SCHEDULE 13D

Item 1. Security and Issuer

     This statement constitutes Amendment No. 22 to the Schedule 13D relating to the shares of Common Stock, par value $0.01 per share (the “Shares”), of XO Holdings, Inc., a Delaware corporation (the “Issuer”), and amends the Schedule 13D relating to the Shares filed on January 27, 2003 and amended by each of Amendment Nos. 1 through 21 (as amended by Amendment Nos. 1 through 21, the “Original 13D”), on behalf of the Filing Persons (as defined in the Original 13D). Capitalized terms used herein and not otherwise defined have the respective meanings ascribed thereto in the Original 13D.

Item 4. Purpose of Transaction

     Item 4 of the Original 13D is hereby amended by adding the following:

     In the period following October 26, 2009, the stated termination date of ACF Holding’s $0.80 per share offer, representatives of ACF Holding continued to discuss the matter with members of the Special Committee and its advisors. ACF Holding’s bid required a majority of the minority stockholders to vote in favor of the merger proposal. During those discussions, a variety of criteria were considered. No counteroffer was ever received from the Special Committee. The Special Committee expressed the view that the $0.80 per share offer undervalued the Issuer and that it would not make a counteroffer. Representatives of ACF Holding pointed out that the CLEC industry faced difficult times ahead and that ACF Holding believed that its offer of $0.80 per share was fair, especially in light of the fact that it required a majority of the minority stockholders to vote for it in order to become effective. Representatives of ACF Holding also pointed out that ACF Holding had raised its proposed merger price from $0.55 to $0.80 per share without receiving a counteroffer. They also stated that the initial offer was made when the market price for the Shares was under $0.30 per share. In light of all of the above facts, ACF Holding is now terminating its offer.

Item 6. Contracts, Arrangements, Understandings or Relationship with Respect to Securities of the Issuer

     The information set forth above in Item 4 is incorporated herein by reference.
