Think of SA 260 as the official conversation rulebook between the auditor and the people who run the company at the top — not the day-to-day managers, but the Board of Directors, Audit Committee, or Managing Committee. These people are called Those Charged with Governance (TCWG). The standard exists because an audit isn't done in silence — the auditor must keep the right people informed, at the right time, about the right things.
SA 260 tells the auditor what to communicate, to whom, when, and how. The four big things the auditor must communicate to TCWG are: (1) the auditor's responsibilities under SA — basically, what the auditor is and isn't responsible for; (2) the planned scope and timing of the audit — not every detail, but enough for TCWG to understand the overall approach; (3) significant findings from the audit — this includes significant difficulties encountered, significant matters arising, written representations requested, and any uncorrected misstatements; and (4) auditor's independence — especially critical when the auditor or firm has provided non-audit services.
A super important nuance: management ≠ TCWG. In a large listed company like Reliance Industries, the CFO (management) and the Audit Committee (TCWG) are different people. But in a small private company like Sharma Textiles Pvt. Ltd., the same person — Mr. Sharma — may be both the owner-manager and the sole director. SA 260 says that in such cases, if all TCWG members are also part of management, the auditor need not communicate separately to TCWG what has already been communicated to management. This is a frequently tested distinction in 4-mark and 8-mark questions.
On timing: communication should be timely — not after the audit report is signed. Significant matters should be flagged early enough for TCWG to act. On form: oral communication is acceptable, but significant matters must be in writing. If the auditor decides to communicate orally, the file must document what was communicated, when, and to whom. SA 260 doesn't prescribe a fixed format, but the communication must be clear and not misleading.
