Broad-Based Stock Option Plan Transparency Act of 2003

Broad-Based Stock Option Plan Transparency Act of 2003 - Directs the Securities and Exchange Commission (SEC) to require that certain mandatory periodic reports include detailed information regarding stock option plans, stock purchase
plans, and other arrangements involving an employee acquisition of an equity interest in the publicly traded company, particularly with respect to the dilutive effect of such plans.

Requires such reports to include: (1) a discussion, written in "plain English" of the dilutive effect of stock option plans, including tables or graphic illustrations; (2) expanded disclosure of the dilutive effect of employee stock options upon the earnings per share number of the company; (3) prominent placement and increased comparability of all stock options related information; and (4) a summary of the stock options granted to the five most highly compensated executive officers of the company, including any outstanding stock options of those officers.

Directs the SEC to study and report to Congress on the effectiveness of the enhanced disclosures in increasing transparency to investors.

Prohibits the SEC from recognizing as generally accepted accounting principles for purposes of enforcing the securities laws any accounting standards related to the treatment of stock options that it did not recognize for that purpose before April 1, 2003.

Instructs the Secretary of Commerce to report to Congress on a study and analysis of broad-based employee stock option plans, particularly in the high technology and any other high growth industries.
