Thank you, Samir. Good morning, and thank you for joining us and for your interest in our company. The fourth quarter of 2011 was another excellent quarter for DDR, but that really should come as no surprise at this point. 2011 and 2010 overall were excellent years for our company as we continue to execute on our articulated strategy designed to enhance all aspects of our business model. We continue to be very consistent performer in very inconsistent times. And we look ahead to 2012, that consistent performance will continue. Fourth quarter 2011 marks 7 consecutive quarters of same-store NOI growth, 7 consecutive quarters of positive leasing spreads, 10 consecutive quarters of leased rate gains, 12 consecutive quarters of balance sheet improvement and 16 consecutive quarters of non-prime asset sales. In addition, the trend for small shop space over the past 2 years has been positive, with a net gain of 1% in 2010, but growing to 29% in 2011 due to move-ins outpacing move-outs. And with regard to tenant accounts receivable and bad debt expense, we have seen continued meaningful reductions over the past 3 years. We are now in the enviable position of having historically low debt maturities and historically high liquidity, with a staggered and balanced maturity profile. We continue to experience historically high leasing velocity with an historically limited tenant watch list. The credit quality of cash flow continues to improve across our portfolio specifically and our sector generally, as described in detail on Page 35 of our updated investor presentation that you can find on our website.
