Director and Employee Benefit Plans	DIRECTOR AND EMPLOYEE BENEFIT PLANS Directors and Officers Retirement Plan We provide eligible executives and directors an opportunity to defer to a future date the receipt of base and bonus compensation for services as well as director’s fees through the 2005 Deferred Compensation Plan (the "Deferred Plan"). Our matching contribution on base compensation deferral of executives equals the matching contribution of our profit-sharing plan with certain limits. Our directors may elect to invest the deferred director fee compensation into our common stock within the Deferred Plan. Investments in our common stock are credited as hypothetical shares of common stock based on the market price of the stock at the time the compensation was earned.

Other Retirement Plans We have a profit-sharing plan that covers all employees not otherwise participating in an associated profit-sharing plan, with three months or more of service. We will match contributions made by employees up to 3% of the employee’s annual compensation and match at 50% contributions made by the employee up to an additional 2% of compensation with certain limits. We may also contribute a discretionary amount determined annually by the Board of Directors as well as a year-end discretionary match not to exceed 4% of compensation. Our cash contribution to the plan was approximately $4.0 million in 2016, $3.4 million in 2015, and $2.5 million in 2014. We are a member of a noncontributory defined benefit multi-employer retirement plan for all members of the Pari-mutuel Clerk’s Union of Kentucky and several other collectively bargained retirement plans, which are administered by unions. Cash contributions are made in accordance with negotiated labor contracts. Retirement plan expense was $0.6 million in 2016, $0.6 million in 2015 and $0.7 million in 2014. Our policy is to fund this expense as accrued, and we currently estimate that future contributions to these plans will not increase significantly from prior years.
