Commitments to Provide Marketing Allowances under Long-Term Customer Contracts

The Company has or is renegotiating long-term agreements with many of its major customers. Under these agreements, which in most cases have initial terms of at least four years, the Company is designated as the exclusive or primary supplier for specified categories of the Company’s products. Because of the very competitive nature of the market and the limited number of customers for these products, the Company’s customers have sought and obtained price concessions, significant marketing allowances, and more favorable delivery and payment terms in consideration for the Company’s designation as a customer’s exclusive or primary supplier. These incentives differ from contract to contract and can include (i) the issuance of a specified amount of credits against receivables in accordance with a schedule set forth in the relevant contract, (ii) support for a particular customer’s research or marketing efforts provided on a scheduled basis, (iii) discounts granted in connection with each individual shipment of product, and (iv) other marketing, research, store expansion or product development support. These contracts typically require that the Company meet ongoing performance standards. The Company’s contracts with its customers expire at various dates through December 2024. While these longer-term agreements strengthen the Company’s customer relationships, the increased demand for the Company’s products often requires that the Company increase its inventories and personnel. Customer demands that the Company purchase their Remanufactured Core inventory also require the use of the Company’s working capital.

The marketing and other allowances the Company typically grants its customers in connection with its new or expanded customer relationships adversely impact the near-term revenues, profitability, and associated cash flows from these arrangements. Such allowances include sales incentives and concessions and typically consist of: (i) allowances which may only be applied against future purchases and are recorded as a reduction to revenues in accordance with a schedule set forth in the long-term contract, (ii) allowances related to a single exchange of product that are recorded as a reduction of revenues at the time the related revenues are recorded or when such incentives are offered, and (iii) amortization of core premiums paid to customers generally in connection with new business.

The following summarizes the breakout of allowances discussed above, recorded as a reduction to revenues:

	Years Ended March 31,
	2019		2018		2017
			(As Adjusted)		(As Adjusted)
Allowances incurred under long-term customer contracts	$	29,612,000	$	24,829,000	$	23,684,000
Allowances related to a single exchange of product		92,588,000		79,851,000		67,870,000
Amortization of core premiums paid to customers		4,127,000		3,588,000		3,232,000
Total customer allowances recorded as a reduction of revenues	$	126,327,000	$	108,268,000	$	94,786,000
