Register of TDC Determinations
This register provides a summary of Trading Dispute determinations made by the TDC.
The TDC’s determinations are made in accordance with Section W of the BSC.
All Trading Queries must be raised within set timescales, promoting the timely detection
and prompt rectification of errors. When considering a Trading Query or Dispute,
the TDC decides whether a settlement error has occurred (defined in Section W1.3).
The TDC may apply precedent in deciding whether settlement error has occurred. The
TDC may however consider two seemingly similar Trading Disputes but reach different
determinations regarding Settlement error due to the unique circumstances of each
Trading Dispute. In all cases, the reasons for the TDC’s determination are given.
Refer to the table below to download the Register of TDC Determinations and an Explanation
of Terms.
