          <courtOrBodyNameAndLocation>Securities and Exchange Commission</courtOrBodyNameAndLocation>
          <actionDescription>The SEC's order found SEI Investments Global Fund Services (SGFS) caused an unregistered money market fund for which SGFS served as fund accountant and administrator to violate affiliated transaction rules when that fund sold its shares to, and redeemed them from, a set of affiliated mutual funds. While the unregistered money market fund was permitted to sell its shares to , and redeem them from the mutual funds, it could do so only if it operated in conformity with certain regulatory requirements, including Rule 2A-7 and section18 of the Investment Company Act of 1940. The order finds that due to the manner in which SGFS performed accounting for the unregistered money market fund, it failed to satisfy those regulatory requirements from 2008 through 2012.</actionDescription>
          <dispositionOfProceeding>The action has been resolved pursuant to an offer of settlement that was accepted by the SEC, as set forth in an order instituting cease-and desist proceedings dated 4/26/18. SGFS must cease-and-desist from further violations and a pay a fine of $225,000.</dispositionOfProceeding>

SEIL provides no services for SITA nor to any investors in the United States.</actionDescription>
          <dispositionOfProceeding>A fine of approximately 900,000 British Pound. No deficiencies were found by the FCA in the bank accounts and trust letters used by SEIL to appropriately separate client monies from its own assets. SEIL has since remediated the identified deficiencies.</dispositionOfProceeding>
