Four years after it was established in an effort to reduce high school drop out rates, the Kanye West Foundation has closed its doors. Why? No one knows.

According to The Boombox, news of the closure broke after the charitable organization’s former executive director, Joseph Collins, emailed colleagues to say he was out of a job and inform them that the phone had been disconnected.

“I am reaching out to let you know that the Kanye West Foundation (kanyewestfoundation.org) has officially closed it doors after a successful 4+ years of programming and events [sic],” Collins wrote in the email. “It has been an incredible experience working with Kanye and the board to realize his mother’s vision and I am honored to have been given the opportunity to lead the Foundation.”

The organization’s website is still live. According to the site, its mission is – or was – to “help combat the severe dropout problem in schools across the United States by partnering with community organizations to provide under-served youth access to music production programs.”

Kanye’s mother, Donda West, is credited with founding the organization. She died in 2007 from complications related to a surgical procedure.

The foundation reportedly raised an average of $492,000 a year primarily from companies with which West did business. Madison Square Garden, for example, dolled out $151,754 to the charity. The clothing company Karmaloop reportedly anted up $20,000 for the cause. It’s unclear if West himself contributed any of his own money to the organization.

While there is some speculation that Donda West’s untimely death may have contributed to the demise of the foundation, no one knows for sure why the organization went belly up so suddenly.
