Key Takeaways
- Scope: any company preparing GAAP financial statements that grants equity to employees or non-employees.
- Measurement: awards are measured at grant-date fair value, usually with Black-Scholes-Merton for plain options.
- Recognition: expense is spread over the service period, straight-line or graded, depending on policy and award terms.
- Performance conditions: expense is recognized only when achievement is probable; IPO and sale conditions wait until the event.
- Link to 409A: the 409A common stock value feeds the ASC 718 model, so the two must line up.
- Audit focus: grant dates, assumptions, forfeitures, modifications and disclosures are where auditors look first.

Why ASC 718 Reporting Matters
Stock compensation is often one of the largest non-cash expenses in a startup’s income statement, and one of the most technical. Three areas make it important to get right.
GAAP Compliance
An accurate ASC 718 expense report is required for GAAP financial statements. Stock-based compensation has economic value and must be reflected in the income statement over the appropriate service period.
Audit Readiness
- Grant approval dates
- 409A valuation dates
- Exercise prices
- Vesting schedules
- Forfeiture treatment
- Valuation assumptions
- Modifications and repricings
- Expense recognition method
- Required financial statement disclosures
IRS and Tax Considerations
ASC 718 is a financial accounting standard, while Section 409A is a tax rule. They are different, but they often intersect.
A 409A valuation determines the fair market value of a private company’s common stock, which is usually used to set the exercise price for stock options. ASC 718 then uses that share value as an input to calculate the grant-date fair value of the award.
If the exercise price is below fair market value, employees can face tax on the spread as options vest, plus a 20% additional tax and interest. Keeping 409A valuation work and ASC 718 reporting aligned reduces risk for both the company and award holders.
ASC 718 vs. Section 409A at a Glance
| ASC 718 | Section 409A | |
|---|---|---|
| What it is | A GAAP accounting standard | A US tax rule on deferred compensation |
| Main question | How much compensation expense to record, and when | Whether the option exercise price is at least fair market value |
| Value measured | Fair value of the award (the option itself) | Fair market value of the underlying common stock |
| Who relies on it | Auditors, investors, lenders | The IRS and option holders |
| Consequence of errors | Misstated financial statements, audit adjustments | Tax on the spread at vesting, a 20% additional tax and interest for employees |
| How they connect | Uses the common stock value as the current share price input | Supplies that common stock value |

Acceptable Valuation Methods for ASC 718
ASC 718 requires companies to measure equity awards at grant-date fair value. For stock options, that usually means using an option-pricing model.
The right model depends on the award type, vesting terms, exercise behavior and the complexity of the equity plan. For many private companies, the Black-Scholes-Merton model is the most common choice. More complex awards may need a binomial or lattice model, or a Monte Carlo simulation.

Black-Scholes-Merton Model
The Black-Scholes-Merton model is widely used because it is relatively simple and well understood by auditors. It works best for standard stock options with time-based vesting and no unusual performance or market conditions. Most startups and private companies use it for ISOs and NSOs when the award structure is simple.
Monte Carlo Simulation
Monte Carlo simulations are typically used for awards with market conditions. For example, an award may vest only if the company’s stock price reaches a target or outperforms a market index. Because the model runs thousands of possible outcomes, it can estimate the fair value of awards with uncertain, market-driven terms. It requires specialized expertise and careful documentation.
Key Inputs to the Option-Pricing Model
The accuracy of an ASC 718 expense report depends heavily on the inputs. Even with the right model, weak assumptions lead to incorrect expense. For the Black-Scholes model, the key inputs are:
Current Share Price
The fair value of the underlying common stock on the grant date. Private companies typically use their most recent 409A valuation, provided nothing material has changed since its valuation date.
Exercise Price
The strike price set at grant, usually equal to the 409A fair market value.
Expected Term
The period the option is expected to remain outstanding until it is exercised or cancelled after vesting. Private companies often use the simplified method when they lack enough exercise history.
Volatility
The expected fluctuation in the company’s share price. Because private company shares do not trade, companies usually use the volatility of comparable public companies or an appropriate industry index.
Risk-Free Rate
The yield on zero-coupon US Treasury securities with a term matching the expected term of the option.
Dividend Yield
The expected dividend payout over the option term. For most early-stage startups, this is zero.
Each input should be supported by clear documentation. Auditors want to understand not only which assumptions were used, but why they were reasonable at the grant date. The model’s output is the grant-date fair value of each option, which drives the expense.
Expense Recognition Mechanics
Once the fair value of an award is determined, the company recognizes compensation expense over the appropriate period. This is where many companies run into trouble, especially with different vesting schedules or performance terms. Recognition depends on the award’s vesting conditions and the attribution method.
Straight-Line vs. Graded Attribution
Straight-line attribution recognizes expense evenly over the total vesting period. For example, if an option grant vests over four years, the company recognizes a quarter of the total expense each year. Cumulative expense must always be at least equal to the portion of the award that has vested.
Graded attribution treats each vesting tranche as a separate award, which front-loads expense into the early years.
For awards with only service conditions, the company can choose either method as an accounting policy. Awards with performance conditions are generally attributed tranche by tranche. Whatever the choice, apply it consistently and document it.
Example: $40,000 Grant Vesting 25% a Year for Four Years
| Year | Straight-line expense | Graded expense |
|---|---|---|
| Year 1 | $10,000 | $20,833 |
| Year 2 | $10,000 | $10,833 |
| Year 3 | $10,000 | $5,833 |
| Year 4 | $10,000 | $2,500 |
| Total | $40,000 | $40,000 |
Under graded attribution, the first tranche is expensed over one year, the second over two years, and so on, which is why year one carries more than half the total.
Vesting Conditions
Vesting conditions determine when an employee earns the award. Under ASC 718, the type of condition affects how expense is measured and recognized.
Service-based vesting is the most common structure for private companies. The employee must provide service over a period of time. A typical example is four-year vesting with a one-year cliff: 25% vests after the first year, and the rest vests monthly or quarterly over the next three years. Expense is recognized over the service period.
Performance-based vesting depends on a company or individual milestone, such as a revenue target, a product launch, a financing round or an EBITDA threshold. Expense is recognized only when achievement becomes probable, and is reversed if it stops being probable. Conditions tied to an IPO or a change in control are generally not treated as probable until the event occurs, so expense for double-trigger RSUs is usually recognized at that point, with a catch-up for service already provided. Finance teams should revisit probability each reporting period and document changes.
Market-based vesting depends on the stock price or a market-related target. These awards usually need a Monte Carlo simulation. Unlike performance conditions, market conditions are built into the grant-date fair value, and expense is recognized over the service period even if the market condition is never met, as long as the employee provides the required service.
Accounting for Modifications, Repricings, and Forfeitures
Once the fair value of an award is determined, the company recognizes compensation expense over the appropriate period. This is where many companies run into trouble, especially with different vesting schedules or performance terms. Recognition depends on the award’s vesting conditions and the attribution method.
Modifications
A modification is any change to the terms or conditions of an existing award. Common examples:
- Reducing the exercise price
- Extending the option expiration date
- Accelerating vesting
- Changing performance conditions
- Converting one type of award into another
- Adjusting terms after termination, such as a longer post-termination exercise window
When an award is modified, the company generally compares the fair value of the award immediately before and after the change. If the modified award is worth more, the difference is recognized as incremental compensation expense. Auditors review this closely, so keep board approvals, employee communications, updated grant agreements and valuation support for every modification.
Repricings
A repricing lowers the exercise price of outstanding options, usually after the company’s value falls and options are underwater. It can help retention, but it creates incremental expense and needs legal, tax and board review. Under ASC 718, the incremental fair value from the repricing is measured and recorded.
Forfeitures
Forfeitures occur when employees leave before their awards vest. ASC 718 lets companies choose one of two policies:
- Estimate forfeitures up front: apply an expected forfeiture rate and adjust it as actual experience changes.
- Account for forfeitures as they occur: reverse previously recognized expense only when awards are actually forfeited.
Many private companies choose to account for forfeitures as they occur because it is simpler. The right choice depends on company size, turnover patterns and reporting needs.
ASC 718-10-50 Disclosure Requirements
ASC 718 does not stop at calculating expense. Companies must also include stock compensation disclosures in their financial statement footnotes, so investors, auditors and other readers can understand the plans and the assumptions behind the expense. A complete disclosure package typically includes:
- Description of the stock plan: general terms, eligible participants, award types and key vesting provisions.
- Summary of award activity: grants, exercises, forfeitures, expirations and awards outstanding.
- Compensation cost recognized: the stock-based compensation expense in the income statement.
- Unrecognized compensation cost: the remaining cost for unvested awards.
- Weighted-average recognition period: the period over which the unrecognized cost will be recognized.
- Weighted-average grant-date fair value: for awards granted during the period.
- Valuation assumptions: expected volatility, expected term, risk-free rate and dividend yield, and the method used to estimate them.
Well-prepared disclosures prevent audit delays and last-minute revisions during financial statement review. Nonpublic companies have somewhat lighter requirements than public companies, so confirm which items apply to you.
ASC 718 Reporting Workflow for Private Companies
Private companies often underestimate the time needed to prepare an ASC 718 report. It takes more than running a valuation model: clean equity data, legal documents, board records, accounting policy decisions and disclosure preparation. A practical workflow has four steps.
Step 1: Data Gathering
Collect and reconcile all relevant equity documents and data:
- Cap table
- Stock plan documents
- Board approvals
- Grant agreements
- 409A valuation reports
- Employee termination records
- Exercise history
- Forfeiture history
- Modification records
- Prior-year ASC 718 reports
Step 2: Model Selection and Calculation
Choose the right valuation model for each award type. For plain-vanilla options, Black-Scholes is usually appropriate; complex awards may need a lattice model or Monte Carlo simulation. Calculate grant-date fair value using supported assumptions that match the award terms and the company’s accounting policies.
Step 3: Journal Entries
Prepare the journal entries. For equity-classified awards, a typical stock compensation entry is:
- Debit stock-based compensation expense
- Credit additional paid-in capital
Awards classified as liabilities, such as cash-settled SARs, are credited to a liability instead and remeasured each reporting period. Timing and amounts depend on vesting terms, attribution method, forfeitures and any modifications.
Step 4: Deliverables
The final ASC 718 package should include:
- ASC 718 expense report
- Grant-level calculation detail
- Assumption support
- Journal entry support
- Rollforward schedules
- Footnote disclosure support
The goal is equity records that are complete and consistent. Differences between the cap table, board approvals and accounting records cause major audit issues. For year-end audits, start at least three to four weeks before fieldwork. Companies with several award types or historical cleanup need more time.
Common Pitfalls and Audit Issues
ASC 718 becomes difficult when equity records are incomplete or assumptions are poorly supported. Most issues are avoidable with the right process.
Using Mismatched Dates
Incorrect Expected Term Calculations
The expected term has a major effect on option value. Errors happen when companies apply the simplified method inconsistently, use the wrong vesting schedule or fail to separate tranches properly.
Missing Board Approvals
The grant date is generally the date all required approvals are complete and the employer and employee have a mutual understanding of the key terms. If board approvals are missing, late or inconsistent with grant records, grant dates may need to be revised and expense recalculated.
Ignoring Modifications
Companies sometimes change awards informally without treating the change as a modification. Extending an exercise window after termination may look administrative, but it can trigger modification accounting. Review every change to award terms for ASC 718 impact.
Weak Forfeiture Tracking
If employee departures are not updated in the equity system, expense can be overstated or understated. Track forfeitures and reconcile equity records with HR data regularly.
Spreadsheet Errors
Spreadsheets can work for a very small company with a simple cap table. As the company grows, formula errors, version control problems and manual entry mistakes lead to audit issues. For companies preparing for an audit, fundraising, an IPO or M&A diligence, a more structured process is usually worth it.

Practical Deliverables
Wrapping It Up
ASC 718 is one of the most important accounting requirements for companies that issue equity compensation. It affects GAAP compliance, audit readiness, tax alignment, investor diligence and the accuracy of your financial statements.
The standard can feel complex because it involves valuation models, accounting judgments, vesting conditions, forfeitures, modifications and detailed disclosures. With the right process and documentation, it becomes manageable.
For startups and private companies, the best approach is to address stock compensation accounting early, keep equity records clean, align 409A valuations with grant activity and prepare reports well before year-end pressure builds.
Frequently Asked Questions
1. What is ASC 718?
ASC 718 is the US GAAP standard for share-based payments. It requires companies to measure equity awards given to employees and non-employees at grant-date fair value and recognize that value as compensation expense over the period the award is earned.
2. What is the difference between ASC 718 and Section 409A?
Section 409A is a tax rule. For stock options, it matters because options granted with an exercise price at or above the fair market value of the common stock avoid 409A penalties, which is why private companies get 409A valuations. ASC 718 is a GAAP accounting standard that governs how companies measure and recognize compensation expense for equity awards. The 409A common stock value is often used as the share price input in the ASC 718 calculation.
3. Does a private company have to comply with ASC 718?
Yes. A private company that issues stock-based compensation and prepares GAAP financial statements must follow ASC 718. It matters most for companies being audited, raising institutional capital, preparing for an IPO or going through M&A due diligence. Private companies have some practical expedients, such as using a 409A-compliant valuation for the current share price and a simplified expected term.
4. How often should ASC 718 calculations be performed?
At least annually as part of year-end close for companies with annual GAAP financial statements. Companies that report quarterly to investors or lenders, are preparing for an IPO, or have a high volume of equity activity often calculate quarterly or monthly.
5. Can we use a spreadsheet for our ASC 718 expense report?
A spreadsheet can work for a very early-stage company with a simple equity structure and few grants. As award volume, vesting complexity and modifications grow, spreadsheets become harder to control, and auditors test them more closely for formula, input and version errors.
6. What is the simplified method for expected term?
The simplified method estimates the expected term of a stock option as the midpoint between the vesting date and the contractual expiration date. Private companies often use it when they do not have enough exercise history to support a company-specific estimate.
7. Straight-line or graded attribution: which should we use?
For awards with only service conditions and graded vesting, ASC 718 lets a company choose either method as an accounting policy, as long as cumulative expense is at least equal to the portion that has vested. Awards with performance conditions are generally attributed tranche by tranche. Apply the chosen policy consistently.
8. When do IPO or change-in-control vesting conditions get expensed?
Conditions tied to an IPO or a change in control are generally not considered probable until the event happens. Expense for awards that vest only on such an event, such as double-trigger RSUs, is usually recognized when the event occurs, with a catch-up for service already provided.
9. How does Countsure help with ASC 718 reporting?
Countsure prepares grant-date fair value calculations, expense schedules, journal entry support and footnote disclosure inputs, with the assumptions documented so your auditor can review them. Countsure also prepares 409A valuations, which keeps the share price input consistent with grant pricing.
