Cash Withdrawal via SMA: Debit Balance and Equity Impact

An investor has an account with LMV $50,000, DR $20,000, EQ $30,000, and SMA $5,000. If the customer withdraws $3,000 in cash from the account, what are the new DR, EQ, and SMA balances?

Correct Choice: A

When cash is withdrawn using SMA: (1) Cash withdrawal increases the loan from the firm: DR increases by $3,000 to $23,000. (2) Customer equity drops dollar-for-dollar: EQ drops by $3,000 to $27,000. (3) SMA is reduced dollar-for-dollar: SMA drops by $3,000 to $2,000.

Complete Analysis & Legal Rationale

Cash is borrowed from the broker-dealer. Assets (LMV) remain $50,000. Liabilities (DR) expand to $23,000. Net Equity = $50,000 - $23,000 = $27,000. SMA remaining = $5,000 - $3,000 = $2,000.

Mathematical Step-by-Step Derivation

  1. Step 1: New DR = $20,000 + $3,000 = $23,000 (loan increases).
  2. Step 2: New EQ = $30,000 - $3,000 = $27,000 (equity drops).
  3. Step 3: New SMA = $5,000 - $3,000 = $2,000 (SMA reduces).

Distractor Autopsy (Why Other Options Are Traps)

FINRA exam writers design incorrect distractors using specific calculation mistakes and regulatory misconceptions. Review why each option succeeds or fails:

Choice ACorrect
Accurate Accounting

Accurately adjusts all three balance sheet items: DR up $3k, EQ down $3k, SMA down $3k.

Choice BIncorrect
Debit Inversion Error

Reduces debit balance instead of increasing it.

Choice CIncorrect
Static Balance Fallacy

Leaves DR and SMA unchanged.

Choice DIncorrect
Violating Balance Equation

Leaves equity unchanged, which violates the accounting equation.
