Huawei claims it is an employee-owned company, but it remains a point of dispute. Ren Zhengfei retains approximately 1 percent of the shares of Huawei's holding company, Huawei Investment & Holding, with the remainder of the shares held by a trade union "committee" (not a trade union per se, and the internal governance procedures of this committee, its members, its leaders or how they are selected all remain undisclosed to the public) that is claimed to be representative of Huawei's employee shareholders. The company's trade union committee is registered with and pay dues to the Shenzhen federation of the All-China Federation of Trade Unions, which is controlled by the Chinese Communist Party. This is also due to a limitation in Chinese law preventing limited liability companies from having more than 50 shareholders. About half of Huawei staff participate in this scheme (foreign employees are not eligible), and hold what the company calls "virtual restricted shares". These shares are non-tradable and are allocated to reward performance. When employees leave Huawei, their shares revert to the company, which compensates them for their holding. Although employee shareholders receive dividends, their shares do not entitle them to any direct influence in management decisions, but enables them to vote for members of the 115-person Representatives’ Commission from a pre-selected list of candidates. The Representatives’ Commission selects Huawei Holding's Board of Directors and Board of Supervisors.
