NIU has confirmed the existence of a coffee fund.
According to an NIU Today article, the fund has existed for over 20 years at a local bank. The fund was not NIU-authorized, according to the article, and the money was not used for "personal purpose or gain."
The account had $2,100 in it as of August 2012, according to the article. According to a Daily Chronicle article, NIU employees would take scrap metal to the DeKalb Iron & Metal Co., where they sold it and deposited the funds into a coffee fund. The Daily Chronicle article said the company has electronic records that date back to February 2005 and DIMCO checks indicate the company has paid out more than $13,000 in checks to the account since that time.
