Representations and Warranties Insurance in M&A

R&W insurance transfers post-close risk from the seller's indemnification obligations to a third-party insurer. Covers policy types, premium costs, coverage scope, and exclusions.

Quick answer

Representations and warranties (R&W) insurance transfers the risk of seller's breaches of representations from the purchase agreement's indemnification provisions to a third-party insurer. Buyer-side policies are most common (90%+ of policies). Coverage typically runs 3–6 years, with premiums of 2–4% of policy limits. PwC reports that R&W insurance is now used in over 50% of middle-market PE deals, enabling cleaner exits for sellers (minimal escrow) while protecting buyers against unknown liabilities. Key exclusions: known issues identified during DD, forward-looking projections, and certain tax items.

R&W insurance has transformed M&A deal mechanics. What was once a niche product is now standard in middle-market PE deals — used in over 50% of transactions.

How R&W Insurance Works

The Problem It Solves

  • Seller makes representations — "The financial statements are accurate," "There is no undisclosed litigation," "The company complies with all laws"
  • Buyer discovers a breach post-close — Financial statements contained material errors
  • Buyer seeks indemnification — Claims against the seller per the purchase agreement
  • Seller resists — Disputes, litigation, delays, potential inability to pay

R&W insurance replaces this adversarial dynamic with an insurance claim.

Buyer-Side vs. Seller-Side Policies

  • Buyer is the insured party and makes claims directly against the insurer
  • Seller provides minimal or no indemnification (clean exit)
  • Buyer gets faster, more certain recovery
  • Seller avoids post-close liability
  • Seller is the insured party
  • Insurer backstops seller's indemnification obligations
  • Less popular because buyer still must pursue the seller first

Policy Economics

Premium

Premiums run 2–4% of policy limits:

Policy LimitPremium RangeTypical Premium
$5M$100K–$200K$150K
$10M$200K–$400K$300K
$25M$500K–$1M$750K
$50M$1M–$2M$1.5M

Retention (Deductible)

  • Typically 1% of enterprise value
  • Often steps down to 0.5% after 12–18 months
  • Shared between buyer retention and seller indemnification in some structures

Coverage Period

  • General representations: 3 years
  • Fundamental representations (title, authority, capitalization): 6 years
  • Tax representations: Duration of applicable statute of limitations

What R&W Insurance Covers

  • Undisclosed liabilities not identified during DD
  • Inaccurate financial statements (unknown errors)
  • Undisclosed pending or threatened litigation
  • IP ownership defects (unknown assignment gaps)
  • Tax positions that prove incorrect post-close
  • Regulatory non-compliance not identified during DD
  • Environmental liabilities (with enhanced coverage endorsement)
  • Employee benefit plan deficiencies

What R&W Insurance Excludes

  • Known issues identified during DD and disclosed in the disclosure schedules
  • Forward-looking projections, forecasts, and estimates
  • Purchase price adjustments (NWC true-ups — covered by the PA mechanism)
  • Consequential and punitive damages (unless specifically endorsed)
  • Fraud by the insured party
  • Certain transfer pricing and net operating loss items

Key principle: R&W insurance covers *unknown* unknowns discovered post-close. It does not cover known issues that the buyer accepted during DD.

The DD Connection

R&W insurers conduct their own underwriting diligence:

  1. 1. Review the buyer's DD reports — QoE, legal DD, tax DD, environmental
  2. 2. Assess DD quality — More thorough DD = better coverage terms
  3. 3. Identify coverage gaps — Issues where DD was insufficient may be excluded
  4. 4. Underwriting call — 1–2 hour call with the deal team to discuss DD scope and findings

Critical insight: The quality of the buyer's DD directly affects R&W insurance terms. Thorough DD leads to broader coverage and fewer exclusions.

The Bottom Line

R&W insurance is not a substitute for DD — it is a complement. Thorough DD identifies known issues (negotiated into the purchase agreement). R&W insurance protects against unknown issues discovered post-close. Together, they create a comprehensive risk management framework for M&A transactions.
