Item 4. Purpose of Transaction.
As previously disclosed by Bel Fuse Inc. (“Bel”) in its Schedule 13D filed with the SEC on September 9, 2004, Bel has approached Artesyn Technologies, Inc. (“Artesyn”) to discuss the possibility of a merger involving Bel and Artesyn. On May 11, 2005, Bel sent a letter to the Board of Directors of Artesyn, expressing its disappointment with the recent performance of Artesyn’s stock price and its continued frustration with Artesyn’s unwillingness to meet with representatives of Bel to explore the possible benefits of a strategic combination. Bel’s letter to Artesyn further indicated Bel's intention to either decrease the consideration proposed to be paid by Bel or withdraw its proposal if Artesyn does not arrange a meeting with Bel by June 3, 2005. Bel continues to own 2,037,500 shares of Artesyn’s common stock.
