Final answer:
The effect of writing off uncollectible accounts on net income depends on the accounting method used. For Lundstrom Company, using the direct write-off method, there is no effect on net income in 20X1, but net income is decreased in 20X2.
Step-by-step explanation:
The effect of writing off uncollectible accounts on net income depends on the accounting method used. In this case, Lundstrom Company used the direct write-off method.
For 20X1, the write-off of uncollectible accounts would have no effect on net income because the direct write-off method recognizes bad debts only when they are confirmed as uncollectible.
For 20X2, the write-off of the material amount of uncollectible accounts would decrease net income. This is because it represents an expense incurred in the current year, reducing the company's profitability.
