Accounting Changes and Error Corrections

Welcome to Accounting Changes and Error Corrections!

In the world of accounting, consistency is king. Investors want to compare this year’s numbers to last year’s numbers to see how a company is growing. But what happens when a company changes how it counts its inventory, or realizes they made a massive math error three years ago? That is what this chapter is all about! We are going to learn how to fix the past and update the future so that financial statements remain reliable and transparent. Don't worry if this seems a bit "heavy" at first—we will break it down piece by piece.

The Three Main Types of Changes

To master this topic for the FAR exam, you need to be a "categorization expert." There are three specific types of changes, and each has its own rule for how we report it. Think of it like this:
1. Change in Accounting Estimate (The "Moving Forward" approach)
2. Change in Accounting Principle (The "Time Machine" approach)
3. Change in Reporting Entity (The "Re-do" approach)

1. Change in Accounting Estimate (Prospective Application)

An estimate is an educated guess. Since we aren't psychic, these guesses often change as we get new information.
How to handle it: We use the Prospective approach. This means we do not go back and change old numbers. We just fix things for the current year and future years.
Common Examples:
- Changing the useful life or salvage value of an asset.
- Changing the percentage used for Bad Debt Expense.
- Settling a lawsuit for a different amount than originally guessed.

Example Analogy: Imagine you are driving and think you have enough gas to go 100 miles (your estimate). After driving 20 miles, you realize you only have enough for 50 more miles. You don't try to "fix" the miles you already drove; you just adjust your plan for the miles left in the tank!

A revision caused by new information is a change in estimate, applied prospectively to the current and future periods affected. A change in depreciation method is a change in estimate effected by a change in principle and is also prospective, with the required justification and disclosures. Correcting a calculation mistake or misuse of information available at the time is an error, not a new estimate.

Quick Review: Estimates

- Timing: Current and future periods only.
- Disclosures: Required if the change is material.
- Mistake to avoid: Never adjust Retained Earnings for a change in estimate!

2. Change in Accounting Principle (Retrospective Application)

A voluntary change between acceptable accounting principles generally requires preferability and retrospective application, unless impracticable. Follow specific transition provisions when a new standard supplies them. Adjust affected comparative periods and the opening balances of the earliest period presented as appropriate. ASC 606’s point-in-time versus over-time recognition follows its criteria; completed-contract versus percentage-of-completion is not a free current-GAAP policy choice.

Math Example: If switching from LIFO to FIFO makes your prior years' income \( \$10,000 \) higher, and your tax rate is \( 21\% \), you would increase your beginning Retained Earnings by:
\( \$10,000 \times (1 - 0.21) = \$7,900 \)

Key Takeaway: Principles

A voluntary change between acceptable accounting principles generally requires preferability and retrospective application, unless impracticable. Follow specific transition provisions when a new standard supplies them. Adjust affected comparative periods and the opening balances of the earliest period presented as appropriate. ASC 606’s point-in-time versus over-time recognition follows its criteria; completed-contract versus percentage-of-completion is not a free current-GAAP policy choice.

3. Change in Reporting Entity (Retrospective Application)

This occurs when the "group" of companies being reported on changes.
Common Examples:
- Presenting consolidated statements instead of individual statements.
- Changing the specific companies included in a consolidated group.

How to handle it: Just like a change in principle, this is handled Retrospective. You restate all prior periods presented to show the financial information for the new reporting entity as if it always existed that way.

Error Corrections (Prior Period Adjustments)

Material prior-period errors require restatement of the affected prior statements. Correct affected asset and liability balances and, when relevant, opening retained earnings or another equity account of the earliest period presented, considering tax effects. A classification-only error may not affect retained earnings. Moving from valid cash- or tax-basis special-purpose statements to GAAP is not automatically an error; it is an error if the earlier statements purported to follow GAAP but did not.

Common Mistake to Avoid: Don't confuse a "change in estimate" with an "error correction." If you change your mind about how long a truck will last because of new data, that's an estimate (Prospective). If you forgot to record depreciation on the truck entirely last year, that's an error (Retrospective).

You are doing great! This chapter is one of the "building blocks" of financial reporting. Once you master the difference between Prospective and Retrospective, you've won half the battle!
