The new standard, in addition to bringing substantial new assets and liabilities onto airlines' balance sheets, will have an impact on reported profit and performance measures such as return on capital employed (ROCE). Perhaps most significantly the impact on individual airlines will depend on their particular financing and leasing structures and may be very different from the impact on their peers.
Airlines will need to assess early the impact on their results, and if possible on that of their peers, and to develop a plan for explaining this to their shareholders and other stakeholders.
