Skilled Healthcare Group Inc. has been ordered to pay $671 million for failing to provide adequate staffing at its assisted-living facilities.

A Humboldt County jury awarded the damages Tuesday in the class-action lawsuit against the company based in Foothill Ranch, more than seven months after the civil trial began.

The lawsuit alleges that the company violated a California statute that mandates 3.2 nursing hours per patient per day.

The complaint covers the period from 2003 to 2009. It represents about 32,000 patients at 22 facilities.

The company says it intends to pursue "various post-trial motions," which could include an appeal.

The company says the jury awarded $613 million for statutory damages and $58 million in restitution.

Next week the jury will decide the extent of punitive damages.
