  reason: Regulatory uncertainty around the timeline for receiving the required U.S. and Canadian bank-regulatory approvals;
    TD could not predict when approvals would be obtained, and the parties mutually agreed the deal would not close in a commercially
    reasonable timeframe. The termination announcement followed a year of heightened regulator scrutiny across large bank
    M&A and TD's own AML compliance issues, which later resulted in a $3B+ U.S. AML settlement in 2024.
