Third-Quarter Business Highlights:


•	Revenues from Asset management, administration, and distribution fees increased primarily from higher assets under administration in our Investment Managers segment.


•	Our average assets under administration increased $94.8 billion, or 16%, to $654.0 billion in the third-quarter 2019, as compared to $564.2 billion during the third-quarter 2018 (see attached Average Asset Balances schedules for further details).


•	Our average assets under management, excluding LSV, increased $5.5 billion, or 2%, to $233.0 billion in the third-quarter 2019, as compared to $227.5 billion during the third-quarter 2018 (see attached Average Asset Balances schedules for further details).


•	Sales events, net of client losses, during third-quarter 2019 totaled approximately $42.7 million and are expected to generate net annualized recurring revenues of approximately $33.2 million when contract values are fully realized.


•	Our earnings from LSV decreased by $4.1 million, or 10%, to $37.6 million in third-quarter 2019 as compared to $41.7 million in third-quarter 2018. The decrease in earnings was due to negative cash flows, client losses, reduced performance fees earned by LSV and a decline in assets under management from market depreciation.


•	We capitalized $7.3 million of software development costs in third-quarter 2019 for continued enhancements to the SEI Wealth Platform^SM (SWP). Amortization expense related to SWP was $10.7 million in third-quarter 2019.


•	Our effective tax rates were 18.9% in third-quarter 2019 and 18.6% in third-quarter 2018.


•	We repurchased 1.4 million shares of our common stock for $81.4 million during the third-quarter 2019.
