truck leasing company, Metropolitan Distributors, including a fleet of 4,000 trucks. This acquisition increased The Hertz Corporation's fleet to 15,500 trucks and 12,900 passenger cars. During the General Motors ownership, the company had sold many local Hertz franchises to independent business entities. With the financial backing of investment bankers Lehman Brothers, led by Lehman partner and Hertz director, Frank J. Manheim, Hertz began a buyback program for the franchises in the US, then expanded globally. Manheim predicted the global growth and devised the strategy which made “Hertz” a household name and led to dynamic growth in the company's market capitalization from $7 million in 1953 to $100 million in 1965. The company expanded to South America in 1961. In 1967, The Hertz Corporation became a subsidiary of Radio Corporation of America. In 1985, the car rental company was sold to UAL Corporation, later known as Allegis Corporation, for a cash deal of US$587.5 million. This acquisition expanded Hertz's vehicle renting and leasing, with nearly 400,000 cars and trucks in 120 countries across the globe. In the summer of 1987, Allegis Corporation chairman and president Frank A. Olson announced the company would be selling Hertz due to internal changes. Park Ridge Corporation, which was owned and operated under Ford Motor Company, purchased Hertz in October 1987 for US$1.3 billion, and Hertz relocated its headquarters from Midtown Manhattan to Park Ridge, New Jersey in 1988. In 2002, Hertz became the first international car rental company to open in China. In 2013, Hertz began partnering with China's largest car rental company, China Auto Rental. In 2016, it reduced its ownership stake but announced a continuing commercial relationship through 2023. By the second quarter of 2005, Hertz produced about ten percent of Ford's overall pre-tax profit. However, after 18 years of ownership, the Ford Motor Company announced it would be selling the Hertz brand with the intent to focus more on building Ford cars and trucks. Private equity firms Clayton, Dubilier & Rice, The Carlyle Group, and Merrill Lynch Global Private Equity agreed to purchase all shares of common stock in Hertz for an estimated US$15 billion, including debt, and the business itself for US$5.6 billion in 2005. The Clayton, Dubilier & Rice consortium took Hertz Global Holdings public again on the New York Stock Exchange in November 2006, and Hertz began to expand through Europe. Hertz launched subbrand "Simply Wheelz" in September 2007
