Fundamental accounting concept relations: Reasons Why Fundamental Accounting Concept Relations Fail
This set of documents provides information which is useful in interpreting fundamental accounting concept relation violations:
- Overview: Interpretation of Fundamental Accounting Concept Test Results
- Fundamental accounting concepts: This is a list of the fundamental accounting concepts and the relations between those concepts.
- Mapping rules: This is a human readable version of the mappings between the fundamental accounting concepts and US GAAP XBRL Taxonomy Concepts.
- Imput rules: These are the rules used to impute facts which have not been reported within a financial report.
- Required to be reported and allowed to be extended: Some concepts may be required to be reported, others are optional. Some concepts may be extended, others may not. The point is that concepts behave differently. Be aware of this.
- Summary of Conformance with Fundamental Accounting Concepts: Summary information related to how well public companies conform to the fundamental accounting concept relations.
- Pass all tests: A good way to understand the reasons why reporting entities do not conform to these fundamental accounting concepts is to understand why they satisfy all of these fundamental relations. This document walks you thorugh that process.
- Example Analysis of Conformance Test: This is an analysis of one fundamental accounting concept conformace test. It helps you understand how to think about these tests. This shows an analysis of IS3. This same sort of analysis can be done for every one of these fundament accounting concept relation rules/tests.
- Balance sheet
- BS1: Equity = Equity Attributable to Parent + Equity Attributable to Noncontrolling Interest
- BS2: Assets = Liabilities and Equity
- BS3: Assets = Current Assets + Noncurrent Assets (classified balance sheet)
- BS4: Liabilities = Current Liabilities + Noncurrent Liabilities (classified balance sheet)
- BS5: Liabilities and Equity = Liabilities + Commitments and Contingencies + Temporary Equity + Redeemable Noncontrolling Interest + Equity

- IS1: Gross Profit = Revenues - Cost of Revenues
- IS2: Operating Income (Loss) = Gross Profit - Operating Expenses + Other Operating Income (Expenses) (Multi-step approach)
- IS3: Income (Loss) from Continuing Operations Before Equity Method Investments = Operating Income (Loss) + Nonoperating Income (Loss) - Interest And Debt Expense
- IS4: Income (Loss) from Continuing Operations Before Tax = Income (Loss) from Continuing Operations Before Equity Method Investments + Income (Loss) from Equity Method Investments
- IS5: Income (Loss) from Continuing Operations after Tax = Income (Loss) from Continuing Operations Before Tax - Income Tax Expense (Benefit)
- IS6: Net Income (Loss) = Income (Loss) from Continuing Operations After Tax + Income (Loss) from Discontinued Operations, Net of Tax + Extraordinary Items, Gain (Loss)
- IS7: Net Income (Loss) = Net Income (Loss) Attributable to Parent + Net Income (Loss) Attributable to Noncontrolling Interest
- IS8: Net Income (Loss) Available to Common Stockholders, Basic = Net Income (Loss) Attributable to Parent - Preferred Stock Dividends and Other Adjustments
- Statement of comprehensive Income
- Cash flow statement
- CF1: Net Cash Flow = Net Cash Flows, Operating + Net Cash Flows, Investing + Net Cash Flows, Financing + Exchange Gains (Losses)
- CF2: Net Cash Flows, Continuing = Net Cash Flows, Operating, Continuing + Net Cash Flows, Investing, Continuing + Net Cash Flows, Financing, Continuing
- CF3: Net Cash Flows, Discontinued = Net Cash Flows, Operating, Discontinued + Net Cash Flows, Investing, Discontinued + Net Cash Flows, Financing, Discontinued
- CF4: Net Cash Flows, Operating = Net Cash Flows, Operating, Continuing + Net Cash Flows, Operating, Discontinued
- CF5: Net Cash Flows, Investing = Net Cash Flows, Investing, Continuing + Net Cash Flows, Investing, Discontinued

- Report Frames and Report Frames (i.e. different industry/activity reporting styles and filer presentation styles): Most companies are commercial and industrial, about 85% of public companies. However, there are industries/activities which have specific reporting styles. Also, some companies report using a single step income statement and others use a multi-step approach. Some companies report operating income (loss) while othere so not. Each of these groupings is called a "report frame":
- Disclosures (handful of examples) (Disclosures Viewer) (Another Disclosure Viewer)
- Nature of operations, basis of reporting, significant accounting policies, revenue recognition policy
- Accounts receivable net roll up
- Capitalized computer software, net, roll forward
- Finite lived intangible assets estimated useful lives
- Long lived assets by geographic area
- Property, plant and equipment estimated useful lives
- Property, plant and equipment components by type roll up
- Long term debt maturities roll up
- Future minimum payments under operating leases
- Future minimum payments under capital leases
- Deferred tax asset (liability) net
- Others (coming soon)
- Other information: This is other helpful information to help you think through the process of the reasons why fundamental accounting concept relations tests fail.
- Digital Disclosure Checklist Summary: The fundamental accounting concepts are useful, but only an example of where all this is headed. Digital financial reports are not useful if 22 relations are correct, there are thousands of relations in every financial report. This Digital Disclosure Checklist Summary will help you realize where all this is headed.
