A variety of issues has arisen in these cases, including the auditor’s obligation with respect to alleged internal controls at an audit client, whether the knowledge and actions of the client’s officers and directors and shareholders should be attributed to the client, whether the deepening insolvency theory is an appropriate theory or measure of damages, accounting for subprime loans and securitizations as well as loss reserves including troubled debt restructurings, and whether the actions of the accountant had any causal relationship to the damages sought in the case.

In addition, he has provided representation to accounting firms in numerous federal securities and derivative actions brought by stockholders in diverse federal and state courts as well as other claims brought by third parties.

A variety of issues has arisen in these cases including the propriety of the use of the fraud on the market theory, whether the plaintiffs had ever pleaded a claim for fraud under the applicable pleading standards, and whether loss reserves and similar balance sheet items are matters of fact or opinion.

Among other such work, he has represented clients in investigations conducted by the SEC, the PCAOB, the FDIC and the Comptroller of the Currency. He has also represented a number of firms before various state boards of accountancy.
