The floundering Daily News lost $90.4 million over the last three years — including $23.7 million of red ink in the year ended Dec. 25.

Revenue last year tumbled 14.2 percent, to $144.78 million, according to a regulatory filing on Monday.

Paid print Monday-to-Friday circulation slipped to 182,472 in the second quarter, according to the Alliance for Audited Media.

Mort Zuckerman sold the teetering tabloid to Tronc, the owner of the Chicago Tribune and the Los Angeles Times, in September for $1.

Tronc agreed to assume pension liabilities and bank debt as part of the deal.

Zuckerman, who bought the paper out of bankruptcy in 1993, is in declining health.

He had tried unsuccessfully to sell the paper in 2015 when it was losing $29.1 million on revenue of $168.67 million.

The Daily News was able to trim its losses in 2016 by $5.3 million over 2016 only by aggressively slashing staff and other expenses. Compensation costs tumbled 16.1 percent in 2016 from the previous year.

The declining circulation meant the company was able to shave $1.8 million from its expenditures on newsprint and ink. The newsroom was hit with deep cuts in both 2015 and 2016.
