📋 '''Years of account''' is a foundational accounting concept within the [[Definition:Lloyd's of London | Lloyd's of London]] market, under which each [[Definition:Lloyd's syndicate | syndicate]] segments its business into discrete annual cohorts — typically remaining open for three years before being closed by [[Definition:Reinsurance to close (RITC) | reinsurance to close (RITC)]]. Every [[Definition:Insurance policy | policy]] bound by a syndicate is allocated to the year of account in which the risk incepts, and all [[Definition:Premium | premiums]], [[Definition:Claim | claims]], and expenses associated with that policy are tracked within that cohort throughout its life. This approach differs sharply from the calendar-year or accident-year accounting models used by most conventional [[Definition:Insurance carrier | insurers]] worldwide, and it gives Lloyd's participants a uniquely granular view of profitability vintage by vintage.

⚙️ A year of account typically opens on January 1 and runs for a development period of approximately 36 months, during which the syndicate collects premiums, pays claims, and sets [[Definition:Loss reserve | reserves]] for that cohort. At the end of the third year — or later if the year remains "open" due to unresolved [[Definition:Outstanding claims | outstanding claims]] or [[Definition:Incurred but not reported (IBNR) | IBNR]] uncertainty — the syndicate's [[Definition:Managing agent | managing agent]] arranges an RITC transaction. Through RITC, all remaining [[Definition:Underwriting | underwriting]] liabilities from the closing year are transferred to a successor year of account (usually the following year's cohort within the same syndicate), accompanied by a corresponding transfer of assets to cover those liabilities. The price of RITC is negotiated and represents an actuarial estimate of the ultimate cost of outstanding obligations. If uncertainty is too high or the liabilities are too volatile to price with confidence, the managing agent may leave the year of account open, which delays profit distribution to [[Definition:Lloyd's name | Names]] or corporate [[Definition:Capital provider | capital providers]].

💡 The years-of-account system gives Lloyd's a distinctive mechanism for enforcing underwriting discipline and transparency. Because each annual cohort must eventually stand on its own financial merits before closing, syndicates and their capital backers can pinpoint exactly which underwriting vintage generated profits or losses — a level of attribution that calendar-year accounts can obscure through reserve releases and development from prior periods. This structure also affects how [[Definition:Capital requirement | capital requirements]] are calculated at Lloyd's: the [[Definition:Society of Lloyd's | Society of Lloyd's]] and the [[Definition:Prudential Regulation Authority (PRA) | Prudential Regulation Authority (PRA)]] assess solvency with reference to each syndicate's open years. Outside Lloyd's, the concept has no direct parallel in most markets, although the principle of cohort-based underwriting analysis influences how sophisticated reinsurers and [[Definition:Insurance-linked securities (ILS) | ILS]] structures track performance by inception year.
