During the six-month period ended June 30, 2026, using proceeds from the sale of our Refining Solutions business and cash on hand, we redeemed the 4.65% Senior notes in full, and repurchased $62.4 million of the 3.45% Senior notes, $184.3 million of the 5.05% Senior notes, $149.0 million of the 5.45% Senior notes, and $254.3 million of the 5.65% Senior notes. As a result, included in Interest and financing expenses for the six-month period ended June 30, 2026 is a gain on early extinguishment of debt of $12.5 million, representing the repurchase of these notes at a discount, partially offset by tender premiums and redemption fees.

We are party to master receivables purchase agreements, under which we may sell available and eligible outstanding customer accounts receivable generated by sales to certain customers of up to approximately $249 million at any one time. The agreements are uncommitted and can be terminated by us or the purchaser upon notice in accordance with the terms of the agreements. Transactions under these agreements are accounted for as sales of accounts receivable, and the receivables sold are removed from the consolidated balance sheets as of the effective time of the sales transaction. During the three-month and six-month periods ended June 30, 2026, the Company sold and removed approximately $281.6 million and $516.7 million, respectively, of accounts receivable under the master receivables purchase agreements. The Company incurred approximately $1.9 million and $3.5 million, respectively, of fees associated with the master receivables purchase agreements during the three-month and six-month periods ended June 30, 2026. Costs associated with the sales of receivables are reflected in the consolidated statements of income for the periods in which the sales occur.
