Benefit Plans	(13) Benefit Plans As of December 31, 2014, CVR sponsored two defined-contribution 401(k) plans (the "Plans") for all employees. Participants in the Plans may elect to contribute up to 100% of their annual salaries and up to 100% of their annual income sharing. CVR matches up to 100% of the first 6% of the participant's contribution for the nonunion and union plans. All Plans are administered by CVR and contributions for the union plan were determined in accordance with provisions of negotiated labor contracts. Participants in both Plans are immediately vested in their individual contributions. Both Plans have a three-year vesting schedule for CVR's matching funds and contain a provision to count service with any predecessor organization. CVR's contributions under the Plans were approximately $6.6 million, $6.1 million and $4.5 million for the years ended December 31, 2014, 2013 and 2012, respectively.
