CurtCo Media may fetch $500 million in upcoming sale.

Malibu-based CurtCo Media Labs LLC, publisher of super-luxury titles, is looking to cash in on the high-end market that it serves by putting its catalog of titles up for sale.

Goldman Sachs LLC will manage the auction and provide financing to buyers, and the sale could fetch more than $500 million, according to recent reports.

Founded by Bill Curtis in 2001, CurtCo's publications target what Curtis calls the "recession-proof' market--the less than 1 million American families that have a net worth of $5 millionplus, own multiple luxury homes, and have extravagant yachts and car collections.

In addition to its flagship publication the Robb Report, the company owns 15 "ultra-luxury" titles, including Worth, San Diego Magazine, Showboats International and Home Entertainment.

CurtCo Media has grown its revenue from about $20 million to $100 million over the last four years. In 2003, the company secured $100 million in acquisition capital from private equity firms Weston Presidio and TD Capital.

The company last month purchased Art'& Antiques, a 105,000-circulation magazine, for a reported $7 million. The Robb Report Luxury Resorts will hit newsstands this month.
