Employee Benefit Plans

Deferred Compensation Plans

The Firm maintains various non-qualified deferred compensation plans, pursuant to which eligible management and highly compensated key employees, as defined by IRS regulations, may elect to defer all or part of their compensation to later years. These amounts are classified in Accounts payable and other accrued liabilities if payable within the next year or in Other long-term liabilities if payable after the next year, upon retirement or termination of employment in the accompanying Unaudited Condensed Consolidated Balance Sheets. At March 31, 2017 and December 31, 2016, amounts included in Accounts payable and other accrued liabilities related to the deferred compensation plans totaled $3.7 million and $2.7 million, respectively. At March 31, 2017 and December 31, 2016, amounts included in Other long-term liabilities related to the deferred compensation plans totaled $27.0 million and $27.5 million, respectively.

Kforce maintains a Rabbi Trust and holds life insurance policies on certain individuals to assist in the funding of the deferred compensation liability. If necessary, employee distributions are funded through proceeds from the sale of assets held within our Rabbi Trust. The balance of the assets within the Rabbi Trust, including the cash surrender value of the Company-owned life insurance policies, was $28.6 million and $27.3 million as of March 31, 2017 and December 31, 2016, respectively, and is included in Other assets, net in the accompanying Unaudited Condensed Consolidated Balance Sheets.

Supplemental Executive Retirement Plan

Kforce maintains a Supplemental Executive Retirement Plan (the “SERP”) for the benefit of certain executive officers. The primary goals of the SERP are to create an additional wealth accumulation opportunity, restore lost qualified pension benefits due to government limitations and retain our covered executive officers. The SERP is a non-qualified benefit plan and does not include elective deferrals of covered executive officers’ compensation.

The following table presents the components of net periodic benefit cost (in thousands):



	Three Months Ended
	March 31,
	2017		2016
Service cost	$	80	$	328
Interest cost	134		113
Net periodic benefit cost	$	214	$	441

The service cost is recorded in Selling, general and administrative expenses and the interest cost is recorded in Other expense, net in the accompanying Unaudited Condensed Consolidated Statements of Operations and Comprehensive Income.

The projected benefit obligation as of March 31, 2017 and December 31, 2016 was $13.7 million and $13.4 million, respectively, and is recorded in Other long-term liabilities in the accompanying Unaudited Condensed Consolidated Balance Sheets. There is no requirement for Kforce to fund the SERP and, as a result, no contributions were made to the SERP during the three months ended March 31, 2017. Kforce does not currently anticipate funding the SERP during the year ended December 31, 2017.
