GREENSBORO, N.C. (AP) _ The Bowl Championship Series has issued a clarification of its computer-driven selection formula, BCS Coordinator John Swofford said Thursday.

BCS administrators met Tuesday and decided that exempt games and conference championship games will now be included in all elements of the standings.

However, as they have in years past, wins in exempt games and conference championship games will not be counted toward the nine-game victory total needed to qualify for the BCS at-large selection pool.

``Teams who choose to participate in the preseason exempt games risk the negative impact of a loss in the formula, so they should be able to see the value of a victory,'' Swofford said in a statement.

The BCS standings use The Associated Press media poll and the USA Today-ESPN coaches poll, eight computer ratings, strength-of-schedule and win-loss records in determining its overall point total.

The BCS formula went unchanged for two seasons before this year. But controversy arose in 2000 over whether Miami or Florida State, each with one loss, was the worthy opponent to play undefeated Oklahoma for the national title.

Swofford reaffirmed the BCS practice of counting just one victory over a team per year in the BCS formula. If a team defeats another team twice during the season _ including exempt and conference championships _ it will receive quality points for only one victory.

The BCS title game will be played Jan. 3 in the Rose Bowl.
