Notes

Corporate actions for fractional shares:

• Fractional shares are eligible for mandatory corporate actions, including dividend distributions and stock splits. However, voluntary corporate actions, such as rights offerings or tender offers, are generally unavailable for fractional shares.
• The trading process remains unchanged.
• For stock splits or reverse stock splits, you may receive fractional shares. For example, if a stock undergoes a 10-for-1 reverse split and you hold 5 shares, you would receive 0.5 shares post-split.
