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, 2021 and September 30, 2020, the Company repurchased 326,537 shares and 407,683 shares, respectively, of common stock for approximately $1.0 million and $1.5 million, respectively. At September 30, 2021, approximately $5.2 million of common shares was left to repurchase under this program. Share purchases and sales During the Company's March 2021 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 Sales 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. It also included an At the Market ("ATM") feature that allowed the Company to sell common shares at market prices, along with an agreement with B. Riley FBR Inc. to support such a placement of shares. The Company filed an updated Form S-3 with the SEC in December 2020, which was declared effective in January 2021. The Company does not currently have an ATM feature in place. Cumberland plans to continue to evaluate the market for its common shares, and if favorable, will further evaluate whether or not to enter into an ATM feature through B. Riley FBR, Inc. that would allow the Company to issue shares of its common stock. The Company did not issue any shares under an ATM during the nine months ended September 30, 2021 or September 30, 2020. Restricted Share Grants and Incentive Stock Options During the nine months ended September 30, 2021 and September 30, 2020, the Company issued 36,850 shares and 230,491 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. During the nine months ended September 30, 2021, the Company also issued 174,800 incentive stock options to employees that cliff-vest on the fourth anniversary of the date of grant, that are set to expire in March and May 2031. Stock compensation expense is presented as a component of general and administrative expense in the condensed consolidated statements of operations. Debt Agreement On October 28, 2021, the Company and Pinnacle Bank entered into a Fourth Amendment to the Revolving Credit Note and Fifth Amendment ("Fifth Amendment") to the Revolving Credit Loan Agreement to renew the Revolving Credit Loan. The original Pinnacle Agreement was dated July 2017. Beginning on August 14, 2018, and continuing until October 7, 2020, the Company and Pinnacle Bank entered into a series of amendments to extend and update the Revolving Credit Note and Revolving Credit Agreement. The most recent amendment dated October 28, 2021, extends the maturity date three years through October 1, 2024. Consistent with prior Amendments, the Fifth Amendment provides for a principal balance available for borrowing of up to $15 million. The Company has the right to request an increase of up to an additional $5 million providing a maximum principal available of up to $20 million upon the satisfaction of certain conditions and with the approval of Pinnacle Bank. Also consistent with prior Amendments, the Company is required to maintain either a Funded Debt Ratio covenant or a Tangible Capital Ratio covenant. 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 3.65% at September 30, 2021. 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. As of September 30, 2021 and December 31, 2020, the Company had $15.0 million in borrowings outstanding under its revolving credit facility. The Company was in compliance with the Tangible Capital Ratio financial covenant as of September 30, 2021. Borrowings under the line of credit are collateralized by substantially all of our assets. Paycheck Protection Program Loan On April 20, 2020, Cumberland received the funding of a loan from Pinnacle Bank in the 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"). Pursuant to the PPP requirements, loan funds were used to maintain payroll, continue group health care benefits, and pay for rent and utilities during the pandemic. We applied for this loan after carefully considering, with our bank, the eligibility criteria to participate in this program, and determining that Cumberland met those criteria. We evaluated and provided information on our payroll and other qualifying expenses to determine the amount of PPP funds to apply for. 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. Cumberland used the PPP loan funds for such qualifying expenses. Due to assistance from our PPP loan, the Company did not lay off or furlough any employees as a result of the COVID-19 pandemic. Cumberland 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 a result, the Company recorded the $2,187,140 as a deferred income liability, which was included as a component of other current liabilities on the condensed consolidated balance sheet at December 31, 2020. In October 2020, Cumberland submitted a request for the loan’s forgiveness. On June 11, 2021, the Company received a formal notice from the SBA that the full amount of the loan was forgiven. The Company accounted for the forgiveness of the PPP loan under IAS 20 and recorded the $2,187,140 as other income. 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 a $0.2 million convertible note, which was funded during the first quarter 2021. 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.
