• Reported cash value at grant: $0 (derivative award)
• Shares owned after transaction: not specified in the provided filing

Context
This was an equity compensation award (dividend-equivalent rights tied to RSUs), not a market purchase or sale. Such awards are part of routine executive compensation and do not, by themselves, indicate a buy/sell signal. The dividend-equivalent rights will vest along with the underlying RSUs and convert economically to the equivalent of common stock when vested per the award terms.
