Comprehensive and Detailed Step-by-Step Explanation with all IIA Reference: =

Understanding the Impact of an Understated Ending Inventory:

Ending inventory is a key component of the cost of goods sold (COGS) calculation:

COGS=BeginningInventory+Purchases−EndingInventoryCOGS = Beginning Inventory + Purchases -

Ending InventoryCOGS=BeginningInventory+Purchases−EndingInventory

If the ending inventory is understated, it means the reported inventory is lower than its actual value.

This results in an overstated COGS because a smaller amount is subtracted in the formula above.

An overstated COGS leads to an understated net income in the current year.

Effect on the Following Year’s Income Statement:

The beginning inventory for the next year is based on the ending inventory of the previous year.

Since the prior year's ending inventory was understated, the new year's beginning inventory is also

understated.

A lower beginning inventory leads to a lower COGS in the new year.

Since COGS is lower, net income in the following year will be overstated.

IIA’s Perspective on Financial Reporting Errors:

The IIA’s International Standards for the Professional Practice of Internal Auditing (IPPF) emphasize

the importance of accurate financial reporting.

IIA Standard 1220 – Due Professional Care requires internal auditors to consider the probability of

errors, fraud, or misstatements in financial reporting.

COSO’s Internal Control – Integrated Framework highlights that inventory valuation errors can

impact financial integrity and decision-making.

GAAP & IFRS Accounting Standards also require proper inventory reporting to ensure accurate

financial statements.
