SINGAPORE - Singapore Exchange (SGX) has mailed out 195 corrected Central Depository (CDP) account statements for May 2015 on Monday, after apologising last week for sending erroneous statements to some customers.

The affected accountholders will be contacted by service officers to address their concerns, SGX said in a news release on Monday.

"SGX customer service officers will be contacting all affected accountholders to directly assist with any questions or concerns they may have," it said.

The exchange last week apologised for the mistake which they said arose from human error in the printing process, and said less than one per cent of some 460,000 statements were affected. The actual figure is 195, SGX confirmed on Monday.

The bungle comes six months after technical glitches caused two lengthy halts in trading on Nov 5 and Dec 3.

The CDP, a subsidiary of SGX, holds shares on behalf of investors. It helps to process and keep records of share transactions for investors.

According to the SGX, there were 71,043 new CDP accounts opened in the past year. More than half of the 1.7 million accounts at CDP have share investments, it said previously.
