Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Polaris is subject to product liability claims in the normal course of business. The Company carries excess insurance coverage for catastrophic product liability claims. Polaris self-insures product liability claims before the policy date and up to the purchased catastrophic insurance coverage after the policy date. The estimated costs resulting from any losses are charged to operating expenses when it is probable a loss has been incurred and the amount of the loss is reasonably estimable. The Company utilizes historical trends and actuarial analysis tools, along with an analysis of current claims, to assist in determining the appropriate loss reserve levels. At September 30, 2018, the Company had an accrual of $55,320,000 for the probable payment of pending claims related to continuing product liability litigation associated with Polaris products. This accrual is included as a component of other accrued expenses in the accompanying consolidated balance sheets. Polaris is also a defendant in lawsuits and subject to other claims arising in the normal course of business, including matters related to intellectual property, commercial matters, product liability claims, and putative class action lawsuits. As of September 30, 2018, the Company is party to two putative class actions pending against Polaris in the United States, alleging that certain Polaris products caused personal injury, economic losses, and other damages resulting from unresolved fire hazards and excessive heat hazards. The Company is unable to provide an evaluation of the likelihood that a loss will be incurred or an estimate of the range of possible loss. In the opinion of management, it is unlikely that any legal proceedings pending against or involving Polaris will have a material adverse effect on Polaris’ financial position, results of operations, or cash flows. However, in many of these matters, it is inherently difficult to determine whether a loss is probable or reasonably possible or to estimate the size or range of the possible loss given the variety and potential outcomes of actual and potential claims, the uncertainty of future rulings, the behavior or incentives of adverse parties, and other factors outside of the control of the Company. Accordingly, the Company’s loss reserve may change from time to time, and actual losses could exceed the amounts accrued by an amount that could be material to our consolidated financial position, results of operations, or cash flows in any particular reporting period. In the normal course of business, the Company’s products are subject to extensive laws and regulations relating to safety, environmental and other regulations promulgated by the United States federal government and individual states, as well as international regulatory authorities. Failure to comply with applicable regulations could result in fines, penalties or other costs.
