Final answer:
The correct answer is 'An unusual increase in current ratio,' as it is not a direct indicator of liability fraud, unlike the other options, which do suggest manipulation of financial records.
Step-by-step explanation:
The subject of liability fraud falls under Business, specifically in the context of financial accounting and auditing. When examining the options provided, they all detail potential red flags for liability fraud except for one: 'An unusual increase in current ratio'. An increase in the current ratio generally indicates a company has more current assets relative to its current liabilities, which is not directly indicative of fraudulent activity. In contrast, the other options directly suggest manipulation of financial records to misstate the company's financial health and obligations.
A sudden decrease in accounts payable/inventory ratio can signal that payables are being delayed or inventory is overstated. Inappropriately capitalizing costs that should be expensed can misrepresent the company's financial position, as this defers expenses to future periods, thus inflating current earnings. Recording payments made in later periods as being paid in earlier periods also misstates the financial condition by understating liabilities.
