EMPLOYEE BENEFIT PLANS

Employee Benefit Plans

The Company has a Section 401(k) plan that covers substantially all U.S. employees. The 401(k) plan allows employees to make contributions up to a specified percentage of their compensation. The Company may, upon resolution by the Company’s board of directors, make discretionary contributions to the plan. The Company’s contributions to the plan totaled $2.3 million, $2.2 million and $2.2 million in 2015, 2014 and 2013, respectively.

In addition, the Company has various retirement and post-employment plans covering certain international employees. Certain of the plans allow the Company to match employee contributions up to a specified percentage as defined by the plans. The Company’s contributions to these plans totaled $2.2 million, $2.0 million and $1.2 million in 2015, 2014 and 2013, respectively.

Deferred Compensation Plans

The Company maintains a nonqualified deferred compensation plan (the “Deferred Plan”). The Deferred Plan covers senior management and members of the Board. In November 2013, the Board determined to indefinitely suspend the plan, and not offer participants the opportunity to participate in the Deferred Plan as of 2014. The benefits payable under the Deferred Plan represent an unfunded and unsecured contractual obligation of the Company to pay the value of the deferred compensation in the future, adjusted to reflect deemed investment performance. Payouts are generally made upon termination of employment with the Company. The assets of the deferred plan, as well as the corresponding obligations, were approximately $0.6 million and $1.2 million at December 31, 2015 and 2014, respectively, and were recorded in “other current assets” and “accrued compensation and benefits” at those dates.

In connection with the acquisition of a business in 2010, the Company assumed the assets and liabilities of a deferred compensation arrangement for a single individual in Germany. The arrangement represents a contractual obligation of the Company to pay a fixed euro amount for a period specified in the contract. In connection with the acquisition of Orad, the Company assumed the assets and liabilities of a deferred compensation arrangement for employees in Israel. At December 31, 2015 and 2014, the Company’s assets and liabilities related to the arrangements consisted of assets recorded in “other long-term assets” of $3.0 million at December 31, 2015 and $0.6 million at December 31, 2014, representing the value of related insurance contracts and investments, and liabilities recorded as “long-term liabilities” of $7.3 million at December 31, 2015 and $4.7 million at December 31, 2014, respectively, representing the fair value of the estimated benefits to be paid under the
