ASC 260
Active
Earnings Per Share
Governs the calculation and presentation of earnings per share (EPS), including basic EPS, diluted EPS, and the treasury stock and if-converted methods.
1
Conceptual Framework Linkage
The most widely watched single number in financial reporting
Earnings per share condenses an entity's overall performance into a single, per-share figure investors use constantly for valuation and comparison. ASC 260 exists to ensure this figure is calculated CONSISTENTLY and MEANINGFULLY – particularly capturing the POTENTIAL dilutive effect of securities that could convert into common shares, so users see both a "basic" and a fully "diluted" view of earnings capacity per share.
A genuine product of joint FASB-IASB standard-setting
ASC 260 and its IFRS counterpart, IAS 33, emerged from an EARLY 2000s joint FASB-IASB convergence project specifically targeting EPS mechanics – as a result, the two standards are among the MOST closely aligned pairs in the entire Codification, sharing nearly identical treasury stock method, if-converted method, and antidilution mechanics, with the two-class method (Section 9) standing out as the principal remaining divergence.

Scope & Applicability
Public companies (and public common-stock-holding entities) primarily
ASC 260 applies to entities whose common stock or potential common stock is PUBLICLY HELD, or that have filed (or are in the process of filing) with the SEC. PRIVATE companies are generally NOT required to present EPS, though many elect to do so voluntarily – broadly mirroring IAS 33's own scope, which similarly focuses mandatory application on entities whose shares are publicly traded or in the process of being issued to the public.

Basic EPS
The starting-point calculation
BASIC EPS FORMULA
Basic EPS = (Net income attributable to common shareholders − Preferred dividends) ÷ Weighted-average common shares outstanding
The WEIGHTED-AVERAGE number of common shares outstanding reflects shares actually outstanding during each portion of the period, time-weighted – the identical mechanical concept IAS 33 uses.
4
Diluted EPS – the As-If-Converted Principle
Capturing the maximum potential dilution
DILUTED EPS reflects the POTENTIAL dilution that could occur if all DILUTIVE potential common shares (stock options, warrants, convertible securities, contingently issuable shares) were converted into common stock – computed AS IF such conversion had occurred at the beginning of the period (or issuance date, if later). This "as-if-converted" principle is identical in substance to IAS 33's own diluted EPS mechanics.
5
Treasury Stock Method – Options & Warrants
The same method used under IAS 33
For OPTIONS and WARRANTS, the TREASURY STOCK METHOD assumes the proceeds from exercise are used to REPURCHASE shares at the AVERAGE MARKET PRICE during the period – the net INCREMENTAL shares (shares issued upon exercise minus shares assumed repurchased) are added to the diluted EPS denominator. This is the SAME method, applied the SAME way, under IAS 33 – one of the most precisely converged mechanics between the two frameworks.
6
If-Converted Method – Convertible Securities
Also identical in substance to IAS 33
For CONVERTIBLE preferred stock and CONVERTIBLE debt, the IF-CONVERTED method assumes conversion occurred at the beginning of the period: convertible preferred dividends are ADDED BACK to the numerator (since they would no longer be paid), convertible debt's after-tax INTEREST expense is added back to the numerator, and the AS-IF-CONVERTED common shares are added to the denominator – again, the same fundamental mechanic IAS 33 applies.
7
Antidilution
Excluding securities that would improve, not worsen, EPS
A potential common share is EXCLUDED from the diluted EPS calculation if including it would be ANTIDILUTIVE – i.e. if it would INCREASE EPS (or decrease loss per share) rather than reduce it. Each potential common share category is tested INDIVIDUALLY for dilutive effect, and antidilutive securities are simply left out entirely, consistent with IAS 33's identical antidilution testing principle.
8
Contingently Issuable Shares
Included based on conditions as of period end
Shares issuable upon the satisfaction of specified CONDITIONS (e.g. an earnings target, a market price target) are included in DILUTED EPS based on the number of shares that WOULD be issuable if the end of the reporting period were the end of the contingency period – broadly mirroring IAS 33's own treatment of contingently issuable shares.
9
The Two-Class Method
A distinctly US GAAP concept, with no IAS 33 equivalent
When an entity has PARTICIPATING SECURITIES – securities (such as certain preferred stock, or unvested share-based payment awards) that participate in DIVIDENDS with common stock according to a predetermined formula – ASC 260 REQUIRES the TWO-CLASS METHOD: earnings are ALLOCATED between common stock and the participating securities based on their respective rights to receive dividends (and undistributed earnings), and EPS is computed for EACH class separately. IAS 33 has NO directly equivalent named method – participating instruments under IFRS are analysed under general EPS principles without an equivalent formal "two-class" allocation methodology, making this the single most significant EPS-specific divergence between the two frameworks.
10
Presentation Requirements
Face-of-statement disclosure
Basic and diluted EPS must be presented on the FACE of the Income Statement, for INCOME FROM CONTINUING OPERATIONS and for NET INCOME, with equal prominence – and separately for discontinued operations, if applicable, either on the face or in the notes. This mirrors IAS 33's own face-of-statement presentation requirement closely.
11
Worked Example – Basic EPS
A straightforward calculation
Example: Net income with preferred dividends
Net income for the year is $20,000,000. Preferred dividends of $2,000,000 were declared. The weighted-average number of common shares outstanding during the year was 9,000,000.
Basic EPS = ($20,000,000 − $2,000,000) ÷ 9,000,000 = $2.00 per share.
12
Worked Example – Diluted EPS If-Converted Method
Adjusting for convertible debt
Example: Convertible bonds
Continuing the example above (net income $20,000,000, preferred dividends $2,000,000, 9,000,000 weighted-average common shares), the entity also has $10,000,000 of 5% convertible bonds outstanding all year, convertible into 800,000 common shares, with a 25% tax rate.
After-tax interest add-back = $10,000,000 × 5% × (1 − 25%) = $375,000.
Diluted EPS numerator = $20,000,000 − $2,000,000 + $375,000 = $18,375,000.
Diluted EPS denominator = 9,000,000 + 800,000 = 9,800,000.
Diluted EPS = $18,375,000 ÷ 9,800,000 = $1.87 per share (rounded) – lower than basic EPS of $2.00, confirming the convertible bonds are DILUTIVE and correctly included.
Diluted EPS numerator = $20,000,000 − $2,000,000 + $375,000 = $18,375,000.
Diluted EPS denominator = 9,000,000 + 800,000 = 9,800,000.
Diluted EPS = $18,375,000 ÷ 9,800,000 = $1.87 per share (rounded) – lower than basic EPS of $2.00, confirming the convertible bonds are DILUTIVE and correctly included.
13
Worked Example – the Two-Class Method
Allocating earnings between common stock and a participating security
Example: Participating preferred stock
An entity has net income of $10,000,000, 4,000,000 weighted-average common shares outstanding, and participating preferred stock entitled to dividends on an as-if-converted basis equivalent to 1,000,000 common shares (no separate convertible feature complications). Total shares on a combined basis: 5,000,000.
Under the two-class method, the $10,000,000 is ALLOCATED between common and participating preferred based on their PARTICIPATION RIGHTS: common stock's share = $10,000,000 × (4,000,000 ÷ 5,000,000) = $8,000,000. Basic EPS for common stock = $8,000,000 ÷ 4,000,000 = $2.00 per share – computed by ALLOCATION rather than by the if-converted method IAS 33 preparers would more likely apply to an economically similar instrument.

ASC 260 vs IAS 33 – the Two-Class Method Divergence
Comparison – ASC 260 vs IAS 33
FeatureUS GAAP (ASC 260)IFRS (IAS 33)
Treasury stock method (options/warrants)Yes, identical mechanicsYes – fully converged
If-converted method (convertibles)Yes, identical mechanicsYes – fully converged
Two-class method for participating securitiesSPECIFICALLY REQUIRED, with its own defined allocation methodologyNo equivalent named method – participating instruments assessed under general EPS principles instead
Scope (public vs private entities)Mandatory for public entities/SEC filers; optional for private companiesMandatory for entities whose shares are publicly traded or in the process of being issued publicly – a closely parallel scope test
Given the joint development history, ASC 260 and IAS 33 are among the closest-converged standard pairs across the two frameworks – the two-class method is genuinely the standout exception rather than the norm.
