On March 22nd, we were delighted to celebrate the grand opening of City Creek Center in Salt Lake City, Utah. It was truly a fantastic event with thousands and thousands of people present. We handed out over a 100,000 directories just in the first day and the entire community embraced this project enthusiastically. With 92 eventually a 100 tenants opening and the rest of the space either leased or committed, the center is open beyond our wildest expectations. We have invested $75 million. In 2012 the center will be accretive and will likely add about $0.05 to the year which was in our guidance. For 2013 our first full 12 months we're expecting a 12% return.

The streams (inaudible) through the entire shopping center. The two 18 foot waterfalls and the (inaudible) as the center has been designed to the BMDM umbilical cord to the greater downtown. Almost universally, we are hearing from our tenants that initial sales performances well exceeded preopening expectations. Five weeks after opening, traffic continues unabated. We are really proud of this asset and speak volumes about our team and our sponsorship of similar developments around the world. We welcome all of you on this call to come to Salt Lake City and see it as we believe you will be very impressed with this product.
