Debt and Receivables Securitization	9 Months Ended
Feb. 28, 2018
Debt and Receivables Securitization	NOTE G – Debt and Receivables Securitization On July 28, 2017, we issued $200,000,000 aggregate principal amount of senior unsecured notes due August 1, 2032 (the “2032 Notes”). The 2032 Notes bear interest at a rate of 4.300%. The 2032 Notes were sold to the public at 99.901% of the principal amount thereof, to yield 4.309% to maturity. We used a portion of the net proceeds from the offering to repay amounts then outstanding under our multi-year revolving credit facility and amounts then outstanding under our revolving trade accounts receivable securitization facility, both of which are described in more detail below. We entered into an interest rate swap in June 2017, in anticipation of the issuance of the 2032 Notes. The interest rate swap had a notional amount of $150,000,000 to hedge the risk of changes in the semi-annual interest rate payments attributable to changes in the benchmark interest rate during the several days leading up to the issuance of the 2032 Notes. Upon pricing of the 2032 Notes, the derivative instrument was settled resulting in a gain of approximately $3,098,000, which was reflected in accumulated other comprehensive income (“AOCI”). Approximately $2,116,000 and $198,000 were allocated to debt issuance costs and the debt discount. The debt issuance costs and the debt discount were each recorded on the consolidated balance sheet within long-term debt as a contra-liability. The unamortized portion of the debt issuance costs and debt discount was $2,034,000 and $190,000, respectively, at February 28, 2018. We maintain a $500,000,000 multi-year revolving credit facility (the “Credit Facility”) with a group of lenders. On February 16, 2018, the Company amended the terms of the Credit Facility, extending the maturity by three years to February 2023. Debt issuance costs of $805,000 were incurred as a result of the renewal. These costs have been deferred and will be amortized over the life of the Credit Facility to interest expense. Borrowings under the Credit Facility typically have maturities of less than one year. However, we can extend the term of amounts borrowed by renewing these borrowings for the term of the Credit Facility. 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, 2018. As discussed in “NOTE F – Guarantees,” we provided $14,606,000 in stand-by letters of credit for third-party beneficiaries as of February 28, 2018. While not drawn against at February 28, 2018, $13,245,000 of these stand-by letters of credit were issued against availability under the Credit Facility, leaving $486,755,000 available under the Credit Facility at February 28, 2018. We also maintain a $50,000,000 revolving trade accounts receivable securitization facility (the “AR Facility”) which matures in January 2019. On January 16, 2018, the Company amended the terms of the AR Facility, extending the maturity by one year to January 2019 and reducing the borrowing capacity from $100,000,000 to $50,000,000. 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 $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, 2018, no undivided ownership interests in this pool of accounts receivable had been sold.

NOTE G – Debt and Receivables Securitization

On July 28, 2017, we issued $200,000,000 aggregate principal amount of senior unsecured notes due August 1, 2032 (the “2032 Notes”). The 2032 Notes bear interest at a rate of 4.300%. The 2032 Notes were sold to the public at 99.901% of the principal amount thereof, to yield 4.309% to maturity. We used a portion of the net proceeds from the offering to repay amounts then outstanding under our multi-year revolving credit facility and amounts then outstanding under our revolving trade accounts receivable securitization facility, both of which are described in more detail below. We entered into an interest rate swap in June 2017, in anticipation of the issuance of the 2032 Notes. The interest rate swap had a notional amount of $150,000,000 to hedge the risk of changes in the semi-annual interest rate payments attributable to changes in the benchmark interest rate during the several days leading up to the issuance of the 2032 Notes.

The unamortized portion of the debt issuance costs and debt discount was $2,034,000 and $190,000, respectively, at February 28, 2018.

We maintain a $500,000,000 multi-year revolving credit facility (the “Credit Facility”) with a group of lenders. On February 16, 2018, the Company amended the terms of the Credit Facility, extending the maturity by three years to February 2023. Debt issuance costs of $805,000 were incurred as a result of the renewal. These costs have been deferred and will be amortized over the life of the Credit Facility to interest expense. Borrowings under the Credit Facility typically have maturities of less than one year. However, we can extend the term of amounts borrowed by renewing these borrowings for the term of the Credit Facility. 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, 2018. As discussed in “NOTE F – Guarantees,” we provided $14,606,000 in stand-by letters of credit for third-party beneficiaries as of February 28, 2018. While not drawn against at February 28, 2018, $13,245,000 of these stand-by letters of credit were issued against availability under the Credit Facility, leaving $486,755,000 available under the Credit Facility at February 28, 2018.

We also maintain a $50,000,000 revolving trade accounts receivable securitization facility (the “AR Facility”) which matures in January 2019. On January 16, 2018, the Company amended the terms of the AR Facility, extending the maturity by one year to January 2019 and reducing the borrowing capacity from $100,000,000 to $50,000,000. 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 $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, 2018, no undivided ownership interests in this pool of accounts receivable had been sold.
