service provider controlled by cosmetics heir Ronald S. Lauder, plans to raise funds for acquisitions in a $150 million initial public offering.

The Bermuda-based company didn't say how many or at what price it expects to sell Class A common shares in the IPO. It based its filing fee on an estimated value for the total offering of $150 million, according to an S-1 registration statement filed with the Securities and Exchange Commission yesterday.

RSL focuses on providing international voice phone services for small and medium-sized businesses, with revenue-producing operations in the US, Australia, United Kingdom, France, Germany, Sweden, Finland, the Netherlands and Denmark. The telecommunications provider, founded by Lauder and company president Itzhak Fisher in 1994, plans to begin operations in Italy, Austria, Venezuela, Japan and Portugal, the filing said.
