Here is the entire question:
The following information pertains to Smoke, Inc.'s investment in marketable equity securities:
• On December 31, 20X1, Smoke reclassified a security with a $70,000 cost and a $50,000 market value from trading to available for sale.
• A marketable equity security available for sale costing $75,000, written down to $30,000 in 20X0, had a $60,000 market value on December 31, 20X1.
What is the net effect of the above items on Smoke's valuation allowance for marketable equity securities available for sale as of December 31, 20X1?
a. No effect
b. 10 decrease
c. 20 increase
d. 30 decrease
Answer D. The reclassification from trading to available for sale would be done at the fair market value of $50,000 and the valuation allowance would not be affected. The security that had been written down to $30,000 in 20X0 would be written back up to $60,000 in 20X1, decreasing the valuation allowance.
