Basic Extraordinary EPS: Historical Definition and Status

Basic Extraordinary is the EPS component from extraordinary items, eliminated from US GAAP in 2015. Relevant only for pre-2015 historical financial analysis.

Basic Extraordinary refers to the component of basic earnings per share (EPS) that was attributable to extraordinary items—events deemed both unusual in nature and infrequent in occurrence. This line isolated the after-tax, per-share effect of such rare events using only the basic weighted average shares outstanding. The extraordinary items classification was eliminated from US GAAP in 2015 (ASU 2015-01), so this category no longer exists in contemporary financial statements and is relevant only for analyzing pre-2015 historical data.

What Were Extraordinary Items?

Under pre-2015 US GAAP (APB Opinion 30), extraordinary items had to meet strict dual criteria:

  • Unusual nature: Abnormal and unrelated to ordinary activities.
  • Infrequency of occurrence: Not expected to recur in the foreseeable future.

Qualifying examples were rare: major losses from natural disasters in non-prone areas, government expropriations, or effects of significant new legislation. These were reported net of tax, separately from continuing and discontinued operations, to prevent distortion of core earnings.

Basic Extraordinary showed this impact using basic shares only, providing a direct view for existing common shareholders without dilution assumptions.

Elimination of Extraordinary Items

In 2015, the FASB removed the extraordinary classification via ASU 2015-01 because:

Reasons for Removal

  • Very few events truly met both strict criteria.
  • Judgment led to inconsistent application across companies.
  • Investors preferred footnote disclosures over separate presentation.
  • Simplification of financial reporting.

Post-2015, such events are now reported within income from continuing operations (often as unusual or infrequent items) with detailed footnote disclosure if material.

IFRS has never permitted a separate extraordinary items category.

Historical Calculation

Formula: Basic Extraordinary = (After-tax Extraordinary Gain or Loss) ÷ Basic Weighted Average Shares Outstanding

The amount was always presented net of tax and calculated independently of other EPS components.

Historical Examples

Example 1: Rare Natural Disaster

Company incurs 52.5M.

After-tax loss: 0.8125 per share.

Example 2: Asset Expropriation

Government seizes assets abroad, resulting in $60M after-tax loss.

Basic shares: 80M. Basic Extraordinary = −$0.75 per share. Appeared below discontinued operations in pre-2015 statements.

Today, these would be included in operating/non-operating income with footnote explanations.

Relevance Today vs. Historical Analysis

In modern financial statements (post-2015), this line is always zero. Similar events are now part of continuing operations and often adjusted in non-GAAP normalized earnings.

For pre-2015 historical analysis:

  • Explains significant one-time EPS impacts
  • Should be excluded for normalized or core basic EPS
  • Aids accurate long-term trend evaluation

Warning: Including historical extraordinary items in trend analysis without adjustment can mislead about ongoing performance.

Q · 01
What is Basic Extraordinary in earnings per share?
A · TL;DR
Basic Extraordinary is the basic EPS line that isolated the after-tax per-share effect of extraordinary items—events deemed both unusual and infrequent under pre-2015 US GAAP accounting rules.
Q · 02
Why was the extraordinary items EPS classification eliminated?
A · TL;DR
FASB removed it via ASU 2015-01 because very few events met both strict criteria, companies applied the rules inconsistently, and investors preferred footnote disclosures over separate presentation.
Q · 03
Does Basic Extraordinary appear on current financial statements?
A · TL;DR
No. US GAAP eliminated extraordinary items in 2015. Post-2015 statements report similar unusual events within continuing operations with footnote disclosure. IFRS never permitted this category.
Q · 04
How was Basic Extraordinary calculated historically?
A · TL;DR
After-tax extraordinary gain or loss was divided by basic weighted average common shares outstanding. The amount always appeared net of tax, separately from continuing and discontinued operations.
Q · 05
How should analysts handle Basic Extraordinary in historical trend analysis?
A · TL;DR
Exclude it from normalized or core basic EPS when building long-term trend comparisons, as extraordinary items were one-time events not reflective of ongoing operational performance.
