Explanation:

According to the CFA Institute Standards of Professional Conduct, specifically Standard III(A): Loyalty, Prudence, and Care, members who have control of client assets must provide clients with itemized statements of their security holdings and transactions at least quarterly. This requirement ensures transparency and allows clients to monitor their investments regularly.

Key Points:

1. Standard III(A) Requirements: When members have custody of client assets, they must provide regular account statements to clients.
2. Frequency: The minimum requirement is quarterly (every three months).
3. Purpose: This ensures clients can verify holdings, monitor transactions, and detect any discrepancies or unauthorized activities.
4. Best Practice: While quarterly is the minimum, many firms provide monthly or even more frequent statements as a best practice.

Why not semi-annually or annually?

• Semi-annually (every 6 months) and annually (every 12 months) are less frequent than the required minimum.
• Longer intervals between statements reduce transparency and increase the risk of undetected errors or misconduct.
• The quarterly requirement balances administrative burden with adequate client protection.
