KKR is raising hackles on Wall Street as its capital markets unit participates in the IPO of Avago Technologies, a semiconductor company that the US buyout group bought with a partner in 2005. The move, which comes as KKR prepares for its own public listing, will net the firm more fees and could upset its traditional relationship with big Wall Street banks, which have long enjoyed large underwriting fees from KKR. The Avago listing was originally expected to raise $400m, but the size of the offer has risen to $500m after a successful roadshow last week.
