Facebook reports loss after shareholder payouts

Facebook has reported a $157m (£100m) loss on payments to shareholders, including chief executive Mark Zuckerberg, in its first results since its eagerly-anticipated stock market listing in May.
The loss was mainly due to one-off expenses associated with its flotation - excluding staff share schemes, Facebook would have made a profit of $295m.
However, it was the news about slowing growth that caused its shares to tumble, as the BBC's Michelle Fleury reports from New York.
