Employee Benefit Programs
Employee Deferred Compensation Plan—In 2003, the Company adopted a deferred compensation plan that permits key employees and other members of management not eligible to participate in the Employee Defined Contribution Plan to defer portions of their compensation. Under this plan, eligible team members may elect to defer up to 75% of their base salary and up to 100% of variable compensation and commissions each plan year. The Company may make matching contributions in an amount determined by the board of directors. In 2016, the board of directors authorized matching contributions equal to 50% of the first 4% of compensation that is deferred by the participant, an increase from the previous matching contributions equal to 25% of the first 4% of compensation deferred by the participant. The Company recognized an immaterial matching contribution expense in 2017, 2016, and 2015.
The assets of the deferred compensation plan are held in a rabbi trust, where they are invested in certain mutual funds that cover an investment spectrum ranging from equities to money market instruments and are available to satisfy the claims of the Company’s creditors in the event of bankruptcy or insolvency. These mutual funds have published market prices and are reported at fair value. See Note 9, Fair Value Measurements. Changes in the market value of the investments held in the trust result in the recognition of a corresponding gain or loss reported in Interest income and other, net in the consolidated statements of operations. A corresponding change in the liability associated with the deferred compensation plan results in an offsetting deferred compensation expense, or reduction of expense, reported in Selling, general, and administrative expenses in the consolidated statements of operations. The Company recognized deferred compensation expense of $1.0 million in 2017, $0.6 million in 2016, and an immaterial amount in 2015. As of December 31, 2017 and December 25, 2016, $9.3 million and $9.2 million of deferred compensation assets is included in Other assets, net and $9.3 million and $9.2 million of deferred compensation plan liability is included in Other non-current liabilities in the accompanying consolidated balance sheets.
Employee Stock Purchase Plan—In July 2017, the Company adopted the Amended and Restated Employee Stock Purchase Plan (the “New Plan”), which replaced the previous Employee Stock Purchase Plan (the “Prior Plan”). The New Plan authorized 100,000 shares of the Company’s common stock for issuance. Under the New Plan, eligible team members may voluntarily contribute up to 15% of their salary, subject to limitations, to purchase common stock at a price equal to 85% of the fair market value of a share of the Company’s common stock on the first day of each offering period or 85% of the fair market value of a share of the Company’s common stock on the last day of each offering period, whichever amount is less. In general, all of the Company’s officers and team members who have been employed by the Company for at least one year and who are regularly scheduled to work more than 20 hours per week are eligible to participate in this plan which operates in successive six month periods commencing on each January 1 and July 1 of each fiscal year. During 2017, the Company issued 17,294 shares under the Prior Plan. The Company has issued a total of 7,607 shares under the New Plan, and a total of 92,393 shares remain available for future issuance.
For 2017, in accordance with the guidance for accounting for stock compensation, the Company estimated the fair value of the awards granted pursuant to the stock purchase plan using the Black-Scholes multiple-option pricing model. The average assumptions used in the model included a 1.05% risk-free interest rate; 0.5 year expected life; expected volatility of 37.96%; and a 0% dividend yield. The weighted average fair value per share at grant date was $11.16. For 2016, the average assumptions used in the model included a 0.55% risk-free interest rate, 0.5 year expected life, expected volatility of 37.64%, and a 0% dividend yield. The weighted average fair value per share at grant date was $9.29. The Company recognized $0.2 million of compensation expense related to this plan in each of fiscal years 2017, 2016, and 2015.
Employee Defined Contribution Plan—The Company maintains a 401(k) Savings Plan (“401K Plan”) which covers eligible team members who have satisfied the service requirements and reached 21 years of age. The 401K Plan, which qualifies under Section 401(k) of the Internal Revenue Code, allows team members to defer specified percentages of their compensation on a pre-tax basis. The Company may make matching contributions in an amount determined by the board of directors. In addition, the Company may contribute each period, at its discretion, an additional amount from profits. In 2016, the board of directors authorized matching contributions equal to 50% of the first 4% of compensation that is deferred by the participant, an increase from the Company’s previous matching contributions equal to 25% of the first 4% of compensation deferred by the participant. The Company recognized matching contribution expense of $0.7 million in 2017, $0.6 million in 2016, and $0.3 million in 2015.
