  • Applies to MSR-mapped investors: Affects clients with MCT MSR API mapped as investors.
  • Reduced latency in concurrent workflows: Decouples the MSRlive API call from Raw Data Best-Ex so that running Raw Data Best-Ex no longer triggers a refresh of MSRlive, eliminating slowdowns in other processes (e.g., saving a Best Ex instance) when multiple users hit the page in quick succession.
  • On-demand MSR refresh: Users now explicitly control when loan-level MSR values from MSRlive are repopulated, preventing simultaneous overwrites and reads.
• Multiple Users Can Now Run Best Ex – Multiple users can now run a Best Ex simultaneously on the same client code, each on their own population of loans — no more stepping on each other’s pipelines.
  • New User dropdown under Raw Data Best Ex lists every user with loans loaded in exceptions, with their loan count.
  • Switch the dropdown to see another user’s population — full visibility is preserved.
  • Selection persists through the entire workflow: Best Ex, pricing, tape posting, and commitment.

• Best Ex: Ineligible Pricing Override – Added a new “Ineligible Pricing Override” checkbox to the Best Execution Filters section of the Best Ex Analysis tab. [View Screenshot]
  • When enabled, Can’t Go and Must Go normalization rules continue to apply for best-execution and eligibility decisions, consistent with existing “Raw Data Best Ex” and “Hedged Only Best Ex” behavior.
  • Excel export from the Commit Loans UI now includes all available pricing (ignoring Can’t Go / Must Go restrictions) when the override is enabled.

  • No workflow changes — Existing Float Calculation functionality (save/load behavior, popup UI, and API endpoints) remains unchanged; this release simply broadens user access.
• Attribute Restriction – Construction Loans – Added Construction Loan as a new attribute option in the Best Ex tab’s Attribute Restrictions tool. Users can now create restriction rules that match loans on Construction Loan status (Y/N), following the same pattern as existing attributes like PIW, eNote, FTHB, and Escrow Holdback. The new attribute is available in both the restriction edit popup dropdown and the rule evaluation logic, so loans are now correctly evaluated against Construction Loan restrictions during Best Ex analysis.

  • Pricing comparisons across loan programs are more accurate by filtering on the applicable LTV range rather than treating all LTVs uniformly.
