We are a long-established general contractor and subcontractor in Hong Kong, mainly engaged in providing (i) building construction services; (ii) alteration, addition, decoration works and building services; and (iii) maintenance and restoration of historic buildings. During the track record period, we undertook 14, 26 and 4 large-scale building construction services, alterations, additions, renovation works and building services, as well as the maintenance and restoration of historic buildings, respectively, with a contract value of over HK$3 million. As of the last practical date, we have 10, 12 and 22 large-scale projects under construction (in progress or not yet under construction) in building construction services, remodeling, addition, renovation works, and building services and maintenance and restoration of historic buildings, respectively. At the last feasible date, the total revenue of our projects under construction is expected to be confirmed after the track record period of approximately HK$637.3 million, of which the total unsettled project value of approximately HK$360.7 million is expected to be confirmed for the year ended March 31, 2017. We acted as the general contractor and sub-contractor for the track record period until the last viable date. As the general contractor, we carry out the work in accordance with relevant contracts and may assign work to subcontractors under the supervision and management of our project management team. Our role as a general contractor generally includes providing overall project management and supervising the work carried out by subcontractors and/or site workers to ensure that we meet the requirements of the contract, including the quality, safety, environmental protection of the project, and that the project is completed on schedule and within budget. As a subcontractor, we generally work under the supervision of a general contractor and provide assigned services. We generally obtain projects through a tender process. For public clients, we generally identify potential projects through (i) receiving invitations to tender; and (ii) reviewing tender invitations published by government departments on various platforms (including the Gazette). In the case of private clients, we are generally invited by the client or agent acting on behalf of the client to submit tenders for the project. During the track record period, our clients included governments, quasi-government organizations, universities, schools, and private companies. In the three years ended March 31, 2016, revenue from the five major customers accounted for approximately [73.4]%, [69.5]% and [65.7]% of total revenue, respectively. We have maintained business relationships with some of our major customers for over five years.
