Instructions

(a)

Prepare a work sheet to show the adjusted net income figure for each of the six years after taking the inventory corrections into account.

(b)

Prepare a schedule that indicates both the original retained earnings balance reported at the end of each year and the corrected amount.

(c)

Consider the trends in the increase in income from 2012 to 2017 as originally reported and as revised after the corrections. Would you suspect that the income is being manipulated by adjusting the ending balance in the inventory account?
