The EBU does, however, pay for the air or train tickets of referees and officials that travel away from home for an EBU fight. Other rules are also imposed on EBU recognized events, but not many of the EBU rules interfere with the fighting rules to be followed during the fight itself. The EBU recognizes world titles sanctioned by the WBA, WBC, IBF, WBO and IBO. A boxer holding a world title is rendered ineligible for EBU, including , rankings. A male boxer must have competed in at least eight bouts to be eligible for rankings. For female boxers, it is four bouts. At least five of a boxer's last 10 bouts must have taken place in Europe and sanctioned by an EBU affiliate association, two of which in the last 24 months, to be eligible for rankings. A boxer challenging for a European title from another sanctioning body is disqualified from rankings for nine months. A boxer holding such a title will only be eligible for rankings after 12 months from the time of having relinquished it.
