SHAREHOLDERS’ EQUITY AND DEBT
Share Repurchases
On May 13, 2010, the Company announced a share repurchase program to purchase up to $10.0 million of its common stock pursuant to Rule 10b-18 of the Securities Act. In January 2011, April 2012 and January 2013, the Company's Board of Directors replaced the prior authorizations with new $10.0 million authorizations for repurchases of the Company's outstanding common stock. During the nine months ended September 30, 2014 and the nine months ended September 30, 2013, the Company repurchased 576,978 shares and 828,551 shares of common stock for approximately $2.7 million and $3.9 million, respectively.
Restricted Share Grants
During the first nine months of 2014, the Company issued approximately 193,000 shares of restricted stock to employees and directors. Restricted stock issued to employees generally cliff-vests on the fourth anniversary of the date of grant. Restricted stock issued to directors vests 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.
Cumberland Emerging Technologies
In April 2014, the Company received approximately $1.0 million from Gloria for its participation in Cumberland Emerging Technologies ("CET"). As a result, Gloria received shares in CET and will have the first right to negotiate a license to CET developed products for the Chinese market. Prior to April 2014, Cumberland owned 85% of CET, with the balance of the enterprise being owned by Vanderbilt University and the Tennessee Technology Development Corporation. In connection with Gloria’s investment in CET, the Company also provided an additional investment in CET. Cumberland contributed $1.0 million in cash and provided $2.4 million in loan foregiveness to CET in exchange for newly issued shares. Upon completion of the additional investment by Gloria and Cumberland in April 2014, the Company’s ownership in CET is 80%. As a consolidated subsidiary, the Company reports the operating results of CET and allocates the noncontrolling interests to the non-majority partners.

New Debt Agreement
On June 26, 2014, Cumberland entered into a Revolving Credit Loan Agreement (“Loan Agreement”) with SunTrust Bank. The new agreement replaced the August 2011 Fifth Amended and Restated Loan Agreement (the "Agreement") with its previous lender which was to expire on December 31, 2014. There are no borrowings under the Loan Agreement at September 30, 2014, and it has a three year term expiring on June 26, 2017. The Loan Agreement provides for an aggregate principal amount up to $20 million. The initial revolving line of credit is up to $12 million, an increase from the $10 million under the previous Agreement. Similar to the previous Agreement, Cumberland has the ability to increase the borrowing amount up to $20 million, upon the satisfaction of certain conditions.
The interest rate on the Loan 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 1.0% to 2.85%. 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 the Company’s assets.
Under the Loan Agreement, Cumberland is subject to certain financial covenants, including, but not limited to, maintaining an EBIT to Interest Expense Ratio and a Funded Debt Ratio, as such terms are defined in the Loan Agreement and that are determined on a quarterly basis. The Company is in compliance with all covenants at September 30, 2014.
The Company incurred no early termination penalties upon termination of the previous Agreement and incurred approximately $0.1 million in deferred financing costs related to the new Loan Agreement, which will be amortized to interest expense using the effective interest method over the term of the Loan Agreement.
