Chairman Michael Steele said: "Tony has made a major contribution to the club in his four years associated with it, and we're delighted to have his support and contribution."
He added: "Whilst we have a robust business consistently generating modest profits in difficult circumstances, working capital is always an issue, and this investment will be a significant boost to the club."
Abbott said: "I am determined to see Halifax RLFC back where we know they belong, in Super League."
