Change in Fair Value of Contingent Consideration.In connection with the acquisition of Greater Media, a certain number of shares of our Class A common stock placed in escrow on the acquisition date were forfeited based on a working capital adjustment. The fair value of the forfeited shares decreased $2.9 million due to a change in our stock price from January 1, 2018 to March 15, 2018, the date the forfeited shares were recorded in treasury stock. In addition, a number of shares of our Class A common stock were returned to us by the former stockholders of Greater Media based on certain proceeds from the sale of Greater Media’s tower assets. The fair value of the returned shares decreased $1.6 million due to a change in our stock price from January 1, 2018 to March 15, 2018, the date the returned shares were recorded in treasury stock.
Gain on Dispositions.On March 28, 2019, we completed the sale of certain land and improvements in Augusta, GA for $0.5 million. As a result of the sale, we recorded a gain of $0.4 million in the six months ended June 30, 2019. On March 15, 2019, we agreed to cancel a broadband radio service license in Chattanooga, TN in exchange for a fee of $3.3 million. As a result of the license cancelation, we recorded a gain of $3.1 million in the six months ended June 30, 2019.
Interest Expense. Interest expense increased $1.7 million during the six months ended June 30, 2019 as compared to the six months ended June 30, 2018. The primary factors affecting interest expense were the increase in long-term debt outstanding and the applicable interest rate.
Income Tax Expense.Our effective tax rate was 57% and 31% for the six months ended June 30, 2018 and 2019, respectively. These rates differ from the federal statutory rate of 21% due to the effect of state income taxes and certain expenses that are not deductible for tax purposes. The effective tax rate for the six months ended June 30, 2018 also reflects a $1.2 million increase due to the change in fair value of contingent consideration during that time period.
Net Income. Net income during the six months ended June 30, 2019 was $5.6 million, an increase of $3.9 million compared to net income of $1.8 million during the six months ended June 30, 2018 as a result of the factors described above.
Liquidity and Capital Resources
Overview. Our primary sources of liquidity are internally generated cash flow and our revolving credit facility. Our primary liquidity needs have been, and for the next twelve months and thereafter, are expected to continue to be, for working capital, debt service, and other general corporate purposes, including capital expenditures and radio station acquisitions. Historically, our capital expenditures have not been significant. In addition to property and equipment associated with radio station acquisitions, our capital expenditures have generally been, and are expected to continue to be, related to the maintenance of our office and studio space, maintenance of our radio towers and equipment, and digital products and information technology. We have also purchased or constructed office and studio space in some of our markets to facilitate the consolidation of our operations.
Credit Facility. On November 17, 2017 we and our wholly owned subsidiary, Beasley Mezzanine Holdings, LLC (the “Borrower”), entered into a credit agreement with U.S. Bank, National Association, as administrative agent and collateral agent, providing for a term loan B facility in the amount of $225.0 million (the “term loan facility”) and a revolving credit facility of $20.0 million (the “revolving credit facility,” and together with the term loan facility, the “credit facility”). On September 27, 2018, we borrowed an additional $35.0 million from the term loan facility. The proceeds were used for the acquisition ofWXTU-FM in Philadelphia.
As of June 30, 2019, the credit facility consisted of a term loan with a remaining balance of $245.5 million and a revolving credit facility with a maximum commitment of $20.0 million. As of June 30, 2019, we had $20.0 million in available commitments under our revolving credit facility. At our option, the credit facility may bear interest at either (i) the London Interbank Offered Rate (“LIBOR”) plus a margin of 4.0% or (ii) the base rate plus a margin of 3.0%. The LIBOR interest rate for the term loan is subject to a 1% floor and the base rate is subject to a 2% floor. Interest payments are, for loans based on LIBOR, due at the end of each applicable interest period unless the interest period is longer than three months, in which case they are due at the end of each three month period. Interest payments for loans based on the base rate are due quarterly. The revolving credit facility carried interest, based on LIBOR, at 6.4% as of June 30, 2019 and matures on November 17, 2022. The term loan carried interest, based on LIBOR, at 6.4% as of June 30, 2019 and matures on November 1, 2023.
The credit agreement requires mandatory prepayments equal to 50% of Excess Cash Flow (as defined in the credit agreement) when our Total Leverage Ratio (as defined in the credit agreement) is greater than 3.5x; mandatory prepayments equal to 25% of Excess Cash Flow when our Total Leverage Ratio is less than or equal to 3.5x but greater than 3.0x; and no mandatory prepayments when our Total Leverage Ratio is less than or equal to 3.0x. Mandatory prepayments of Excess Cash Flow are due 95 days after year end. The credit agreement also requires mandatory prepayments for defined amounts from net proceeds of asset sales, net insurance proceeds, and net proceeds of debt issuances.
