संजातादायव्ययविशुद्धा नीवी प्राप्ता चानुवृत्ता च ॥ कZ_०२.६.२७ ॥
saṃjātādāyavyayaviśuddhā nīvī prāptā cānuvṛttā ca
Nīvī (the reserve/working capital of the treasury) is what remains purified (net) after income and expenditure have been accounted for; it is both realized and carried forward.
It must be actually realized in accounts (not merely projected) and then rolled forward as a continuing reserve for future operations.
