 ENRC annual report released on 30 April said that UK authorities are investigating whether ENRC breached Britain's rules for listed companies, specifically with acquisitions made in the Democratic Republic of Congo and a 2012 sale of railway line repair company Zhol Zhondeushi to a company connected to the family of one of the miner's co-founders.In November 2013 ENRC de-listed from the LSE after the Groups founders gained acceptances from 96.7 percent of shareholders for their offer - of $2.65 in cash and 0.23 of a Kazakhmys share for each one in ENRC - to acquire the company along with the Kazakh government.In February 2014, it was reported that the firm would have to sell its international assets, including its lucrative copper mines in the Democratic Republic of Congo, after the company’s founders came under increased pressure to repay the large loan they had taken out to privatise ENRC.
