Offering details — type (IPO, secondary), SEC file number, form type (S-1, S-3), pricing/closing date
Audited financial statements — fiscal periods covered, audit report date
Unaudited interim financials — periods under review; pro forma data if applicable
Underwriting agreement — date, full legal names of all addressees, specific comfort items requested
Cut-off date — within 5 business days of comfort letter date
Engagement authorization — engagement letter authorizing preparation

Drafting Workflow

1. Header & Introduction

Firm letterhead with PCAOB registration number
Date coinciding with pricing or closing
Addressees: all underwriters/placement agents by full legal name
State purpose, registration statement number, audited periods, governing standard (PCAOB AS 6101), and underwriting agreement authorization

2. Scope & Procedures

Include required disclaimer: procedures do not constitute an audit or review under PCAOB standards and are substantially less in scope than an examination.

Standard procedures:

Read minutes of stockholders, board, and committee meetings through cut-off date
Inquire of officials re: changes in capital stock, long-term debt, specified financial statement items
Apply analytical procedures to interim data (comparison to prior periods)
Agree interim figures to accounting records
Read unaudited interim financials in the registration statement
If applicable: agreed-upon procedures on pro forma information

State cut-off period: from latest audited balance sheet date through cut-off date.

3. Negative Assurance Statements

Use consistently for each item requested in the underwriting agreement:

"Nothing came to our attention as a result of the foregoing procedures that caused us to believe that..."

| Topic | Completing clause | |---|---| | Financial statement items | ...material decreases in [item] vs. [audited period] | | Long-term debt | ...increase beyond [threshold / any material amount] | | Stockholders' equity | ...material decrease from [date] to cut-off date | | Interim financials | ...not prepared in conformity with GAAP on a basis consistent with audited statements | | Pro forma (if applicable) | ...adjustments not applied consistently with applicable SEC rules / GAAP [VERIFY: Reg S-X Rule 11-02] |

4. Limitations & Disclaimers

Solely for named addressees' use in their investigation
No third-party reliance without prior written consent
No opinion on sufficiency of procedures for underwriters' purposes
No responsibility for registration statement / prospectus disclosure adequacy
No assurance on legal matters or regulatory compliance beyond financial presentation
No obligation to update beyond cut-off date

5. Closing & Signature

Reaffirm limited assurance and reliance restrictions
Restrict inclusion in transaction documents and further distribution
Signature: firm name, authorized partner signature, "Certified Public Accountants," signing office location
If required: confirm PCAOB registration and independence compliance

Critical Rules

Negative assurance only — "nothing came to our attention" is the ceiling; never imply positive assurance
PCAOB AS 6101 — all procedures and formulations must conform; cite in introduction [VERIFY current designation]
Addressee specificity — letter is non-transferable; name all relying parties; comfort does not extend to unnamed parties
Cut-off discipline — do not extend assurance beyond the stated cut-off date
Independence — confirm PCAOB and SEC independence requirements before issuance
Pro forma — address separately under applicable Regulation S-X rules if included in registration statement [VERIFY]
Securities Act context — underwriters rely on comfort letters for Section 11 due diligence defense
Senior review required — flag for engagement partner review; do not finalize without attorney sign-off on limitations language
