LeaseAccelerator released its Who is Most Impacted by the New Lease Accounting Standards report, a ranking of the U.S. public companies with the largest leasing obligations. The report includes total operating lease obligations for the 1,000 largest U.S. public companies sourced from Fortune’s 2018 Fortune 1000 report.

Starting in January 2019, the new lease accounting standards will begin to take effect, requiring U.S. public companies to transfer an estimated $3 trillion of operating leases onto corporate balance sheets as right-of-use assets and corresponding lease liabilities. Historically, only a limited set of information about operating leases has been reported in the footnotes of SEC filings. However, under the new ASC 842 and IFRS 16 standards, companies will be required to add new line items to the balance sheet for these operating leases. As a result, key financial metrics, such as return on assets, asset turnover and the quick ratio will be impacted by these accounting changes.

Collectively, the top 1,000 public companies in the U.S. add up to $983 billion in operating lease liabilities. Although companies in every industry use leasing, there is a particularly high concentration of leases in the retail, airlines and telecommunications sectors. The retail industry will experience the greatest proportional balance sheet change from the new standards as specialty, grocery and food service chains tend to lease many of their brick and mortar store locations.

“With less than six months remaining until the initial deadlines for the new lease accounting standards, CFOs need to start developing strategies for communicating these balance sheet changes to their investor communities,” said Michael Keeler, CEO of LeaseAccelerator. “We hope that this report will help companies understand and compare the level of impact they will experience from ASC 842 relative to their peer group.”
