<p>Bot: Creating new article from JSON</p> <p><b>New page</b></p><div>👩‍💼 &#039;&#039;&#039;Reserving actuary&#039;&#039;&#039; is a credentialed professional — typically a Fellow of the [[Definition:Casualty Actuarial Society (CAS) | Casualty Actuarial Society]] or equivalent body — who specializes in estimating the [[Definition:Loss reserve | loss reserves]] an insurer must hold to meet its outstanding claim obligations. Unlike [[Definition:Pricing actuary | pricing actuaries]], who look forward to set rates on future business, the reserving actuary looks both backward and forward: analyzing historical [[Definition:Loss triangle | loss development]] data and projecting how existing claims will settle over time. This role sits at the intersection of finance, [[Definition:Underwriting | underwriting]], and claims, making it one of the most strategically influential positions within an insurance organization.<br /> <br /> 🛠️ Day-to-day, the reserving actuary assembles and validates data, selects and applies projection methodologies — such as the [[Definition:Chain-ladder method | chain-ladder]], [[Definition:Bornhuetter-Ferguson method | Bornhuetter-Ferguson]], and frequency-severity approaches — and produces estimates across [[Definition:Line of business | lines of business]] and [[Definition:Accident year | accident years]]. They present findings to management, articulate the key sources of uncertainty, and recommend whether carried reserves should be adjusted. In many jurisdictions, a designated [[Definition:Appointed actuary | appointed actuary]] must sign a formal [[Definition:Actuarial opinion | actuarial opinion]] on the reasonableness of reserves filed with [[Definition:Insurance regulator | regulators]]. Within the [[Definition:Lloyd&#039;s of London | Lloyd&#039;s]] market, reserving actuaries engage directly with Lloyd&#039;s oversight teams, and their sign-off is required for [[Definition:Syndicate | syndicate]] business plans.<br /> <br /> 🌟 The judgment calls a reserving actuary makes ripple across the entire enterprise. Their estimates determine reported earnings, influence [[Definition:Risk-based capital (RBC) | risk-based capital]] adequacy, shape [[Definition:Reinsurance | reinsurance]] purchasing strategies, and drive investor confidence. An actuary who identifies emerging adverse [[Definition:Reserve development | development]] early — say, from rising [[Definition:Social inflation | social inflation]] in casualty lines — enables the company to adjust [[Definition:Pricing | pricing]] and reserves proactively rather than reactively. For [[Definition:Managing general agent (MGA) | MGAs]] and [[Definition:Insurtech | insurtech]] startups, hiring or engaging a reputable reserving actuary signals operational maturity to [[Definition:Insurance carrier | carriers]] providing capacity and to prospective investors during fundraising rounds.<br /> <br /> &#039;&#039;&#039;Related concepts&#039;&#039;&#039;<br /> {{Div col|colwidth=20em}}<br /> * [[Definition:Reserving]]<br /> * [[Definition:Actuarial opinion]]<br /> * [[Definition:Appointed actuary]]<br /> * [[Definition:Loss reserve]]<br /> * [[Definition:Pricing actuary]]<br /> * [[Definition:Reserve adequacy]]<br /> {{Div col end}}</div>
