They play a key role in preparing financial reports that help investors understand the company's financial health, much like a trusted navigator guiding a ship through complex waters. Their work ensures transparency and trust in the company's financial information.

"initial statement of beneficial ownership"

Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name.
