Comprehensive Income (Loss), Net of Tax, Attributable to Parent [Abstract]
Total comprehensive income			$ 151.8

[1] Trade receivables, net for the Non-Guarantors includes $226.9 at December 31, 2013 of U.S. trade receivables sold from the Guarantors to Energizer Receivables Funding Corp ("ERF"), a 100% owned, special purpose subsidiary, which is a non-guarantor of the Notes. These receivables are used by ERF to securitize the borrowings under the Company's receivable securitization facility. The trade receivables are short-term in nature (on average less than 90 days). As payment of the receivable obligation is received from the customer, ERF remits the cash to the Guarantors in payment for the purchase of the receivables. Cost and expenses paid by ERF related to the receivable securitization facility are re-billed to the Guarantors by way of intercompany services fees.

[2] Trade receivables, net for the Non-Guarantors includes $221.4 at September 30, 2013 of U.S. trade receivables sold from the Guarantors to Energizer Receivables Funding Corp ("ERF"), a 100% owned, special purpose subsidiary, which is a non-guarantor of the Notes. These receivables are used by ERF to securitize the borrowings under the Company's receivable securitization facility. The trade receivables are short-term in nature (on average less than 90 days). As payment of the receivable obligation is received from the customer, ERF remits the cash to the Guarantors in payment for the purchase of the receivables. Cost and expenses paid by ERF related to the receivable securitization facility are re-billed to the Guarantors by way of intercompany services fees.

[3] Intercompany activity includes notes that bear interest due from the Guarantors to the Parent Company. Interest rates on these notes approximate the interest rates paid by the Parent on third party debt. Additionally, other intercompany activities include product purchases between Guarantors and Non-Guarantors, charges for services provided by the parent and various subsidiaries to other affiliates within the consolidated entity and other intercompany activities in the normal course of business.
