Huawei, China’s largest maker of telecommunications equipment, has investigated 116 employees and sent four of them to court over allegations of graft in its consumer and corporate units, reports have said. The staffers are suspected of taking bribes in China, Caixin and China Business News , two mainland media outlets, reported. The graft occurred in the company’s enterprise and consumer units, the reports said. The employees reportedly sold Huawei products and services at a discount in exchange for kickbacks from clients. Most of the investigated employees brazenly asked distributors for such bribes: 53 out of 69 distributors paid bribes after these were solicited by the Huawei staffers, the Caixin report said. Huawei has clear policies on acceptable business practices, a company spokesman told the South China Morning Post . “We take a zero tolerance approach to any form of employee practice that fails to meet the standards we set for ourselves,” he said. Both reports said the number of staffers implicated was dated as of August 16. The company did not say whether more employees have been investigated since. In a recent interview , Ren Zhengfei, the company’s founder, called internal graft a challenge bigger than any competitor. “The only thing that can stop us is internal graft,” he reportedly said. Richard Yu Chengdong, CEO of Huawei Consumer Business Group, wrote in a leaked internal e-mail to staffers in July that the staffers accepting bribes had been identified. “I and many of Huawei’s executives have worked our way up from the grass roots,” he wrote. “Today, we don’t worry about clothes and food, and enjoy the happiness and freedom of work. This proves that Huawei’s distribution mechanism is fair.” “Momentary greed [only brings] unease, ill-gotten gains can’t be hidden […] and will lead to jail time and the loss of freedom,” he wrote. The Shenzhen-based company overtook Lenovo and LG in the second quarter of 2014 to become the world’s third-largest maker of smartphones, according to data by International Data Corporatio n , a research company. Huawei accounted for 6.7 per cent of global smartphone shipments in the second quarter this year, it said. The company’s consumer business unit accounted for 23.8 per cent of its 239 billion yuan (HK$301 billion) in revenue last year, according to its annual report . It grew 17.8 per cent, twice as much as overall revenue of the telecom equipment giant. Its enterprise business unit, which caters directly to corporate clients, accounted for 6.4 per cent of annual revenue last year. The unit’s revenue grew 32.4 per cent in 2013.
