Established in 2012, we are the first shipyard-affiliated leasing company in Greater China and one of the world's leading ship leasing companies. As a leading market player in the global ship leasing industry, we offer customised ship leasing solutions that suit our customers' different needs. According to the F&S Report, in terms of revenue in 2018, we ranked fourth in the global ship leasing industry with a market share of 3.9% and first in the global non-bank ship leasing industry with a market share of 14.8%.
Our core business is the provision of leasing services, which include finance lease and operating lease. Leveraging our strong expertise in the marine industry, our leasing services primarily focus on ship leasing. We also provide shipbroking and loan services to our customers.
We have a diversified, modern and young vessel fleet. As at 31 December 2018, we owned a total of 65 vessels, including 43 vessels under finance lease arrangements and 22 vessels under operating lease arrangements, with an average age of approximately two years. Our vessel fleet as at 31 December 2018 comprised 25 bulk carriers, 14 tankers, 10 container vessels, 7 marine LNG/LPG units and 9 special tonnage carriers. Leveraging our unique insights into the marine industry, we carefully allocate, adjust and optimise the proportion of various types of vessels based on industry conditions and our customers' needs.
We have a comprehensive and effective risk management system that covers various types of risks involved in our business operations. For example, we have implemented risk management procedures at every major stage of our business operations, from due diligence, project assessment and approval, contract execution, release of funds to lease management. In addition, our five-category asset quality classification system, which was established with reference to the Guidelines of Asset Risk Classification for Non-bank Financial Institutions (非銀行金融機構資產風險分類指導原則) published by the CBRC, allows us to effectively evaluate the quality of our asset portfolio. We believe that such initiatives have allowed us to closely monitor our overall risk profile, promptly identify the risks involved in our daily operations and take appropriate risk mitigation measures.
