Retirement Benefit Plan |
Retirement Benefit Plan | 18. Retirement Benefit Plan Our 401(k) retirement plan provides for optional employee contributions up to the Internal Revenue Service limit and discretionary employer matching contributions. We make discretionary matching contributions to each participant’s account at a rate of (i) 100% of each participant’s first 1% of contributions plus (ii) 50% of each participant’s contributions up to the next 5% of eligible compensation. We made no discretionary matching contributions from July 1, 2009 through June 30, 2010, but began making them again effective on July 1, 2010. We recorded matching contributions of $7.6 million, $8.7 million and $3.9 million during 2012, 2011 and 2010, respectively.
