Here are the main life insurers in Sri Lanka that offer participating / “with‑profits” policies (i.e., policies that can receive annual bonuses or policyholder dividends). I’ve listed each insurer with a short note and a supporting source.

• Union Assurance PLC — publishes and advertises universal-life / participating policyholder dividend rates (recent declarations reported). (ceo.lk)
• Ceylinco Life Insurance Limited — offers traditional participating (reversionary/bonus) life plans (product pages show illustrated bonus assumptions). (ceylincolife.com)
• Sri Lanka Insurance Corporation / Sri Lanka Insurance (Life) — state-owned life insurer; regularly declares bonuses / annual policyholder payouts. (srilankabiz.lk)
• Softlogic Life Insurance PLC — sells endowment/participating plans that pay annual bonuses and loyalty bonuses. (softlogiclife.lk)
• HNB Assurance PLC — offers participating child/endowment plans with declared annual bonuses (product pages describe “declared annual bonus” mechanics). (hnbassurance.com)
• Janashakthi Insurance PLC (life business) — a long‑established local insurer that issues participating life products (company materials and market listings). (aibl.lk)
• AIA Insurance Lanka Limited — a major life insurer in Sri Lanka that historically offers participating (traditional) savings/with‑profits products. (dailymirror.lk)
• Other licensed life insurers (many also have participating products): Amana Takaful Life PLC, LOLC Life, SANASA Life, Asian Alliance / Allianz (where applicable), Continental Life, etc. (complete list of life insurers appears on industry/broker pages and IRCSL publications). (aibl.lk)

Notes and next steps

• “Participating” / “with‑profits” life policies are common across Sri Lanka’s life insurers, but not every product from each insurer participates — you must check the specific product brochure (many product pages explicitly state “reversionary bonuses”, “declared annual bonus”, “policyholder dividend rate”, or give illustrated maturity values at assumed dividend rates). (softlogiclife.lk)
• If you want: I can (a) pull the most recent declared dividend/bonus rates for a particular insurer (e.g., Union Assurance, Ceylinco, SLIC, Softlogic, HNB) for a specific year, or (b) provide contact/website links and the product names that are participating for each insurer. Tell me which option you prefer and which insurers (or years) to check.
