The $2.9 billion write-down was largely related to the publishing assets' declining value.
The unit has borne heavy legal costs related to U.K. investigations of a phone hacking scandal. Its British tabloid, News of the World, was closed in July last year. Restructuring is ongoing at its Australian newspapers and at its advertising insert group, News America Marketing. Both divisions face "challenging pressures that will adversely impact profits," chief operating officer Chase Carey told analysts.
Although the write-down was a non-cash charge, it resulted in a loss for the three-month period. News Corp.'s stock fell 82 cents, or 3.5 per cent, to $22.90 in after-hours trading.
Tuna Amobi, an equity analyst with Standard & Poor's, said the accounting manoeuvr was a way to prepare for the spin-off and set expectations low. News Corp.'s entertainment assets, which won't be spun off, are far more profitable. They include Fox News Channel and the 20th Century Fox movie studio.
"Either way you look at it, the publishing assets are going to be the under-appreciated sibling, by far," Amobi said.
The loss for the April-June period came to 64 cents per share. That compared to net income of $683 million, or 26 cents per share, a year ago.
Excluding special charges, earnings were 32 cents per share, matching the estimate of analysts polled by FactSet.
Revenue fell 7 per cent to $8.37 billion. The figure was short of the $8.78 billion expected by analysts.
Pay TV programming revenue continued to stand out, rising 15 per cent to $2.48 billion, thanks to higher fees from distributors and increased advertising. Operating profit rose 26 per cent to $792 million, which accounted for two-thirds of the company's operating profit overall.
Movie studio revenue fell 14 per cent to $1.74 billion, as the company failed to match the box office success of last year's "Rio". Revenue from its Fox broadcast TV network and stations fell 3 per cent to $1.08 billion, while revenue from its Sky Italia satellite TV company fell 15 per cent to $880 million due to subscriber losses amid a weak Italian economy.
Publishing revenue from newspapers including The Wall Street Journal fell 14 per cent to $2.02 billion.
The company, controlled by founder and CEO Rupert Murdoch, expects adjusted segment operating income to increase in the "high single- to low double-digit" percentages in the coming fiscal year through next June, from a base of $5.6 billion in the year just ended. In the most recent fiscal year, adjusted segment operating income rose 13 per cent.
