Romney soon switched Bain Capital's focus from startups to the relatively new business of leveraged buyouts: buying existing companies with money mostly borrowed from banking institutions using the newly bought companies' assets as collateral, then taking steps to improve the companies' value, and finally selling those companies once their value peaked, usually within a few years. Bain Capital lost money in many of its early leveraged buyouts, but then found deals that made large returns. The firm invested in or acquired Accuride Corporation, Brookstone, Domino's Pizza, Sealy Corporation, Sports Authority, and Artisan Entertainment, as well as some lesser-known companies in the industrial and medical sectors. Much of the firm's profit was earned from a relatively small number of deals; Bain Capital's overall success-to-failure ratio was about even.
