Alan Tan is the CEO for an airline company. The company has a large proportion of its aircraft leased from manufacturers under lease agreements that can be cancelled at any time with minimal penalties. At the end of the period starting on 1 January 2019, looking at the statement of financial position prepared by the company accountant, Joyce Maine, Alan noticed a large increase in the total assets and liabilities. Not being aware of any major restructuring activities or investments during the period but having heard about a change in the accounting rules governing leases, Alan asks Joyce to make a report describing how the changes in those accounting rules affect the company. Required Joyce approaches you, a junior accountant, to summarise the changes in the treatment of some leases that caused the large increase in the total assets and liabilities. Provide a short description of those changes to Joyce.
