Passage: On 8 January 2015, CONCACAF and CONMEBOL announced the 24 U.S. metropolitan areas which had indicated interest in hosting matches.The stadiums were chosen following a bidding process, with the minimum capacity to be 50,000. The final list of venues, anticipated to number between 8 and 13, was to be announced in May 2015. However, the list was not released and speculation regarding whether the tournament will be able to move forward arose because Interpol red notices were issued for the former presidents of the CONMEBOL and CONCACAF confederations in relation to the 2015 FIFA corruption case, including allegations that they accepted significant bribes in relation to the $112.5 million broadcasting deal for the event. However, officials from CONMEBOL expressed a desire to move forward with the event despite the scandal.On 19 November 2015, the ten venues selected for the tournament were announced by CONCACAF, CONMEBOL, and US Soccer Federation.

Question: In what month was the final list announced?
May
