Equity and Debt [Abstract]
SHAREHOLDERS' EQUITY AND DEBT	SHAREHOLDERS’ EQUITY AND DEBT Share repurchases Cumberland 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 nine months ended September 30, 2020 and September 30, 2019, the Company repurchased 407,683 shares and 452,155, respectively, of common stock for approximately $1.5 million and $2.6 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. During the nine months ended September 30, 2020, a total of 10,080 shares have been purchased. Share Sale In November 2017, Cumberland 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 nine months ended September 30, 2020 or September 30, 2019. Restricted Share Grants During the nine months ended September 30, 2020, and September 30, 2019, the Company issued 230,491 shares and 225,869 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. Cumberland Emerging Technologies In April 2019, Cumberland Emerging Technologies ("CET"), our majority-owned subsidiary, entered into an agreement whereby Hongkong WinHealth Pharma Group Ltd. ("WinHealth") made a $1 million investment in CET through the purchase of shares of its common stock. As part of the agreement, WinHealth obtained the rights to name an individual for appointment to the CET Board of Directors as well as the first opportunity to license CET products for the Chinese market. In connection with WinHealth's investment in CET, during 2019, Cumberland also made an additional $1 million investment in CET. Cumberland purchased additional CET common 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 returned its shares in CET in exchange for $0.8 million that was funded during 2020. Debt Agreement On October 7, 2020, the Company entered into a Third Amendment to the Revolving Credit Note and Fourth Amendment (“Fourth Amendment”) to the Revolving Credit Loan Agreement with Pinnacle Bank (the “Pinnacle Agreement”). The original Pinnacle Agreement was dated July 2017. The Fourth Amendment provides for a principal available for borrowing of up to $15 million and Cumberland has the ability to request an increase of up to an additional $5 million, upon the satisfaction of certain conditions and approval by Pinnacle Bank. If fully expanded, the Fourth Amendment would provide a maximum principal available for borrowing of up to $20 million, which was also the maximum aggregate principal available for borrowing under the previously amended Pinnacle Agreement. The Fourth Amendment extends the maturity date of the Pinnacle Agreement through October 1, 2022. On May 10, 2019, the Company entered into a third amendment ("Third Amendment") to the 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 September 30, 2020. The interest rate on the Pinnacle Agreement is based on LIBOR plus an interest rate spread. The pricing under the Fourth Amendment provides for an interest rate spread of 1.75% to 2.75% above LIBOR with a minimum LIBOR of 0.90%. The applicable interest rate under the Pinnacle Agreement was 2.90% at September 30, 2020, prior to entering into the Fourth Amendment. 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 September 30, 2020 and December 31, 2019, the Company had $17.0 million and $18.5 million in borrowings outstanding under our revolving credit facility, respectively. Of the $17.0 million in borrowings outstanding at September 30, 2020, $2.0 million is classified as current based on the terms of the Fourth Amendment. Paycheck Protection Program Loan On April 20, 2020, Cumberland received the funding of a loan from Pinnacle Bank in the aggregate amount of $2,187,140 pursuant to the Paycheck Protection Program (the “PPP”) under the Federal Coronavirus Aid, Relief, and Economic Security Act ("CARES Act"), which was enacted March 27, 2020. The PPP is administered by the U.S. Small Business Administration ("SBA"). The loan matures April 14, 2022, and bears interest at a rate of 1.0% per year, payable monthly commencing during November 2020. The loan may be prepaid at any time prior to maturity with no prepayment penalties. Funds from the loan are to be used to maintain payroll, continue group health care benefits and pay for rent and utilities. Under the terms of the PPP, certain amounts of the loan may be forgiven if they are used for qualifying expenses as described in the CARES Act, including qualifying payroll costs, covered rent payments, and covered utilities. From the date of funding the Company has used the loan amount for such qualifying expenses. Cumberland has elected to account for the proceeds of the loan as a government grant under International Accounting Standard 20 ("IAS 20"), Accounting for Government Grants and Disclosure of Government Assistance. The permitted analogous use of IAS 20 outlines a model for the accounting for government assistance, including forgivable loans. As result, the Company has recorded the $2,187,140 as a deferred income liability, which is included as a component of other current liabilities on the condensed consolidated balance sheet. The Company intends to apply IAS 20 to the PPP loan forgiveness and has presented the amounts expected to be forgiven as deferred income. The Company will account for the anticipated forgiveness of the PPP loan under IAS 20 when the Company believes that the forgiveness is reasonably assured. Cumberland applied for this loan after carefully considering, with its bank, the eligibility criteria to participate in this program, and determining that Cumberland met these criteria. The Company evaluated and provided information on our payroll and other qualifying expenses to determine the amount of PPP funds to apply for. Cumberland has not laid off or furloughed any employees as a result of the COVID-19 pandemic and, based on assistance from the PPP loan, the Company currently does not foresee doing so. In October 2020, the Company submitted a request for forgiveness of the PPP loan. The request was approved by the lender, Pinnacle Bank, who then submitted it to SBA for the SBA's review and approval. Joint Venture Agreement In August 2020, Cumberland entered into an agreement with WinHealth Investment (Singapore) Ltd creating WHC Biopharmaceuticals, Pte. Ltd. The joint venture, as a limited liability company, will focus on acquiring, developing, registering, and commercializing development stage and commercial stage biopharmaceuticals for China, Hong Kong and other Asian markets. The agreement provides for initial investment from WinHealth in the form of a $0.2 million equity contribution and an initial investment from Cumberland in the form of $0.2 million convertible note. The joint venture will seek additional future capital from additional investors and has entered into exclusive option agreements to license intellectual property from both Cumberland Pharmaceuticals Inc. and Cumberland Emerging Technologies.
