Effective October 24, 2018, we entered into a Second Amended and Restated Credit Agreement (the “2018 Credit Agreement”). The 2018 Credit Agreement has a maturity date of October 24, 2023 and provides for a $450 million revolving credit facility (“2018 Credit Facility”). Proceeds from the 2018 Credit Facility were used to refinance certain of our outstanding debt and provide us with additional funds for our operations, growth initiatives, acquisitions, and other general corporate purposes in the ordinary course of business. The 2018 Credit Facility may be increased up to an additional $250 million under certain circumstances. It has a $20 million sublimit for letters of credit. Borrowings and letters of credit can be denominated in U.S. dollars, Euros, Canadian dollars, or British pounds. Our lenders under the 2018 Credit Facility have a first perfected security interest in all of our personal property including GES, GES Event Intelligence Services, Inc., CATC Alaska Tourism Corporation (“CATC”), ON Event Services, LLC (“ON Services”), and 65% of the capital stock of our top-tier foreign subsidiaries (other than Esja). Financial covenants include an interest coverage ratio of not less than 3.00 to 1.00 and a leverage ratio of not greater than 3.50 to 1.00, with a step-up of 4.00 to 1.00 for four quarters for a material acquisition of $50 million or more. Dividends are permitted up to $15 million in any calendar year. In addition, we can declare and pay dividends or repurchase our common stock up to $20 million per calendar year. Dividends and repurchases above those thresholds are permitted as long as our pro forma leverage ratio is less than or equal to 2.75 to 1.00. Unsecured debt is allowed provided we are in compliance with the leverage ratio. In addition, the unsecured debt must mature after the expiration of the 2018 Credit Facility, cannot have scheduled principal payments while the 2018 Credit Facility is in place, and any covenants for unsecured debt cannot be more restrictive than the 2018 Credit Facility. Significant other covenants include limitations on investments, additional indebtedness, sales and dispositions of assets, and liens on property. As of March 31, 2019, the interest coverage ratio was 13.20 to 1.00, the leverage ratio was 1.92 to 1.00, and we were in compliance with all covenants under the 2018 Credit Agreement.

Borrowings under the 2018 Credit Facility (of which GES, GES Event Intelligence Services, Inc., CATC, and ON Services are guarantors) are indexed to the prime rate or the London Interbank Offered Rate (“LIBOR”), plus appropriate spreads tied to our leverage ratio. We understand that LIBOR will be phased out in 2021. The vast majority of our borrowings under the 2018 Credit Facility are indexed to the LIBOR. We do not expect the successor rate to have a material impact on our interest expense. Commitment fees and letters of credit fees are also tied to our leverage ratio. The fees on the unused portion of the 2018 Credit Facility were 0.3% annually as of March 31, 2019.

As of March 31, 2019, capacity remaining under the 2018 Credit Facility was $206.5 million, reflecting borrowings of $239.9 million and $3.6 million in outstanding letters of credit.

Effective February 15, 2019, FlyOver Iceland ehf., a wholly-owned subsidiary of Esja, entered into a credit agreement with a €5.0 million (approximately $5.6 million) credit facility (the “FlyOver Iceland Credit Facility”) with a maturity date of March 1, 2022. The loan proceeds will be used to complete the development of the FlyOver Iceland attraction.

As of March 31, 2019, capacity remaining under the FlyOver Iceland Credit Facility was approximately $3.3 million.

The estimated fair value of total debt was $239.1 million as of March 31, 2019 and $228.6 million as of December 31, 2018. The fair value of debt was estimated by discounting the future cash flows using rates currently available for debt of similar terms and maturity, which is a Level 2 measurement. Refer to Note 13 – Fair Value Measurements.

Cash paid for interest on debt was $2.7 million for the three months ended March 31, 2019 and $1.9 million for the three months ended March 31, 2018.
