Current expenditure includes final consumption expenditure (e.g. compensation of employees, consumption of intermediate goods and services, consumption of fixed capital, and military expenditure), property income paid, subsidies, and other current transfers paid (e.g. social security, social assistance, pensions and other welfare benefits).
It is usually fairly easy to obtain estimates of annual current expenditure on salaries and purchase of materials. It is more difficult to estimate the annual value of buildings and equipment. If the buildings are rented, the annual rent can be used to represent the value of the capital resources used during the year (Woodhall, 2004: 31)
