From the link:
"OJSC will remain its own separate tax-exempt 501(c)(3)corporation with complete control over all aspects of the club. This affiliation allows OJSC to partner with fellow non-profit CDA Slammers FC to expand and enhance opportunities for every child in the club. Effective immediately, OJSC’s competitive program, currently known as “Orange County Premier” will be known as “CDA Slammers Orange.”
Translation - We wanted to move to SCDSL and this was the easiest way.
