The Financial Post reports in its Friday edition that Postmedia Network Canada posted a net loss of $20.1-million in its latest quarter compared with a loss of $20.8-million a year earlier as its revenue fell 13 per cent. A Canadian Press dispatch to the Post says that the publisher of the National Post and other newspapers says the loss amounted to 20 cents per diluted share for the quarter ended Feb. 29 compared with a loss of 21 cents per diluted share a year earlier. Revenue for what was Postmedia's second quarter totalled $97.3-million, down from $111.8-million in the same quarter last year. The company says the change was primarily due to a drop in advertising revenue to $43.2-million compared with $54.5-million a year ago, while circulation revenue fell to $32.9-million compared with $37.0-million. Postmedia closed unchanged in Toronto at $1.23 a share.
