The upsurge was mainly due to elevated average long term AUM and performance fees, along with revenues associated with the addition of Clarion and EnTrust.

However, distribution and service fees were down 13.7% year over year to $78.9 million.Operating expenses increased 10.0% to $686.6 million on a year-over-year basis. The rise was chiefly due to higher compensation and benefits (up 15.3%), and expenses related to impairment of intangible assets.Adjusted operating margin of Legg Mason was 22.5%, significantly up from 11.3% in the prior-year quarter. Lower acquisition and transition-related costs led to the rise.Solid Assets PositionAs of Jun 30, 2017, Legg Mason’s AUM was $741.2 billion, down slightly year over year from $741.9 billion. Of the total AUM, fixed income constituted 55%, equity 26%, liquidity 10% and alternatives represented 9%.AUM inched up 1.8% sequentially from $728.4 billion as of Mar 31, 2017, driven by positive market performance of $8.4 billion, long-term net inflows of $0.5 billion and $0.7 billion in positive foreign exchange. These positives were partially offset by liquidity outflows of $11.5 billion. Notably, change in category of $16.0 billion of separately managed account assets which were previously classified as Assets Under Advisement also positively impacted AUM.Notably, long-term net inflows of $0.5 billion included equity inflows of $1.0 billion and fixed income inflows of $0.3 billion, partially mitigated by alternative outflows of $0.8 billion.
