For many companies, inventory is a significant dollar amount on the
company's financial statements. So it's crucial that recorded inventory
balances reflect actual values. When such accounts aren't properly stated, the
cost of goods sold and current ratios – numbers that often matter to decision
makers – may be skewed. If banks discover that your company's inventory
accounts are overstated, they may not extend credit. If, when necessary,
inventories aren't "written down" (their values lowered in the
accounting records), fraud may go undetected or the company's net profits may
appear unrealistically rosy.
Inventories decline in value for a variety of reasons. You might be in the
business of selling electronic equipment to retail customers. Over time,
yesterday's "latest and greatest" gadgets become today's ho-hum
commodities. Such goods still have value, but they can't be sold at last year's
prices. Your inventory is experiencing "obsolescence."
Inventory "shrinkage" is another term that's often used to
describe declining inventory values. Let's say you run a construction materials
company. Unbeknownst to you, a dishonest supervisor is skimming goods from your
shelves. A periodic inventory count that's compared to your company's general
ledger might show that inventory is declining faster than it's being sold. As a
result, you may decide to investigate and to reduce inventory values in your
accounting records.
Other examples of shrinkage might include a clothing store that loses
inventory due to shoplifting or a warehouse facility that's hit by a storm. In
both cases, inventories may need to be written down in the company books to
more accurately reflect actual values. Under another scenario, a shady supplier
might bill your company for goods that aren't actually shipped or received. If
invoices are recorded in your accounting records at full cost, your inventory
may end up being overstated.
For some companies, several sources feed into inventory values. A
manufacturing concern, for example, might add all the expenses needed to
prepare goods for sale – including factory overhead, shipping fees, and raw
material costs – into inventory accounts. When those supporting costs
fluctuate, inventory accounts are often affected.
To ensure that your inventory numbers remain accurate, it's a good idea to
conduct regular physical counts and routinely analyze the accounts for
shrinkage, obsolescence, and other evidence of diminishing value.
