BOC Aviation's total assets increased to $9.9bn after paying a dividend of $113m to the Bank of China Group. It had $680m in cash and a debt-to-equity of 4:1. It had a fleet of 223 aircraft, including 198 owned and 25 managed aircraft, and more than 50 airline customers.

"In the first 20 years, we have built a strong balance sheet and a pipeline of future orders for the next phase of our growth,'' Robert Martin, CEO of BOC Aviation, said. "We are justifiably proud of our achievements but also mindful we continue to require focus, discipline, management experience and retention of professionals, and robust risk management processes."
