EMPLOYEE BENEFIT PLANS
 
We sponsor a defined contribution plan covering substantially all of our U.S. employees. Although we may make discretionary contributions for the benefit of employees under this plan, such matching contributions have been suspended since 2010. In 2014, 2013 and 2012, amounts expensed included both mandatory and discretionary contributions in certain countries outside the United States and were approximately $2.3 million, $2.1 million and $1.8 million, respectively.
