Directors and officers (D&O) liability insurance is a claims‑made product designed to protect corporate leaders — and sometimes the company — from claims alleging wrongful acts. Endorsements such as run‑off (tail) coverage, Side C / Entity coverage, and related entity endorsements are not one‑size‑fits‑all. Knowing when to add them can protect founders, boards and balance sheets in high‑risk events like M&A, bankruptcy, regulatory enforcement, and shareholder litigation.
This article — focused on U.S. companies (New York, California, Texas examples included) — explains when each endorsement is appropriate, typical costs, negotiation tips, and use cases for in‑market insurers and brokers (Aon, Marsh, Chubb, Hiscox, Travelers).
Quick glossary
- Run‑off (Tail) / Extended Reporting Period (ERP): Extends the time to report claims arising from acts that occurred during the policy period after the policy terminates.
- Side A: Pays individual directors and officers when the company cannot indemnify them.
- Side C (Entity) coverage: Covers the company itself for securities claims or certain entity exposures (often excluded for public companies).
- Entity coverage endorsement: A policy language change or add‑on that broadens the company’s coverage (similar to or inclusive of Side C).
When to add Run‑off (Tail) Coverage
Add a run‑off endorsement when the corporate entity or its insured persons are exiting a period of heightened claim risk and you need protection after the policy cancellation or nonrenewal.
Common U.S. scenarios:
- Mergers & Acquisitions (seller-side): If your New York or California startup is being sold and the buyer won’t assume D&O liability, the seller should buy a run‑off (often called seller’s tail). Without it, claims that emerge post‑close (e.g., securities suits) may leave former directors exposed.
- Bankruptcy / Chapter 11: In Texas oil & gas firms or manufacturing firms entering insolvency, run‑off is critical because the company cannot indemnify directors later.
- Wind‑down / Liquidation: Private companies that cease operations but face potential historical claims.
- Board turnover after restatement or regulatory probe: If a company expects securities litigation or SEC scrutiny after executives leave.
Typical cost and structure (U.S. market):
- ERPs for private companies commonly range from 100%–300% of the expiring annual premium, depending on period length (single year vs. perpetual tail), industry, and claim profile. For public company perpetual tails, costs can be substantially higher and sometimes unavailable. These market ranges are supported by industry commentary from brokers and insurer market updates. See Marsh and Insurance Information Institute for market context.
- For small private companies whose D&O primary premiums often fall between $5,000–$25,000 annually, a 2–3 year tail could be $10k–$50k. For mid‑market firms (annual premiums $50k–$250k), expect tail costs in the tens to hundreds of thousands.
Key negotiation tips:
- Buy a multi‑year ERP if you expect multi‑year claim emergence.
- For sellers in M&A, negotiate buyer‑paid run‑off or purchase a seller’s run‑off when the purchase agreement doesn’t sufficiently protect former directors.
- Compare quotes from major brokers: Aon, Marsh, and Willis Towers Watson can often access broader market capacity.
When to add Side C / Entity Coverage Endorsements
Side C (entity) coverage protects the company itself for its own liability (e.g., securities class actions that name the corporation). Whether to add it depends on corporate form, capitalization, and likelihood of third‑party claims.
When to consider Side C in the U.S.:
- Private companies anticipating financing or IPO activity (California, New York): Lenders, VCs and underwriters scrutinize entity exposure. Adding Side C can be essential during fundraising or pre‑IPO to close coverage gaps.
- Companies with significant securities exposure: If convertible debt, secondary offerings, or large equity holder concentrations exist, entity exposure increases.
- Entity defense costs in shareholder suits: If the company expects to be a named defendant and has limited indemnification capacity (e.g., regulated entities), Side C is valuable.
- Regulated industries (financial services in New York; healthcare in California): Entity suits or regulatory enforcement can target the corporation as well as individuals.
Cost and marketability:
- For private companies, adding Side C may increase premium by 20%–50% depending on limits and underwriting. For public companies, Side C is often excluded or heavily restricted; when available, it can be materially more costly and subject to higher retentions.
- Example insurers: Chubb and Travelers routinely include options for entity coverage on private company D&O placements; Hiscox offers D&O packages for small businesses where entity coverage options are handled on a case‑by‑case basis.
Practical example:
- A Bay Area software company (Series C, $40M raise) might pay an incremental premium to add Side C to obtain VC investor comfort and to meet lender covenants. Without it, investor negotiation may require indemnities or escrowed funds.
How to decide between Run‑off and Side C (or both)
Use this decision checklist:
- Is the company being sold or ceasing operations? → Prioritize run‑off.
- Will the company remain a legal entity with ongoing operations? → Consider Side C if entity exposure exists.
- Are directors being indemnified after departure? → If indemnity risk exists, Side A + run‑off is essential.
- Is the company public or private? → Public companies face higher cost and restrictions for Side C.
Comparison table
| Endorsement | Primary Purpose | Typical U.S. Use Cases | Typical Cost (U.S. market ranges) | Best for |
|---|---|---|---|---|
| Run‑off / ERP | Extend reporting period after policy termination | M&A sellers, wind‑downs, bankruptcies | 100%–300% of expiring premium for multi‑year ERP (varies) | Sellers, insolvent companies, departing boards |
| Side C / Entity | Cover company for entity claims | Private companies, pre‑IPO, regulated industries | +20%–50% on premium for private placements; higher or restricted for public cos. | Companies needing entity protection (VCs/lenders) |
| Side A enhancement | Protect individuals when company can’t indemnify | High personal exposure situations | Varies; often negotiated language not large premium | Directors, officers in distressed entities |
Location‑specific considerations (NY, CA, TX)
- New York: High plaintiff activity and robust securities case law — run‑off and Side C considerations for public and private firms are critical. Counsel and insurers in NYC often require broader ERPs for M&A sellers.
- California (San Francisco / Silicon Valley): Venture financings and IPO pipelines drive demand for Side C and enhanced Side A. Insurers (Hiscox, Chubb) commonly underwrite tech risks and offer packaged solutions.
- Texas (Houston / Dallas): Energy and private equity deals prompt demand for run‑off in restructuring or bankruptcy. Insurer appetite varies with commodity price cycles.
Pricing examples and insurers
- Hiscox USA markets small‑business D&O with competitive entry points; small private companies may obtain primary D&O policies with premiums starting in the low thousands annually (Hiscox public product pages). See Hiscox D&O offerings for sample pricing.
- Chubb and Travelers are major D&O carriers in the U.S. market, underwriting mid‑market to large placements and offering endorsements for run‑off and Side C (contact brokers Marsh or Aon for live market pricing).
- Brokers Aon and Marsh publish periodic market updates and can place complex run‑off/perpetual tails. Typical mid‑market quote examples (illustrative): a mid‑market company with an expiring premium of $75,000 could face a two‑year ERP quote of $150k–$225k, depending on exposures and limit structure (broker market guidance).

Practical steps to implement
- Run an exposure audit: Identify change events (M&A, insolvency, IPO, regulator contact).
- Engage your broker early: For NY/CA/TX placements, give brokers 30–60 days for market sourcing. Aon and Marsh regularly compete for run‑off placements.
- Obtain multiple ERP quotes: Compare single‑year versus multi‑year and perpetual tail options.
- Negotiate policy wording: Focus on preserved limits, defense inside/outside limits, and continuity of coverage — see negotiation guidance in Negotiation Tips: Getting Favorable Wording for High‑Value Endorsements in Directors and Officers (D&O) Liability Insurance.
- Review related endorsements: Tie in Side A enhancements, regulatory extensions, and broad form endorsements where appropriate — learn more in Top Endorsements That Matter in Directors and Officers (D&O) Liability Insurance and When to Request Them and Cost vs Benefit: Deciding Which Directors and Officers (D&O) Liability Insurance Endorsements Are Worth the Premium.
Bottom line
- Buy run‑off when the company or insureds are leaving operations or when indemnity will no longer be reliable (M&A seller, liquidation, bankruptcy).
- Add Side C / entity coverage when the company itself faces material securities or third‑party liability and indemnification/financial capacity is limited (pre‑IPO, VC/lender requirements, regulated industries).
- Engage brokers early, get multiple ERP and Side C quotes, and negotiate wording — the difference in claim outcomes is material and often far more expensive than the incremental premium for the right endorsement.
