Income Taxes [Abstract]

Computation of Effective Income Tax Rate and Changes in Components of Income Tax

Holding’s income tax is computed by multiplying certain AllianceBernstein qualifying revenues (primarily U.S. investment advisory fees and brokerage commissions) by Holding’s ownership interest in AllianceBernstein, multiplied by the 3.5% tax rate. Holding Units in AllianceBernstein’s consolidated rabbi trust are not treated as outstanding for purposes of calculating Holding’s ownership interest in AllianceBernstein.
