Thank you. And I'll now turn the call over to Ed Fritsch.Ed Fritsch Thanks Tabitha. Good morning and thank you everyone for joining us today. We had a solid quarter on a number of fronts and 2010 and is proving to be a good year for our company. At the outset of the year we forecasted FFO to be 231 to 249 per share. Through the year we've tightened guidance to the range of 244 to 246 with the midpoint increasing from 240 at the start of the year to 245 and this includes the dilative impact of the non core sales we closed earlier this year. Our team has performed well in a number of sectors, particularly with respect to leasing volume, cost control and portfolio improvement. Our operating fundamentals, while still clearly challenging have been somewhat better than we originally anticipated. Leasing volume was again strong with 1.4 million square feet leased in the quarter and for the first time in three years we leased over a million square feet of second gen office space in a single quarter. Total office leasing for the first nine months of 2010 was respectable at 2.8 million square feet, compared to 1.8 million square feet for the first nine months of 2009, a 56% increase.
