PMBOK Guide 5th Edition:
Budget within cost baseline or performance measurement baseline that is allocated for identified risks that are accepted and for which contingent or mitigated responses are developed.

AACE, Skills and Knowledge of Cost Engineering, 6th Edition:
"An amount added to an estimate to allow for items, conditions, or events for which the state, occurrence, or effect is uncertain and that experience shows will likely result, in aggregate, in additional costs".
