Contingencies Certain conditions may exist which could result in a loss, but which will only be resolved when future events occur. The Company, in consultation with its legal counsel, assesses such contingent liabilities, and such assessments inherently involve an exercise of judgment. If the assessment of a contingency indicates that it is probable that a loss has been incurred, the Company accrues for such contingent loss when it can be reasonably estimated. If the assessment indicates that a potentially material loss contingency is not probable but reasonably estimable, or is probable but cannot be estimated, the nature of the contingent liability, together with an estimate of the range of possible loss if determinable and material, is disclosed. If the assessment of a contingency deemed to be both probable and reasonably estimable involves a range of possible losses, the amount within the range that appears at the time to be a better estimate than any other amount within the range would be accrued. When no amount within the range is a better estimate than any other amount, the minimum amount in the range is accrued even though the minimum amount in the range is not necessarily the amount of loss that will be ultimately determined. Estimates of potential legal fees and other directly related costs associated with contingencies are not accrued but rather are expensed as incurred. Except as disclosed below under "Legal Proceedings," management does not believe there are any pending claims (asserted or unasserted) at September 30, 2018 (unaudited) or June 30, 2018 that may have a material adverse impact on the Company’s financial condition, results of operations or cash flows. Legal Proceedings On August 26, 2016, Wizard Lake Marine Inc. and Wizard Lake Marine (B.C.) Inc., collectively “Wizard Lake”, a former dealer of the Company’s, initiated a lawsuit against the Company in the Court of Queen’s Bench of Alberta, Canada seeking monetary damages. The suit alleges breach of contract, wrongful termination, misrepresentation, breach of duty of good faith, and intentional interference. Wizard Lake is asking for damages exceeding $5,000. The Company denies any liability arising from the causes of action alleged by Wizard Lake and is vigorously defending the lawsuit, including commencing a counterclaim against Wizard Lake. The lawsuit is early in the discovery phase. On January 21, 2015, Cobalt, a wholly owned indirect subsidiary of the Company, filed a patent infringement lawsuit against the Brunswick Corporation and its subsidiary Sea Ray Boats, Inc. alleging that certain of the Sea Ray's branded boats infringed upon Cobalt's patented submersible swim step technology (U.S. Patent No. 8,375,880). On October 31, 2017, the US District Court in the Eastern District of Virginia entered an amended judgment on the jury verdict in favor of Cobalt.

Repurchase Commitments

In connection with its dealers’ wholesale floor plan financing of boats, the Company has entered into repurchase agreements with various lending institutions. The reserve methodology used to record an estimated expense and loss reserve in each accounting period is based upon an analysis of likely repurchases based on current field inventory and likelihood of repurchase. Subsequent to the inception of the repurchase commitment, the Company evaluates the likelihood of repurchase and adjusts the estimated loss reserve accordingly. This potential loss reserve is presented in accrued liabilities in the accompanying unaudited condensed consolidated balance sheet. If the Company were obligated to repurchase a significant number of units under any repurchase agreement, its business, operating results and financial condition could be adversely affected. The total amount financed under the floor financing programs with repurchase obligations was $136,520 and $163,626 as of September 30, 2018 and June 30, 2018, respectively.

Repurchases and subsequent sales are recorded as a revenue transaction. The net difference between the repurchase price and the resale price is recorded against the loss reserve and presented in cost of sales in the accompanying unaudited condensed consolidated statements of operations and comprehensive income. The Company did not carry a reserve for repurchases as of September 30, 2018 and June 30, 2018.

The Company has collateralized receivables financing arrangements with a third-party floor plan financing provider for European dealers.
