[7] The Company's unsecured revolving credit facility (the facility) bears interest at LIBOR plus 1.00%, which was 2.49% on December 31, 2017. Interest is payable monthly. On September 27, 2017, the Company amended its unsecured revolving credit facility and its unsecured term loan facility. The amendments to the unsecured revolving portion of the credit facility, among other things, (i) increase the initial maximum available amount from $650.0 million to $1.0 billion, (ii) extend the maturity date from April 24, 2019, to February 27, 2022 (with the Company having the right to extend the loan for an additional seven months) and (iii) lower the interest rate and facility fee pricing based on a grid related to the Company's senior unsecured credit ratings which at closing was LIBOR plus 1.00% and 0.20%, versus LIBOR plus 1.25% and 0.25%, respectively, under the previous terms. In connection with the amendment, $19 thousand of deferred financing costs (net of accumulated amortization) were written off during the year ended December 31, 2017 and are included in costs associated with loan refinancing. As of December 31, 2017, the Company had $210.0 million outstanding under the facility and total availability under the revolving credit facility was $790.0 million. In addition, there is a $1.0 billion accordion feature on the combined unsecured revolving credit and term loan facility that increases the maximum borrowing amount available under the combined facility, subject to lender approval, from $1.4 billion to $2.4 billion.

The gain represents the difference between the carrying value of the note and the amount due at payoff as the note was recorded at fair value upon acquisition and was not anticipated to be paid off in advance of maturity.

[9] On June 30, 2010, the Company issued $250.0 million in senior unsecured notes due on July 15, 2020. The notes bear interest at 7.75%.

On February 28, 2018, the Company redeemed all of the outstanding 7.75% senior notes.

At closing, the Company borrowed the remaining $50.0 million available on the $400.0 million term loan portion of the facility, which was used to pay down a portion of the Company's unsecured revolving credit facility. In addition, there is a $1.0 billion accordion feature on the combined unsecured revolving credit and term loan facility that increases the maximum borrowing amount available under the combined facility, subject to lender approval, from $1.4 billion to $2.4 billion. If the Company exercises all or any portion of the accordion feature, the resulting increase in the facility may have a shorter or longer maturity date and different pricing terms.
