Final answer:
Comparisons for complex transactions settled ex-clearing typically need to be sent by the end of the trade date, although specific timing can vary by jurisdiction and clearinghouse.
Step-by-step explanation:
The question pertains to the financial industry practice concerning the settlement of complex transactions that require comparison (non-electronic) and are settled ex-clearing. It asks for the time frame within which the comparisons must be sent.
Although this might differ by jurisdiction and specific clearinghouse rules, generally, there's an expectation that these comparisons are made promptly to ensure efficient settlement of trades. Traditionally, the deadline for submission of comparison information would be before the end of the trade date (T+0), but it's best to consult specific exchange or clearinghouse rules for exact timings.
