We generally do not offer renewal terms or purchase options in our leases, although certain of our operating leases allow the lessee the option to extend the lease for an additional term. Operating leases with fixed rentals and step rentals are recognized on a straight-line basis over the term of the initial lease, assuming no renewals. Operating lease rentals that adjust based on a London Interbank Offered Rate (“LIBOR”) index are recognized on a straight-line basis over the lease term using the prevailing rate at lease commencement. Changes to rate-based lease rentals are recognized in the statements of income (loss) in the period of change.</span></div><div style="margin-bottom:9pt;margin-top:9pt;text-align:justify;text-indent:24.75pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10.5pt;font-weight:400;line-height:120%">In certain instances, we may provide lease concessions to customers, generally in the form of lease rental deferrals.

As a result of COVID-19, there has been a dramatic slowdown in air traffic, with many markets in near complete shutdown. According to the International Air Transport Association (“IATA”), as of November 2020, air travel was down to approximately 34% of normal levels and a full recovery to pre-pandemic levels is not expected for several years. Substantially all the world’s airlines are experiencing financial difficulties and liquidity challenges. While we believe the long-term demand for air travel will return to historical trends over time, the near-term impacts of the COVID-19 virus’ economic shock are material; the extent and duration of which cannot currently be determined.</span></div><div style="margin-bottom:9pt;margin-top:9pt;text-align:justify;text-indent:24.75pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10.5pt;font-weight:400;line-height:120%">Airlines have been seeking to preserve liquidity through a combination of requesting government support, raising debt and equity, delaying or canceling new aircraft orders, furloughing employees, as well as requesting deferrals from lessors. We have agreed to defer near-term lease payments with certain of our airline customers, which they are obliged to repay over time. As of January 8, 2021, we have agreed to defer approximately $101,000 in near-term lease payments, including $76,460 that appear in our Consolidated Balance Sheets as components of Accounts receivable, Net investment in leases, or Other assets as of November 30, 2020. This represents approximately 15% of Lease rental and Direct financing and sales-type lease revenues for the twelve months ended November 30, 2020. Deferrals have been agreed to with 37 airlines, representing 46% of our customer base, and for an average deferral of five months of lease rentals.
