Investors in the Cornerstone Core Properties REIT Inc. were recently told by the company that the shares, once valued at $8, are now worth $2.25 (see article in InvestmentNews by Bruce Kelly). The article references a letter from the REIT’s chairman and chief executive Terry Roussel, as saying “The estimated per-share value has been adversely affected by the recent global economic downturn, negatively impacting our small business tenant base, which has resulted in approximately $43 million of previously announced impairment charges recorded in the second and third quarters of 2011.”
