4 terms

beneficially owned regulatory

"Item 4. | Ownership (a) | Amount beneficially owned: 891082.00"

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.

shared dispositive power regulatory

"(iv) Shared power to dispose or to direct the disposition of: 891,082"

Schedule 13G regulatory

"Item 1. | (a) | Name of issuer: TRUSTCO BANK CORP"

A Schedule 13G is a formal document that investors file with the government when they acquire a large ownership stake in a company, usually for investment purposes rather than control. It helps keep the public informed about who owns significant parts of a company's shares, which can influence how the company is managed and how investors make decisions. Filing this schedule is important for transparency and understanding the ownership landscape of publicly traded companies.

investment adviser (IA) financial

"SSGA FUNDS MANAGEMENT, INC. (IA);STATE STREET GLOBAL ADVISORS EUROPE LIMITED (IA);"

An investment adviser (IA) is a person or firm that provides personalized guidance on buying, selling, or holding investments and often manages client portfolios for a fee. Investors should care because an IA has a legal duty to act in the client's best interest—think of them as a navigator who plans and steers your financial journey—so their advice, fee structure and potential conflicts can directly affect returns and financial risk.
