Hogg Robinson Group next month will launch a public offering on the London Stock Exchange

, according to published reports. HRG intends to raise £190 million ($362 million) and achieve a market value of £600 to £700 million ($1.1 to $1.3 billion), the reports said. The company would use the funds partly to refinance some debt and pay into its benefits plan; HRG also is actively seeking acquisitions in the United States and elsewhere. The company's shares were traded publicly until 2000, when private equity group Permira bought most of HRG.
