Deferred financing costs relate to our asset-backed securitizations and our term loan facility. Amortization of deferred financing costs was $1.4 million and $2.2 million for the three months ended September 30, 2017 and 2016, respectively, and $5.0 million and $6.3 million for the nine months ended September 30, 2017 and 2016, respectively, which has been included in gross interest, prior to interest capitalization.

Early Extinguishment of Debt

During the second quarter of 2017, the Company paid off the outstanding principal on the AH4R 2014-SFR1 asset-backed securitization of approximately $455.4 million using proceeds from the Class A common share offering in the first quarter of 2017 and available cash, which resulted in $6.6 million of charges primarily related to the write-off of unamortized deferred financing costs that were included in loss on early extinguishment of debt within the condensed consolidated statements of operations. The payoff of the AH4R 2014-SFR1 asset-backed securitization also resulted in the release of the 3,799 homes pledged as collateral and $9.4 million of restricted cash for lender requirements.

Exchangeable Senior Notes, Net

The exchangeable senior notes, which were assumed in connection with the Company's merger (the "ARPI Merger") with American Residential Properties, Inc. ("ARPI") during 2016, are senior unsecured obligations of the Operating Partnership and rank equally in right of payment with all other existing and future senior unsecured indebtedness of the Operating Partnership. The Operating Partnership’s obligations under the exchangeable senior notes are fully and unconditionally guaranteed by the Company. The exchangeable senior notes bear interest at a rate of 3.25% per annum and contain an exchange settlement feature, which provides that the exchangeable senior notes may, under certain circumstances, be exchangeable for cash, our Class A common shares or a combination of cash and our Class A common shares, at the option of the Operating Partnership, based on an initial exchange rate of 46.9423 shares of ARPI's common stock per $1,000 principal amount of the notes. Settlements for cash will be paid for by the Operating Partnership, while settlements for the Company's Class A common shares will be issued by AH4R with the Operating Partnership issuing an equivalent number of Class A units to AH4R. The adjusted initial exchange rate would be 53.2795 of our Class A common shares per $1,000 principal amount of the notes, based on the 1.135 exchange ratio of ARPI shares to our shares resulting from the ARPI Merger. The current exchange rate as of September 30, 2017, was 55.1453 of our Class A common shares per $1,000 principal amount of the notes. The exchange rate is adjusted based on our Class A common share price and distributions to common shareholders.

As of September 30, 2017, the exchangeable senior notes, net had a balance of $110.8 million in the condensed consolidated balance sheets, which was net of an unamortized discount of $1.2 million and $3.1 million of unamortized fair value of the exchange settlement feature, which was included in additional paid-in capital within the Company's condensed consolidated balance sheets and was included in general partner's common capital within the Operating Partnership's condensed consolidated balance sheets.

Credit Facilities

During 2016, the Company entered into a $1.0 billion credit agreement, which was subsequently amended in June 2017. The amendment expanded our borrowing capacity on the revolving credit facility to $800.0 million and reduced the term loan facility to $200.0 million. The amendment also lowered our cost of borrowing and provides a more flexible borrowing structure. The interest rate on the revolving credit facility is, at the Company’s election, a LIBOR rate plus a margin ranging from 0.825% to 1.55% or a base rate (generally determined according to a prime rate or federal funds rate) plus a margin ranging from 0.00% to 0.55%. Borrowings under the term loan facility accrue interest, at the Company’s election, at either a LIBOR rate plus a margin ranging from 0.90% to 1.75% or a base rate plus a margin ranging from 0.00% to 0.75%. In each case, the actual margin is determined based on the Company's credit ratings in effect from time to time. Based on current corporate ratings for LIBOR-based borrowings as of September 30, 2017, the revolving credit facility bears interest at 1-month LIBOR plus 1.20%, and the term loan facility bears interest at 1-month LIBOR plus 1.35%. The credit agreement includes an accordion feature allowing the revolving credit facility or the term loan facility to be increased to an aggregate amount not to exceed $1.75 billion, subject to certain conditions. The revolving credit facility matures on June 30, 2021, with two six-month extension options at the Company's election upon payment of an extension fee, and the term loan facility matures on June 30, 2022. No amortization payments are required on the term loan facility prior to the maturity date. The credit agreement requires that we maintain certain financial covenants. As of September 30, 2017 and December 31, 2016, the Company had no outstanding borrowings against the revolving credit facility, $200.0 million and $325.0 million, respectively, of outstanding borrowings against the term loan facility and was in compliance with all loan covenants.
