SP Syntax LLC v. Ernst & Young LLP, et al.*

(Cal. Super. Ct.). Following a three-week trial in California Superior Court, won a unanimous jury verdict on behalf of Ernst & Young (E&Y), defeating claims that the accounting firm had made negligent representations in connection with financial statements issued by Syntax-Brillian, a manufacturer of flat-screen televisions that filed for bankruptcy in 2008. Silver Point, a hedge fund, sought $50 million that it was unable to recover from Syntax-Brillian's bankruptcy proceedings, alleging that a $130 million loan it had extended to Syntax-Brillian would not have occurred but for alleged misrepresentations in E&Y's audit of the company. The jury concluded that Ernst & Young had made no misrepresentations.

Frontier Insurance Group, Inc. v. Ernst & Young LLP*

(S.D.N.Y.). In a jury trial in the Southern District of New York, successfully defended Ernst & Young ("E&Y”) in an actuarial malpractice case. The case stemmed from the decision by the New York State Department of Insurance to place Frontier Insurance Company ("FIC”) in rehabilitation. FIC's parent claimed it relied on Ernst & Young's assessment of the company's reserve estimates in deciding to make capital contributions to its primary operating subsidiary, and wanted to recoup those investments from E&Y, seeking in excess of $200 million. The jury determined that E&Y and its actuaries had acted reasonably.

(N.Y. Sup. Ct.; S.D.N.Y.). Won favorable out-of-court settlement on behalf of the Canadian accounting firm of Ernst & Young LLP in a lawsuit brought by investors trying to recoup alleged losses resulting from junk bonds issued by Semi-Tech Corp. After Semi-Tech filed for bankruptcy, and the bonds became worthless, the investors brought suit against Semi-Tech's former officers and directors, as well as E&Y Canada, which had audited Semi-Tech's financial statements.
