The dividends classified as taxable ordinary income are not "qualified dividend income" and, therefore, are not eligible for capital gains rates. Dividend distributions which are declared and recorded during a calendar year and paid within 30 days of the end of the year are included in that year's distributions. Accordingly, the Company's 2011 dividend distributions include the January 5, 2012 payment to holders of Common Stock.
