Item 8.01.  Other Events.

On April 2, 2013, Duke Energy Ohio, Inc. (the “Company” or “Duke Energy Ohio”) reached a settlement agreement (the “Settlement”) with all intervening parties in connection with its electric distribution rate case and gas distribution rate case filed on June 7, 2012 with the Public Utilities Commission of Ohio (“PUCO”).  Pursuant to the Settlement, the parties have agreed to a net annualized increase in electric distribution revenues of $49 million, or an average increase of 2.9% on a total bill basis for electric customers, and no increase in base rates for gas customers subject to the unresolved litigation over remediation costs associated with manufactured gas plants (“MGP”).  MGP remediation costs will be recovered by the Company through a rider with the amount of recovery subject to the results of litigation.  The Company has requested an annual revenue requirement of $22 million for its MGP remediation costs.  The Settlement is based upon an ROE of 9.84% and a 53.3% equity component of the capital structure.  Duke Energy Ohio has also agreed to donate $0.7 million annually for its low income weatherization and fuel fund.

The Settlement is subject to the review and approval of the PUCO.

An overview providing detail on the Settlement is attached to this Form 8-K as Exhibit 99.1.
