Struggling smartphone maker BlackBerry Ltd is weighing options that could include an outright sale, it said, and its largest shareholder is stepping down from its board to avoid any possible conflict of interest.

BlackBerry, which pioneered mobile e-mail with its first smart­phones and e-mail pagers, said it had set up a committee to review its options, sparking a debate over whether Canada’s one-time crown jewel is more valuable as a whole or snapped up piece by piece by competitors or private investors.

The company said Prem Watsa, whose Fairfax Financial Holdings Ltd is BlackBerry’s biggest share­holder, was leaving the board as BlackBerry determines its next steps.

BlackBerry’s fate is likely to involve the Canadian Government, which vets foreign takeovers of domestic companies

Canada’s Globe and Mail newspaper said Fairfax was talking to industry and private equity players about possibility taking BlackBerry private. Fairfax did not respond to requests for comment.

Other potential buyers of BlackBerry assets, if not the company itself, could include deep-pocketed Canadian pension funds, as well as some of its rivals. BlackBerry, once a stock market darling, has bled market share to Apple Inc and phones using Google Inc’s Android operating system, and its new BlackBerry 10 smartphones have failed to gain traction with consumers.

BlackBerry shares rose more than 10 per cent to $10.78 in New York and C$11.13 in Toronto in afternoon trading.

But the shares remain well below their levels in June, before the company reported dismal results that included poor sales of the BlackBerry 10 that it viewed as key to a turnaround.

The share price peaked at about C$150 in June 2008, when Black­Berry, then known as Research In Motion, had a market capital­isation of more than $80 billion.

BlackBerry’s assets include a shrinking, yet well-regarded services business that powers its security-focused messaging system, worth $3 billion to $4.5 billion; a collection of patents that could be worth $2 billion to $3 billion; and $3.1 billion in cash and invest­ments, according to analysts.

Even at a conservative estimate, that is more than the company’s $5.4 billion market capitalisation, although analysts say the smart­phones that bear its name have little or no value and it might cost $2 billion to shut the unit.

BlackBerry’s fate is likely to involve the Canadian Government, which vets foreign takeovers of domestic companies.

The Government said it would not comment on speculation, but a spokesman for Industry Minister James Moore said the Government wished BlackBerry well in its search for new options.

Companies tipped as possible partners for BlackBerry have included Microsoft Corp and Amazon.com Inc, as well as Lenovo Group Ltd, where a senior executive said earlier this year the Chinese computer maker would consider a bid for BlackBerry to boost its own mobile business.

But Chinese involvement would trigger deep concerns about security issues from the Canadian Government. Sources say Wall Street bankers have also pitched deals involving BlackBerry to companies such as HTC Corp and Samsung Electronics Co Ltd, so far without success.

Watsa said Fairfax has “no current intention” to sell its BlackBerry shares – some 10 per cent of the company.

But if he remained on the board of directors, he would have a conflict of interest if he wanted to be part of a play for BlackBerry.

“I continue to be a strong supporter of the company, the board and management as they move forward during this process,” he said in a statement.

Analysts expressed scepticism about the new committee, noting that BlackBerry announced a review more than a year ago when it hired JPMorgan and RBC as financial advisers. A source said both are still involved in the current strategic review.

“While a change in structure could result in a higher stock price in the near term, we do not envision any changes that would help BlackBerry reverse the significant smartphone share loss or rapid decline in service revenues,” said Tim Long, analyst at BMO Capital Markets.

A source familiar with the situation said the board decided to form the special com­mittee last week. It was not clear if that decision came before or after it was reported that BlackBerry was warming to the idea of going private to give itself room to recover. He said BlackBerry has been talking to private equity firm Silver Lake Partners about potential collaboration in enterprise computing.
