The owner of London's Canary Wharf, a major business district, rebuffed a raised GBP2.6 billion ($4.1 billion) bid for the financial district from Qatar and a North American investor saying it was too low.

Songbird Estates said the 350 pence ($0.78) per share offer from Qatar Investment Authority (QIA) and Brookfield Property Partners ", its unique position and future growth potential".

The Canary Wharf financial zone was established about 25 years ago on former docks and is in a Songbird portfolio that includes part ownership of the landmark "Walkie Talkie" skyscraper in the City, London's traditional business area.

A revival in London's office property market and Canary Wharf's expansion plans have stirred interest in Songbird.

Canary Wharf is preparing to start work on two major developments: a 60-storey tower with the first residential property on the estate and a 20-acre waterside site with 3,100 homes and office buildings, as well as a school and more shops.

However, Canary Wharf's complex ownership structure with two layers of shareholders, one in Songbird and another in Canary Wharf Group, has tended to leave Songbird shares trading at a discount to their net asset value.

Songbird owns 69.4 per cent of Canary Wharf Group while US-listed Brookfield, which operates and invests in office and industrial property, is the second largest shareholder in the unlisted company with 22.1 per cent.

Meanwhile, Qatar's sovereign wealth fund owns 28.6 per cent of Songbird. New York-based investor Simon Glick has almost 26 per cent and China's sovereign wealth fund owns 15.8 per cent.

QIA and Brookfield made a GBP2.2 billion ($3.45 billion) approach for Songbird in November sending its shares soaring as much as 22 per cent to 320 pence, but it was rejected.

HOSTILE MOVE

In a hostile move, QIA and Brookfield took their new joint all-cash bid directly to shareholders on Thursday. Announced less than two hours before a deadline to submit a revised bid, it represented a 33.6 per cent premium to Songbird's closing share price on Nov. 5, the day before the first approach.

Songbird said in a brief response its pro forma adjusted net asset value was 381 pence per share as of Nov. 27 and there were other areas of value within the company not reflected in that valuation. It said it would write to shareholders with its detailed view of the offer in due course.

Songbird's shares were down 3 per cent at 313 pence by 0950 GMT, after an early rise to 335p fizzled out.

"Whilst we believe 350 pence is still too low and doesn't attribute any value to the future prospects or management, ultimately the shareholders have to decide whether they want to take the liquidity now or continue to invest in the longer-term outlook of what is arguably a unique estate at Canary Wharf," Miranda Cockburn, analyst at Oriel Securities, said in a note.

A successful bid would add to Qatar's significant presence in London. The Shard, western Europe's tallest skyscraper, and department store Harrods, are among its high-profile properties. – Reuters
