Capex Budget

I. Formal Definition

The portion of the approved budget allocated to capital expenditure, distinct from the operating expense budget. Capex budgets carry typically multi-year approval and require business case documentation tied to the capital allocation framework. The federation requires capex budgets to be linked to specific capital projects with approved business cases, with maintenance capex distinguished from growth capex per the capital allocation policy under UFMS-001:4.1. Project-level capex variance is reviewed at quarterly capex council meetings.

II. Etymology

A natural extension of the capex abbreviation into budget vocabulary; the construction stabilised in mid twentieth century industrial accounting.

III. Federation Usage

Federation members publish capex budget by project with approved business cases and maintenance versus growth split. Quarterly capex council reviews variance and reauthorisations under MEV-Annex:5.1. Project-level capitalisation is reconciled to the engineering register.
