A description of the Credit Facility was previously disclosed in the Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on June 2, 2015, as discussed under Item 2.03 below. No early termination penalties were incurred by the Company in connection with the termination of the Prior Credit Facility.

A description of the Bridge Facility was previously disclosed in the Company’s Current Report on Form 8-K filed with the SEC on April 30, 2015. The Company repaid $1.0 billion of loans outstanding under the Bridge Facility, together with accrued interest thereon, from cash proceeds of $1.0 billion received from New Energizer (as defined below) in connection with Spin-Off and from cash on hand. No early termination penalties were incurred by the Company in connection with the termination of the Bridge Facility.

Certain of the parties to the Prior Credit Facility, the Credit Facility and the Bridge Facility or their affiliates have or may have had various relationships with us and our subsidiaries involving the provision of a variety of financial services, including investment banking, underwriting, commercial banking and letters of credit, for which the parties or their affiliates receive customary fees and, in some cases, out-of-pocket expenses.
