Twenty-First Century Fox reported on Wednesday that profit more than doubled in the three months that ended Dec. 31 — thanks to a hefty tax gain and strength in its cable network division.

Fox said net income attributable to shareholders increased to $1.83 billion, or 99 cents a share, from $856 million, or 46 cents, last year.

Adjusted earnings totaled 42 cents. The results were aided by a $1.34 billion gain from the recent changes to the US tax law, the company said.

Revenue rose 4.6 percent, to $8.04 billion. Analysts expected 38 cents a share on revenue of $7.87 billion.

By division, the cable network division said revenue grew 11 percent, to $4.4 billion, while broadcast TV revenue fell 5.8 percent, to $1.81 billion.

Fox’s entertainment division saw revenue dip 1 percent, to $2.25 billion.

Fox, which is in the process of selling the majority of its assets to Disney for $52.4 billion, said it will continue to focus on making its content globally available as it invests in sports and live news.

Last month, Fox acquired the rights to air the NFL’s Thursday Night Football games over the next five years in a deal valued at $3.3 billion.

Fox shares slipped 6 cents in after-hours trading, to $36.
