On 3 April, IAG announced that British Airways had finalised its new pension scheme. The airline closed its New Airways Pension Scheme (NAPS) to future accrual and its British Airways Retirement Plan (BARP) to future contributions from March 31, 2018. The schemes have been replaced by a flexible benefits scheme, incorporating a new defined contribution pension scheme, called the British Airways Pension Plan (BAPP). NAPS active members were offered a choice of transition arrangements. In Q1 2018, the net impact of these arrangements, the liability reduction resulting from the closure of NAPS and the cost of closing BARP will be treated as an exceptional gain of £598 million. The annual costs for BAPP are expected to be approximately £80 million lower than the equivalent NAPS and BARP costs in 2017.
