Answer:
B. Add: decrease in accounts payable $1,000.
Explanation:
Operating Cash Flow (OCF) can be described as the cash that comes from the normal operating activities a company during a particular period.
The operating cash flow section starts with net income and other items that appear under it include change in current assets and current liabilities.
The following are 4 rules that employed to determine the nature of an adjustment to a current asset or current liability under the operating cash flow section of the cash flow statement:
Rule 1: When a current asset increases, you deduct.
Rule 2: But when a current asset reduces, you add.
Rule 3: When a current a liability increases, you add.
Rule 4: But when a current liability reduces, you deduct.
The 4 rules are now applied to this question as follows:
A. Deduct: increase in accounts receivable $3,000.
Account receivable is a current asset and there is an increase in it. Based on Rule 1, we deduct. Therefore, what is done is correct and will appear in the operating section of the cash flow.
B. Add: decrease in accounts payable $1,000.
Accounts payable is a current liability and there is a decrease in it. Based on Rule 4, we should deduct. Therefore, what is done is wrong and will not appear in the operating section of the cash flow.
C. Add: increase in taxes payable $2,400.
Taxes payable is a current liability and there is an increase in it. Based on Rule 3 above, we add. Therefore, what is done for this is correct and will appear in the operating section of the cash flow.
D. Add: decrease inventories $6,000.
Inventory is a current asset and there is a decrease in it. Based on Rule 2 above, we add. Therefore, what is done is correct and will appear in the operating section of the cash flow.
Conclusion
Based on the analysis above, only option B is wrong and will not appear in the the operating section of the cash flow. Therefore, the answer is B. Add: decrease in accounts payable $1,000.
