Item 8.01 Other Events.

Senior Notes Offering

On January 18, 2012, Stifel Financial Corp. (the “Company”, “Stifel” or “we”) announced that it intends to commence an underwritten public offering of its Senior Notes due January 2022 (“Senior Notes”). The underwriters will be granted a 30-day option to purchase additional Senior Notes from the Company to cover over-allotments, if any. The offering will be made pursuant to an effective shelf registration statement previously filed with the Securities and Exchange Commission.

Wisconsin Lawsuit

On January 16, 2012, we and our primary broker-dealer subsidiary, Stifel Nicolaus, were named as defendants in a suit filed in Wisconsin state court with respect to Stifel Nicolaus’ role as initial purchaser in a $50 million bond offering under Rule 144A in January 2008. The bonds were issued by the Lake of the Torches Economic Development Corporation (“EDC”) in connection with certain new financing for the construction of a proposed new casino, as well as refinancing of indebtedness involving Lac Du Flambeau Band of Lake Superior Chippewa Indians (the “Tribe”), who are also defendants in the action, together with Godfrey & Kahn, S.C. (“G&K”) who served as both issuer’s counsel and bond counsel in the transaction. In an earlier action in federal court in Wisconsin related to the transaction, EDC was successful in its assertion that the bond indenture was void as an unapproved “management contract” under National Indian Gaming Commission regulations, and that accordingly the waiver of sovereign immunity contained in the indenture was void.

Saybrook Tax Exempt Investors LLC, a qualified institutional buyer and the sole bondholder through its special purpose vehicle LDF Acquisition LLC (collectively, “Saybrook”), and Wells Fargo Bank, NA (“Wells Fargo”), indenture trustee for the bonds (collectively “plaintiffs”) brought the Wisconsin state court suit against EDC, Stifel and G&K, based on alleged misrepresentations about the enforceability of the indenture and the bonds and the waiver of sovereign immunity. The plaintiffs allege that G&K represented in various legal opinions issued in the transaction, as well as in other documents associated with the transaction, that (i) the bonds and indenture were legally enforceable obligations of EDC and (ii) EDC’s waivers of sovereign immunity were valid. The claims asserted against Stifel are for breaches of implied warranties of validity and title, securities fraud and statutory misrepresentation under Wisconsin state law, intentional and negligent misrepresentations relating to those matters. In addition to claims against EDC, the plaintiffs are seeking a judgment against Stifel and G&K to the extent EDC does not fully perform its obligations to Saybrook pursuant to the bonds and damages, costs and attorneys’ fees. Stifel believes it has meritorious defenses to the matter. Stifel intends to defend the claims vigorously, although there can be no assurance that such defense will be successful.
