Exhibit 11 Richardson Electronics, Ltd. and Subsidiaries Computation of Net Income per Share Net income (loss) per share for 1994, 1993 and 1992 was computed by dividing net income (loss) by the weighted average number of common and common share equivalents outstanding. The treasury stock method was applied to those stock options that would have a dilutive effect on net income per share. The average market price of the Company's stock was used in determining primary income per share, while the year-end market price (if greater than the average market price) was used in determining fully diluted net income per share. The Company's 7 1/4% Convertible Debentures have not been included in the calculation of income per share because their effect would be anti-dilutive. Fully diluted income per share has not been presented on the face of the income statement because it does not differ significantly from primary income per share for each year.
