Companies are ordered by straight market capitalization size (in US $), as of November 17, 2008. "Market Capitalization Size" refers to the total dollar market value of all of a company's outstanding shares. Market capitalization is calculated by multiplying a company's shares outstanding by the current market price of one share. The investment community uses this figure to determining a company's size, as opposed to sales or total asset figures.
