5.Debt Obligations

Bank Borrowings. We have an Unsecured Credit Agreement that provides for a revolving line of credit up to $600,000,000. The Unsecured Credit Agreement matures on October 14, 2018 and provides for a one-year extension option at our discretion, subject to customary conditions. Based on our leverage at September 30, 2017, the facility provides for interest annually at LIBOR plus 150 basis points and an unused commitment fee of 35 basis points. At September 30, 2017, we were in compliance with all covenants.

Senior Unsecured Notes. During the nine months ended September 30, 2017, we amended our shelf agreement with affiliates and managed accounts of Prudential Investment Management, Inc. (or Prudential) to increase our shelf commitment to $337,500,000.
