Piv Background: You are testing the accuracy and valuation management assertion of the allowance for bad debt account for your client, Oakley Turf, using its A/R subsidiary ledger in cells A18:A67. Instructions: (1) Use the SUMIF function in cells B15:B17 to compute the sum for each balance status as efficiently as possible using Excel formulas; (2) Foot the A/R subsidiary ledger provided to the client's recorded A/R balance from the trial balance to make sure the information they provided you was complete. Also foot the A/R total in B18 and agree the amount to the client's recorded A/R balance (ensure it says "Yes" in cell D18); (3) Calculate your expectation for the Allowance for Bad Debt account in cell C21 and compare it to the client's recorded amount by calculating a difference between recorded and expected amounts in cell C22, and describe in cell B25 what (if any) steps you will take next as the auditor. All work on this assignment must be your team's own. Direct questions to your professor, not classmates.
