Stock brokers' networth rules require base or higher variable networth with segment-specific minimums and computation rules. Regulation 47 requires members to maintain either specified base networth thresholds or a higher variable networth (not applicable to Execution Only Platforms), with segment-specific minima for Currency Derivatives. Networth is reckoned across all segments. Base networth comprises paid-up capital, certain convertible instruments, free reserves and Board-approved securities, and excludes fixed assets, pledged/unallowable securities, most debts, prepaid expenses, losses, intangibles and 30% of marketable securities. Post-haircut pledged shares and higher sectoral regulator standards apply where relevant.
