BASIS OF PRESENTATION
BASIS OF PRESENTATION	A. BASIS OF PRESENTATION The accompanying unaudited interim consolidated condensed financial statements (the “Financial Statements”) include our accounts and those of our wholly-owned and majority-owned subsidiaries and partnerships, and have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Accordingly, the Financial Statements do not include all the information and footnotes normally included in the annual consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States. All intercompany transactions and balances have been eliminated. Certain prior year amounts have been reclassified to conform to the current year presentation. In our opinion, the Financial Statements contain all material adjustments necessary to present fairly our consolidated financial position, results of operations and cash flows for the interim periods presented. All such adjustments are of a normal recurring nature. These Financial Statements should be read in conjunction with the annual consolidated financial statements, and footnotes thereto, included in our Annual Report to Shareholders on Form 10-K for the fiscal year ended December 26, 2020. Seasonality has a significant impact on our working capital from March to August, which historically results in negative or modest cash flows from operations in our first and second quarters. Conversely, we experience a substantial decrease in working capital from September to February which typically results in significant cash flow from operations in our third and fourth quarters. For comparative purposes, we have included the June 27, 2020 balances in the accompanying unaudited condensed consolidated balance sheets.

The transaction price is stated at the purchase order level, which includes shipping and/or freight costs and any applicable governmental authority taxes. The majority of our contracts have a single performance obligation concentrated around the delivery of goods to the carrier, Free On Board (FOB) shipping point. Therefore, revenue is recognized when this performance obligation is satisfied. Generally, title and control passes at the time of shipment.

The allocation of these costs are applied at the invoice level and recognized in conjunction with revenue. Additionally, returns and refunds are estimated on a historical and expected basis which is a reduction of revenue recognized.

In addition, on June 26, 2021, we were parties either as plaintiff or defendant to a number of lawsuits and claims arising through the normal course of our business. In the opinion of management, our consolidated financial statements will not be materially affected by the outcome of these contingencies and claims. On June 26, 2021, we had outstanding purchase commitments on commenced capital projects of approximately $45.1 million. We provide a variety of warranties for products we manufacture. Historically, warranty claims have not been material. We also distribute products manufactured by other companies, some of which are no longer in business. While we do not warrant these products, we have received claims as a distributor of these products when the manufacturer no longer exists or has the ability to pay. Historically, these costs have not had a material effect on our consolidated financial statements. As part of our operations, we supply building materials and labor to site-built construction projects or we jointly bid on contracts with framing companies for such projects. In some instances, we are required to post payment and performance bonds to ensure the products and installation services are completed in accordance with our contractual obligations. We have agreed to indemnify the surety for claims properly made against these bonds. As of June 26, 2021, we had approximately $36.4 million outstanding payment and performance bonds for open projects. We had approximately $2.1 million in payment and performance bonds outstanding for completed projects which are still under warranty. On June 26, 2021, we had outstanding letters of credit totaling $52.7 million, primarily related to certain insurance contracts and industrial development revenue bonds described further below. In lieu of cash deposits, we provide irrevocable letters of credit in favor of our insurers to guarantee our performance under certain insurance contracts. As of June 26, 2021, we have irrevocable letters of credit outstanding totaling approximately $45.6 million for these types of insurance arrangements. We have reserves recorded on our balance sheet, in accrued liabilities, that reflect our expected future liabilities under these insurance arrangements. We are required to provide irrevocable letters of credit in favor of the bond trustees for all industrial development revenue bonds that have been issued. These letters of credit guarantee principal and interest payments to the bondholders. We currently have irrevocable letters of credit outstanding totaling approximately $7.1 million related to our outstanding industrial development revenue bonds. These letters of credit have varying terms but may be renewed at the option of the issuing banks. Certain wholly owned domestic subsidiaries have guaranteed the indebtedness of UFP Industries, Inc. in certain debt agreements, including the Series 2012, 2018 and 2020 Senior Notes and our revolving credit facility. The maximum exposure of these guarantees is limited to the indebtedness outstanding under these debt arrangements and this exposure will expire concurrent with the expiration of the debt agreements. We did not enter into any new guarantee arrangements during the second quarter of 2021 which would require us to recognize a liability on our balance sheet.
