What Is an Adjustable-Rate Mortgage (ARM)?

The term adjustable-rate mortgage (ARM) refers to a home loan with a variable interest rate. With an ARM, the initial interest rate is fixed for a period of time. After that, the interest rate applied on the outstanding balance resets periodically, at yearly or even monthly intervals.

ARMs are also called variable-rate mortgages or floating mortgages. The interest rate for ARMs is reset based on a benchmark or index, plus an additional spread called an ARM margin. The typical index that is used in ARMs has been the London Interbank Offered Rate (LIBOR).

Understanding Adjustable-Rate Mortgages (ARMs)

Mortgages allow homeowners to finance the purchase of a home or other piece of property. When you get a mortgage, you’ll need to repay the borrowed sum over a set number of years as well as pay the lender something extra to compensate them for their troubles and the likelihood that inflation will erode the value of the balance by the time the funds are reimbursed.

In most cases, you can choose the type of mortgage loan that best suits your needs. A fixed-rate mortgage comes with a fixed interest rate for the entirety of the loan. As such, your payments remain the same. An ARM, where the rate fluctuates based on market conditions. This means that you benefit from falling rates and also run the risk if rates increase.

There are two different periods to an ARM. One is the fixed period and the other is the adjusted period. Here’s how the two differ:

• Fixed Period: The interest rate doesn’t change during this period. It can range anywhere between the first five, seven, or 10 years of the loan. This is commonly known as the intro or teaser rate.
• Adjusted Period: This is the point at which the rate changes. Changes are made during this period based on the underlying benchmark, which fluctuates based on market conditions.

Another key characteristic of ARMs is whether they are conforming or nonconforming loans. Conforming loans are those that meet the standards of government-sponsored enterprises (GSEs) like Fannie Mae and Freddie Mac. They are packaged and sold off on the secondary market to investors. Nonconforming loans, on the other hand, aren’t up to the standards of these entities and aren’t sold as investments.

Rates are capped on ARMs. This means that there are limits on the highest possible rate a borrower must pay. Keep in mind, though, that your credit score plays an important role in determining how much you’ll pay. So, the better your score, the lower your rate.

Types of ARMs

ARMs generally come in three forms: Hybrid, interest-only (IO), and payment option. Here’s a quick breakdown of each.

Hybrid ARM

Hybrid ARMs offer a mix of a fixed- and adjustable-rate period. With this type of loan, the interest rate will be fixed at the beginning and then begin to float at a predetermined time.

This information is typically expressed in two numbers. In most cases, the first number indicates the length of time that the fixed rate is applied to the loan, while the second refers to the duration or adjustment frequency of the variable rate.

For example, a 2/28 ARM features a fixed rate for two years followed by a floating rate for the remaining 28 years. In comparison, a 5/1 ARM has a fixed rate for the first five years, followed by a variable rate that adjusts every year (as indicated by the number one after the slash). Likewise, a 5/5 ARM would start with a fixed rate for five years and then adjust every five years.

Interest-Only (I-O) ARM

It’s also possible to secure an interest-only (I-O) ARM, which essentially would mean only paying interest on the mortgage for a specific time frame—typically three to 10 years. Once this period expires, you are then required to pay both interest and the principal on the loan.

These types of plans appeal to those keen to spend less on their mortgage in the first few years so that they can free up funds for something else, such as purchasing furniture for their new home. Of course, this advantage comes at a cost: The longer the I-O period, the higher your payments will be when it ends.

Payment-Option ARM

A payment-option ARM is, as the name implies, an ARM with several payment options. These options typically include payments covering principal and interest, paying down just the interest, or paying a minimum amount that does not even cover the interest.

Opting to pay the minimum amount or just the interest might sound appealing. However, it’s worth remembering that you will have to pay the lender back everything by the date specified in the contract and that interest charges are higher when the principal isn’t getting paid off. If you persist with paying off little, then you’ll find your debt keeps growing—perhaps to unmanageable levels.

Advantages and Disadvantages of ARMs

Adjustable-rate mortgages come with many benefits and drawbacks. We’ve listed some of the most common ones below.

Advantages

The most obvious advantage is that a low rate, especially the intro or teaser rate, will save you money. Not only will your monthly payment be lower than most traditional fixed-rate mortgages, you may also be able to put more down toward your principal balance. Just ensure your lender doesn’t charge you a prepayment fee if you do.

ARMs are great for people who want to finance a short-term purchase, such as a starter home. Or you may want to borrow using an ARM to finance the purchase of a home that you intend to flip. This allows you to pay lower monthly payments until you decide to sell again.

More money in your pocket with an ARM also means you have more in your pocket to put toward savings or other goals, such as a vacation or a new car.

Unlike fixed-rate borrowers, you won’t have to make a trip to the bank or your lender to refinance when interest rates drop. That’s because you’re probably already getting the best deal available.

Disadvantages

One of the major cons of ARMs is that the interest rate will change. This means that if market conditions lead to a rate hike, you’ll end up spending more on your monthly mortgage payment. And that can put a dent in your monthly budget.

ARMs may offer you flexibility but they don’t provide you with any predictability as fixed-rate loans do. Borrowers with fixed-rate loans know what their payments will be throughout the life of the loan because the interest rate never changes. But because the rate changes with ARMs, you’ll have to keep juggling your budget with every rate change.

These mortgages can often be very complicated to understand, even for the most seasoned borrower. There are various features that come with these loans that you should be aware of before you sign your mortgage contracts, such as caps, indexes, and margins.

How the Variable Rate on ARMs Is Determined

At the end of the initial fixed-rate period, ARM interest rates will become variable (adjustable) and will fluctuate based on some reference interest rate (the ARM index) plus a set amount of interest above that index rate (the ARM margin). The ARM index is often a benchmark rate such as the prime rate, the LIBOR, the Secured Overnight Financing Rate (SOFR), or the rate on short-term U.S. Treasuries.

Although the index rate can change, the margin stays the same. For example, if the index is 5% and the margin is 2%, the interest rate on the mortgage adjusts to 7%. However, if the index is at only 2% the next time that the interest rate adjusts, the rate falls to 4% based on the loan’s 2% margin.

Adjustable-Rate Mortgage vs. Fixed Interest Mortgage

Unlike ARMs, traditional or fixed-rate mortgages carry the same interest rate for the life of the loan, which might be 10, 20, 30, or more years. They generally have higher interest rates at the outset than ARMs, which can make ARMs more attractive and affordable, at least in the short term. However, fixed-rate loans provide the assurance that the borrower’s rate will never shoot up to a point where loan payments may become unmanageable.

With a fixed-rate mortgage, monthly payments remain the same, although the amounts that go to pay interest or principal will change over time, according to the loan’s amortization schedule.

If interest rates in general fall, then homeowners with fixed-rate mortgages can refinance, paying off their old loan with one at a new, lower rate.

Is an ARM Right for You?

An ARM can be a smart financial choice if you are planning to keep the loan for a limited period of time and will be able to handle any rate increases in the meantime. Put simply, an adjustable-rate mortgage is well suited for the following types of borrowers:

• People who intend to hold the loan for a short period of time
• Individuals who expect to see a positive change in their income
• Anyone who can and will pay off the mortgage within a short time frame

In many cases, ARMs come with rate caps that limit how much the rate can rise at any given time or in total. Periodic rate caps limit how much the interest rate can change from one year to the next, while lifetime rate caps set limits on how much the interest rate can increase over the life of the loan.

Notably, some ARMs have payment caps that limit how much the monthly mortgage payment can increase, in dollar terms. That can lead to a problem called negative amortization if your monthly payments aren’t sufficient to cover the interest rate that your lender is changing. With negative amortization, the amount that you owe can continue to increase, even as you make the required monthly payments.

The Bottom Line

Borrowers have many options available to them when they want to finance the purchase of their home or another type of property. You can choose between a fixed-rate or adjustable-rate mortgage. While the former provides you with some predictability, ARMs offer lower interest rates for a certain period of time before they begin to fluctuate with market conditions. There are different types of ARMs to choose from and they have pros and cons. But keep in mind that these kinds of loans are better suited for certain kinds of borrowers, including those who intend to hold onto a property for the short term or if they intend to pay off the loan before the adjusted period begins. If you’re unsure, talk to a financial expert about your options.

What Is the Accounting Rate of Return (ARR)?

The accounting rate of return (ARR) is a formula that reflects the percentage rate of return expected on an investment or asset, compared to the initial investment’s cost. The ARR formula divides an asset’s average revenue by the company’s initial investment to derive the ratio or return that one may expect over the lifetime of an asset or project. ARR does not consider the time value of money or cash flows, which can be an integral part of maintaining a business.

Understanding the Accounting Rate of Return (ARR)

The accounting rate of return is a capital budgeting metric that’s useful if you want to calculate an investment’s profitability quickly. Businesses use ARR primarily to compare multiple projects to determine the expected rate of return of each project, or to help decide on an investment or an acquisition.

ARR factors in any possible annual expenses, including depreciation, associated with the project. Depreciation is a helpful accounting convention whereby the cost of a fixed asset is spread out, or expensed, annually during the useful life of the asset. This lets the company earn a profit from the asset right away, even in its first year of service.

The Formula for ARR

The formula for the accounting rate of return is as follows:

$ARR = \frac{Average\, Annual\, Profit}{Initial\, Investment}$ARR=InitialInvestmentAverageAnnualProfit​

How to Calculate the Accounting Rate of Return (ARR)

1. Calculate the annual net profit from the investment, which could include revenue minus any annual costs or expenses of implementing the project or investment.
2. If the investment is a fixed asset such as property, plant, and equipment (PP&E), subtract any depreciation expense from the annual revenue to achieve the annual net profit.
3. Divide the annual net profit by the initial cost of the asset or investment. The result of the calculation will yield a decimal. Multiply the result by 100 to show the percentage return as a whole number.

Example of the Accounting Rate of Return (ARR)

As an example, a business is considering a project that has an initial investment of $250,000 and forecasts that it would generate revenue for the next five years. Here’s how the company could calculate the ARR:

• Initial investment: $250,000
• Expected revenue per year: $70,000
• Time frame: 5 years
• ARR calculation: $70,000 (annual revenue) / $250,000 (initial cost)
• ARR = 0.28 or 28%

Accounting Rate of Return vs. Required Rate of Return

The ARR is the annual percentage return from an investment based on its initial outlay of cash. Another accounting tool, the required rate of return (RRR), also known as the hurdle rate, is the minimum return an investor would accept for an investment or project that compensates them for a given level of risk.

The RRR can vary between investors as they each have a different tolerance for risk. For example, a risk-averse investor likely would require a higher rate of return to compensate for any risk from the investment. It’s important to utilize multiple financial metrics including ARR and RRR to determine if an investment would be worthwhile based on your level of risk tolerance.

Advantages and Disadvantages of the Accounting Rate of Return (ARR)

Advantages

The accounting rate of return is a simple calculation that does not require complex math and is helpful in determining a project’s annual percentage rate of return. Through this, it allows managers to easily compare ARR to the minimum required return. For example, if the minimum required return of a project is 12% and ARR is 9%, a manager will know not to proceed with the project.

ARR comes in handy when investors or managers need to quickly compare the return of a project without needing to consider the time frame or payment schedule but rather just the profitability or lack thereof.

Disadvantages

Despite its advantages, ARR has its limitations. It doesn’t consider the time value of money. The time value of money is the concept that money available at the present time is worth more than an identical sum in the future because of its potential earning capacity.

In other words, two investments might yield uneven annual revenue streams. If one project returns more revenue in the early years and the other project returns revenue in the later years, ARR does not assign a higher value to the project that returns profits sooner, which could be reinvested to earn more money.

The accounting rate of return does not consider the increased risk of long-term projects and the increased uncertainty associated with long periods.

Also, ARR does not take into account the impact of cash flow timing. Let’s say an investor is considering a five-year investment with an initial cash outlay of $50,000, but the investment doesn’t yield any revenue until the fourth and fifth years.

In this case, the ARR calculation would not factor in the lack of cash flow in the first three years, while in reality, the investor would need to be able to withstand the first three years without any positive cash flow from the project.

The Bottom Line

The accounting rate of return (ARR) is a simple formula that allows investors and managers to determine the profitability of an asset or project. Because of its ease of use and determination of profitability, it is a handy tool in making decisions. However, the formula does not take into consideration the cash flows of an investment or project, the overall timeline of return, and other costs, which help determine the true value of an investment or project.

What Is Asymmetric Information?

Asymmetric information, also known as “information failure,” occurs when one party to an economic transaction possesses greater material knowledge than the other party. This typically manifests when the seller of a good or service possesses greater knowledge than the buyer; however, the reverse dynamic is also possible. Almost all economic transactions involve information asymmetries.

Understanding Asymmetric Information

Asymmetric information exists in certain deals with a seller and a buyer whereby one party is able to take advantage of another. This is usually the case in the sale of an item. For example, if a homeowner wanted to sell their house, they would have more information about the house than the buyer. They might know some floorboards are creaky, the home gets too cold in winter, or that the neighbors are too loud; information that the buyer would not know until after they purchased the house. The buyer, then, might feel they paid too much for the house or would not have purchased it at all if they had this information beforehand.

Asymmetric information can also be viewed as the specialization and division of knowledge, as applied to any economic trade. For example, doctors typically know more about medical practices than their patients. After all, physicians have extensive medical school educational backgrounds that their patients generally don’t have. This principle equally applies to architects, teachers, police officers, attorneys, engineers, fitness instructors, and other trained professionals. Asymmetric information, therefore, is most often beneficial to an economy and a society in increasing efficiency.

Advantages and Disadvantages of Asymmetric Information

Advantages

Asymmetric information isn’t necessarily a bad thing. In fact, growing asymmetrical information is the desired outcome of a healthy market economy. As workers strive to become increasingly specialized in their chosen fields, they become more productive, and can consequently provide greater value to workers in other fields.

For example, a stockbroker’s knowledge is more valuable to a non-investment professional, such as a farmer, who may be interested in confidently trading stocks to prepare for retirement. On the flip side, the stockbroker does not need to know how to grow crops or tend to livestock to feed themself, but rather can purchase the items from a grocery store that are provided by the farmer.

In each of their respective trades, both the farmer and the stockbroker hold superior knowledge over the other, but both benefit from the trade and the division of labor.

One alternative to ever-expanding asymmetric information is for workers to study all fields, rather than specialize in fields where they can provide the most value. However, this is an impractical solution, with high opportunity costs and potentially lower aggregate outputs, which would lower standards of living.

Disadvantages

In some circumstances, asymmetric information may have near fraudulent consequences, such as adverse selection, which describes a phenomenon where an insurance company encounters the probability of extreme loss due to a risk that was not divulged at the time of a policy’s sale.

For example, if the insured hides the fact that they’re a heavy smoker and frequently engage in dangerous recreational activities, this asymmetrical flow of information constitutes adverse selection and could raise insurance premiums for all customers, forcing the healthy to withdraw. The solution is for life insurance providers to perform thorough actuarial work and conduct detailed health screenings, and then charge different premiums to customers based on their honestly disclosed risk profiles.

Special Considerations

To prevent abuse of customers or clients by finance specialists, financial markets often rely on reputation mechanisms. Financial advisors and fund companies that prove to be the most honest and effective stewards of their clients’ assets tend to gain clients, while dishonest or ineffective agents tend to lose clients, face legal damages, or both.

What Is After-Hours Trading?

After-hours trading is securities trading that starts at 4 p.m. U.S. Eastern Time after the major U.S. stock exchanges close. The after-hours trading session can run as late as 8 p.m., though volume typically thins out much earlier in the session. Trading in the after hours is conducted through electronic communication networks (ECNs).

Understanding After-Hours Trading

Traders and investors engage in after-hours trading for a variety of reasons. They may prefer trading with fewer market participants or their schedules may require it. They may want to take positions as a result of news that breaks after the close of the stock exchange. Or, they may want to close out a position before they leave on vacation.

Generally, after-hours trading refers to trading that takes place after normal market hours and up until about 8 pm. Premarket trading refers to trading that takes place before the start of normal market hours, generally from 7 a.m. until 9:25 a.m. Together, after-hours trading and premarket trading are referred to as extended-hours trading.

The precise times of extended-hours trading can depend on the ECN an investor uses or the financial institution where they place their orders. For instance, Wells Fargo allows after-hours trading from 4:05 p.m. ET until just 5 p.m.

Electronic markets (or ECNs) used in after-hours trading automatically attempt to match up buy and sell orders. If they can do so, trades are completed. If they can’t, trades remain unfilled.

After-hours trading typically only allows limit orders to buy, sell, or short, although a particular brokerage may be less restrictive. No stop, stop-limit, or orders with special instructions (such as fill or kill or all or none) are accepted. Moreover, orders are normally only good for the after-hours trading session in which they’re placed.

The maximum share amount per order is 25,000.

Quotes provided are limited to those available through the electronic market used. Investors may have access to other participating ECNs but it isn’t guaranteed.

Volume

In after-hours trading, the trading volume for a stock may spike on the initial release of news but most of the time thins out as the session progresses. The growth of volume generally slows significantly by 6 p.m. So, there is a substantial risk that investors will be trading illiquid stocks after-hours. 

Price

Not only does volume sometimes come at a premium in the after-hours trading sessions, so does price. It is not unusual for the spreads to be wide in the after-hours. The spread is the difference between the bid and the ask prices. Due to fewer shares trading, the spread may be significantly wider than during the normal trading session.

Participation

If liquidity and prices weren’t enough to make after-hours trading risky, the lack of participants may do the trick. That’s why certain investors and institutions may choose not to participate in after-hours trading, regardless of news or events.

It’s quite possible for a stock to fall sharply in the after hours only to rise once the regular trading session resumes the next day at 9:30 a.m. Many big institutional investors have a certain view of price action during after-hours trading sessions and express that view with their trades once the regular market re-opens.

Since volume is thin and spreads are wide in after-hours trading, it is much easier to push prices higher or lower. Fewer shares and trades are needed to make a substantial impact on a stock’s price. That’s why after-hours orders usually are restricted to limit orders. If your brokerage doesn’t restrict them, consider them anyway as a means to protect yourself from unexpected price swings and order fills.
