“Cash Equivalents” shall mean short-term, highly liquid investments that are readily convertible to known amounts of cash and which (i) are subject to an insignificant risk of changes in value, and (ii) have a short maturity of three months or less from the date of acquisition.

“EBITDAR” shall mean operating income excluding non-recurring items, earnings before interest, taxes, depreciation, amortization and Lease Expense in respect of aircraft and engines only.
