If the market value of the Company's net commodity and currency derivative positions with certain counterparties exceeds the applicable threshold, if any, the counterparty is required to post margin by transferring cash collateral in excess of the threshold to the Company. Conversely, if the market value of these net derivative positions falls below a specified threshold, the Company is required to post margin by transferring cash collateral below the threshold to certain counterparties. At both </font><font style="font-family:inherit;font-size:10pt;">December 31, 2014</font><font style="font-family:inherit;font-size:10pt;"> and </font><font style="font-family:inherit;font-size:10pt;">December 31, 2013</font><font style="font-family:inherit;font-size:10pt;">, the Company had </font><font style="font-family:inherit;font-size:10pt;">no</font><font style="font-family:inherit;font-size:10pt;"> margin deposits with or from its counterparties.</font></div><div style="line-height:120%;padding-top:12px;text-align:left;text-indent:20px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The Company is exposed to credit loss in the event of nonperformance by counterparties on derivative contracts used in hedging activities as well as failure of counterparties to return cash collateral previously transferred to the counterparties. The counterparties to the Company's derivative contracts are major financial institutions and the Company does not expect nonperformance by any of its counterparties.</font></div><div style="line-height:120%;padding-top:12px;text-align:left;text-indent:20px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The Company places its cash in commercial paper, savings accounts, demand notes and money market funds. Such money market funds are with high credit quality financial institutions which invest primarily in commercial paper and time deposits of prime quality, short-term repurchase agreements and U.S. government agency notes.</font></div><div style="line-height:120%;padding-top:12px;text-align:left;text-indent:20px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">For information about concentration risks concerning customers and suppliers, see </font><font style="font-family:inherit;font-size:10pt;">Note 13</font><font style="font-family:inherit;font-size:10pt;">.</font></div></div>

Uncertainties with respect to such estimates and assumptions are inherent in the preparation of the Company’s consolidated financial statements; accordingly, it is possible that the actual results could differ from these estimates and assumptions, which could have a material effect on the reported amounts of the Company’s consolidated financial position and results of operations.</font></div></div>
