Insurance companies earn investment profits on "float". Float, or available reserve, is the amount of money on hand at any given moment that an insurer has collected in insurance premiums but has not paid out in claims. Insurers start investing insurance premiums as soon as they are collected and continue to earn interest or other income on them until claims are paid out. The Association of British Insurers (gathering 400 insurance companies and 94% of UK insurance services) has almost 20% of the investments in the London Stock Exchange. In 2007, U.S. industry profits from float totaled $58 billion. In a 2009 letter to investors, Warren Buffett wrote, "we were paid $2.8 billion to hold our float in 2008."
In the 2018 midterm elections, ballot measures passed in both Missouri and Utah legalizing the use of medical marijuana. This means that in total, 32 states and Washington D.C. now allow for the medicinal use of cannabis. So can you use your health insurance to help pay for it? Due to the U.S. government's classification of the plant as a Schedule I drug, you can't use Medicare to pay for medical marijuana because it technically doesn't have any accepted medical use. Private insurers won’t cover it either, partially because the Food and Drug Administration hasn’t approved it for use. If you’re outside of the U.S. you’ll have more luck. With the legalization of recreational marijuana use in Canada in 2018, Sun Life Financial is now offering plans that cover medical marijuana use.
Insurers will often use insurance agents to initially market or underwrite their customers. Agents can be captive, meaning they write only for one company, or independent, meaning that they can issue policies from several companies. The existence and success of companies using insurance agents is likely due to improved and personalized service. Companies also use Broking firms, Banks and other corporate entities (like Self Help Groups, Microfinance Institutions, NGOs, etc.) to market their products.
One particular advantage of adding endorsements rather than seeking coverage through a separate insurer is that you have all of your coverages in one place. Furthermore, if you have, say, home and flood insurance with the same company and you need to file a home and flood claim, some insurers may only require a single deductible for coverage to kick in. Some endorsements that are indicative of a good homeowners insurance company are:
An entity which provides insurance is known as an insurer, insurance company, insurance carrier or underwriter. A person or entity who buys insurance is known as an insured or as a policyholder. The insurance transaction involves the insured assuming a guaranteed and known relatively small loss in the form of payment to the insurer in exchange for the insurer's promise to compensate the insured in the event of a covered loss. The loss may or may not be financial, but it must be reducible to financial terms, and usually involves something in which the insured has an insurable interest established by ownership, possession, or pre-existing relationship.
