(1)      Earnings represent income from continuing operations before provision
         for income taxes and cumulative effect of accounting change.

(2)      Includes amortization of debt expense and capitalized interest.

(3)      Includes provision for merger and restructuring expenses of $120,000
         pre-tax ($80,000 or $.36 per share after tax) related to the merger of
         The Price Company and Costco Wholesale Corporation in October 1993. If
         such provision for merger and restructuring expenses were excluded,
         income from continuing operations before provision for income taxes for
         fiscal 1994 would have been $323,555.

(4)      If the $120,000 pre-tax provision for merger and restructuring expenses
         were excluded, the ratio of earnings to fixed charges for fiscal 1994
         would have been 4.7.

(5)      Includes the effect of adopting SFAS No. 121, a $65,000 pre-tax charge
         for asset impairment. If such provision were excluded, income from
         continuing operations before provision for income taxes for fiscal 1997
         would have been $585,329.

(6)      If the $65,000 pre-tax provision for asset impairment were excluded,
         the ratio of earnings to fixed charges would have been 6.2.
