संजातादायव्ययविशुद्धा नीवी प्राप्ता चानुवृत्ता च ॥ कZ_०२.६.२७ ॥
saṃjātādāyavyayaviśuddhā nīvī prāptā cānuvṛttā ca
Nīvī(国库的储备/营运资本)是指在核算收入与支出之后所剩下的净额;它既是已实现的余额,也会结转到以后。
It must be actually realized in accounts (not merely projected) and then rolled forward as a continuing reserve for future operations.
