Revolving Credit Facility

As of June 30, 2017, our Credit Facility had $1.395 billion of total commitments and $850 million of outstanding borrowings. As of June 30, 2017, we had approximately $518 million available for borrowings without violating financial covenants. Approximately $275 million of the commitments under the Credit Facility mature in May 2018 with the remaining $1.12 billion of the commitments maturing in May 2019. We were in compliance with all financial covenants under the Credit Facility as of June 30, 2017 and September 30, 2016, and we anticipate that we will continue to be in compliance for at least twelve months subsequent to the date our financial statements are issued.

The weighted-average effective interest rate on our long-term debt was approximately 5.1% per annum as of June 30, 2017. The effective rate was determined after giving consideration to the effect of our interest rate swaps accounted for as hedges and the amortization of our debt issuance costs and debt premiums. Interest capitalized for the three and nine months ended June 30, 2017 was approximately $6.8 million and $18.8 million, respectively. Interest capitalized for the three and nine months ended June 30, 2016 was approximately $4.2 million and $12.8 million, respectively.
