Routine resale notice filed under Form 144; standard broker-assisted placement.

Form 144 is a regulatory notice that permits affiliates to report proposed sales; it does not itself execute trades. The filing lists 409,000 shares of Class A common and names Morgan Stanley Smith Barney LLC as the broker.

Cash‑flow treatment is not stated in the excerpt. Timing and final transaction details depend on whether the broker completes the sales and on Rule 144 conditions such as holding period and volume limitations.
