Item 8.01 Other Events.

On October 15, 2010, OmniSource Indianapolis LLC (“OmniSource”), an indirect subsidiary of Steel Dynamics, Inc., filed a lawsuit against Carl Brizzi, as the Prosecutor of Marion County, Indiana, seeking the return of approximately $277,000 in cash seized from OmniSource on February 23, 2009, during a police raid on OmniSource’s Indianapolis scrap yard facilities. In its lawsuit against Mr. Brizzi, OmniSource claims that the police raid and seizure, purportedly involving certain isolated purchases by OmniSource personnel of a small amount of allegedly stolen scrap metal (and denied by OmniSource), actually constituted part of a meritless plan by Mr. Brizzi, and his contingent fee private lawyer to extract money from OmniSource under a threat of potential civil forfeiture of millions of dollars’ worth of the company’s property.

Consistent with OmniSource’s description of Brizzi’s motivation, on December 30, 2010, in the last hours of Mr. Brizzi’s power as Marion County Prosecutor, he filed a counterclaim to OmniSource’s complaint, seeking the civil forfeiture of all of OmniSource’s Indianapolis scrap facilities and certain other properties and facilities not even owned by the company, as well as the appointment of a receiver and other remedies. OmniSource believes that Brizzi’s Counterclaim is preposterous and without any factual or legal merit.

OmniSource is confident that the newly elected Prosecutor and his staff will want to review and re-examine Mr. Brizzi’s imprudent actions, including his decision to file this baseless Counterclaim against OmniSource in the waning hours of his administration’s existence.

In the meantime, OmniSource has moved to dismiss the Counterclaim.

OmniSource trusts that the new Marion County Prosecutor, Terry Curry, will recognize the lack of merit in any of the allegations made against OmniSource and will promptly dismiss all proceedings against the company.  If not, OmniSource will utilize every means to aggressively defend itself, its employees, its property and the fine commercial reputation it has built over more than a half century of service.
