Debt Obligations | 6.Debt Obligations Bank Borrowings. During 2018, we amended and restated our unsecured credit agreement to replace the previous unsecured credit agreement, prior to its expiration on October 14, 2018. The amended credit agreement maintains the $600,000,000 aggregate commitment of the lenders under the prior agreement and provides for the opportunity to increase the commitment size of the credit agreement up to a total of $1,000,000,000. The amended credit agreement extends the maturity of the credit agreement to June 27, 2022 and provides for a one-year extension option at our discretion, subject to customary conditions. Additionally, the amended credit agreement decreases the interest rate margins and converts from the payment of unused commitment fees to a facility fee. Based on our leverage at September 30, 2018, the facility provides for interest annually at LIBOR plus 115 basis points and a facility fee of 20 basis points. At September 30, 2018, we were in compliance with all covenants. Senior Unsecured Notes.
