What Is an Abnormal Return?

An abnormal return describes the unusually large profits or losses generated by a given investment or portfolio over a specified period. The performance diverges from the investments’ expected, or anticipated, rate of return (RoR)—the estimated risk-adjusted return based on an asset pricing model, or using a long-run historical average or multiple valuation techniques.

Returns that are abnormal may simply be anomalous or they may point to something more nefarious such as fraud or manipulation. Abnormal returns should not be confused with “alpha” or excess returns earned by actively managed investments.

Understanding Abnormal Returns

Abnormal returns are essential in determining a security or portfolio’s risk-adjusted performance when compared to the overall market or a benchmark index. Abnormal returns could help to identify a portfolio manager’s skill on a risk-adjusted basis. It will also illustrate whether investors received adequate compensation for the amount of investment risk assumed.

An abnormal return can be either positive or negative. The figure is merely a summary of how the actual returns differ from the predicted yield. For example, earning 30% in a mutual fund that is expected to average 10% per year would create a positive abnormal return of 20%. If, on the other hand, in this same example, the actual return was 5%, this would generate a negative abnormal return of 5%.

Cumulative Abnormal Return (CAR)

Cumulative abnormal return (CAR) is the total of all abnormal returns. Usually, the calculation of cumulative abnormal return happens over a small window of time, often only days. This short duration is because evidence has shown that compounding daily abnormal returns can create bias in the results.

Cumulative abnormal return (CAR) is used to measure the effect lawsuits, buyouts, and other events have on stock prices and is also useful for determining the accuracy of asset pricing models in predicting the expected performance.

The capital asset pricing model (CAPM) is a framework used to calculate a security or portfolio’s expected return based on the risk-free rate of return, beta, and the expected market return. After the calculation of a security or portfolio’s expected return, the estimate for the abnormal return is calculated by subtracting the expected return from the realized return.

Example of Abnormal Returns

An investor holds a portfolio of securities and wishes to calculate the portfolio’s abnormal return during the previous year. Assume that the risk-free rate of return is 2% and the benchmark index has an expected return of 15%.

The investor’s portfolio returned 25% and had a beta of 1.25 when measured against the benchmark index. Therefore, given the amount of risk assumed, the portfolio should have returned 18.25%, or (2% + 1.25 x (15% – 2%)). Consequently, the abnormal return during the previous year was 6.75% or 25 – 18.25%.

The same calculations can be helpful for a stock holding. For example, stock ABC returned 9% and had a beta of 2, when measured against its benchmark index. Consider that the risk-free rate of return is 5% and the benchmark index has an expected return of 12%. Based on the CAPM, stock ABC has an expected return of 19%. Therefore, stock ABC had an abnormal return of -10% and underperformed the market during this period.

What Is Accounting?

Accounting is the process of recording financial transactions pertaining to a business. The accounting process includes summarizing, analyzing, and reporting these transactions to oversight agencies, regulators, and tax collection entities. The financial statements used in accounting are a concise summary of financial transactions over an accounting period, summarizing a company’s operations, financial position, and cash flows. 

How Accounting Works

Accounting is one of the key functions of almost any business. It may be handled by a bookkeeper or an accountant at a small firm, or by sizable finance departments with dozens of employees at larger companies. The reports generated by various streams of accounting, such as cost accounting and managerial accounting, are invaluable in helping management make informed business decisions. 

The financial statements that summarize a large company’s operations, financial position, and cash flows over a particular period are concise and consolidated reports based on thousands of individual financial transactions. As a result, all professional accounting designations are the culmination of years of study and rigorous examinations combined with a minimum number of years of practical accounting experience.

History of Accounting

The history of accounting has been around almost as long as money itself. Accounting history dates back to ancient civilizations in Mesopotamia, Egypt, and Babylon. For example, during the Roman Empire, the government had detailed records of its finances. However, modern accounting as a profession has only been around since the early 19th century.

Luca Pacioli is considered “The Father of Accounting and Bookkeeping” due to his contributions to the development of accounting as a profession. An Italian mathematician and friend of Leonardo da Vinci, Pacioli published a book on the double-entry system of bookkeeping in 1494.

By 1880, the modern profession of accounting was fully formed and recognized by the Institute of Chartered Accountants in England and Wales. This institute created many of the systems by which accountants practice today. The formation of the institute occurred in large part due to the Industrial Revolution. Merchants not only needed to track their records but sought to avoid bankruptcy as well.

Types of Accounting

Accountants may be tasked with recording specific transactions or working with specific sets of information. For this reason, there are several broad groups that most accountants can be grouped into.

Financial Accounting

Financial accounting refers to the processes used to generate interim and annual financial statements. The results of all financial transactions that occur during an accounting period are summarized in the balance sheet, income statement, and cash flow statement. The financial statements of most companies are audited annually by an external CPA firm.

For some, such as publicly-traded companies, audits are a legal requirement. However, lenders also typically require the results of an external audit annually as part of their debt covenants. Therefore, most companies will have annual audits for one reason or another.

Managerial Accounting 

Managerial accounting uses much of the same data as financial accounting, but it organizes and utilizes information in different ways. Namely, in managerial accounting, an accountant generates monthly or quarterly reports that a business’s management team can use to make decisions about how the business operates. Managerial accounting also encompasses many other facets of accounting, including budgeting, forecasting, and various financial analysis tools. Essentially, any information that may be useful to management falls underneath this umbrella.

Cost Accounting

Just as managerial accounting helps businesses make decisions about management, cost accounting helps businesses make decisions about costing. Essentially, cost accounting considers all of the costs related to producing a product. Analysts, managers, business owners, and accountants use this information to determine what their products should cost. In cost accounting, money is cast as an economic factor in production, whereas in financial accounting, money is considered to be a measure of a company’s economic performance.

Tax Accounting

While financial accountants often use one set of rules to report the financial position of a company, tax accountants often use a different set of rules. These rules are set at the federal, state, or local level based on what return is being filed. Tax accounts balance compliance with reporting rules while also attempting to minimize a company’s tax liability through thoughtful strategic decision-making. A tax accountant often oversees the entire tax process of a company: the strategic creation of the organization chart, the operations, the compliance, the reporting, and the remittance of tax liability.

The Accounting Profession

While basic accounting functions can be handled by a bookkeeper, advanced accounting is typically handled by qualified accountants who possess designations such as Certified Public Accountant (CPA) or Certified Management Accountant (CMA) in the United States.

In Canada, the three legacy designations—the Chartered Accountant (CA), Certified General Accountant (CGA), and Certified Management Accountant (CMA)—have been unified under the Chartered Professional Accountant (CPA) designation.

A major component of the accounting professional is the “Big Four”. These four largest accounting firms conduct audit, consulting, tax advisory, and other services. These firms, along with many other smaller firms, comprise the public accounting realm that generally advises financial and tax accounting.

Careers in accounting may vastly difference by industry, department, and niche. Some relevant job titles may include:

• Auditor (internal or external): ensures compliance with reporting requirements and safeguarding of company assets.
• Forensic Accountant: monitors internal or external activity to investigate the transactions of an individual or business.
• Tax Accountant: strategically plans the optimal business composition to minimize tax liabilities as well as ensures compliance with tax reporting.
• Managerial Accountant: analyzes financial transactions to make thoughtful, strategic recommendations often related to the manufacturing of goods.
• Information and Technology Analyst/Accountant: maintains the system and software in which accounting records are processed and stored.
• Controller: oversees the accounting functions of financial reporting, accounts payable, accounts receivable, and procurement.

The Accounting Rules

In most cases, accountants use generally accepted accounting principles (GAAP) when preparing financial statements in the U.S. GAAP is a set of standards and principles designed to improve the comparability and consistency of financial reporting across industries. Its standards are based on double-entry accounting, a method in which every accounting transaction is entered as both a debit and credit in two separate general ledger accounts that will roll up into the balance sheet and income statement.

In most other countries, a set of standards governed by the International Accounting Standards Board named the International Financial Reporting Standards (IFRS) is used.

Tax accountants overseeing returns in the United States rely on guidance from the Internal Revenue Service. Federal tax returns must comply with tax guidance outlined by the Internal Revenue Code (IRC). Tax accounts may also lean in on state or county taxes as outlined by the jurisdiction in which the business conducts business. Foreign companies must comply with tax guidance in the countries in which it must file a return.

Special Considerations

Accountants often leverage software to aid in their work. Some accounting software is considered better for small businesses such as QuickBooks, Quicken, FreshBooks, Xero, SlickPie, or Sage 50. Larger companies often have much more complex solutions to integrate with their specific reporting needs. This includes add-on modules or in-home software solutions. Large accounting solutions include Oracle, NetSuite, or Sage products.

The Accounting Cycle

Financial accountants typically operate in a cyclical environment with the same steps happening in order and repeating every reporting period. These steps are often referred to as the accounting cycle, the process of taking raw transaction information, entering it into an accounting system, and running relevant and accurate financial reports. The steps of the accounting cycle are:

1. Collect transaction information such as invoices, bank statements, receipts, payment requests, uncashed checks, credit card statements, or other mediums that may contain business transactions.
2. Post journal entries to the general ledger for the items in Step 1, reconciling to external documents whenever possible.
3. Prepare an unadjusted trial balance to ensure all debits and credits balance and material general ledger accounts look correct.
4. Post adjusting journal entries at the end of the period to reflect any changes to be made to the trial balance run in Step 3.
5. Prepare the adjusted trial balance to ensure these financial balances are materially correct and reasonable.
6. Prepare the financial statements to summarize all transactions for a given reporting period.

Cash Method vs. Accrual Method of Accounting

Financial accounts have two different sets of rules they can choose to follow. The first, the accrual basis method of accounting, has been discussed above. These rules are outlined by GAAP and IFRS, are required by public companies, and are mainly used by larger companies.

The second set of rules follow the cash basis method of accounting. Instead of recording a transaction when it occurs, the cash method stipulates a transaction should be recorded only when cash has exchanged. Because of the simplified manner of accounting, the cash method is often used by small businesses or entities that are not required to use the accrual method of accounting.

Imagine a company buys $1,000 of inventory on credit. Payment is due for the inventory in 30 days.

• Under the accrual method of accounting, a journal entry is recorded when the order is placed. The entry records a debit to inventory (asset) for $1,000 and a credit to accounts payable (liability) for $1,000. When 30 days has passed and the inventory is actually paid for, the company posts a second journal entry: a debit to accounts payable (liability) for $1,000 and a credit to cash (asset) for $1,000.
• Under the cash method of accounting, a journal entry is only recorded when cash has been exchanged for inventory. There is no entry when the order is placed; instead, the company enters only one journal entry at the time the inventory is paid for. The entry is a debit to inventory (asset) for $1,000 and a credit to cash (asset) for $1,000.

The difference between these two accounting methods is the treatment of accruals. Naturally, under the accrual method of accounting, accruals are required. Under the cash method, accruals are not required and not recorded.

Why Accounting Is Important

Accounting is a back-office function where employees may not directly interface with customers, product developers, or manufacturing. However, accounting plays a key role in the strategic planning, growth, and compliance requirements of a company.

• Accounting is necessary for company growth. Without insight into how a business is performing, it is impossible for a company to make smart financial decisions through forecasting. Without accounting, a company wouldn’t be able to tell which products are its best sellers, how much profit is made in each department, and what overhead costs are holding back profits.
• Accounting is necessary for funding. External investors want confidence that they know what they are investing in. Prior to private funding, investors will usually require financial statements (often audited) to gauge the overall health of a company. The same rules pertain to debt financing. Banks and other lending institutions will often require financial statements in compliance with accounting rules as part of the underwriting and review process for issuing a loan.
• Accounting is necessary for owner exit. Small companies that may be looking to be acquired often need to present financial statements as part of acquisition or merger efforts. Instead of simply closing a business, a business owner may attempt to “cash-out” of their position and receive compensation for building a company. The basis for valuing a company is to use its accounting records.
• Accounting is necessary to make payments. A company naturally incurs debt, and part of the responsibility of managing that debt is to make payments on time to the appropriate parties. Without positively fostering these business relationships, a company may find itself with a key supplier or vendor. Through accounting, a company can always know who it has debts to and when those debts are coming due.
• Accounting is necessary to collect payments. A company may agree to extend credit to its customers. Instead of collecting cash at the time of an agreement, it may give a customer trade credit terms such as net 30. Without accounting, a company may have a hard time keeping track of who owes it money and when that money is to be received.
• Accounting may be required. Public companies are required to issue periodic financial statements in compliance with GAAP or IFRS. Without these financial statements, a company may be de-listed from an exchange. Without proper tax accounting compliance, a company may receive fines or penalties.

Example of Accounting

To illustrate double-entry accounting, imagine a business sends an invoice to one of its clients. An accountant using the double-entry method records a debit to accounts receivables, which flows through to the balance sheet, and a credit to sales revenue, which flows through to the income statement.

When the client pays the invoice, the accountant credits accounts receivables and debits cash. Double-entry accounting is also called balancing the books, as all of the accounting entries are balanced against each other. If the entries aren’t balanced, the accountant knows there must be a mistake somewhere in the general ledger.

What Is an Accrued Expense?

An accrued expense, also known as accrued liabilities, is an accounting term that refers to an expense that is recognized on the books before it has been paid. The expense is recorded in the accounting period in which it is incurred.

Understanding Accrued Expenses

Since accrued expenses represent a company’s obligation to make future cash payments, they are shown on a company’s balance sheet as current liabilities. An accrued expense can be an estimate and differ from the supplier’s invoice that will arrive at a later date. Following the accrual method of accounting, expenses are recognized when they are incurred, not necessarily when they are paid.

An example of an accrued expense is when a company purchases supplies from a vendor but has not yet received an invoice for the purchase. Other forms of accrued expenses include interest payments on loans, warranties on products or services received, and taxes—all of which have been incurred or obtained, but for which no invoices have been received nor payments made. Employee commissions, wages, and bonuses are accrued in the period they occur although the actual payment is made in the following period.

Accrual vs. Cash Basis Accounting

Accrual accounting differs from cash basis accounting, which records financial events and transactions only when cash is exchanged—often resulting in the overstatement and understatement of income and account balances.

Although the accrual method of accounting is labor-intensive because it requires extensive journaling, it is a more accurate measure of a company’s transactions and events for each period. This more complete picture helps users of financial statements to better understand a company’s present financial health and predict its future financial position.

Accrued Expenses vs. Prepaid Expenses

Accrued expenses are the opposite of prepaid expenses. Prepaid expenses are payments made in advance for goods and services that are expected to be provided or used in the future. While accrued expenses represent liabilities, prepaid expenses are recognized as assets on the balance sheet. This is because the company is expected to receive future economic benefit from the prepayment.

On the other hand, an accrued expense is an event that has already occurred in which cash has not been a factor. Not only has the company already received the benefit, it still needs to remit payment. Therefore, it is literally the opposite of a prepayment; an accrual is the recognition of something that has already happened in which cash is yet to be settled.

Advantages and Disadvantages of Accrued Expenses

Advantages

Accrued expenses theoretically make a company’s financial statements more accurate. While the cash method is more simple, accrued expenses strive to include activity that may not have fully been incurred but will still happen. Consider an example where a company enters into a contract to incur consulting services. If the company receives an invoice for $5,000, accounting theory states the company should technically recognize this transaction because it is contractually obligated to pay for the service.

Accrued expenses also may make it easier for companies to plan and strategize. Accrued expenses often yield more consistent financial results as companies can include recurring transactions in their financial reports that may not yet have been paid. In addition, accrued expenses may be a financial reporting requirement depending on the company and their Securities and Exchange Commission filing requirements.

Disadvantages

Because of additional work of accruing expenses, this method of accounting is more time-consuming and demanding for staff to prepare. There is a greater chance of misstatements, especially is auto-reversing journal entries are not used. In addition, a company runs of the risk of accidently accruing an expense that they may have already paid.

Last, the accrual method of accounting blurs cash flow and cash usage as it includes non-cash transactions that have not yet impacted bank accounts. For a large company, the general ledger will be flooded with transactions that report items that have had no bearing on the company’s bank statement nor impact to the current amount of cash on hand.

Special Considerations

Reversing Entries

A critical component to accrued expenses is reversing entries, journal entries that back out a transaction in a subsequent period.

Accrued expenses are not meant to be permanent; they are meant to be temporary records that take the place of a true transaction in the short-term. Every accrued expense must have a reversing entry; without the reversing entry, a company risks duplicating transactions by recording both the actual invoice when it gets paid as well as the accrued expense.

Month-End/Year-End

Accrued expenses are prevalent during the end of an accounting period. A company often attempts to book as many actual invoices it can during an accounting period before closing its accounts payable ledger. Then, supporting accounting staff analyze what transactions/invoices might not have been recorded by the AP team and book accrued expenses.

For companies that are responsible for external reporting, accrued expenses play a big part in wrapping up month-end, quarter-end, or fiscal year-end processes. A company usually does not book accrued expenses during the month; instead, accrued expenses are booked during the close period.

Example of Accrued Expense

A company pays its employees’ salaries on the first day of the following month for services received in the prior month. So, employees that worked all of November will be paid in December. If on Dec. 31, the company’s income statement recognizes only the salary payments that have been made, the accrued expenses from the employees’ services for December will be omitted.

Because the company actually incurred 12 months’ worth of salary expenses, an adjusting journal entry is recorded at the end of the accounting period for the last month’s expense. The adjusting entry will be dated Dec. 31 and will have a debit to the salary expenses account on the income statement and a credit to the salaries payable account on the balance sheet.

When the company’s accounting department receives the bill for the total amount of salaries due, the accounts payable account is credited. Accounts payable is found in the current liabilities section of the balance sheet and represents the short-term liabilities of a company. After the debt has been paid off, the accounts payable account is debited and the cash account is credited.

The Bottom Line

Companies using the accrual method of accounting recognize accrued expenses, costs that have not yet been paid for but have already been incurred. Accrued expenses make a set of financial statements more consistent by recording charges in specific periods, though it takes more resources to perform this type of accounting. While the cash method of accounting recognizes items when they are paid, the accrual method recognizes accrued expenses based on when service is performed or received. 

What Is a AAA Credit Rating?

AAA is the highest possible rating that may be assigned to an issuer’s bonds by any of the major credit-rating agencies. AAA-rated bonds have a high degree of creditworthiness because their issuers are easily able to meet financial commitments and have the lowest risk of default.

Rating agencies Standard & Poor’s (S&P) and Fitch Ratings use the letters “AAA” to identify bonds with the highest credit quality, while Moody’s uses a slightly different “Aaa” to signify a bond’s top-tier credit rating.

Understanding AAA

Since AAA-rated bonds are perceived to have the lowest risk of default, these instruments tend to offer investors the lowest yields among bonds with similar maturity dates (lower risk = lower return). The term “default” refers to a bond issuer failing to fulfill its obligations, namely failing to make semiannual interest payments or repay the principal amount when due.

AAA ratings are given to government debt and companies’ corporate bonds. The global credit crisis of 2008 resulted in a number of companies losing their AAA rating, most notably General Electric (GE). As of September 2022, only two companies held the AAA rating outright: Microsoft (MSFT) and Johnson & Johnson (JNJ). Apple (AAPL) is split, with a Aaa rating by Moody’s and a AA+ (one notch below AAA) from S&P.

Even the United States suffered a ratings cut by S&P, to AA+ in 2012—losing its vaunted AAA status due to political infighting over raising the debt ceiling. Moody’s and Fitch maintained the U.S. at Aaa and AAA ratings, respectively.

Types of AAA Bonds

Municipal

Municipal bonds can be issued as either revenue bonds or general obligation bonds—with each type relying on different sources of income.

Revenue bonds, for example, are paid using fees and other specific income-generating sources, like city pools and sporting venues. On the other hand, general obligation bonds are backed by the issuer’s ability to raise capital through levying taxes. Pointedly: State bonds rely on state income taxes, while local school districts depend on property taxes.

Secured and Unsecured

Issuers can sell both secured and unsecured bonds. Each type of bond carries with it a different risk profile.

A secured bond means that a specific asset is pledged as collateral for the bond, and the creditor has a claim on the asset if the issuer defaults. Secured bonds may be collateralized with tangible items such as equipment, machinery, or real estate. Secured collateralized offerings may have a higher credit rating than unsecured bonds sold by the same issuer.

Conversely, unsecured bonds are simply backed by the issuer’s promise to pay. Therefore, the credit rating of such instruments relies heavily on the issuer’s income sources and business outlook.

Benefits of a AAA Rating

A high credit rating lowers the cost of borrowing for the issuer (or borrower). Therefore, it stands to reason that companies with high ratings are better positioned to borrow large sums of money than fixed-income instruments with lesser credit ratings. And a low cost of borrowing affords firms a substantial competitive advantage by letting them easily access credit to grow their businesses.

For example, a business may use the incoming funds from a new bond issue to launch a new product line, set up shop in a new location, or acquire a competitor. All of these initiatives can help a company increase its market share and thrive over the long haul.

The Bottom Line

Credit ratings are assigned to debt issues and bonds by the three major debt-rating agencies: S&P, Moody’s, and Fitch. Their credit ratings have a strong influence on the cost of borrowing for the issuer. The better the credit rating, the lower the cost to borrow.

AAA/Aaa ratings are the highest ratings issued by the credit-rating agencies and likely result in the lowest borrowing costs or yields. Investors seeking a better return should look down the credit-ratings scale for bond issuers with lower ratings and higher yields.
