PART II Note 10.
Debt Bank Line of Credit and Term Loans The Company’s $2.0 billion unsecured revolving line of credit facility (the “Facility”) matures on October 19, 2021 and contains two, six-month extension options.
Borrowings under the Facility accrue interest at LIBOR plus a margin that depends upon the Company’s credit ratings.
The Company pays a facility fee on the entire revolving commitment that depends on its credit ratings.
Based on the Company’s credit ratings at December?31, 2018, the margin on the Facility was 0.875%, and the facility fee was 0.15%.
The Facility also includes a feature that allows the Company to increase the borrowing capacity by an aggregate amount of up to $750 million, subject to securing additional commitments.
At December?31, 2018, the Company had $80 million, including ￡55 million ($70 million), outstanding under the Facility with a weighted average effective interest rate of 2.12%.
In March 2017, the Company repaid a ￡137 million unsecured term loan.
?On June 30, 2017, the Company repaid ￡51 million of its four-year unsecured term loan entered into in January 2015 (the “2015 Term Loan”).
Concurrently, the Company terminated its three-year interest rate swap which fixed the interest of the 2015 Term Loan and therefore, beginning June 30, 2017, the 2015 Term Loan accrued interest at a rate of GBP LIBOR plus 1.15%, subject to adjustments based on the Company’s credit ratings.
On July 3, 2018, the Company exercised its one-time right to repay the outstanding GBP balance and re-borrow in USD with all other key terms unchanged, which resulted in repayment of the ￡169 million balance and re-borrowing of $224 million.
In November 2018, the Company repaid the $224 million unsecured term loan, bringing the total term loan balance to zero as of December?31, 2018.
The Facility contains certain financial restrictions and other customary requirements, including cross-default provisions to other indebtedness.
Among other things, these covenants, using terms defined in the agreements: (i)?limit the ratio of Consolidated Total Indebtedness to Consolidated Total Asset Value to 60%, (ii)?limit the ratio of Secured Debt to Consolidated Total Asset Value to 30%, (iii)?limit the ratio of Unsecured Debt to Consolidated Unencumbered Asset Value to 60%; (iv)?require a minimum Fixed Charge Coverage ratio of 1.5 times; and (v) require a Minimum Consolidated Tangible Net Worth of $6.5 billion at December?31, 2018.
At December?31, 2018, the Company believes it was in compliance with each of these restrictions and requirements of the Facility.
Senior Unsecured Notes At December?31, 2018, the Company had senior unsecured notes outstanding with an aggregate principal balance of $5.3 billion.
The senior unsecured notes contain certain covenants including limitations on debt, maintenance of unencumbered assets, cross-acceleration provisions and other customary terms.
The Company believes it was in compliance with these covenants at December?31, 2018.
The following table summarizes the Company’s senior unsecured notes payoffs for the periods presented (dollars in thousands):
## Table 0 ##
(1) The Company recorded a $44 million loss on debt extinguishment related to the repurchase of senior notes.
(2) The Company recorded a $54 million loss on debt extinguishment related to the repurchase of senior notes.
(3) The Company recorded a $46 million loss on debt extinguishment related to the repurchase of senior notes.
There were no senior unsecured notes issuances for the years ended December?31, 2018, 2017, and 2016.
PART II 2017 and 2016 On October 31, 2016, we completed the Spin-Off of QCP.
The Spin-Off included 338 properties, primarily comprised of the HCR ManorCare, Inc.  (“HCRMC”) DFL investments and an equity investment in HCRMC.
The following table summarizes results for the years ended December 31, 2017 and 2016 (dollars in thousands):
## Table 1 ##
Net income (loss) decreased primarily as a result of the following: ?
a reduction in net income from discontinued operations due to the Spin-Off of QCP on October 31, 2016; ?
a loss on debt extinguishment in July 2017, representing a premium for early payment on the repurchase of our senior notes; ?
a reduction in rental and related revenues primarily as a result of assets sold during 2017, including the sale of 64 senior housing triple-net assets in the first quarter of 2017; ?

The decrease in net income (loss) was partially offset by: ?
a reduction in interest expense as a result of debt repayments in the fourth quarter of 2016 and throughout 2017; ?
a reduction in severance and related charges primarily related to the departure of our former President and Chief Executive Officer (“CEO”) in 2016 compared to severance and related charges primarily related to the departure of our former CAO in 2017; ?
a larger net gain on sales of real estate during 2017 compared to 2016, primarily related to the sale of 64?senior housing triple-net assets and the partial sale of?RIDEA II during 2017; ?
