SIE Exam: Customer Communications

Section 3 — Understanding Trading, Customer Accounts and Prohibited Activities (31% of exam)

The SIE exam tests how broker-dealers communicate with customers and the public, including the regulatory framework governing corporate actions that affect customer positions. Customer communications fall into three categories under FINRA rules: institutional communications (to institutional investors), retail communications (to more than 25 retail persons within 30 calendar days), and correspondence (to 25 or fewer retail persons). Each category has different approval and filing requirements. Retail communications generally require principal pre-approval, while correspondence may be reviewed after use. The exam covers the impact of corporate actions on customer accounts, including stock splits (forward and reverse), stock dividends, cash dividends, rights offerings, tender offers, mergers, spin-offs, and share buybacks. You must understand the chronological order of dividend dates (declaration, ex-dividend, record, payable) and how these events affect share count, price, and cost basis. Tender offer rules require a minimum 20 business day open period. Knowledge of how rights offerings work — including subscription prices set below market and standby underwriting — is essential for the SIE.

Key Concepts

Retail Communication

Any written communication distributed to more than 25 retail persons within 30 calendar days. Requires principal pre-approval and may require FINRA filing.

Forward Stock Split

Increases shares outstanding and proportionally decreases price per share. A 2-for-1 split doubles shares and halves the price, keeping total value unchanged.

Reverse Stock Split

Decreases shares outstanding and increases price per share. Often used by companies to meet exchange minimum price requirements.

Dividend Dates

Declaration date (board announces), ex-dividend date (same calendar day as the record date under T+1 settlement, effective May 28, 2024), record date (determines eligible shareholders), payable date (dividends paid).

Tender Offer

A public bid to purchase shares from existing shareholders, usually at a premium. Must remain open for a minimum of 20 business days.

Spin-Off

A parent company distributes shares of a subsidiary to existing shareholders. Similar to a stock dividend, the shareholder's cost basis must be allocated between the two holdings.
