NASCAR and Grant resolved the legal issue during a mediation held December 3 in New York. Settlement terms remain confidential, and both parties agree not to publicly discuss the details of the case or the terms of the agreement going forward.

Neither NASCAR nor Grant admits liability or wrongdoing by way of the settlement.

"We're glad to have the case settled on mutually acceptable terms," NASCAR spokesperson Ramsey Poston said in a statement released Thursday. "NASCAR remains dedicated to maintaining a professional work environment for all employees at all times, and we wish Ms. Grant well in her future endeavors."

In June, Grant filed the multi-million dollar suit, claiming 23 incidents of sexual harassment and 34 incidents of racial and gender discrimination. She also alleged that she was wrongfully terminated.

NASCAR denied Grant's allegations and shortly after conducted its own investigation into the matter. The sanctioning body eventually fired two officials who were involved in Grant's claim.

Grant was the first African-American female to work for NASCAR as an official. She served as a technical inspector for the series known then as the Busch Series from 2005 to 2007.
