Osborne Computer Corporation was founded in 1980 by entrepreneur Adam Osborne and began manufacturing the Osborne I portable personal computer for the mass market, with shipments starting in 1981. By fall 1982, sales of the company's sole product had reached $10 million per month, making the company one of the fastest growing enterprises in the history of American business. In 1981 and again in 1982, the company retained Arthur Young & Company to audit its financial statements and issue audit reports. Arthur Young issued unqualified audit opinions on the company's 1981 and 1982 financial statements. The 1982 opinion was issued on February 11, 1983, appeared on Arthur Young's letterhead addressed to the company, and 100 copies of the professionally printed opinion were personally delivered to the company. The 1982 financial statements reported a modest net operating profit of $69,000 on sales of more than $68 million. In late 1982 the company postponed a planned initial public offering and instead issued warrants to investors in exchange for bridge financing loans or letters of credit. Plaintiffs, a group that included individuals as well as pension and venture capital funds, invested in the company in early 1983; one plaintiff, Robert Bily, purchased 37,500 shares of stock from Adam Osborne for $1.5 million. With one exception, plaintiffs testified that they made their investments in reliance on Arthur Young's unqualified 1982 audit opinion. After the warrant transaction closed on April 8, 1983, sales declined sharply because of manufacturing problems with the company's new Executive model computer, the public offering never occurred, and the company filed for bankruptcy on September 13, 1983, causing plaintiffs to lose their investments. Plaintiffs brought separate lawsuits against Arthur Young in Santa Clara County Superior Court that were consolidated for trial. Plaintiffs' expert witness identified more than 40 deficiencies in the 1982 audit amounting to gross professional negligence, including an understatement of liabilities by approximately $3 million that turned the reported $69,000 profit into a loss of more than $3 million, and testified that Arthur Young had discovered but failed to disclose material weaknesses in the company's internal accounting controls. After a 13-week trial the jury returned a verdict for plaintiffs on the professional negligence claim and awarded approximately $4.3 million in compensatory damages, but found for Arthur Young on the fraud and negligent misrepresentation claims. The trial court granted Arthur Young's motion for judgment notwithstanding the verdict on the negligence claim. The Court of Appeal reversed the judgment in favor of Arthur Young. The Supreme Court of California granted review.
