Asset-backed Securitizations May 2014 Securitization In May 2014, we completed a private securitization transaction (the "2014-SFR1 securitization") in which a newly-formed special purpose entity (the "2014-SFR1 Borrower") entered into a loan with a third-party lender (the "2014-SFR1 Lender") for $481.0 million represented by a promissory note. In addition, the Company entered into an interest rate cap agreement for the initial two year term of the loan, with a LIBOR based strike rate equal to 3.85%. The 2014-SFR1 Borrower under the loan is wholly owned by another special purpose entity (the "2014-SFR1 Equity Owner") and the 2014-SFR1 Equity Owner is wholly owned by our operating partnership. The loan is a two-year, floating rate loan, comprised of six floating rate components computed monthly based on 1-month LIBOR for each interest period plus a fixed component spread for each of the six components resulting in a duration-weighted blended interest rate of LIBOR plus 1.54%, subject to a LIBOR floor of 0.25%. The note requires monthly payments of interest together with principal payments representing one-twelfth of one percent of the original principal amount. The loan may be extended for three, 12-month extensions at the 2014-SFR1 Borrower's option, resulting in a fully extended maturity date of June 9, 2019, provided that there is no event of default under the loan agreement, the Borrower obtains a replacement interest rate cap agreement in a form reasonably acceptable to the 2014-SFR1 Lender and the 2014-SFR1 Borrower complies with the other terms set forth in the loan agreement. The note was immediately transferred by the 2014-SFR1 Lender to a subsidiary of the Company and then to a REMIC trust in exchange for seven classes of single-family rental pass-through certificates representing all of the beneficial ownership interests in the loan and the trust. Upon receipt of the certificates, a subsidiary of the Company sold the certificates to investors for gross proceeds of $481.0 million, before issuance costs of $14.9 million. Proceeds from this transaction were used to pay down the outstanding balance on the credit facility. The principal amount of each class of certificates corresponds to the corresponding principal amount of the loan components with an additional class to hold the residual REMIC interest. The loan was originally secured by first priority mortgages on a pool of 3,852 single-family residential properties transferred to the 2014-SFR1 Borrower from the Company's portfolio of properties. During the year ended December 31, 2016, the Company sold 47 single-family homes from the pool of single-family homes and had two that were disqualified for a total release price of $14.5 million, which was used to pay down the principal balance on the note and also reduced the pool of 3,852 single-family homes set as collateral to 3,803 single-family homes. The 2014-SFR1 Borrower's homes were substantially similar to the other properties owned by the Company and were leased to tenants underwritten on substantially the same basis as the tenants in the Company's other properties. During the duration of the loan, the 2014-SFR1 Borrower's properties may not generally be transferred, sold or otherwise securitized, the Company can substitute properties only if a property owned by the 2014-SFR1 Borrower becomes a disqualified property under the terms of the loan, and the 2014-SFR1 Borrower is limited in its ability to incur any additional indebtedness. The loan is also secured by a security interest in all of the 2014-SFR1 Borrower's personal property and a pledge of all of the assets of the 2014-SFR1 Equity Owner, including a security interest in its membership interest in the 2014-SFR1 Borrower. The Company provides a limited guaranty (i) for certain losses arising out of designated acts of intentional misconduct and (ii) for the principal amount of the loan and all other obligations under the loan agreement in the event of insolvency or bankruptcy proceedings. The loan agreement provides that the 2014-SFR1 Borrower maintain covenants typical for securitization transactions including establishing and maintaining a cash management account controlled by the 2014-SFR1 Lender to collect all rents and cash generated by the 2014-SFR1 Borrower's properties. In the absence of an event of default, the 2014-SFR1 Borrower will receive any excess cash after payment of monthly interest, principal and property related expenses. Upon the occurrence of an event of default under the loan or if the 2014-SFR1 Borrower does not maintain a debt yield (net cash flow divided by the outstanding principal balance of the loan) on the portfolio of at least 6.68%, the 2014-SFR1 Lender may transfer the excess cash to an account and apply any funds in such account as the 2014-SFR1 Lender elects, including to prepay principal and pay any amounts due under the loan. The 2014-SFR1 Lender may also foreclose on its security interests, in limited circumstances may enforce the Company's guaranty and may appoint a new property manager. As of December 31, 2016, the Company was in compliance with all covenants under the loan agreement. The Company has accounted for the transfer of the note from its subsidiary to the trust as a sale under ASC 860, Transfers and Servicing, with no resulting gain or loss as the note was both originated by the third-party lender and immediately transferred at the same fair market value. The Company has also evaluated and not identified any variable interests in the trust. Accordingly, the Company continues to consolidate, at historical cost basis, the 3,803 homes placed as collateral for the note. The principal balance outstanding on the note was $456.1 million and $473.8 million as of December 31, 2016 and 2015, respectively, and was included in asset-backed securitizations, net within the consolidated balance sheets. The 3,803 homes and 3,852 homes set as collateral had a net book value of $575.4 million and $606.9 million as of December 31, 2016 and 2015, respectively. The interest rate cap agreement entered into as part of the securitization transaction has been formally designated as a cash flow hedge at inception and will be regularly assessed for effectiveness on an ongoing basis. During the year ended December 31, 2016, the Company's interest rate cap agreement was 100% effective as a cash flow hedge and, as a result, changes in fair value have been classified in accumulated other comprehensive income or loss. These amounts will subsequently be reclassified into earnings in the period in which the hedged transaction affects earnings. The fair value of the interest rate cap agreement is estimated to be zero as of December 31, 2016, (see Note 15) and has been included in escrow deposits, prepaid expenses and other assets in the consolidated balance sheets. September 2014 Securitization In September 2014, we completed our second securitization transaction (the "2014-SFR2 securitization"), which was structured substantially similar to the 2014-SFR1 securitization. The principal differences from the 2014-SFR1 securitization are: (1) the loan is a fixed rate loan for $513.3 million with a 10 year term, maturity date of October 9, 2024, and a duration-adjusted weighted-average interest rate of 4.42%, (2) no interest rate cap agreement was part of the transaction, (3) the loan was originally secured by first priority mortgages on a portfolio of 4,487 single-family residential properties owned by the borrower, a subsidiary of the Company and (4) in lieu of a debt yield requirement, the loan agreement provides that if the borrower does not maintain a debt service coverage ratio of at least 1.20 to 1.00, the lender may transfer cash to an account from which the lender may apply funds as it elects, including prepayment of the loan and principal. During the year ended December 31, 2016, the Company had three single-family homes that were disqualified for a total release price of $0.4 million, which was used to pay down the principal balance on the note and also reduced the pool of 4,487 single-family homes set as collateral to 4,484 single-family homes. The loan agreement defines the debt service coverage ratio as of any determination date as a ratio in which the numerator is the net cash flow (as defined in the loan agreement) divided by the aggregate debt service for the 12 month period following the date of determination. Also, in addition to the single-family rental pass-through certificates sold to third parties, the Company acquired all of the Class F certificates, which bear no interest, for $25.7 million. Gross proceeds to the Company from the 2014-SFR2 securitization, after purchase of the Class F certificates, were $487.7 million, before issuance costs of $12.9 million. Proceeds from this transaction were used to pay down the outstanding balance on the credit facility and for general corporate purposes. The Company has accounted for the transfer of the 2014-SFR2 securitization promissory note to the trust as a sale under ASC 860, Transfers and Servicing, with no resulting gain or loss as the note was both originated by the third-party lender and immediately transferred at the same fair market value. The Company has also evaluated the purchased Class F certificates as a variable interest in the trust and has concluded that the Class F certificates will not absorb a majority of the trust's expected losses or receive a majority of the trust's expected residual returns. Additionally, the Company has concluded that the Class F certificates do not provide the Company with any ability to direct activities that could impact the trust's economic performance. The Company does not consolidate the trust and continues to consolidate, at historical cost basis, the 4,484 homes placed as collateral for the note. The principal balance outstanding on the note was $501.8 million and $507.3 million as of December 31, 2016 and 2015, respectively, and was included in asset-backed securitizations, net within the consolidated balance sheets. Separately, the $25.7 million of purchased Class F certificates have been reflected as asset-backed securitization certificates in the consolidated balance sheets. The 4,484 homes and 4,487 homes set as collateral had a net book value of $650.2 million and $672.3 million as of December 31, 2016 and 2015, respectively. November 2014 Securitization In November 2014, we completed our third securitization transaction (the "2014-SFR3 securitization"), which was structured substantially similar to the 2014-SFR2 securitization. The principal differences from the 2014-SFR2 securitization are: (1) the loan is a fixed rate loan for $528.4 million with a 10 year term, maturity date of December 9, 2024, and a duration-adjusted weighted-average interest rate of 4.40%, (2) the loan is secured by first priority mortgages on a portfolio of 4,503 single-family residential properties owned by the borrower, a subsidiary of the Company and (3) the Company did not acquire any of the certificates associated with this transaction. Gross proceeds to the Company from the 2014-SFR3 securitization were $528.4 million, before issuance costs of $12.9 million. Proceeds from this transaction were used to pay down the outstanding balance on the credit facility and for general corporate purposes. The Company consolidates, at historical cost basis, the 4,503 homes placed as collateral for the note. The principal balance outstanding on the note was $517.8 million and $523.1 million as of December 31, 2016 and 2015, respectively, and was included in asset-backed securitizations, net within the consolidated balance sheets. The 4,503 homes set as collateral had a net book value of $706.3 million and $729.8 million as of December 31, 2016 and 2015, respectively. March 2015 Securitization In March 2015, we completed our fourth securitization transaction (the “2015-SFR1 securitization”), which was structured substantially similar to the 2014-SFR3 securitization. The principal differences from the 2014-SFR3 securitization are: (1) the loan is a fixed-rate loan for $552.8 million with a 30 year term, maturity date of April 9, 2045, and a duration-adjusted weighted-average interest rate of 4.14%, (2) the loan was originally secured by first priority mortgages on a pool of 4,661 single-family residential properties owned by the Borrower, a subsidiary of the Company and (3) the loan has an anticipated repayment date of April 9, 2025. During the year ended December 31, 2016, the Company had one single-family home that was disqualified for a total release price of $0.1 million, which was used to pay down the principal balance on the note and also reduced the pool of 4,661 single-family homes set as collateral to 4,660 single-family homes. The note was immediately transferred by the third-party lender to a subsidiary of the Company and then to a REMIC trust in exchange for eight classes of single-family rental pass-through certificates representing all of the beneficial ownership interests in the loan and the trust. Upon receipt of the certificates, a subsidiary of the Company sold the certificates to investors for gross proceeds of $552.8 million, before issuance costs of $13.3 million. Proceeds from this transaction were used to pay down the outstanding balance on the credit facility and for general corporate purposes. The Company consolidates, at historical cost basis, the 4,660 homes placed as collateral for the note. The principal balance outstanding on the note was $543.5 million and $549.1 million as of December 31, 2016 and 2015, respectively, and was included in asset-backed securitizations, net within the consolidated balance sheets. The 4,660 homes and 4,661 homes set as collateral had a net book value of $710.8 million and $735.0 million as of December 31, 2016 and 2015, respectively. September 2015 Securitization In September 2015, we completed our fifth securitization transaction (the “2015-SFR2 securitization”), which was structured substantially similar to the 2015-SFR1 securitization. The principal differences from the 2015-SFR1 securitization are: (1) the loan is a fixed-rate loan for $477.7 million with a 30 year term, maturity date of October 9, 2045, and a duration-adjusted weighted-average interest rate of 4.36%, (2) the loan was originally secured by first priority mortgages on a portfolio of 4,125 single-family residential properties owned by the borrower, a subsidiary of the Company and (3) the loan has an anticipated repayment date of October 9, 2025. During the year ended December 31, 2016, the Company had one single-family home that was disqualified for a total release price of $0.1 million, which was used to pay down the principal balance on the note and also reduced the pool of 4,125 single-family homes set as collateral to 4,124 single-family homes. The note was immediately transferred by the third-party lender to a subsidiary of the Company and then to a REMIC trust in exchange for seven classes of single-family rental pass-through certificates representing all the beneficial ownership interests in the loan and the trust. Upon receipt of the certificates, a subsidiary of the Company sold the certificates to investors for gross proceeds of $477.7 million, before issuance costs of $11.3 million. Proceeds from this transaction were used to pay down the outstanding balance on the credit facility and for general corporate purposes. The Company consolidates, at historical cost basis, the 4,124 homes placed as collateral for the note. The principal balance outstanding on the note was $472.0 million and $476.9 million as of December 31, 2016 and 2015, respectively, and was included in asset-backed securitizations, net within the consolidated balance sheets. The 4,124 homes and 4,125 homes set as collateral had a net book value of $658.8 million and $681.4 million as of December 31, 2016 and 2015, respectively. ARP 2014-SFR1 Securitization In connection with the ARPI Merger on February 29, 2016 (see Note 11), the Company assumed a securitization loan (the "ARP 2014-SFR1 securitization”), which involved the issuance and sale of single-family rental pass-through certificates that represent beneficial ownership interests in a loan secured by 2,875 homes held by a special purpose entity, ARP 2014-SFR1 Borrower, LLC (the “ARP 2014-SFR1 Borrower”). The ARP 2014-SFR1 Borrower under the loan was wholly owned by another special purpose entity (the “ARP 2014-SFR1 Equity Owner”) and the ARP 2014-SFR1 Equity Owner was wholly owned by the operating partnership. The loan, at the time of its origination by ARPI in August 2014, had an original principal amount of $342.2 million and an initial term of two years, with three, 12-month extension options, resulting in a fully extended maturity date of September 9, 2019. It was comprised of six floating rate components computed monthly based on 1-month LIBOR for each interest period plus a fixed component spread for each of the six components resulting in an effective weighted-average interest rate of 1-month LIBOR plus 2.11%. Interest on the loan was paid monthly. The 2,875 homes securing the loan were substantially similar to the other properties owned by the Company and were leased to tenants underwritten on substantially the same basis as the tenants in the Company’s other properties. During the duration of the loan, the ARP 2014-SFR1 Borrower’s properties were not generally able to be transferred, sold or otherwise securitized, the Company could have substituted properties only if a property owned by the ARP 2014-SFR1 Borrower became a disqualified property under the terms of the loan, and the ARP 2014-SFR1 Borrower was limited in its ability to incur any additional indebtedness. The loan was also secured by a security interest in all of the ARP 2014-SFR1 Borrower’s personal property and a pledge of all of the assets of the ARP 2014-SFR1 Equity Owner, including a security interest in its membership interest in the ARP 2014-SFR1 Borrower. The Company provided a limited guaranty (i) for certain losses arising out of designated acts of intentional misconduct and (ii) for the principal amount of the loan and all other obligations under the loan agreement in the event of insolvency or bankruptcy proceedings. The loan required that we maintained certain covenants, including but not limited to, a minimum debt yield on the collateral pool of properties. In September 2016, the Company paid off the ARP 2014-SFR1 asset-backed securitization using available cash and borrowings from our credit facilities, which resulted in a $10.7 million loss on early extinguishment of debt related to the write-off of the discount on the securitization. The payoff of the ARP 2014-SFR1 asset-backed securitization resulted in the release of the 2,875 collateralized homes and $10.1 million of restricted cash for lender requirements. Exchangeable Senior Notes, Net In connection with the ARPI Merger on February 29, 2016 (see Note 11), the Company assumed 3.25% exchangeable senior notes due 2018 that have a $115.0 million aggregate principal amount and a fair value at assumption of $112.3 million. The exchangeable senior notes 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. Interest is payable in arrears on May 15 and November 15 of each year, beginning May 15, 2016, until the maturity date of November 15, 2018. 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, shares of our common stock or a combination of cash and shares of our common stock, 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. The adjusted initial exchange rate would be 53.2795 shares of our common stock 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 December 31, 2016, was 54.7701 shares of our common stock per $1,000 principal amount of the notes. The exchange rate changes over time based on our common share price and distributions to common shareholders. Prior to the close of business on the business day immediately preceding August 15, 2018, the notes will be exchangeable at the option of the holders only under the following circumstances: (1) during any calendar quarter beginning after December 31, 2013 (and only during such quarter) if the closing sale price per share of our common stock is more than 130% of the then-current exchange price for at least 20 trading days (whether or not consecutive) in the period of 30 consecutive trading days ending on the last trading day of the preceding calendar quarter; (2) during the 5 consecutive business-day period following any 5 consecutive trading-day period in which the trading price per $1,000 principal amount of notes was less than 98% of the product of the closing sale price per share of our common stock multiplied by the then-current exchange rate; or (3) upon the occurrence of specified corporate transactions described in the indenture. On or after August 15, 2018, the notes will be exchangeable at any time prior to the close of business on the second business day immediately preceding the maturity date. Subject to its election to satisfy its exchange obligations entirely in shares of our common stock, upon exchange, the operating partnership will pay or deliver, as the case may be, to exchanging holders in respect of each $1,000 principal amount of notes being exchanged a settlement amount either solely in cash, solely in common shares or in a combination of cash and shares of our common stock. The fair value of the exchangeable senior notes, which was calculated using a binomial lattice model at the time of assumption, was $112.3 million, which represents the $115.0 million face value less a discount of $2.7 million, which will be amortized using the effective interest method over the term of the notes. The amount recorded to exchangeable senior notes, net at the time of assumption was $105.3 million, which represents the fair value of $112.3 million, less the fair value of the exchange settlement feature of the notes of $7.0 million, which was calculated using a straight-debt rate of 6.7% at the time of assumption. The fair value of the exchange settlement feature was recorded in additional paid-in capital and will be amortized using the effective interest method over the term of the notes. As of December 31, 2016, the exchangeable senior notes, net had a balance of $108.1 million in the consolidated balance sheets, which was net of an unamortized discount of $1.9 million and $5.0 million of unamortized fair value of the exchange settlement feature, which was included in additional paid-in capital within the consolidated balance sheets. Secured Note Payable In December 2014, as part of the Ellington Portfolio Acquisition, the Company assumed a $51.6 million secured note payable. The debt consists of a 5-year note payable, which is secured by a first priority mortgage on 583 of the homes acquired as part of the Ellington Portfolio Acquisition, bears interest at 4.06%, matures on July 1, 2019, and contains certain required covenants, including a minimum debt service coverage ratio of 1.47 to 1.00. As of December 31, 2016 and 2015, the secured note payable had a balance of $49.8 million and $50.8 million, respectively, in the consolidated balance sheets. Credit facilities In March 2013, the Company entered into a $500.0 million senior secured revolving credit facility with a financial institution, which was subsequently amended in September 2013 to, among other things, expand our borrowing capacity to $800.0 million and extend the repayment period to September 30, 2018. All borrowings under the credit facility accrued interest at 1-month LIBOR plus 2.75% until March 2017, and thereafter at 1-month LIBOR plus 3.125%. The credit facility was secured by our operating partnership’s membership interests in entities that own certain of our single-family properties and required that we maintain certain financial covenants. In July 2016, the Company paid off the $142.0 million of borrowings that had been outstanding on the credit facility, using proceeds from our 6.35% Series E perpetual preferred share offering, and terminated the credit facility in August 2016. The termination of the credit facility resulted in $2.7 million of charges during the third quarter of 2016, related to deferred financing cost write-offs, that were included in loss on early extinguishment of debt within the consolidated statements of operations. In August 2016, the Company entered into a $1.0 billion credit agreement providing for a revolving credit facility in an aggregate principal amount of $650.0 million and a delayed draw term loan facility in an aggregate principal amount of $350.0 million. The interest rate on the revolving credit facility is, at the Company’s election, a LIBOR rate plus a margin ranging from 1.75% to 2.30% or a base rate (generally determined according to a prime rate or federal funds rate) plus a margin ranging from 0.75% to 1.30%. Loans under the term loan facility accrue interest, at the Company’s election, at either a LIBOR rate plus a margin ranging from 1.70% to 2.30% or a base rate plus a margin ranging from 0.70% to 1.30%. In each case, the actual margin is determined according to a ratio of the Company’s total indebtedness to total asset value in effect from time to time. Based on current credit metrics for LIBOR based borrowings as of December 31, 2016, the revolving credit facility bears interest at 1-month LIBOR plus 1.85%, and the term loan facility bears interest at 1-month LIBOR plus 1.80%. 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 facilities mature on August 16, 2019. No amortization payments are required on the term loan facility prior to the maturity date. The Company has the option to extend the maturity date of the revolving credit facility for up to one year, and has two options to extend the maturity date of the term loan facility for up to one year each, in both cases upon payment of an extension fee. The credit agreement requires that we maintain certain financial covenants. As of December 31, 2016, the Company had no outstanding borrowings against the revolving credit facility, $325.0 million of outstanding borrowings against the term loan facility and was in compliance with all loan covenants.
