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 2016, 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, 2018 and September 30, 2017, the Company repurchased 365,648 shares and 438,715 shares, respectively, of common stock for approximately $2.4 million and $2.9 million, respectively. 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. During the nine months ended September 30, 2018, the Company issued 30,704 shares of common stock for gross proceeds of $0.2 million as part of its At-The-Market (“ATM”) sales agreement with B. Riley FBR. Restricted Share Grants During the nine months ended September 30, 2018, and September 30, 2017, the Company issued 233,330 shares and 233,525 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). Debt Agreement On October 17, 2018, the Company entered into a second amendment (“Second Amendment”) to the Revolving Credit Loan Agreement, dated July 28, 2017, with Pinnacle Bank (“Pinnacle Agreement”). The Second Amendment increases the maximum aggregate principal available for borrowing under the Pinnacle Agreement to $20 million. Cumberland increased the maximum aggregate principal available for borrowing to support potential future acquisitions and general corporate purposes. The initial revolving line of credit under the Pinnacle Agreement was for up to an aggregate principal amount of $12 million with the ability to increase the principal amount available for borrowing up to $20 million, upon the satisfaction of certain conditions. The Second Amendment does not affect the term of the Pinnacle Agreement, which has a three year term expiring on July 31, 2020. The Pinnacle Agreement replaced the June 2014 Revolving Credit Loan Agreement with SunTrust Bank, which was to expire on June 30, 2018. The Company had $12.0 million in borrowings under the Pinnacle Agreement at September 30, 2018 and $9.8 million at December 31, 2018. 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% (resulting in an interest rate of 4.0% at September 30, 2018). 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. 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 covenant as of September 30, 2018.
