Abstract: A system and method are provided for executing exchanges of fractional amounts. The method includes providing, via an ordering subsystem, an interface to accept proposed exchanges for notional amounts that result in a fractional amount of at least one asset, and, optionally, a whole number of the at least one asset. The method includes, for each provided exchange, providing the proposed transaction to a conversion system for converting notional amounts into whole and fractional amounts. The method includes, for each of the at least one asset, executing a trade for the at least one asset by ordering an excess amount of the at least one asset responsive to the fractional amount, and executing, with the enterprise risk subsystem, a second trade based on the reported acquisition, and the excess amount less the fractional amount.

Abstract: Described are embodiments for allowing the negotiation of a continuous presence layout. Specifically, in embodiments, an offer is generated by a client that includes attributes for displaying continuous presence video information. The attributes include, in some embodiments, one or more window identifiers, one or more bandwidth limit identifiers, one or more group numbers, and/or one or more ranks. The offer is sent to a server which transmits an answer to the offer. Once the attributes for the continuous presence layout has been negotiated, the server uses the attributes to format video content sent to the client.
