Challenger’s core business is selling annuity products in the Australian retirement market and, since November 2016, selling Australian dollar-denominated annuities into Japan's large retirement market. The firm’s annuity products provide investors guaranteed regular payments over an agreed term for an upfront lump sum investment and is designed primarily to protect investors from the longevity risk of outliving their savings. Challenger also operates a funds management business, Fidante Partners, which has minority stakes in several boutique global investment managers, and Challenger Investment Management, which primarily manages investments supporting its annuities business.
