Debt Disclosure [Abstract]
Debt and Receivables Securitization	NOTE H – Debt and Receivables Securitization 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 28, 2019. As discussed in “NOTE G – Guarantees,” we provided $15,366,000 in letters of credit for third-party beneficiaries as of February 28, 2019. While not drawn against at February 28, 2019, $1,950,000 of these letters of credit were issued against availability under the Credit Facility, leaving $498,050,000 available at February 28, 2019. We also maintain a $50,000,000 revolving trade accounts receivable securitization facility (the “AR Facility”). On January 15, 2019, the Company extended the maturity of the AR Facility by one year to January 2020. 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 $50,000,000 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 28, 2019, no undivided ownership interests in this pool of accounts receivable had been sold.
