Revolving Credit Facility On June 25, 2013, we amended our senior credit facility (the "Facility") provided by a syndicate of banks increasing our borrowing capacity from $125.0 million to $175.0 million. The Facility, which is available for borrowings and letters of credit, expires in July 2018 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 June 30, 2014, we had $52.0 million of outstanding borrowings, $50.6 million in letters of credit outstanding and $72.4 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 0.75 |  | 0.75 to 1.50 |  | 1.50 to 2.25 |  | 2.25 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 3.50% as of June 30, 2014. We have 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 for a fee. 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 claims are 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: Leverage Ratio—The Facility requires that the ratio of our Consolidated Total Indebtedness to our Credit Facility Adjusted EBITDA not exceed 3.00 through December 31, 2014, 2.75 through December 31, 2015 and 2.50 through maturity. The leverage ratio as of June 30, 2014 was 0.77. Fixed Charge Coverage Ratio—The Facility requires that the ratio of Credit Facility Adjusted EBITDA, less non-financed capital expenditures, tax provision, dividends and amounts used to repurchase stock to the sum of interest expense and scheduled principal payments of indebtedness be at least 2.00; 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 does not exceed 1.50. The Facility also allows the fixed charge coverage ratio not to be reduced for stock repurchases through June 30, 2015 in an aggregate amount not to exceed $25 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 1.50. Capital expenditures, tax provision, dividends and stock repurchase 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 June 30, 2014 was 24.84. Other Restrictions—The Facility permits acquisitions of up to $20.0 million per transaction, provided that the aggregate purchase price of such an acquisition and of acquisitions in the same fiscal year does not exceed $50.0 million. However, these limitations only apply when the Company's Net Leverage Ratio is equal to or greater than 2.00. 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 are in compliance with all of our financial covenants as of June 30, 2014. Notes to Former Owners We issued subordinated notes to the former owners of acquired companies as part of the consideration used to acquire these companies. These notes bear interest, payable annually, at a weighted average interest rate of 3.3%. In June 2014, we paid the outstanding balance of $2.0 million. Other Debt Our majority owned subsidiary, EAS, had a revolving $2.5 million credit line that was available for temporary working capital needs and expired June 30, 2014. This line of credit was not renewed until July 29, 2014 and expires July 31, 2015. The terms and conditions under the renewed agreement are substantially consistent with the previously existing agreement.
