Borusan Holding At A Glance In 4 major business areas, with 7.000 dedicated employees Borusan Group has been among the pioneers of industrialization and corporate governance in Turkey throughout its 70 years of history. The group currently operates in four major business areas including steel, distributorship, logistics and energy. In 2006 Borusan Group signed the United Nations Global Compact Policy and it supports and adheres by the principles of good corporate governance and sustainability as a prerequisite of longterm and permanent components of success. Contribution to Community Borusan has adopted as one of its primary principles the concept of giving back to the community with which it does business. In order to better fulfill its social responsibility vision, the activities of the Asım Kocabıyık Culture and Education Foundation, which was founded in 1992 and Borusan Culture and Arts, established in 1997, came together under one roof in 2008 to become the Borusan Kocabıyık Foundation. With a deep social responsibility consciousness, the Borusan Group established the Borusan Center for Culture & Arts on October 15, 1997. The Borusan Center for Culture and Arts is a member of the International Society of Contemporary Music (ISCM) and the European Music Council (EMC) and organizes the annual Mediterranean Contemporary Music Days. Though it began with modest numbers, the chamber orchestra was transformed into one of the leading Turkish philharmonic ensembles under its former artistic director and principal conductor Gürer Aykal. Giving its concert premiere in May 1999, BIPO has since become a prominent element of Istanbul s cultural scene.
