4. CREDIT FACILITIES AND DEBT

Credit Agreement

We have a $40.0 million revolving credit facility (“Credit Agreement”) with Hancock Whitney Bank ("Whitney Bank") that can be used for borrowings or letters of credit. On February 28, 2020, we amended our Credit Agreement to amend certain financial covenants, and on August 3, 2020, we further amended our Credit Agreement to, among other things, extend its maturity date from June 9, 2021 to June 30, 2022. Our quarterly financial covenants at June 30, 2020, are as follows:

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 (3.25% at June 30, 2020) or LIBOR (0.18% at June 30, 2020) plus 2.0% per annum; provided, that in connection with the most recent amendment to the Credit Agreement, LIBOR shall not be less than 1.0%. 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 June 30, 2020, we had no outstanding borrowings under our Credit Agreement and $9.8 million of outstanding letters of credit to support our projects, providing $30.2 million of available capacity. At June 30, 2020, we were in compliance with all of our financial covenants, with a tangible net worth of $154.1 million as defined by the Credit Agreement; total cash, cash equivalents and short-term investments of $69.2 million; a ratio of current assets to current liabilities of 1.76:1.00; and a ratio of funded debt to tangible net worth of 0.13:1.00.

Loan Agreement

On April 17, 2020, we entered into an unsecured loan in the aggregate amount of $10.0 million (“PPP Loan”) with Whitney Bank pursuant to the Paycheck Protection Program (“PPP”), which is sponsored by the Small Business Administration (“SBA”), and is part of the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”), as amended by the Paycheck Protection Program Flexibility Act of 2020 (“Flexibility Act”). The PPP provides for loans to qualifying businesses, the proceeds of which may only be used for payroll costs, rent, utilities, mortgage interest, and interest on other pre-existing indebtedness (the “Permissible Expenses”).  The PPP Loan matures on April 17, 2022, bears interest at a fixed rate of 1.0 percent per annum and is payable in monthly installments commencing on the earlier of the date on which the amount of loan forgiveness is determined or March 17, 2021. The PPP Loan may be prepaid at any time prior to maturity with no prepayment penalties.  The PPP Loan, and accrued interest, may be forgiven partially or in full, if certain conditions are met.  The most significant of the conditions are:

In order to obtain forgiveness of the PPP Loan, in whole or in part, we must request forgiveness and provide satisfactory documentation in accordance with applicable SBA guidelines.  During the Covered Period the PPP Loan proceeds were used only for Permissible Expenses, of which approximately 94% was related to payroll costs.  As of the date of this Report, neither Whitney Bank, nor the SBA, are accepting loan forgiveness applications. Any portion of the PPP Loan that is not forgiven, together with accrued interest, will be repaid based on the terms and conditions of the PPP Loan and in accordance with the PPP as amended by the Flexibility Act, unless the SBA were to determine that we were not eligible to participate in the PPP, in which case the SBA could seek immediate repayment of the PPP Loan. While we believe we are a qualifying business and have met the eligibility requirements for the PPP Loan, and believe we have used the loan proceeds only for Permissible Expenses, we can provide no assurances that we will be eligible for forgiveness of the PPP Loan, in whole or in part. Further, the PPP Loan and our loan forgiveness application will be subject to review and potential audit by the SBA.  Accordingly, we have recorded the full amount of the PPP Loan as debt, which is included in long-term debt, current and long-term debt, noncurrent on our Balance Sheet at June 30, 2020.  The current and noncurrent debt classification is based on the terms and conditions of the PPP Loan and in accordance with the PPP as amended by the Flexibility Act, and timing of required repayment absent any loan forgiveness.  We intend to reflect the benefit of any loan forgiveness if, and when, our loan forgiveness application is submitted to, and approved by, the SBA and we have reasonable assurance from the SBA that we have met the eligibility and loan forgiveness requirements of the PPP.

We received a consent from Whitney Bank that allows the PPP Loan to be included as permitted debt under our debt covenants in our Credit Agreement (discussed above) subject to, among other things, compliance with the CARES Act, as amended by the Flexibility Act, and use of the PPP Loan proceeds only for Permissible Expenses and in a manner intended to maximize our entitlement to forgiveness of the PPP Loan.

Surety Bonds

We issue surety bonds in the ordinary course of business to support our projects.  At June 30, 2020, we had $371.8 million of outstanding surety bonds.
