The US directors and officers liability (D&O) insurance market is the largest D&O insurance market in the world by premium volume, driven by US federal securities class action litigation, shareholder derivative actions, merger-objection cases, and bankruptcy-related claims. It is dominated by US domestic carriers in the primary and lower excess layers, with Bermuda and London market participation in the upper excess.

The US D&O market provides liability cover to corporate directors, officers and (in many policy forms) the entity itself for claims arising from breach of duty in their capacity as directors or officers. The product is structured in three “sides”: Side A (cover for individual directors when the company cannot indemnify them); Side B (reimbursement of the company when it does indemnify); Side C (cover for the entity for securities claims, principally Section 11/12 Securities Act claims and Section 10(b) Exchange Act claims). Side A-only excess Difference In Conditions (DIC) towers are widely placed to provide ring-fenced protection for individuals.
The substantive D&O exposure derives principally from federal securities law: Securities Act 1933 sections 11 and 12; Securities Exchange Act 1934 section 10(b) and Rule 10b-5; the Private Securities Litigation Reform Act 1995 (PSLRA); Sarbanes-Oxley Act 2002; Dodd-Frank Act 2010. State law fiduciary duty actions (notably Delaware Chancery cases under the General Corporation Law of Delaware) supplement the federal regime. The market is supervised by the various state insurance regulators; New York and California are particularly important domiciles.
Total US D&O premium has fluctuated between $5bn and $20bn in recent decades, with significant cyclicality. The market hardened materially from 2019 to 2022 in response to: rising securities class action frequency; the COVID-19 securities litigation surge; bankruptcy claims; and SPAC-related litigation. Subsequent softening from 2023 saw rates ease, particularly for publicly listed companies with strong claims experience.
Capacity is provided by US domestic carriers (Chubb, AIG, Travelers, Hartford), Bermuda excess writers (Arch, AXIS, Allied World, Endurance/Sompo), and London market subscribers including Lloyd’s. Typical primary policy limits are $10m-$25m; total tower capacity for Fortune 500 companies frequently exceeds $200m.
The US D&O market is significantly larger and more litigious than the UK market — the absence of securities class action lawyering, the higher cost of US discovery, and the existence of the contingency-fee plaintiff bar create a different risk landscape. UK-listed companies with US securities listing or US operations frequently buy US-specific D&O cover layered over UK Side A protection.
A NYSE-listed mid-cap technology company purchasing a D&O programme: $100m total tower comprising $25m primary from Chubb at $1.2m premium, $25m first excess from AIG, $50m of further excess capacity from Bermuda and London market subscribers, with a separate $50m Side A DIC tower for individual directors only. Annual total premium approximately $5-7m.
