How do you treat trapped cash in foreign structures as a source, and when is existing cash not effectively usable?

Trapped cash is cash that cannot be freely used because of tax, legal, regulatory, FX, minority shareholder, covenant, or operational restrictions. In S&U, only freely available cash should be shown as a source. Existing cash may be unusable if repatriation triggers withholding tax, local approvals, trapped minority economics, capital controls, or if the business needs it for minimum operating liquidity.
