Difficulty: Intermediate | Prerequisites: Understanding of share-based compensation basics (stock options, equity instruments), familiarity with ASC 718 concepts.
Share-based compensation is one of the core ways companies incentivise and retain employees, and it sits at the heart of intermediate financial accounting because of how it affects the income statement, balance sheet, and EPS calculations. This topic zooms in on two specific equity instruments: restricted stock units (RSUs) and restricted stock awards (RSAs). Understanding the difference matters because each has distinct accounting treatment under ASC 718, different tax implications for both employer and employee, and different behavioural effects on workforce retention. You should already be comfortable with the general concept of compensatory stock plans and the idea of a vesting period before tackling this material.
RSUs are generally preferred over RSAs because they tie compensation directly to ongoing company performance, giving employees a genuine ownership stake that motivates sustained effort. When an employee leaves before vesting (whether fired, retired, or deceased), unvested RSUs are typically forfeited and can be reissued, while retirement and death scenarios may trigger special treatment such as discretionary awards or recovery from legal heirs.
Restricted Stock Unit (RSU)
A promise by the employer to deliver shares of company stock (or their cash equivalent) to an employee at a future date, contingent on meeting vesting conditions. Think of it as an IOU for shares: the employee owns nothing until the RSU vests.
Restricted Stock Award (RSA)
An actual grant of company shares to an employee on the grant date, subject to restrictions (typically a vesting schedule). The employee holds the shares immediately but cannot sell or transfer them until the restrictions lapse. In simple terms, the employee is a shareholder from day one, but with handcuffs on the shares.
Vesting period
The span of time an employee must remain with the company (or meet performance targets) before the restricted stock or units become fully owned and unrestricted. If the employee leaves before this period ends, the unvested portion is typically forfeited.
Forfeiture
The loss of unvested equity compensation when an employee departs before meeting vesting conditions. The forfeited shares or units revert to the company and may be reissued to other employees.
Compensatory stock plan
Any arrangement under which a company issues equity instruments (options, restricted stock, performance shares) to employees as part of their compensation package. Also referred to as share-based compensation or equity compensation.
ASC 718 (Compensation, Stock Compensation)
The U.S. GAAP standard governing how companies measure and recognise the cost of share-based payment transactions, including RSUs and RSAs. In simple terms, this is the rulebook that tells accountants how to put a number on equity comp and where to record it.
Ownership incentive without immediate dilution: RSUs grant employees a future ownership stake, meaning they become partial owners only upon vesting. This aligns their interests with the company's long-term performance.
Performance-linked returns: Because the value of RSUs tracks the share price, employees benefit only when the company performs well. This creates a direct feedback loop: better performance leads to higher personal returns.
Retention mechanism: The deferred nature of RSUs encourages employees to stay through the vesting period to realise the full value of their compensation.
Avoids the "mission accomplished" effect: With outright awards (RSAs), there is a risk that employees feel they have already been rewarded and lose the drive to innovate. RSUs keep the incentive forward-looking.
Timing of ownership: RSAs grant shares immediately (with restrictions); RSUs deliver shares only at vesting.
Voting rights and dividends: RSA holders typically receive dividends and can vote from the grant date. RSU holders generally receive neither until vesting, though some plans offer dividend equivalents.
Risk to the employee: RSA holders bear downside risk from day one (the share price can fall). RSU holders have no capital at risk before vesting.
Tax treatment: RSAs can trigger a Section 83(b) election, allowing the employee to pay tax at the grant-date value. RSUs are taxed as ordinary income at vesting, with no 83(b) option.
Termination (fired): Unvested RSUs or RSAs are forfeited. The company reclaims the rights and may reissue them to other employees. No compensation expense is recorded for the forfeited portion (prior expense is reversed under ASC 718).
Retirement: The company can anticipate retirement timing and stop issuing new grants as the retirement date approaches. Some plans include provisions for accelerated vesting upon retirement. In lieu of additional stock, a retiring employee may receive a discretionary award recognising long service.
Death: Unvested shares are typically forfeited. The company contacts the employee's legal heirs to recover any restricted shares already held. Some plans include "death benefit" provisions that accelerate vesting for the estate.
Most large publicly traded companies (Apple, Google, Amazon) rely heavily on RSUs as their primary equity compensation tool, precisely because RSUs align employee incentives with shareholder returns without requiring employees to put up capital. In practice, a company's HR and finance teams work together to design vesting schedules (commonly four years with a one-year cliff) that balance retention goals against dilution and compensation expense.
Students often think RSU holders are shareholders from the grant date. They are not. RSU holders have no ownership rights until the units vest and shares are delivered.
Students sometimes confuse forfeiture with cancellation. Forfeiture is involuntary (the employee fails to meet vesting conditions); cancellation is a company-initiated action, and it has different accounting consequences.
A common error is believing that all equity compensation is taxed the same way. RSAs allow a Section 83(b) election; RSUs do not. This distinction matters for both personal tax planning questions and for understanding deferred tax assets on the employer's books.
Students occasionally assume that a retiring employee automatically keeps all unvested shares. In most plans, unvested equity is forfeited unless the plan specifically provides for accelerated vesting upon retirement.
Expect questions asking you to distinguish between RSUs and RSAs in terms of when compensation expense is recognised and how it is measured.
Be prepared to calculate total compensation expense over a vesting period and to handle forfeiture adjustments (reversing previously recognised expense when an employee departs before vesting).
Questions may ask what journal entries change when an employee is terminated, retires, or dies mid-vesting. Know the forfeiture entry.
The Section 83(b) election and its availability only for RSAs (not RSUs) is a commonly tested distinction.
True or False: An RSU holder can vote on corporate matters from the grant date. (False: only after vesting and share delivery.)
Fill in the blank: When an employee is fired before vesting, unvested RSUs are __________ and previously recognised compensation expense is __________. (Forfeited; reversed.)
True or False: Both RSAs and RSUs are eligible for a Section 83(b) election. (False: only RSAs.)
Fill in the blank: Under ASC 718, compensation expense for RSUs is measured at the __________ on the grant date and recognised over the __________. (Fair value; vesting period.)
True or False: RSA holders bear downside share-price risk from the grant date. (True.)
Q: A company grants 10,000 RSUs to an employee with a four-year cliff vesting schedule. The grant-date fair value is $25 per unit. What is the total compensation expense, and how is it recognised?
A: Total compensation expense is $250,000 (10,000 x $25). It is recognised on a straight-line basis over the four-year vesting period, so $62,500 per year.
Q: Explain the key difference between how RSUs and RSAs affect an employee's tax position at the grant date.
A: RSA recipients can file a Section 83(b) election to be taxed on the fair market value at the grant date (potentially at a lower value). RSU recipients cannot make this election; they are taxed as ordinary income when the units vest and shares are delivered.
Q: An employee holding unvested RSUs is terminated two years into a four-year vesting period. What accounting entry does the employer make?
A: The employer reverses any compensation expense previously recognised for that employee's RSUs. The debit goes to Additional Paid-in Capital (or the relevant equity account) and the credit to Compensation Expense.
Q: Why might a company prefer to grant RSUs rather than RSAs from a retention standpoint?
A: RSUs deliver value only upon vesting, which keeps the employee's financial incentive tied to staying and performing through the entire vesting period. RSAs grant shares upfront, which can reduce the forward-looking retention incentive once the employee already holds the stock.
Q: An employee dies one year into a three-year vesting period holding 5,000 unvested RSUs. Describe two possible outcomes depending on the plan's terms.
A: If the plan has no death-benefit provision, the RSUs are forfeited and the company reverses the related compensation expense. If the plan includes accelerated vesting upon death, the RSUs vest immediately, shares are delivered to the employee's estate, and the company recognises any remaining unrecognised compensation expense at that point.
This material connects directly to diluted earnings per share (EPS) calculations, because outstanding RSUs are included in the denominator using the treasury stock method. It also ties into deferred tax accounting: the compensation expense recognised under GAAP often differs from the tax deduction (which occurs at vesting for RSUs), creating temporary differences and deferred tax assets. If you are covering stock options elsewhere in the course, note that RSUs and options share the same ASC 718 framework but differ in measurement (options require an option-pricing model; RSUs are measured at the share price).
