Ladies' Professional Golf Association Tour commissioner Ty Votaw has announced his resignation effective at the end of the 2005 season.

No reason was given for the decision.

The 42-year-old Votaw has been commissioner since 1999. He oversaw a period of extensive growth in women's professional golf. 

During Votaw's tenure, the number of tournaments that offer $1 million in prize money has risen from 12 to 30. Four tournaments now offer at least $2 million in total prize money. 

The average purse per tournament has also grown from $840,000 to more than $1.4 million. 

The LPGA Board of Directors has established a 10-member search committee to look for Votaw's replacement.
