In 2016, we reduced the revolving commitment provided by our senior secured credit facility, which matures on May 15, 2017 (with two one-year extension options), from $300,000,000 to $125,000,000, none of which was drawn at year-end 2016. The revolving line of credit may be prepaid at any time without penalty. The revolving line of credit includes a $100,000,000 sublimit for letters of credit, of which $14,850,000 was outstanding at year-end 2016. Total borrowings under our senior secured credit facility (including the face amount of letters of credit) may not exceed a borrowing base formula. At year-end 2016, we had $71,262,000 in net unused borrowing capacity under our senior credit facility.

Under the terms of our senior secured credit facility, at our option, we can borrow at LIBOR plus 4.0 percent or at the alternate base rate plus 3.0 percent. The alternate base rate is the highest of (i) KeyBank National Association’s base rate, (ii) the federal funds effective rate plus 0.5 percent or (iii) 30 day LIBOR plus 1 percent. Borrowings under the senior secured credit facility are or may be secured by (a) mortgages on the timberland, high value timberland and portions of raw entitled land, as well as pledges of other rights including certain oil and gas operating properties, (b) assignments of current and future leases, rents and contracts, (c) a security interest in our primary operating account, (d) a pledge of the equity interests in current and future material operating subsidiaries and most of our majority-owned joint venture interests, or if such pledge is not permitted, a pledge of the right to distributions from such entities, and (e) a pledge of certain reimbursements payable to us from special improvement district tax collections in connection with our Cibolo Canyons project. The senior secured credit facility provides for releases of real estate and other collateral provided that borrowing base compliance is maintained.

Our debt agreements contain financial covenants customary for such agreements including minimum levels of interest coverage and limitations on coverage. At year-end 2016, our tangible net worth requirement was $426,312,000 computed as: $379,044,000 plus 85 percent of the aggregate net proceeds received by us from any equity offering, plus 75 percent of all positive net income, on a cumulative basis since third quarter 2015. At year-end 2016, we were in compliance with the financial covenants of these agreements.

We may elect to make distributions to stockholders so long as the total leverage ratio is less than 40 percent, the interest coverage ratio is greater than 3.0:1.0 and available liquidity is not less than $125,000,000, all of which were satisfied at year-end 2016. Regardless of whether the foregoing conditions are satisfied, we may make distributions in an aggregate amount not to exceed $50,000,000 to be funded from up to 65% of the net proceeds from sales of multifamily properties and non-core assets, such as the Radisson Hotel & Suites in Austin, and any oil and gas properties.

In 2014, we issued $250,000,000 aggregate principal of 8.5% Senior Secured Notes due 2022 (Notes). The Notes will mature on June 1, 2022 and interest on the Notes is payable semiannually at a rate of 8.5 percent per annum in arrears. In 2016, we completed a cash tender offer for our Notes, pursuant to which we purchased $215,495,000 principal amount (representing approximately 97.6% outstanding) of the Notes. Total consideration paid was $245,604,000, which included $29,091,000 in premium at 113.5% and $1,018,000 in accrued and unpaid interest. In addition, we received consent from holders of the Notes to eliminate or modify certain covenants, events of default and other provisions contained in the indenture governing the Notes, and to release the subsidiary guarantees and collateral securing the Notes. We also purchased $9,750,000 principal amount of the Notes between 99% and 99.95% of face value in open market transactions. The 2016 tender offer and open market purchases resulted in a $35,681,000 loss on extinguishment of debt, which includes the premium paid to repurchase the Notes, write-off of unamortized debt issuance costs of $5,416,000 and $1,301,000 in other costs related to tender offer advisory services.

In 2015, we purchased $19,440,000 principal amount of Notes at 97% of face value, resulting in a gain of $589,000 on the early extinguishment of the retired Notes, offset by the write-off of unamortized debt issuance costs of $506,000 allocated to the retired Notes.

In 2013, we issued $125,000,000 aggregate principal amount of 3.75% convertible senior notes due 2020 (Convertible Notes). Interest on the Convertible Notes is payable semiannually at a rate of 3.75 percent per annum and they mature on March 1, 2020. The Convertible Notes have an initial conversion rate of 40.8351 per $1,000 principal amount. The initial conversion rate is subject to adjustment upon the occurrence of certain events. Prior to November 1, 2019, the Convertible Notes are convertible only upon certain circumstances, and thereafter are convertible at any time prior to the close of business on the second scheduled trading day prior to maturity. If converted, holders will receive cash, shares of our common stock or a combination thereof at our election. We intend to settle the principal amount of the Convertible Notes in cash upon conversion, with any excess conversion value to be settled in shares of our common stock. At year-end 2016, unamortized debt discount of our Convertible Notes was $13,809,000.

In 2016, we purchased $5,000,000 of 3.75% Convertible Senior Notes due 2020 at 93.25% of face value in open market transactions for $4,663,000 and we allocated $4,452,000 to extinguish the debt and $211,000 to reacquire the equity component within the convertible notes based on the fair value of the debt component. We recognized a $110,000 loss on extinguishment of debt based on the difference between the fair value of the debt component prior to conversion and the carrying value of the debt component. Total loss on extinguishment of debt including write-off of debt issuance costs allocated to the repurchased notes was $183,000.

In 2013, we issued $150,000,000 aggregate principal amount of 6.00% tangible equity units (Units). The total offering was 6,000,000 Units, including 600,000 exercised by the underwriters, each with a stated amount of $25.00. Each Unit is comprised of (i) a prepaid stock purchase contract to be settled by delivery of a number of shares of our common stock, par value $1.00 per share to be determined pursuant to a purchase contract agreement, and (ii) a senior amortizing note due December 15, 2016 that has an initial principal amount of $4.2522, bears interest at a rate of 4.50% per annum and has a final installment payment date of December 15, 2016. On December 15, 2016, we made the final installment payment of principal and accrued interest and issued 7,857,000 shares upon settlement of the stock purchase contract based on the applicable market value, as defined in the purchase contract agreement associated with issuance of the Units.

In 2016, a secured promissory note of $15,400,000 was paid in full in connection with sale of the Radisson Hotel & Suites, for $130,000,000.

In 2016, other indebtedness decreased principally as a result of selling Eleven, a 257-unit multifamily project in Austin, for $60,150,000 and paying in full the associated debt of $23,936,000.

At year-end 2016 and 2015, we have $1,633,000 and $8,267,000 in unamortized deferred fees which were deducted from our debt. In addition, at year-end 2016 and 2015, unamortized deferred financing fees related to our senior credit facility included in other assets were $314,000 and $2,768,000. Amortization of deferred financing fees was $3,598,000 in 2016, $4,002,000 in 2015 and $3,845,000 in 2014 and is included in interest expense.

Debt maturities during the next five years are: 2017 — $0; 2018 — $485,000; 2019 — $0; 2020 — $104,673,000; 2021 — $0 and thereafter — $5,200,000.
