Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis Certain financial instruments are measured at fair value on a nonrecurring basis. These assets primarily include goodwill, intangible assets, property, plant and equipment, and right-of-use lease assets. These assets were originally recognized at amounts equal to the fair value determined at date of acquisition or purchase. If certain triggering events occur, or if an annual impairment test is required, we will evaluate the non-financial asset for impairment. If an impairment has occurred, the asset will be written down to its current estimated fair value. No impairments were recorded for non-financial assets in the nine months ended May 27, 2023 or May 28, 2022. Assets and Liabilities Not Measured at Fair Value Certain financial instruments are not measured at fair value but are recorded at carrying amounts approximating fair value based on their short-term nature. These financial instruments include cash and cash equivalents, receivables, accounts payable, other payables, and long-term debt. If these instruments were measured at fair value in the financial statements, they would be classified as Level 1 in the fair value hierarchy. The fair value of our long-term debt was determined using current quoted prices in active markets for our publicly traded debt obligations, which is classified as Level 1 in the fair value hierarchy. See Note 9 in the Notes to Consolidated Financial Statements included in Item 1 of Part I of this Quarterly Report on Form 10-Q for the fair value of our long-term debt.
Repurchase Commitments	Generally, manufacturers in the same industries as us enter into repurchase agreements with lending institutions which have provided wholesale floorplan financing to dealers. Most dealers are financed on a "floorplan" basis under which a bank or finance company lends the dealer all, or substantially all, of the purchase price, collateralized by a security interest in the units purchased. Our repurchase agreements generally provide that, in the event of default by the dealer on the agreement to pay the lending institution, we will repurchase the financed merchandise. The terms of these agreements, which generally can last up to 24 months, provide that our liability will be the lesser of remaining principal owed by the dealer to the lending institution, or dealer invoice less periodic reductions based on the time since the date of the original invoice. Our liability cannot exceed 100% of the dealer invoice. In certain instances, we also repurchase inventory from dealers due to state law or regulatory requirements that govern voluntary or involuntary relationship terminations. Although laws vary from state to state, some states have laws in place that require manufacturers of recreational vehicles or boats to repurchase current inventory if a dealership exits the business. The total contingent liability on all of our repurchase agreements was approximately $2,069.8 million and $1,783.7 million at May 27, 2023 and August 27, 2022, respectively. Our loss reserve for repurchase commitments contains uncertainties because the calculation requires management to make assumptions and apply judgment regarding a number of factors. Our risk of loss related to these repurchase commitments is significantly reduced by the potential resale value of any products that are subject to repurchase and is spread over numerous dealers and lenders. The aggregate contingent liability related to our repurchase agreements represents all financed dealer inventory at the period-end reporting date subject to a repurchase agreement, net of the greater of periodic reductions per the agreement or dealer principal payments. Based on these repurchase agreements and our historical loss experience, an associated loss reserve is established which is included in other current liabilities on the Consolidated Balance Sheets. Our repurchase accrual was $1.3 million and $1.4 million at May 27, 2023 and August 27, 2022, respectively. Repurchase risk is affected by the credit worthiness of our dealer network. We do not believe there is a reasonable likelihood that there will be a material change in the estimates or assumptions used to establish the loss reserve for repurchase commitments.
Revenue	We do not have material contract assets or liabilities. Allowances for uncollectible receivables are established based on historical collection trends, write-off history, consideration of current conditions and expectations for future economic conditions.
