Sheikh Mohammed's Darley Stud Management announced 2002 fees for 25 of its 26 stallions, and not unexpectedly some will be going down and some up. The outfit's highest-priced stallion, Machiavellian, had his fee increased for £60,000 to £80,000, and another heavyweight, Halling will be going up from £15,000 to £30,000. Both stallions stand at Dalham Hall Stud near Newmarket, England. Downward fees include the one for Singspiel, from £20,000 to £15,000."The world has changed and so have we," said Sam Bullard, head of nominations. "Our message is clear: Darley's commitment to the business interests of mare owner is absolute, and we're bringing down the cost of breeding so that mare owners who are producing high-class horses can thrive."Darley plans to announce a fee for millionaire Fantastic Light following Saturday's Breeders' Cup at Belmont Park.
