An investigation by The New York Times has found a total of five women who have received payouts from either Mr. O’Reilly or the company in exchange for agreeing to not pursue litigation or speak about their accusations against him. The agreements totaled about $13 million.

Two settlements came after the network’s former chairman, Roger Ailes, was dismissed last summer in the wake of a sexual harassment scandal, when the company said there was no room for behavior that “disrespects women or contributes to an uncomfortable work environment.”

The women who made allegations against Mr. O’Reilly either worked for him or appeared on his show. They have complained about a wide range of behavior, including verbal abuse, lewd comments, unwanted advances and phone calls in which it sounded as if Mr. O’Reilly was masturbating, according to documents and interviews.

The reporting suggests a pattern: As an influential figure in the newsroom, Mr. O’Reilly would create a bond with some women by offering advice and promising to help them professionally. He then would pursue sexual relationships with them, causing some to fear that if they rebuffed him, their careers would stall.
