Context Sales made under pre-established 10b5-1 plans are common for executives to manage tax/estate needs and are generally considered routine rather than a clear signal of management’s view of the company. Weighted-average prices and the multiple-trade ranges mean the reported averages mask smaller fills at different prices; the filer offers to provide exact per-trade details upon request (per the footnotes).
