What a year you had! You broke your leg right before your beach vacation (which you had to cancel), your sore tooth needed a crown, and your fender bender necessitated major car repairs. Luckily you had medical, dental, auto, and even trip insurance. The money you received in insurance claims was more than the total you paid in premiums this year. Thatās good, right?
If every person had a bad year like this, how would insurance companies stay in business? Insurance companies have to make sure the claims they pay out in total are covered by the premiums they collect from all their policyholders. This balance of premiums versus payouts is how insurance works.
Insurance is an agreement in which a person makes payments to a company and the company promises to pay out money if the person has a specific loss.
Depending on your situation, you might have some or all of the following types of insurance:
Insurance companies typically collect money from large groups of policyholders. They put all the money into one pool thatās used to make payouts. Because the group of policyholders is diverse, itās unlikely that everyone will have large claims at one time. In fact, a risk that is insurable must meet some requirements:
In order to be profitable, insurance companies use certain techniques to help mitigate the risk of losses:
Rather than pay a company to insure them, a self-insured person sets aside money to be used for a loss. For example, rather than buying life insurance, you might put aside money that would cover certain costs when you pass away. The risk is that your savings might not cover those costs.
Although the federal government has the authority to make sure that insurance companies donāt have misleading advertising or act as monopolies, most regulation is at the state level. States regulate in four areas:
Risk pooling is the process of combining different people into one group so that some people are at high risk and other people are at low risk of having a claim. For example, a health insurance risk pool would include healthy and less healthy people together to balance out the risk of claims outpacing premiums. The problem is that each side (insurer and insured) may have a vested interest in tipping the scales in their favor.
Adverse selection. If the insurance companies donāt have adequate information about their customers, in an attempt to pool the risk, they may end up with only higher-risk clients. This situation is called āadverse selection.ā An example of adverse selection would be when a person raises the insurable limit on a dental policy because they just cracked a tooth and know theyāll likely need a root canal and a crown soon. Another would be when a person whose cholesterol just went up increases the payout on a term life insurance policy. Adverse selection creates higher insurance costs. When only high-risk people have the insurance, they will likely file more claims, which uses up the money from premiums held by the insurance company. Rates must therefore be raised to cover the costs.
Cherry-picking. As a way to get around adverse selection, insurance companies may try to ācherry-pickā their customers. For example, they might try to insure only nonsmokers or young people or those with a clean driving record. Some auto insurers offer discounts to people who install safe-driving software on their phones. Some low-risk professions (such as the American Institute of Certified Public Accountants) offer life insurance only to their own members. In other cases, insurance companies raise prices or donāt even offer insurance to customers with very high risk, such as in hurricane zones in Florida or areas of California that are prone to wildfires.
Cherry-picking is seen by some as unethical, as it penalizes the most vulnerable people who actually need insurance. But on the other hand, for the customer with a very low risk of a claim, it seems unfair to pay for those who will be making significant claims. For example, residents in the Southeast who live inlandāhundreds of miles from the coastāwouldnāt want their premiums to reflect the same level of storm risk as those who live right on the Atlantic.
Before the Affordable Care Act, health insurance companies could deny coverage to those with preexisting conditions. But that left millions of people vulnerable to catastrophic risks. Federal regulation has ended that practice to make sure that all U.S. citizens are eligible for medical insurance. Still, insurance is always a balancing act between premiums and claims.
The first American insurance company was organized by Benjamin Franklin in 1752. Since then, insurance companies have tried to weather disasters ranging from the Great Chicago Fire in 1871 and the San Francisco earthquake of 1906 to Hurricane Katrina in 2005. Many insurance companies have gone under trying to pay out multiple simultaneous large claims.
By using underwriting, risk pooling, and investing their assets, as well as by following state regulations, insurance companies hope to be able to pay claims so that all insured customers are covered in case of loss.
If youāre at a high risk for a type of insurance, such as having cancer or having a poor driving record, expect to pay more for coverage. But it pays to shop around, as different companies may offer better values. Or become part of a group that will help spread the cost of insurance among other lower-risk customers.
If youāre one of those who pay premiums but rarely (or never) file claims, you may feel like you got the short end of the stick financially. But really, what you got was peace of mind. On the other side of the coin, someone may have paid a few thousand dollars in homeownerās insurance, then their house caught on fire, causing $100,000 in damages. Did that person really āwinā financially? No, not at all.
