transaction. In addition, we entered into an agreement with DPS to include Dr Pepper and Diet Dr Pepper in our Coca-Cola Freestyle fountain dispensers in certain outlets throughout the United States. The Coca-Cola Freestyle agreement has a term of 20 years. 

The Company contributed $77 million to our pension plans during the year ended December 31, 2010. In 2011, we expect to contribute $800 million to various plans, of which approximately $750 million was contributed in the first quarter of 2011. Approximately half of the expected 2011 contributions will be allocated to our primary U.S. pension plans. Refer to Note 13 of Notes to Consolidated Financial Statements. 

The government in Venezuela has enacted certain monetary policies that restrict the ability of companies to pay dividends from retained earnings. As of December 31, 2010, cash held by our Venezuelan subsidiary accounted for approximately 2 percent of our consolidated cash and cash equivalents balance. In the first quarter of 2010 the Venezuelan government announced a currency devaluation and Venezuela was determined to be a hyperinflationary economy. As a result, our local subsidiary was required to use the U.S. dollar as its functional currency, and we recorded a net remeasurement loss of $103 million during the first quarter of 2010 in the line item other income (loss) — net in our consolidated statement of income. As of December 31, 2010, our Venezuelan subsidiary held monetary assets of approximately $200 million. 

In addition to the foreign currency exchange exposure related to our Venezuelan subsidiary's net assets, we also sell concentrate to our bottling partner in Venezuela from outside the country. These sales are denominated in U.S. dollars. Some of our concentrate sales were approved by the CADIVI to receive the official rate for essential goods of 2.6 bolivars per U.S. dollar prior to the elimination of the official rate for essential goods in December 2010. Prior to the elimination of the official rate for essential goods, our bottling partner in Venezuela was able to convert bolivars to U.S. dollars to settle our receivables related to sales approved by the CADIVI. Therefore, as of December 31, 2010, our receivable balance related to concentrate sales that had been approved by the CADIVI was not significant. If we are unable to utilize a government-approved exchange rate mechanism for future concentrate sales to our bottling partner in Venezuela, the amount of receivables related to these sales will increase. 

In addition to the Company's cash balances and commercial paper program, we also maintain $4,850 million in lines of credit for general corporate purposes, including commercial paper backup, of which approximately $4,597 million was unused and available as of December 31, 2010. Refer to Note 10 of Notes to Consolidated Financial Statements. These backup lines of credit expire at various times from 2011 through 2012. These credit facilities are subject to normal banking terms and conditions. Some of the financial arrangements require compensating balances, none of which is presently significant to our Company. We have evaluated the financial stability of
