Debt Disclosure [Abstract] |
CREDIT FACILITIES | 5. CREDIT FACILITIES Credit Agreement We have a $40.0 million revolving credit facility with Hancock Whitney Bank ("Credit Agreement") that can be used for borrowings or letters of credit that matures June 9, 2021. On February 28, 2020, we amended our Credit Agreement to amend our financial covenants. Our amended quarterly financial covenants at December 31, 2019, and for the remaining term of the Credit Agreement, are as follows:
| • | Ratio of current assets to current liabilities of not less than 1.25:1.00;
| • | Minimum tangible net worth of at least the sum of $130.0 million, plus 100% of the proceeds from any issuance of stock or other equity after deducting of any fees, commissions, expenses and other costs incurred in such offering;
| • | Minimum cash, cash equivalents and short-term investments of $40.0 million; and
| • | Ratio of funded debt to tangible net worth of not more than 0.50:1.00.
Our Credit Agreement also includes restrictions regarding our ability to: (i) grant liens; (ii) make certain loans or investments; (iii) incur additional indebtedness or guarantee other indebtedness in excess of specified levels; (iv) make any material change to the nature of our business or undergo a fundamental change; (v) make any material dispositions; (vi) acquire another company or all or substantially all of its assets; (vii) enter into a merger, consolidation, or sale leaseback transaction; or (viii) declare and pay dividends if any potential default or event of default occurs. Interest on borrowings under the Credit Agreement may be designated, at our option, as either the Wall Street Journal published Prime Rate (4.75% at December 31, 2019) or LIBOR (1.76% at December 31, 2019) plus 2.0% per annum. Commitment fees on the unused portion of the Credit Agreement are 0.4% per annum and interest on outstanding letters of credit is 2.0% per annum. The Credit Agreement is secured by substantially all of our assets (with a negative pledge on our real property). At December 31, 2019, we had no outstanding borrowings under our Credit Agreement and $10.2 million of outstanding letters of credit to support our projects, providing $29.8 million of available capacity. At December 31, 2019, we were in compliance with all of our amended financial covenants, with a tangible net worth of $153.4 million (as defined by the Credit Agreement); total cash, cash equivalents and short-term investments of $69.6 million; a ratio of current assets to current liabilities of 1.67 to 1.0; and a ratio of funded debt to tangible net worth of 0.07:1.00. Surety Bonds We issue surety bonds in the ordinary course of business to support our projects. At December 31, 2019, we had $409.9 million of outstanding surety bonds.
