Organisers of Wimbledon tennis championship have put away $3.87 million to cover rain disruptions during matches, reports Xinhua.

A Championship Ticket Refunds Reserve has been set up by the Lawn Tennis Association (LTA), the governing body of British tennis and joint organisers of the grass court grand slam, members were told Wednesday.

The reserve will be used to refund spectators who see less than an hour's play due to poor weather.

The refund amount was not specified nor were the members told when the new rules would come into effect.

Wimbledon is a major money-spinner for LTA.

Ticket holders are also eligible for a half refund if there is more than one hour's play but less than two hours' play.

In January, the All England Club announced it was to build a retractable roof over Centre Court.

Construction on Centre Court is expected to begin in 2006 and a translucent roof should be in place for the 2009 championships.
