4242. Independent price verification and adjustment

Or jump to a Series:

    1. A Dealer Member must verify its security prices at each month‑end by comparing them with independent (third‑party) pricing sources.

    2. The verification work must detect and quantify all pricing differences (distinguishing adjusted and unadjusted differences).

    3. An appropriate Executive must:

      1. on a monthly basis, approve the resolution of all material differences, and

      2. on an annual basis, review and verify the continued appropriateness of the existing pricing sources. Where appropriateness is identified as a material concern, the pricing sources used must be changed.

    There is no history log for this rule.
