Earnings Per Share
 
Accounting Policy

The Company computes earnings per share (EPS) using the two-class method, which is an earnings allocation formula that determines EPS for: (i) each class of common shares (the Company has a single class of common shares); and (ii) participating securities according to dividends declared (or accumulated) and participation rights in undistributed earnings. Awards and share units under the AGS SERP with non-forfeitable dividends are considered participating securities.

Basic EPS is computed by dividing net income (loss) available to common shareholders of Assured Guaranty by the weighted average number of common shares outstanding during the period. Diluted EPS adjusts basic EPS for the effects of restricted stock, restricted stock units, stock options and other potentially dilutive financial instruments (dilutive securities) only in the periods in which such effect is dilutive. The effect of the dilutive securities is reflected in diluted EPS by application of the more dilutive of: (1) the treasury stock method; or (2) the two-class method assuming nonvested shares are not converted into common shares.

About Earnings Per Share Disclosures

The earnings per share disclosure breaks down the calculation from net income to both basic and diluted EPS, revealing the full impact of a company's capital structure on per-share economics. The reconciliation between basic and diluted share counts exposes how many stock options, RSUs, convertible securities, and warrants are potentially dilutive to existing shareholders.

Key signals: a widening gap between basic and diluted shares indicates growing dilution from equity compensation or convertible instruments. Anti-dilutive securities excluded from the diluted calculation deserve attention — they represent latent dilution that will materialize if the stock price rises. Watch for the effect of share buybacks on per-share metrics: EPS growth driven primarily by repurchases rather than income growth signals weakening fundamentals. Compare year-over-year changes in the diluted share count against equity compensation expense to assess whether management is effectively managing dilution.
