I am currently studying for AUD w/ Roger, and like you, take it 8/28. It has not been a pleasant experience. I am looking forward to getting through the rest of the lectures so I can start my NINJA MCQ review.
This question is a bitch. I had the same issue as you did. I assume the reason Roger uses it is because it is a released question, no longer used. I assume the reason it is no longer used is because it is a shit question.
Let's break it down. A/R turnover is net credit sales over average A/R. When credit sales are not specified and beginning and ending A/R is not provided, it is simply sales divided by A/R.
A decrease in A/R Turnover would mean an DECREASE in credit sales, or an INCREASE in A/R balance.
A: If fictitious credit sales were recorded, the sales would increase and A/R would increase by the same amount. This would increase A/R turnover.
B: If an employee stole inventory, it would affect neither sales nor A/R.
C: There isn't enough information to determine how tightening a credit-granting policy would affect BOTH accounts, so it's impossible to say if this would increase or decrease the credit granting policy.
D: Since we know the other 3 are wrong, this has to be the answer. Assuming everything else remains constant, the collection will always be one behind. Since the lapping started in Y1, the beginning A/R balance is correct, while the ending A/R balance is fraudulently overstated. In Y2, the beginning balance is fraudulently overstated, and the ending balance is still fraudulently overstated. Thus, A/R will increase in Y2 relative to everything else, and the A/R Turnover ratio will decrease.
