemplation of future borrowings and other financ- ing requirements and that are being reclassified into net interest over the lives of the hedged forecasted transac- tions . unrealized losses from foreign currency cash flow hedges recorded in aoci as of may 27 , 2012 , were $ 1.7 million after-tax . the net amount of pre-tax gains and losses in aoci as of may 27 , 2012 , that we expect to be reclassified into net earnings within the next 12 months is $ 14.0 million of expense . credit-risk-related contingent features certain of our derivative instruments contain provisions that require us to maintain an investment grade credit rating on our debt from each of the major credit rat- ing agencies . if our debt were to fall below investment grade , the counterparties to the derivative instruments could request full collateralization on derivative instru- ments in net liability positions . the aggregate fair value of all derivative instruments with credit-risk-related contingent features that were in a liability position on may 27 , 2012 , was $ 19.9 million . we have posted col- lateral of $ 4.3 million in the normal course of business associated with these contracts . if the credit-risk-related contingent features underlying these agreements had been triggered on may 27 , 2012 , we would have been required to post an additional $ 15.6 million of collateral to counterparties . concentrations of credit and counterparty credit risk during fiscal 2012 , wal-mart stores , inc . and its affili- ates ( wal-mart ) accounted for 22 percent of our con- solidated net sales and 30 percent of our net sales in the u.s . retail segment . no other customer accounted for 10 percent or more of our consolidated net sales . wal- mart also represented 6 percent of our net sales in the international segment and 7 percent of our net sales in the bakeries and foodservice segment . as of may 27 , 2012 , wal-mart accounted for 26 percent of our u.s . retail receivables , 5 percent of our international receiv- ables , and 9 percent of our bakeries and foodservice receivables . the five largest customers in our u.s . retail segment accounted for 54 percent of its fiscal 2012 net sales , the five largest customers in our international segment accounted for 26 percent of its fiscal 2012 net sales , and the five largest customers in our bakeries and foodservice segment accounted for 46 percent of its fis- cal 2012 net sales . we enter into interest rate , foreign exchange , and cer- tain commodity and equity derivatives , primarily with a diversified group of highly rated counterparties . we continually monitor our positions and the credit rat- ings of the counterparties involved and , by policy , limit the amount of credit exposure to any one party . these transactions may expose us to potential losses due to the risk of nonperformance by these counterparties ; however , we have not incurred a material loss . we also enter into commodity futures transactions through vari- ous regulated exchanges . the amount of loss due to the credit risk of the coun- terparties , should the counterparties fail to perform according to the terms of the contracts , is $ 19.5 million against which we do not hold collateral . under the terms of master swap agreements , some of our transactions require collateral or other security to support financial instruments subject to threshold levels of exposure and counterparty credit risk . collateral assets are either cash or u.s . treasury instruments and are held in a trust account that we may access if the counterparty defaults . note 8 . debt notes payable the components of notes payable and their respective weighted-average interest rates at the end of the periods were as follows: . <table class='wikitable'><tr><td>1</td><td>in millions</td><td>may 27 2012 notes payable</td><td>may 27 2012 weighted- average interest rate</td><td>may 27 2012 notespayable</td><td>weighted-averageinterest rate</td></tr><tr><td>2</td><td>u.s . commercial paper</td><td>$ 412.0</td><td>0.2% ( 0.2 % )</td><td>$ 192.5</td><td>0.2% ( 0.2 % )</td></tr><tr><td>3</td><td>financial institutions</td><td>114.5</td><td>10.0</td><td>118.8</td><td>11.5</td></tr><tr><td>4</td><td>total</td><td>$ 526.5</td><td>2.4% ( 2.4 % )</td><td>$ 311.3</td><td>4.5% ( 4.5 % )</td></tr></table> to ensure availability of funds , we maintain bank credit lines sufficient to cover our outstanding short- term borrowings . commercial paper is a continuing source of short-term financing . we have commercial paper programs available to us in the united states and europe . in april 2012 , we entered into fee-paid commit- ted credit lines , consisting of a $ 1.0 billion facility sched- uled to expire in april 2015 and a $ 1.7 billion facility .
