These covenants are subject to a number of limitations and exceptions. Additionally, if a change of control triggering event occurs, as defined in the indenture governing the 2031 Notes, we will be required to offer to purchase the 2031 Notes at 101% of the outstanding aggregate principal amount plus accrued interest up to the purchase date.
