'We have not been immune to the rapidly unfolding financial market crisis,' Songbird chairman David Pritchard said in a statement. He added that it is too early to assess the full impact of the Lehman Brothers crisis on the company's property portfolio. Lehman, which filed for bankruptcy protection on 15 September, has a lease for 1,023 million sq ft (95,000 m2) at Canary Wharf.

Songbird's total investment portfolio comprises a total of 7.9 million sq ft, of which 99,7% has been leased.

Songbird said that it has concluded rental agreements of 200,000 sq ft in the first half of the year. Additionally, the company has entered into 'exclusive negotiations' with JP Morgan and signed heads of terms for the construction of a new European headquarters at Riverside South.

Songbird Estates manages the investment of its main subsidiary, Canary Wharf Group, which focus on the development of Canary Wharf in London's Docklands.
