ASC 255: Changing Prices — Complete Guide
ASC 255 is the FASB Accounting Standards Codification Topic focused on supplementary reporting concepts related to changing prices and inflation. This guide explains the Topic in plain English, shows the accounting decision process, gives a practical example, identifies related Topics, and connects the guidance to real-world financial reporting.
What Is ASC 255?
ASC 255, Changing Prices, sits within the Presentation Area of the FASB Accounting Standards Codification. In practical terms, it is used when an accountant needs authoritative U.S. GAAP research for supplementary reporting concepts related to changing prices and inflation.
The Topic number is a research address: the detailed requirements live in Subtopics, Sections, and paragraphs below the Topic level.
Accountant Compass treats the Topic page as an educational map, not as a replacement for the Codification. The purpose is to help a student or practitioner understand the accounting problem, identify the main decision points, and know where deeper authoritative research is required.
Because scope exceptions, private-company alternatives, transition rules, SEC requirements, and industry guidance can change the answer, transaction-specific conclusions should always be verified in current authoritative literature.
Scope and Key Decision Points
The first step is never to jump directly to a journal entry. Start by asking whether the transaction or reporting issue is within ASC 255, whether another Topic or industry Subtopic is more specific, and whether the reporting entity has characteristics that change the analysis.
A useful research sequence is: identify the transaction, determine the reporting entity, locate the relevant Topic and Subtopic, read scope and scope exceptions, then move to recognition, measurement, presentation, disclosure, and transition provisions.
For ASC 255, the main areas to research are:
When more than one Topic appears relevant, use the Codification’s scope guidance and relationships between Topics. For example, a transaction can involve an asset Topic, a broad-transaction Topic, and a presentation Topic at the same time. The correct answer may require all three, not a choice of only one.
Core Accounting Focus
The accounting objective is to produce a faithful, internally consistent application of U.S. GAAP to the specific facts. For this Topic, focus on four layers: recognition (whether and when an item enters the financial statements), measurement (the amount at which it is reported), presentation (where and how it appears), and disclosure (what additional information users need).
Not every Topic contains all four layers; some Topics are primarily presentation or disclosure guidance.
Documentation should identify the facts that drive the conclusion. Avoid copying a conclusion from another company without checking whether the asset characteristics, legal obligations, measurement basis, reporting environment, or reporting-entity status are the same.
A technically correct Topic number can still produce a wrong answer if the wrong Subtopic or scope paragraph is used.
A Practical ASC 255 Accounting Process
Define the Reporting Issue
Write a short factual description of the changing-price or inflation-related reporting issue without jumping to an accounting conclusion.
Confirm Scope
Determine whether ASC 255 applies and whether another Topic is more specific to the underlying transaction or financial-statement item.
Identify the Unit of Account
Determine what asset, liability, contract, obligation, instrument, business, or activity is being evaluated.
Apply Recognition Guidance
Decide whether an amount should be recognized now, later, or not at all under the applicable accounting model.
Apply Measurement Guidance
Determine initial and subsequent measurement under the relevant Topic, including any effects that require separate reporting analysis.
Record the Accounting
Prepare entries only after the recognition and measurement analysis is complete.
Present and Disclose
Determine financial-statement presentation, supplementary reporting, note disclosures, and any relevant qualitative information.
Check Other Topics and Updates
Review related Topics, SEC requirements for registrants, and Accounting Standards Updates that affect the conclusion or effective date.
Detailed Practical Example
Scenario
A reporting entity prepares its financial statements and evaluates how changing prices should be displayed or disclosed. The practical work is primarily presentation and disclosure rather than a single universal debit-and-credit entry.
Journal-Entry Approach
No single journal entry is universally associated with ASC 255. The underlying transactions are recorded under the relevant recognition and measurement Topics, while ASC 255 addresses the related supplementary reporting concepts.
Accounting Result
The purpose of this example is to demonstrate the research path rather than imply that every matter within ASC 255 is recorded the same way. Real situations can require more detailed calculations, estimates, valuation techniques, tax effects, presentation decisions, or disclosures.
Real-World Reporting Example
Microsoft Corporation
Microsoft’s public filings provide a real-company financial-reporting context for researching changing prices, while the exact applicability of ASC 255 depends on the facts and the relevant Codification Subtopics.
This example is used as a reporting context, not as a claim that every disclosure in the linked filing is governed exclusively by ASC 255. A company may apply several Topics to the same note.
When citing the company on the published page, verify the exact note, fiscal period, and wording in the primary filing and distinguish clearly between what the company states and Accountant Compass’s explanation of how the disclosure relates to the Topic.
How ASC 255 Can Affect the Financial Statements
This Topic often changes where and how information is displayed rather than creating the underlying asset, liability, revenue, or expense. Presentation decisions can still materially affect how users understand performance, liquidity, and risk.
| Statement Area | Questions to Ask |
|---|---|
| Balance sheet | Does the Topic create, remeasure, classify, offset, impair, or remove an asset, liability, or equity amount? |
| Income statement | Does the Topic affect revenue, expense, gains, losses, or the timing of recognition? |
| Cash flows | Is a related cash flow operating, investing, or financing, and are there noncash disclosures? |
| Equity / OCI | Does the Topic route changes through retained earnings, additional paid-in capital, or accumulated other comprehensive income? |
| Notes | What policies, judgments, estimates, supplementary information, or qualitative disclosures are required? |
Common Mistakes to Avoid
- Using the Topic title as the conclusion without reading the applicable Subtopic and scope exceptions.
- Relying on a secondary summary when the transaction involves a current effective date, transition rule, or specialized exception.
- Copying another company’s accounting policy without comparing the underlying facts.
- Confusing an Accounting Standards Update with a permanent standalone standard; ASUs amend the Codification.
- For SEC registrants, ignoring SEC rules and SEC material that may supplement U.S. GAAP.
- Using an old Topic number such as ASC 840 or a moved Topic as though it were the current primary model.

Frequently Asked Questions
What does ASC 255 cover?
ASC 255 covers supplementary reporting concepts related to changing prices and inflation. The detailed requirements depend on the relevant Subtopic, Section, and transaction facts.
Is ASC 255 part of U.S. GAAP?
The FASB Accounting Standards Codification is the authoritative source of nongovernmental U.S. GAAP recognized by FASB. A Topic page is a navigation level within that Codification; users must still research the applicable lower-level guidance.
Does ASC 255 always require a journal entry?
No. Some Topics focus primarily on presentation or disclosure, while others affect recognition and measurement. A journal entry should be prepared only when the underlying accounting model requires an amount to be recognized or remeasured.
Where should I verify the latest requirements?
Verify current guidance in the FASB Accounting Standards Codification and review recent Accounting Standards Updates and effective-date information. SEC registrants should also consider applicable SEC rules and interpretive material.
