HHI: The common abbreviation for the Herfindahl-Hirshman index (or the Herfindahl index), which is a measure of concentration of the production in an industry that's calculated as the sum of the squares of market shares for each firm. This is an alternative method of summarizing the degree to which an industry is oligopolistic and the relative concentration of market power held by the largest firms in the industry. The Herfindahl index gives a better indication of the relative market control of the largest firms than can be found with the four-firm and eight-firm concentration ratios.

COMPTROLLER OF THE CURRENCY

An agency of the U.S. Federal government responsible for chartering national banks. In other words, anyone wanting to establish a bank with the word "national" in the title must gain permission from the Office of the Comptroller of the Currency (OCC). The Comptroller is also responsible for regulating banks and might even assume control of a bank that is in serious trouble (that is, on the verge of failure). Although the term "currency" appears in the title, the Office of the Comptroller of the Currency is primarily a bank regulator and has almost nothing to do with the nation's "currency." The OCC was established in 1863 as a bureau of the U.S. Department of the Treasury and is located in Washington, D.C.

"You need just the right amount of ambition . . . If you have too little ambition, you don't push or work hard. If you have too much ambition, you put yourself ahead of others, elbow them out of your way. "
