In September 1999, the Sports Authority of the County of Wilson (Tennessee) issued $25,900,000 in Variable Rate Tax Exempt Infrastructure Revenue Bonds, Series 1999, to acquire, construct and develop certain public infrastructure improvements which benefit Nashville Superspeedway, of which $14,400,000 was outstanding at December 31, 2018.

During 2018, we paid $984,000 into the sales and incremental property tax fund and $1,411,000 was deducted from the fund for debt service.

We lease the facility on a short term basis to third parties from time to time. In 2011 we recorded a $2,250,000 provision for contingent obligation reflecting the present value of the estimated portion of the revenue bonds debt service that may not be covered by the projected sales and incremental property taxes from the facility. Due to changing interest rates, the provision for contingent obligation increased by $424,000, $158,000 and $75,000 in 2018, 2017 and 2016, respectively, and is $2,384,000 at December 31, 2018. An increase in the bonds’ interest rates would result in an increase in the portion of debt service not covered by applicable taxes and therefore an increase in our liability. We have employment, severance and noncompete agreements with certain of our officers and directors under which certain change of control, severance and noncompete payments and benefits might become payable in the event of a change in our control, defined to include a tender offer or the closing of a merger or similar corporate transactions. In the event of such a change in control and the subsequent termination of employment of all employees covered under these agreements, we estimate that the maximum contingent liability would range from $7,300,000 to $9,100,000 depending on the tax treatment of the payments. To the extent that any of the potential payments or benefits due under the agreements constitute an excess “parachute payment” under the Internal Revenue Code and result in the imposition of an excise tax, each agreement requires that we pay the amount of such excise tax plus any additional amounts necessary to place the officer or director in the same after-tax position as he would have been had no excise tax been imposed. We estimate that the tax gross ups that could be paid under the agreements in the event the agreements were triggered due to a change of control could be between $1,000,000 and $2,800,000 and these amounts have been included in the maximum contingent liability disclosed above. This maximum tax gross up figure assumes that none of the payments made after the hypothetical change in control would be characterized as reasonable compensation for services rendered. Each agreement with an executive officer provides that fifty percent of the monthly amount paid during the term is paid in consideration of the executive officer’s non-compete covenants. The exclusion of these amounts would reduce the calculated amount of excess parachute payments subject to tax. We are unable to conclude whether the Internal Revenue Service would characterize all or some of these non-compete payments as reasonable compensation for services rendered. We are also a party to ordinary routine litigation incidental to our business. Management does not believe that the resolution of any of these matters is likely to have a material adverse effect on our results of operations, financial position or cash flows.
