How mutual funds work

Few people know, how mutual funds work. People hear this abbreviation for the first time, When do you start investing. Banks and investment companies offer to invest in mutual funds, but no one explains, how investment funds are structured, who benefits and who manages them. I work for a management company, which invests money for fund shareholders. I'll tell, what are mutual funds, what are their advantages and what are the risks. But I'm a person in some way interested, so take my words with skepticism. The conversation will be long and rather boring.
