(the “Issuer”), priced its offering of $700 million in aggregate principal amount of 7.125% senior unsecured notes due 2028 (the “Notes”).

The offering of the Notes is expected to close on July 1, 2020, subject to customary closing conditions.

The Notes will not be registered under the Securities Act, or any state securities laws, and may not be offered or sold in the United States absent registration, except pursuant to an exemption from the registration requirements of the Securities Act and applicable state securities laws.
