Key Terms

open market, indirect ownership, Defined Benefit Plan

3 terms

open market financial

"Sale in open market or private transaction"

An open market is a system where buying and selling of goods, services, or financial assets happen freely without restrictions or special controls. For investors, it means they can trade assets easily and quickly, which helps determine fair prices based on supply and demand. This environment encourages transparency and competition, making it easier to buy or sell with confidence.

indirect ownership financial

"Indirect ownership noted as By Roberto Herencia Inc. 401(k)"

Defined Benefit Plan financial

"Nature of ownership: By Roberto Herencia Inc. Defined Benefit Plan"

A defined benefit plan is a retirement program that guarantees workers a specific monthly payment after they retire, with the employer responsible for funding whatever is needed to meet that promise. Investors care because these plans create long-term payment obligations that can affect a company’s cash flow and balance sheet—similar to a homeowner having a fixed mortgage the household must cover regardless of income swings.
