The Company also has certain negative financial covenants such as liens, advances, change in business, sales of assets, dividends and stock repurchases. These covenants are tested either monthly or quarterly and the Company was in full compliance with all financial covenant requirements at June 30, 2018.

The Company maintains a revolving credit facility to finance the acquisition of aircraft engines for lease as well as for general working capital purposes.

The interest rate is adjusted quarterly, based on the Company’s leverage ratio, as calculated under the terms of the revolving credit facility.
