What must be calculated when any portion of the money balance in a cash account...

When a cash-account money balance remains overdue for fewer than six business days after the regular settlement date, the applicable calculation is the equity deficiency . CIRO Form 1 specifies that this deficiency is determined by comparing the net weighted market value of the settlement-date investment-product positions in the client’s cash accounts with the net money balance calculated on a settlement-date basis. Option B expresses this regulatory calculation, although it abbreviates “net weighted market value” as “net weighted security value” and “net money balance” as “net cash.”

The calculation is not based on the account’s total cash balance, the gross market value of all securities, or trading volume. Those figures do not measure whether the overdue debit is adequately supported by eligible securities after the prescribed regulatory weightings have been applied. Different weightings may apply depending on the margin eligibility and risk characteristics of the securities held.

This requirement falls within the Retail Securities syllabus coverage of the cash-account rule, overdue cash accounts, settlement and delivery, and special margin situations. CIRO Form 1, Part II, Schedule 4 specifically prescribes the equity-deficiency calculation for balances overdue by fewer than six business days.
