Long-Term Debt

Credit Facilities

On March 10, 2016, we entered into a secured credit facility with Wells Fargo Bank, N.A. as Administrative Agent, consisting of a maximum $65.0 million revolving credit facility and a $45.0 million term loan facility (together the "2016 Secured Credit Facility"). The 2016 Secured Credit Facility was secured by substantially all of our assets and material domestic subsidiaries. The 2016 Secured Credit Facility was used for general corporate purposes, and to replace and repay outstanding borrowings.

Prepayment of the 2016 Secured Credit Facility was required upon the completion of the sale of Trillium in accordance with its terms. The proceeds of the Trillium sale were used to repay in full all outstanding loans, together with interest, and all other amounts due in connection with repayment. Prepayment penalties of approximately $1.3 million were incurred as a result of repaying the 2016 Secured Credit Facility. The credit and guarantee agreements related to the 2016 Secured Credit Facility were likewise terminated.

On April 17, 2017, we entered into a secured credit facility with Texas Capital Bank, N.A., that provides a $20 million revolving credit facility (the "Texas Capital Credit Facility"). The Texas Capital Credit Facility is being used for general corporate purposes and to provide collateral for letters of credit issued by Texas Capital Bank up to $5.0 million. The Texas Capital Credit Facility is secured by substantially all assets of the company and its material domestic subsidiaries. The Texas Capital Credit Facility is secured by HHS Guaranty, LLC, an entity formed to provide credit support for Harte Hanks by certain members of the Shelton family (descendants of one of our founders).

The Texas Capital Credit Facility expires on April 16, 2019, at which point all outstanding principal amounts will be due. Harte Hanks can elect to accrue interest on outstanding principal balances at either LIBOR plus 1.95% or prime less 0.75%. Unused credit balances will accrue interest at 0.50%. Harte Hanks is required to pay a quarterly fee of $0.1 million as consideration for the collateral balances provided by HHS Guaranty, LLC.

The Texas Capital Credit Facility is subject to customary covenants requiring insurance, legal compliance, payment of taxes, prohibition of second liens, and secondary indebtedness, as well as the filing of quarterly and annual financial statements.

Our long-term debt obligations were as follows:

Based on the recent entry into the Texas Capital Credit Facility, carrying values estimate fair value. These current rates are considered Level 2 inputs under the fair value hierarchy established by ASC 820, Fair Value Measurement, as they are based upon information obtained from third party banks.

At June 30, 2017, we had letters of credit in the amount of $4.1 million backed by cash collateral. No amounts were drawn against these letters of credit at June 30, 2017. These letters of credit exist to support insurance programs relating to workers’ compensation, automobile, and general liability, and to offset liability relating to leasehold obligations. The cash collateral used in the existing letters of credit are not included as part of the Texas Capital Credit Facility and do not decrease the availability on the remaining capacity.
