🔗 '''Facultative obligatory treaty (fac-ob)''' is a hybrid [[Definition:Reinsurance | reinsurance]] arrangement that grants the [[Definition:Cedent | cedent]] the option — but not the obligation — to cede individual risks into the treaty, while the [[Definition:Reinsurer | reinsurer]] is obligated to accept any risk the cedent chooses to cede, provided it falls within the treaty's defined terms. This structure sits between a pure [[Definition:Facultative placement | facultative placement]] (where both sides negotiate each risk individually) and a standard [[Definition:Treaty reinsurance | obligatory treaty]] (where all qualifying risks are automatically ceded and accepted). The fac-ob gives the cedent significant flexibility and strategic control over which risks it retains versus which it passes to reinsurers.

⚙️ Under a fac-ob treaty, the contract specifies parameters such as eligible lines of business, classes of risk, geographic scope, maximum cession limits, and [[Definition:Premium | pricing]] terms. The cedent's [[Definition:Underwriter | underwriters]] then evaluate each risk as it comes through the door and decide whether to cede it into the fac-ob or retain it on the company's net account (or place it into other reinsurance arrangements). Once the cedent declares a risk into the treaty, the reinsurer must accept its share — there is no case-by-case right of refusal. This asymmetry creates an inherent [[Definition:Adverse selection | adverse selection]] concern for reinsurers, who may fear that cedents will cede only their least desirable risks. To mitigate this, reinsurers typically impose tighter underwriting guidelines, require detailed [[Definition:Bordereaux | bordereaux]] reporting, and may include aggregate caps or event limits within the treaty. In the [[Definition:Lloyd's of London | Lloyd's]] market, fac-ob treaties are used by [[Definition:Syndicate | syndicates]] and [[Definition:Coverholder | coverholders]] seeking flexibility in specialty lines such as [[Definition:Marine insurance | marine]], [[Definition:Energy insurance | energy]], and [[Definition:Property insurance | property]].

⚠️ The fac-ob structure occupies an important niche precisely because it addresses situations where neither pure facultative nor pure treaty reinsurance is ideal. A cedent writing a heterogeneous book — perhaps a mix of standard and non-standard property risks across multiple regions — may find that a standard treaty either imposes too rigid a cession requirement or fails to accommodate unusual exposures. The fac-ob lets the cedent cherry-pick which risks benefit most from reinsurance support while keeping attractive risks net. However, the adverse selection dynamic means reinsurers price fac-ob treaties with a premium over comparable obligatory covers, and the availability of fac-ob capacity tends to tighten during hard [[Definition:Reinsurance market cycle | market cycles]] when reinsurers are more cautious about open-ended commitments. Cedents that manage their fac-ob relationships transparently — sharing data, maintaining consistent cession quality — tend to secure more favorable long-term terms.
