Equity and Debt [Abstract]
SHAREHOLDERS' EQUITY AND DEBT	SHAREHOLDERS’ EQUITY AND DEBT Share repurchases The Company currently has a share repurchase program to repurchase up to $10 million of its common stock pursuant to Rule 10b-18 of the Securities Exchange Act of 1934. In January 2019, the Company's Board of Directors established the current $10 million repurchase program to replace the prior authorizations. During the three months ended March 31, 2020 and March 31, 2019, the Company repurchased 164,876 shares and 121,466, respectively, of common stock for approximately $0.7 million and $0.7 million, respectively. Share purchases and sales During the Company's March 2020 trading window, several members of Cumberland's Board of Directors entered into share purchase agreements of the Company's stock pursuant to Rule 10b-18 of the Securities Exchange Act of 1934. These purchases are designed to increase ownership in the Company by the members of the Board. Share Sale In November 2017, the Company filed a Shelf Registration on Form S-3 with the SEC associated with the sale of up to $100 million in corporate securities. The Shelf Registration was declared effective in January 2018 including an At-The-Market ("ATM") feature enabling the Company to sell shares at market prices. The Company did not issue any shares under the ATM during the three months ended March 31, 2020 or March 31, 2019. Restricted Share Grants During the three months ended March 31, 2020, and March 31, 2019, the Company issued 229,141 shares and 222,269 shares of restricted stock to employees and directors, respectively. Restricted stock issued to employees generally cliff-vests on the fourth anniversary of the date of grant and for directors on the one-year anniversary of the date of grant. Stock compensation expense is presented as a component of general and administrative expense in the condensed consolidated statements of operations and comprehensive income (loss). Cumberland Emerging Technologies In April 2019, Cumberland Emerging Technologies ("CET"), our majority-owned subsidiary, entered into an agreement with WinHealth whereby WinHealth made a $1 million investment through the purchase of shares of CET stock. As part of the agreement, WinHealth obtained a Board position at CET and the first opportunity to license CET products for the Chinese market. In connection with WinHealth's investment in CET, Cumberland also made an additional $1 million investment in CET. Cumberland purchased additional CET shares through contribution of $0.3 million in cash and a conversion of $0.7 million in intercompany loans payable. Upon completion of the additional investment by WinHealth and Cumberland, Gloria Pharmaceuticals agreed to return it's shares in CET in exchange for consideration of $0.8 million. Debt Agreement On May 10, 2019, the Company entered into a third amendment ("Third Amendment") to the Revolving Credit Loan Agreement, dated July 28, 2017, with Pinnacle Bank (“Pinnacle Agreement”). The Third Amendment extended the term of the Pinnacle Agreement through July 31, 2021 as well as modified certain definitions and terms of the existing financial covenants, including the definition of the Funded Debt Ratio and the compliance target of the Tangible Capital Ratio. Both Third Amendment modifications were related to the Vibativ transaction. Under the Pinnacle Agreement, Cumberland was initially subject to one financial covenant, the maintenance of a Funded Debt Ratio, as such term is defined in the agreement and determined on a quarterly basis. On August 14, 2018, the Company amended the Pinnacle Agreement ("First Amendment") to replace the single financial covenant with the maintenance of either the Funded Debt Ratio or a Tangible Capital Ratio, as defined in the First Amendment. The Company was in compliance with the Tangible Capital Ratio financial covenant as of March 31, 2020. The initial revolving line of credit under the Pinnacle Agreement was for up to an aggregate principal amount of $12.0 million with the ability to increase the principal amount available for borrowing up to $20.0 million, upon the satisfaction of certain conditions. On October 17, 2018, the Company entered into a second amendment (“Second Amendment”) which increased the maximum aggregate principal available for borrowing under the Pinnacle Agreement to $20.0 million. The interest rate on the Pinnacle Agreement is based on LIBOR plus an interest rate spread. There is no LIBOR minimum and the LIBOR pricing provides for an interest rate spread of 1.75% to 2.75% (representing an interest rate of 3.73% at March 31, 2020). In addition, a fee of 0.25% per year is charged on the unused line of credit. Interest and the unused line fee are payable quarterly. Borrowings under the line of credit are collateralized by substantially all of our assets. As of March 31, 2020 and December 31, 2019, the Company had $18.5 million in borrowings outstanding under our revolving credit facility.
