Japanese leveraged lease: A JLL requires the establishment of a special purpose company to acquire the aircraft, and at least 20% of the equity in the company must be held by Japanese nationals. Widebody aircraft are leased for 12 years, while narrowbody aircraft are leased for 10 years. Under a JLL, the airline receives tax deductions in its home country, and the Japanese investors are exempt from taxation on their investment. JLLs were encouraged in the early 1990s as a form of re-exporting currency generated by Japan's trade surplus
