Private equity and venture capital firms will have to conduct their business differently in China in 2014, after regulators overhauled initial public offering rules.

Chinese PE and VC companies used to evaluate the companies by the standards of the China Securities Regulatory Commission for quicker IPOs, but now the market will play a more important role, said Peter Fuhrman, chairman, founder and chief executive officer at China First Capital.

"Under the new IPO system, the share pricing of an IPO company is decided by its strength and competitiveness, so investors will choose companies with real potential to invest in and provide them with the resources of strategy, management and market development to make their own return the best," said Fuhrman.

Private equity and venture capital firms will not find it easy to earn money any more after the new share-listing reform plan is carried out, because even if the companies they invested in get listed, they will still face the risk of losses, said Jin Haitao, chairman of leading Chinese equity investment firm Shenzhen Capital Group Co Ltd.

Jin said PE and VC institutions should cultivate real investment capabilities including those in value-discovery and negotiating. Pre-IPO deals cannot be guaranteed to earn money any more.

A total of 83 Chinese companies completed the examination and received approval from the China Securities Regulatory Commission. About 50 are expected to have finished all IPO procedures and be listed before the end of January. More than 760 companies are in line for approval. It will take about a year to audit all the applications.

In the IPO reform plan announced at the end of November, information disclosure has become more important and the China Securities Regulatory Commission will only be responsible for examining applicants' qualifications, leaving investors and the markets to make their own judgments about a company's value and the risks of buying its shares.

More and more Chinese companies applying for IPOs asked for cooperation with multinational accounting institutions, according to Hoffman Cheong, an assurance leader at Ernst & Young China North Region.

Cheong said the information disclosed can be different after the IPO reform plan is carried out.

According to the IPO reform plan, so long as an issuer's prospectus is received by the commission, it will be released on the commission's website. The company should buy back shares if there is a false statement or major omission. Also it should compensate investors if they lose money in certain situations.
