Section 16 regulatory
"in a transaction exempt from Section 16 of the Securities Exchange Act of 1934"
Section 16 is a U.S. securities law rule that governs the trading and disclosure obligations of company insiders — typically officers, directors and large shareholders — to promote transparency and deter unfair profit-taking. It requires insiders to publicly report their stock trades and allows companies or the issuer to reclaim quick, short-term profits from certain insider trades, like a scoreboard and a refund policy that help investors see and limit possible insider advantage.
Rule 16a-13 regulatory
"a transaction exempt from Section 16 of the Exchange Act, pursuant to Rule 16a-13 thereunder"
weighted average price financial
"This price reflects the weighted average price for open-market sales of Shares on July 31, 2026"
Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.
dispositive power regulatory
"Mr. Robbins shares voting and dispositive power over the Shares held by the Glenview Investment Funds"
Dispositive power is the authority to decide the final outcome of an asset, legal claim, contract, or corporate action — in effect the power to dispose of or resolve something. For investors it matters because whoever holds that authority can determine who gets paid, who controls an asset or vote, and how risks and returns are allocated; think of it like holding the key that lets you lock in the winner or loser in a deal.
beneficially own regulatory
"Mr. Robbins shares voting and dispositive power and may be deemed to beneficially own such Shares"
Beneficially own means having the economic rights and risks of a security—such as the right to receive dividends, sell the shares, or profit from price changes—whether or not your name appears on the official share register. Think of it like renting a car: you use it and reap the benefits even if the title lists someone else. Investors care because beneficial ownership determines who truly controls value, must be disclosed under securities rules, and can signal potential influence or trading activity that affects a stock’s price.
pecuniary interest financial
"disclaims beneficial ownership over any securities owned other than to the extent of any pecuniary interest"
