Boeing and Tokyo-based Japan Investment Adviser finalized an order for 10 Boeing 737 MAX 8s airplanes valued at $1.12 billion at current list prices.

The order was previously announced as a commitment at the 2017 Paris Air Show in June.

The new 737 MAX 8s are the first directly purchased airplanes for JIA and will help bolster the lessor’s growing fleet of next-generation aircraft.

“We are excited to introduce the new 737 MAX 8 airplane into our single-aisle fleet and we are confident that this airplane will diversify our operating lease portfolio in the years ahead,” said Naoto Shiraiwa, president and CEO of JIA. “The 737 MAX will provide us with a stronger competitive advantage in providing our future airline clients with reliable airplanes that make sense economically.”

JIA is a financial solutions provider and is listed on the Tokyo Stock Exchange. Its group activities include operating a lease business that manages a fleet of around 60 aircraft worldwide through its operating lease arm, JP Lease Products & Services (JLPS). The current managed fleet includes Next Generation Boeing 737s as well as Boeing 777s.

“We are honored to play an important role in the growth of JIA as a key player in the commercial leasing business within Asia,” said Ihssane Mounir, senior vice president of Global Sales and Marketing, Boeing Commercial Airplanes. “JIA has made the perfect selection for their new fleet strategy, as the 737 MAX provides operators with market-leading economics and reliability. We are proud to share this milestone with JIA as we continue to strengthen our partnership going forward.”
