Shares of Australian software and computer services firm Computer Power Group Pty Ltd rose sharply after it announced the sale of its US and UK businesses for the equivalent of about $71m cash. Buyer is Interim Services Inc of Fort Lauderdale, Florida. The Melbourne company wants to refocus its business on the Asia-Pacific region, but still has a small international CP Software operation. The units sold provide flexible staffing and consulting services in areas including client-server support, network integration, technical communications and systems engineering, covering the gamut from banking and energy to telecommunications and health care. The buy furthers Interim’s diversification into computing begun this year: its main business is supply of temporary staff and home health care.
