LOS ANGELES — Twenty-First Century Fox disclosed on Monday that it had incurred costs of $10 million “related to settlements of pending and potential litigations” during its fiscal third quarter in the aftermath of sexual harassment allegations at Fox News.

That revelation was made in a regulatory filing to the Securities and Exchange Commission in which 21st Century Fox said it “has also received regulatory and investigative inquiries relating to these matters and stockholder demands to inspect the books and records of the company which could lead to future litigation.” The company said that in the nine months leading up to March 31, it had incurred $45 million in costs tied to litigation related to harassment allegations.

The New York Times on April 1 disclosed financial settlements involving multiple women who had accused Bill O’Reilly, the top-rated Fox News personality, of sexual harassment or behaving inappropriately. Fox News ousted Mr. O’Reilly on April 19 after conducting an internal investigation; advertisers had also left his show in droves. He has denied any wrongdoing. The housecleaning continued on May 1 with the dismissal of one of the network’s co-presidents, Bill Shine, a protégé of Roger Ailes, who was pushed out as the chairman of Fox News last summer amid his own sexual harassment scandal. Mr. Ailes has also denied any wrongdoing.

Reporting its first quarterly earnings since Mr. O’Reilly’s departure, 21st Century Fox executives managed to avoid discussing the upheaval almost entirely on Wednesday. In a 34-minute call with analysts, Lachlan Murdoch, the executive chairman, and James Murdoch, the chief executive officer, steered attention toward climbing subscriber fees for the company’s cable channels and their high expectations that regulators would approve the company’s $14.3 billion buyout of Sky, the British satellite TV giant.
