In November 2017, the IASB (International Financial Reporting Standards) sets out a new rule for the recognition and measurement of the lease. This is the IFRS 16, replacing the old IAS 17. The new standard removes the lessee’s distinction between operating and financial lease and it will have a substantial impact on companies that have previously kept a large proportion of their financing off balance sheets. At the same time, the FASB announced the new ASC Topic 842, replacing the old ASC Topic 840 for the same reasons. Under IAS 17 companies have exploited a financial accounting loophole by structuring lease transactions as operating leases, favoring opportunistic behaviors by managers and distorting the investors' perception of the disclosure. IFRS 16 removes the so-called bright lines companies used to avoid capitalization of leases and turns any attempt to hide lease liabilities off the balance sheet into a futile exercise to improve the transparency of information. So with the introduction of the new principles IFRS 16 and ASC Topic 842, the balance sheets will provide a more faithful representation of leases. According to an appreciation, in leasing contracts, world companies have about USD 3.3 trillion on their balance sheets (the main sectors covered by this alternative form of financing have always been the air transport, retail, and logistics industries). In these sectors, another advantage of IFRS 16 and ASC Topic 842, is also better management of company resources, which increase the concept of “supply chain management”, so helping managers to make better decisions in the aim of the firms.
