Rule 10b5-1 trading plan regulatory
"The transactions reported herein were made pursuant to a Rule 10b5-1 trading plan"
A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.
beneficially owned financial
"The number of common units beneficially owned by Ms. Frangou includes (i) 3,183,199 common units"
Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.
general partnership units financial
"the General Partner owns 622,296 general partnership units, representing an approximately 2.1% ownership"
weighted average purchase prices financial
"The prices reported above reflect the weighted average purchase prices on each such day"
