With respect to our liability or liquidity rather, at the end of the third quarter 2010, we had cash on hand of $180 million excluding properties and default; $120 million of this was restricted for specific purposes including swap collateral, prepaid rents, leasing commissions and tenant improvement reserves as well as property tax and insurance reserves and $60 million of this cash was unrestricted and has been available for general corporate purposes. This is $10.8 million less than the unrestricted cash balance at the end of the second quarter of 2010. These funds were used to pay for leasing cost including the release renewal of Southern California Gas Company, a gas company tower in downtown Los Angeles and Disney Corporation in Glendale.
Addressing debt maturities remains a continuing focus. Subsequent to the end of the third quarter, we extended the loan on Plaza Las Fuentes till September 29, 2011. In order to complete a one-year extension of this loan, we will require to make a $9 million paydown using a combination of $6.5 million of restricted cash that we funded on October 29, 2010 and $2.5 million of restricted cash, which was held by the lender in reserves. There are no additional maturities in 2010.

In the third quarter and through October 31st, we leased 1.1 million square feet in our wholly-owned assets. In addition, we leased 230,000 square feet in properties held in a joint venture with Charter Hall.
The total leasing through October 31st was 1.3 million square feet of lease renewals and new tenants and our total leasing year-to-date is in excess of 2 million square feet.
