Debt Disclosure [Abstract]
Debt and Receivables Securitization	NOTE I – Debt and Receivables Securitization On August 23, 2019, two of our European subsidiaries issued a €36,700,000 principal amount unsecured 1.56% Series A Senior Note due August 23, 2031 (the “2031 Note”) and €55,000,000 aggregate principal amount of unsecured 1.90% Series B Senior Notes due August 23, 2034 (the “2034 Notes”), (collectively, the “Senior Notes”). The 2031 Note is to be repaid in the principal amount of €30,000,000, together with accrued interest, on August 23, 2029, with the remaining €6,700,000 principal amount payable on August 23, 2031, together with accrued interest. The 2034 Notes are to be repaid in the aggregate principal amount of €23,300,000, together with accrued interest, on August 23, 2031, with the remaining €31,700,000 aggregate principal amount payable on August 23, 2034, together with accrued interest. Debt issuance costs of $134,000 were incurred in connection with the issuance of the Senior Notes and have been recorded on the consolidated balance sheet within long-term debt as a contra-liability. They will continue to be amortized, through interest expense, in our consolidated statements of earnings over the term of the respective Senior Notes. The unamortized portion of the debt issuance costs was $128,000 at February 29, 2020. The Senior Notes were issued in a private placement and the proceeds thereof were used to redeem $150,000,000 aggregate principal amount of unsecured 6.50% senior notes that were set to mature on April 15, 2020 (the “2020 Notes”). The 2020 Notes were redeemed in full on August 30, 2019. In connection with the early redemption, the Company recognized a loss on extinguishment of debt of $4,034,000, which has been presented separately in our consolidated statements of earnings. We maintain a $500,000,000 multi-year revolving credit facility (the “Credit Facility”) with a group of lenders which matures in February 2023. Borrowings under the Credit Facility have maturities of up to one year. We have the option to borrow at rates equal to an applicable margin over the LIBOR, Prime Rate or Overnight Bank Funding Rate. The applicable margin is determined by our credit rating. There were no borrowings outstanding under the Credit Facility at February 29, 2020. As discussed in “NOTE H – Guarantees,” we provided $15,300,000 in stand-by letters of credit for third-party beneficiaries as of February 29, 2020. While not drawn against at February 29, 2020, $450,000 of these letters of credit were issued against availability under the Credit Facility, leaving $499,550,000 available at February 29, 2020. We also maintain a revolving trade accounts receivable securitization facility (the “AR Facility”). On January 13, 2020, the Company extended the maturity of the AR Facility by one year to January 2021 and reduced the borrowing capacity from $50,000,000 to $10,000,000. Pursuant to the terms of the AR Facility, certain of our subsidiaries sell their accounts receivable without recourse, on a revolving basis, to Worthington Receivables Corporation (“WRC”), a wholly-owned, consolidated, bankruptcy-remote subsidiary. In turn, WRC may sell without recourse, on a revolving basis, up to $10,000,000 of undivided ownership interests in this pool of accounts receivable to a third-party bank. We retain an undivided interest in this pool and are subject to risk of loss based on the collectability of the receivables from this retained interest. Because the amount eligible to be sold excludes receivables more than 90 days past due, receivables offset by an allowance for doubtful accounts due to bankruptcy or other cause, concentrations over certain limits with specific customers and certain reserve amounts, we believe additional risk of loss is minimal. As of February 29, 2020, no undivided ownership interests in this pool of accounts receivable had been sold.

They will continue to be amortized, through interest expense, in our consolidated statements of earnings over the term of the respective Senior Notes. The unamortized portion of the debt issuance costs was $128,000 at February 29, 2020.

The Senior Notes were issued in a private placement and the proceeds thereof were used to redeem $150,000,000 aggregate principal amount of unsecured 6.50% senior notes that were set to mature on April 15, 2020 (the “2020 Notes”). The 2020 Notes were redeemed in full on August 30, 2019. In connection with the early redemption, the Company recognized a loss on extinguishment of debt of $4,034,000, which has been presented separately in our consolidated statements of earnings.

We maintain a $500,000,000 multi-year revolving credit facility (the “Credit Facility”) with a group of lenders which matures in February 2023. Borrowings under the Credit Facility have maturities of up to one year. We have the option to borrow at rates equal to an applicable margin over the LIBOR, Prime Rate or Overnight Bank Funding Rate. The applicable margin is determined by our credit rating. There were no borrowings outstanding under the Credit Facility at February 29, 2020. As discussed in “NOTE H – Guarantees,” we provided $15,300,000 in stand-by letters of credit for third-party beneficiaries as of February 29, 2020. While not drawn against at February 29, 2020, $450,000 of these letters of credit were issued against availability under the Credit Facility, leaving $499,550,000 available at February 29, 2020.

We also maintain a revolving trade accounts receivable securitization facility (the “AR Facility”). On January 13, 2020, the Company extended the maturity of the AR Facility by one year to January 2021 and reduced the borrowing capacity from $50,000,000 to $10,000,000. Pursuant to the terms of the AR Facility, certain of our subsidiaries sell their accounts receivable without recourse, on a revolving basis, to Worthington Receivables Corporation (“WRC”), a wholly-owned, consolidated, bankruptcy-remote subsidiary. In turn, WRC may sell without recourse, on a revolving basis, up to $10,000,000 of undivided ownership interests in this pool of accounts receivable to a third-party bank. We retain an undivided interest in this pool and are subject to risk of loss based on the collectability of the receivables from this retained interest. Because the amount eligible to be sold excludes receivables more than 90 days past due, receivables offset by an allowance for doubtful accounts due to bankruptcy or other cause, concentrations over certain limits with specific customers and certain reserve amounts, we believe additional risk of loss is minimal. As of February 29, 2020, no undivided ownership interests in this pool of accounts receivable had been sold.
