Customer Agreements

Quick Answer

A principal approves every new account, but the customer signs nothing for a cash account. Margin needs Reg T's 50% initial and FINRA's 25% long / 30%+ short (steeper below $5/share) maintenance margin; options need the ODD at or before approval and the signed agreement back within 15 days. Registration is never approval, and agents cannot guarantee performance.

The whole unit on one sheet: what gets documented, who signs, the margin and options timing rules, and the two prohibited representations.


What Does Opening a New Account Require?

  • FINRA's account-information rule requires name, residence, legal age, the responsible associated person (non-institutional accounts only), and, for entities, authorized representatives. An SEC rule adds a fuller financial profile where the firm makes suitability determinations.
  • A principal of the firm must approve every new account. Approval is supervisory, not something the customer performs.
  • A cash account needs no customer signature to open; the firm opens and trades it on the gathered information plus principal approval.
  • For non-institutional accounts, the firm makes reasonable efforts to obtain tax ID, occupation, and employer before the initial transaction settles, not necessarily before opening.
  • An institutional account is a bank, insurer, registered investment company, registered adviser, or any person with at least $50 million in total assets, and it needs no TCP.
  • The firm furnishes a copy of the record within 30 days of opening, every 36 months after, and within 30 days of notice of a change in investment objectives.
  • The firm makes a reasonable effort to obtain a trusted contact person, a natural person 18 or older, for each non-institutional account. The customer may decline and still open it.

What Does a Margin Account Require?

  • The customer signs the margin agreement, promptly after the first margin transaction. The agreement does not have to precede that trade.
  • The credit agreement (loan terms) and hypothecation agreement (pledging collateral) are required; the loan consent agreement is optional.
  • The firm delivers a margin risk disclosure statement at or before opening: the customer can lose more than deposited, the firm can sell without contacting them, and requirements can change anytime.
  • Regulation T (Federal Reserve Board) sets initial margin at 50%. FINRA sets maintenance margin at 25% long, and short at the greater of $5/share or 30% of CMV (stock at or above $5), or $2.50/share or 100% of CMV (stock under $5), plus a $2,000 minimum equity floor.
  • A missed margin call lets the firm liquidate without notice. Rehypothecation is capped at 140% of the debit balance.

What Does an Options Account Require?

  • Deliver the Options Disclosure Document (ODD), published by the OCC, at or before options approval.
  • For a natural person, the firm exercises due diligence on objectives, employment, net worth, liquid net worth, marital status, age, and experience.
  • A qualified principal, ordinarily a Registered Options Principal (ROP), must approve the account before the first options trade. A non-qualified branch manager may approve initially, but an ROP or Limited Principal-General Securities Sales Supervisor must confirm within 10 business days.
  • Two separate 15-day clocks start at approval: the customer signs and returns the options agreement, and the firm sends background and financial information for verification (deemed verified absent contrary notice).
  • Pricing shorthand: premium = intrinsic value + time value, intrinsic value never below zero, calls in-the-money above the strike and puts below.

Which One-Liners Win Points?

  • Registration becomes effective; it is never approved. An agent may truthfully say a registration is effective, but may not imply approval, endorsement, or merit review.
  • Guaranteeing against loss, promising a specific return, or sharing in a customer's losses to cushion a bad investment is prohibited, even without the word "guarantee." Describing an issuer feature ("this bond pays a 5% coupon") is fine; an agent guaranteeing an outcome is not.

Which Numbers Matter Most?

Rehypothecation cap140% of debit balance
Options agreement returned, and info sent for verificationwithin 15 days each
Account record furnished after opening, then thereafterwithin 30 days, every 36 months
Institutional account asset threshold$50 million

What Is the Memory Aid for Registration Versus Endorsement?

Registration does not equal Endorsement. Registration is a legal filing; endorsement is a quality judgment. The Administrator does one, never the other.

Which Gotchas Trip Students Up?

  • ODD timing: at or before options-account approval, never afterward.
  • Do not confuse principal approval (every account) with the customer signature (only margin and options).
  • Reg T sets initial margin; FINRA sets maintenance margin.

One-Breath Recap

A principal approves every new account, but the customer signs nothing to open a cash account, while the firm still furnishes the account record within 30 days and every 36 months after. A margin account needs the margin agreement signed promptly after the first margin transaction, Reg T's 50% initial margin, FINRA's 25%/30% maintenance margin, and a $2,000 equity floor. An options account needs the Options Disclosure Document delivered at or before approval, an options-qualified principal to approve, and the signed agreement and verification both returned within 15 days. The firm makes a reasonable effort to name a trusted contact person aged 18 or older. Two lines never move: registration is effective, never approved, and no agent may guarantee against loss or cushion a customer's losses.
