China's latest round of initial public offerings has raised more than 30 billion yuan ($4.9 billion) with underwriters accruing 1.5 billion yuan in fees, according to the financial service provider iFinD.

The amount of sponsors' fees increased from 5.6 percent to 7.25 percent, hitting a record high, 21st Century Business Herald reported on Wednesday.

Forty-five companies have gone public on the A-share market since China Securities Regulatory Commission announced a resumption of IPOs at the end of last year, raising 30.1 billion yuan.

In all, 52 companies have received approvals for IPOs and the CSRC will not review new IPO applications until March, according to Xinhua News Agency.

The IPO resumption comes after a yearlong hiatus in 2012. Deloitte expects around 200 to 230 companies to complete their IPOs on the A-share market this year, raising 150 billion yuan to 170 billion yuan.
