“I am thrilled to have this opportunity to return to the FASB and be a part of its standard-setting team,” Day, a FASB practice fellow from 1997-99, said in a statement. “FASB standards are central to the entire system by which investors and other users of financial information make decisions. I am honored to have the chance to do such important and fulfilling work.”

Day has spent most of his 38-year accounting career at EY, which he initially joined in 1986 on the audit staff in St. Louis. Rising through the ranks at the firm, his career path later took him to London, New York, and Munich serving as EY Global’s director of capital markets, as well as EY’s U.S. chief accountant.

He also served as the deputy chief accountant and then later as acting chief accountant in the Office of the Chief Accountant at the Securities and Exchange Commission in Washington, DC, from 2000-03. In addition to being a FASB practice fellow, Day has also been a member of the board’s Emerging Issues Task Force. He is a current or former member of numerous leadership and advisory groups in the accounting profession.

Day earned his undergraduate degree in business administration at Kansas State University.

“I am very pleased that Jack will join us to lead the FASB technical staff,” said FASB Chair Richard Jones. “His years of experience, his global perspective, and his collaborative leadership style will contribute positively to the work we will do in the years ahead.”
