EquiLend Announcement: FINRA Releases Updated SLATE Draft v1.1 for SEC Rule 10c-1a

On February 12, 2025, FINRA published an updated SLATE (Securities Lending Aggregated Transaction Engine) draft v1.1, a critical step in the ongoing implementation of SEC Rule 10c-1a. As the industry prepares for new securities lending transaction reporting requirements, EquiLend remains committed to supporting our clients with a comprehensive, automated and scalable 10c-1a reporting solution that seamlessly integrates with FINRA’s evolving framework.

Key Updates in FINRA’s SLATE v1.1 Specification

FINRA’s SLATE system is designed to facilitate the collection, validation and dissemination of securities lending transaction data as required under Rule 10c-1a. The updated draft v1.1 provides further clarity on key aspects of the reporting framework, including:

  • SLATE reporting hours will be from 6:00 a.m. to 11:59 p.m. ET, with reporting required by system close.
    • Loan events effected by 7 p.m. are required to be reported on trade date
    • Loan events effected after 7 p.m. are not due until next business day
  • Additional clarity on JSON field names and character lengths
  • Enhanced Data Standardization & Validation
    • Introduction of file recorded for tracking and sequencing loan events
    • Stricter validation on MPID, CRD/IARD and LEI identifiers for lenders, borrowers and intermediaries
    • Clearer rules on loan identifiers, execution venues and security identifiers

As FINRA finalizes SLATE, EquiLend continues to monitor developments to ensure a fully integrated 10c-1a reporting solution. Our solution will:

  • Seamlessly Connect with FINRA’s SLATE System – Enabling automated and accurate transaction reporting
  • Adapt to Regulatory Updates – Incorporating the latest technical and operational requirements as they evolve
  • Minimize Compliance Burden – Streamlining data submission through efficient and cost-effective workflows

Whats Next?

EquiLend is actively engaging with FINRA and industry stakeholders to ensure our solution meets evolving compliance requirements. We encourage market participants to review the latest SLATE draft v1.1 and prepare for the upcoming implementation of Rule 10c-1a.

We will continue to keep our clients informed of further regulatory updates, system developments and industry best practices as we move toward compliance.
