Final answer:
Inventory errors do impact a company's net income by affecting the income statement and balance sheet, and they can also affect Retained Earnings if the errors pertain to a prior period. These errors are not irreversible and do not directly affect pre-tax cash flow. Corrective adjustments may involve both balance sheet and income statement accounts.
Step-by-step explanation:
Regarding inventory errors and their impact on financial statements, the correct statement is that inventory errors do have an effect on a company's net income, because they affect both the income statement and the balance sheet. If there is an error in the beginning inventory, it will understate or overstate the cost of goods sold (COGS), which will, in turn, affect the net income for that period. Moreover, if the error is not corrected in the same period, it will carry over and affect net income in the subsequent period as well. This happens because the ending inventory for one period becomes the beginning inventory for the next period. As for the Retained Earnings, an error in the inventory will indeed affect this account but only if the error pertains to a prior period and the financial statements for that period have already been issued. In such a case, a prior period adjustment to Retained Earnings is required to correct the error. Inventory errors do not directly affect a company's pre-tax cash flow, as cash flow is concerned with actual transactions rather than accounting valuations. Correcting inventory errors often involves making adjustments to both balance sheet and income statement accounts and is not irreversible; they can be corrected once identified.
