Personal Injury Actions and Other — Product and general liability claims are made against the Company from time to time in the ordinary course of business. The Company is generally self-insured for future claims up to $5.0 million per claim. Accordingly, a reserve is maintained for the estimated costs of such claims. At September 30, 2019 and 2018, the estimated net liabilities for product and general liability claims totaled $36.2 million and $36.0 million, respectively. There is inherent uncertainty as to the eventual resolution of unsettled claims. Management, however, believes that any losses in excess of established reserves will not have a material effect on the Company’s financial condition, results of operations or cash flows.

Market Risks — The Company was contingently liable under bid, performance and specialty bonds totaling $552.2 million and $599.2 million at September 30, 2019 and 2018, respectively. Open standby letters of credit issued by the Company’s banks in favor of third parties totaled $63.7 million and $91.1 million at September 30, 2019 and 2018, respectively.

Other Matters — The Company is subject to other environmental matters and legal proceedings and claims, including patent, antitrust, product liability, warranty and state dealership regulation compliance proceedings that arise in the ordinary course of business. Although the final results of all such matters and claims cannot be predicted with certainty, management believes that the ultimate resolution of all such matters and claims will not have a material effect on the Company’s financial condition, results of operations or cash flows. Actual results could vary, among other things, due to the uncertainties involved in litigation.

At September 30, 2019, approximately 25% of the Company’s workforce was covered under collective bargaining agreements.

The Company derived a significant portion of its revenue from the DoD, as follows (in millions):

	Fiscal Year Ended September 30,
	2019		2018		2017
DoD	$	2,006.9	$	1,648.4	$	1,314.6
Foreign military sales		27.7		28.0		32.1
Total DoD sales	$	2,034.6	$	1,676.4	$	1,346.7

No other customer represented more than 10% of sales for fiscal 2019, 2018 or 2017.

Certain risks are inherent in doing business with the DoD, including technological changes and changes in levels of defense spending. All DoD contracts contain a provision that they may be terminated at any time at the convenience of the U.S. government. In such an event, the Company is entitled to recover allowable costs plus a reasonable profit earned to the date of termination.

Because the Company is a relatively large defense contractor, the Company’s U.S. government contract operations are subject to extensive annual audit processes and to U.S. government investigations of business practices and cost classifications from which legal or administrative proceedings can result. Based on U.S. government procurement regulations, under certain circumstances the Company could be fined, as well as suspended or debarred from U.S. government contracting. During a suspension or debarment, the Company would also be prohibited from selling equipment or services to customers that depend on loans or financial commitments from the Export-Import Bank, Overseas Private Investment Corporation and similar U.S. government agencies.

The Company was one of several bidders on a large, multi-year military truck solicitation for the Canadian government. The Company’s bid was not selected, and the Company subsequently submitted a legal challenge of that conclusion. In May 2016, the Canadian International Trade Tribunal (the “Tribunal”) ruled in the Company’s favor in connection with that challenge. In December 2017, the Tribunal issued its Order and Reasons (the “Order”) outlining the compensation to which the Company is entitled as a result of the challenge. Under the Order, the Tribunal recommended that the Company be awarded a fixed payment for lost profits of approximately $25.3 million Canadian dollars plus additional compensation on any potential future option exercises if and when exercised by Canada. In August 2018, the Company reached a settlement with the Canadian government. The Company recorded a $19.0 million U.S. dollar reduction of selling, general and administrative expenses in fiscal 2018 in connection with the settlement.

The Company recognized a $6.6 million gain during fiscal 2018 upon receipt of proceeds for a claim under its business interruption insurance. The claim was primarily for loss profits due to an accident that occurred at one of the commercial segment’s facilities in January 2017. The gain has been recognized as a reduction of cost of sales.
