[1]  1The increase in the number of projects from December 31, 2010 to June 30, 2011 is due to the reclassification of two projects from property and equipment to real estate held for development and sale. The reclassifications were due to a change in business plans for the projects in connection with our Enterprise Improvement Plan.
