​ Revolving Credit Facility ​ On April 18, 2018, we amended our senior credit facility (the “Facility”) provided by a syndicate of banks, increasing our borrowing capacity from $325.0 million to $400.0 million, with a $100 million accordion option. The Facility, which is available for borrowings and letters of credit, expires in April 2023 and is secured by a first lien on substantially all of our personal property except for assets related to projects subject to surety bonds and assets held by certain unrestricted subsidiaries and a second lien on our assets related to projects subject to surety bonds. As of March 31, 2019, we had $51.0 million of outstanding borrowings, $33.6 million in letters of credit outstanding and $315.4 million of credit available. ​ There are two interest rate options for borrowings under the Facility, the Base Rate Loan Option and the Eurodollar Rate Loan Option. These rates are floating rates determined by the broad financial markets, meaning they can and do move up and down from time to time. Additional margins are then added to these two rates. ​ The following is a summary of the additional margins: ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Consolidated Total Indebtedness to |
​ | ​ | Credit Facility Adjusted EBITDA |
​ |  | Less than 1.00 |  | 1.00 to 1.75 |  | 1.75 to 2.50 |  | 2.50 or greater |
Additional Per Annum Interest Margin Added Under: | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
Base Rate Loan Option | ​ | 0.25 | % | 0.50 | % | 0.75 | % | 1.00 | %
Eurodollar Rate Loan Option | ​ | 1.25 | % | 1.50 | % | 1.75 | % | 2.00 | %
​ The weighted average interest rate applicable to the borrowings under the Facility was approximately 3.7% as of March 31, 2019. ​ Certain of our vendors require letters of credit to ensure reimbursement for amounts they are disbursing on our behalf, such as to beneficiaries under our self-funded insurance programs. We have also occasionally used letters of credit to guarantee performance under our contracts and to ensure payment to our subcontractors and vendors under those contracts. Our lenders issue such letters of credit through the Facility. We have never had a claim made against a letter of credit that resulted in payments by a lender or by us and believe such a claim is unlikely in the foreseeable future. The letter of credit fees range from 1.25% to 2.00% per annum, based on the ratio of Consolidated Total Indebtedness to Credit Facility Adjusted EBITDA, as defined in the credit agreement. ​ Commitment fees are payable on the portion of the revolving loan capacity not in use for borrowings or letters of credit at any given time. These fees range from 0.20% to 0.35% per annum, based on the ratio of Consolidated Total Indebtedness to Credit Facility Adjusted EBITDA, as defined in the credit agreement. ​ The Facility contains financial covenants defining various financial measures and the levels of these measures with which we must comply. Covenant compliance is assessed as of each quarter end. ​ The Facility’s principal financial covenants include: ​ Total Leverage Ratio—The Facility requires that the ratio of our Consolidated Total Indebtedness to our Credit Facility Adjusted EBITDA not exceed 3.00 to 1.00 as of the end of each fiscal quarter. The total leverage ratio as of March 31, 2019 was 0.4. ​ Fixed Charge Coverage Ratio—The Facility requires that the ratio of (a) Credit Facility Adjusted EBITDA, less non-financed capital expenditures, provision for income taxes, dividends and amounts used to repurchase stock to (b) the sum of interest expense and scheduled principal payments of indebtedness be at least 2.00 to 1.00; provided that the calculation of the fixed charge coverage ratio excludes stock repurchases and the payment of dividends at any time that the Company’s Net Leverage Ratio, as defined in the credit agreement, does not exceed 1.75 to 1.00. The Facility also allows the fixed charge coverage ratio not to be reduced for stock repurchases made after the effective date of the Facility in an aggregate amount not to exceed $30 million, if at the time of and after giving effect to such repurchase the Company’s Net Leverage Ratio was less than or equal to 1.75 to 1.00. Credit Facility Adjusted EBITDA, capital expenditures, provision for income taxes, dividends, stock repurchase payments, interest expense, and scheduled principal payments are defined under the Facility for purposes of this covenant to be amounts for the four quarters ending as of any given quarterly covenant compliance measurement date. The fixed charge coverage ratio as of March 31, 2019 was 22.6. ​ Other Restrictions—The Facility permits acquisitions of up to $40.0 million per transaction, provided that the aggregate purchase price of all such acquisitions in the same fiscal year does not exceed $80.0 million. However, these limitations only apply when the Company’s Total Leverage Ratio is greater than 2.00 to 1.00. ​ While the Facility’s financial covenants do not specifically govern capacity under the Facility, if our debt level under the Facility at a quarter-end covenant compliance measurement date were to cause us to violate the Facility’s leverage ratio covenant, our borrowing capacity under the Facility and the favorable terms that we currently have could be negatively impacted by the lenders. ​ We were in compliance with all of our financial covenants as of March 31, 2019. ​ Notes to Former Owners ​ As part of the consideration used to acquire six companies, we have outstanding notes to the former owners. These notes had an outstanding balance of $26.2 million as of March 31, 2019. In conjunction with an acquisition in the first quarter of 2019, we issued a promissory note to former owners with an outstanding balance of $0.4 million as of March 31, 2019 that bears interest, payable quarterly, at a weighted average interest rate of 3.0%. The principal is due in January 2021. In conjunction with an acquisition in the third quarter of 2018, we issued a promissory note to former owners with an outstanding balance of $6.5 million as of March 31, 2019 that bears interest, payable quarterly, at a weighted average interest rate of 3.5%. The principal is due in three equal installments in July 2019, 2020 and 2021. In conjunction with a separate acquisition in the third quarter of 2018, we issued a promissory note to former owners with an outstanding balance of $3.5 million as of March 31, 2019 that bears interest, payable quarterly, at a weighted average interest rate of 2.9%. The principal is due in September 2020. In conjunction with a small acquisition in the second quarter of 2018, we issued a subordinated note to former owners with an outstanding balance of $1.0 million as of March 31, 2019 that bears interest, payable quarterly, at a weighted average interest rate of 3.5%. The principal is due in equal installments in May 2020 and 2021. In conjunction with a small acquisition in the first quarter of 2018, we issued a subordinated note to former owners with an outstanding balance of $0.5 million as of March 31, 2019 that bears interest, payable quarterly, at a weighted average interest rate of 2.5%. The principal is due in January 2020. In conjunction with the BCH acquisition in the second quarter of 2017, we issued a promissory note to former owners with an outstanding balance of $14.3 million as of March 31, 2019 that bears interest, payable quarterly, at a weighted average interest rate of 3.0%. The principal is due in equal installments in April 2020 and 2021. ​ Other Debt ​ As part of the Shoffner acquisition, we acquired debt with an outstanding balance at the acquisition date of $0.4 million with principal and interest due the last day of every month; ending on the December 30, 2019 maturity date. The interest rate is the one month LIBOR rate plus 2.25%. As of March 31, 2019, $0.1 million of the note was outstanding, all of which was considered current.
