IFRS 2: Measuring Share Awards with Post-Vesting Lock-up Periods

Share-based payment arrangements are a cornerstone of modern employee compensation, aligning employee incentives with shareholder value. Under IFRS 2 Share-based Payment, companies must recognize the fair value of these awards as an expense. While many aspects of IFRS 2 can be complex, one particular nuance that often warrants closer attention is the measurement of awards that come with a 'lock-up' period *after* they have vested.

What is a Post-Vesting Lock-up Period?

A lock-up period, in this context, refers to a specified time frame following the vesting date during which the employee is restricted from selling or transferring their newly vested shares. Companies often implement these restrictions to further encourage long-term retention, foster a stronger sense of ownership, and align employee interests with sustained business performance beyond the initial vesting hurdles.

IFRS 2 Treatment: Vesting Conditions vs. Post-Vesting Restrictions

It's essential to distinguish lock-up periods from 'vesting conditions'. IFRS 2 categorizes conditions into service conditions (e.g., staying with the company for three years) and performance conditions (e.g., achieving specific revenue targets). These conditions dictate *whether* an award will vest and how many instruments will ultimately be issued. They impact the number of instruments expected to vest, and thus the cumulative expense recognised.

Post-vesting lock-up periods, however, are *not* vesting conditions. The shares have already vested; the employee legally owns them, even if their ability to dispose of them is temporarily constrained. IFRS 2 views these restrictions as a characteristic of the *equity instrument itself*, impacting its fair value.

Impact on Fair Value Measurement

Because a lock-up period restricts an employee's immediate access to the liquidity of their shares, the value of those shares is inherently lower than that of otherwise identical, freely tradable shares. Therefore, under IFRS 2, this reduced marketability must be reflected in the fair value measurement of the award at the grant date.

When determining the fair value of a share-based award subject to a post-vesting lock-up, the company cannot simply use the observable market price of its ordinary shares on the grant date. Instead, the fair value needs to be discounted to account for the illiquidity imposed by the lock-up. This typically involves using a valuation technique that incorporates the impact of this non-marketable feature.

Valuation methodologies might include option pricing models (like Black-Scholes, adjusted for illiquidity) or other models designed to estimate a discount for lack of marketability. The key is to quantify the economic cost of not being able to sell the shares for the specified period. This discounted fair value is then expensed over the vesting period, just like any other share-based payment.

It's important to note that once this fair value is determined at the grant date, it is fixed for expense recognition purposes. The subsequent expiry of the lock-up period does not trigger a reversal or adjustment of the expense already recognized. The initial measurement correctly captured the value of an instrument *with* that specific restriction at the grant date.

Conclusion

For finance professionals, accurately applying IFRS 2 to awards with post-vesting lock-up periods is crucial for proper financial reporting. By treating these restrictions as a determinant of the equity instrument's fair value at the grant date, companies ensure that their share-based payment expense truly reflects the economic cost of the compensation provided. This nuanced approach highlights the importance of expert actuarial valuation in navigating the complexities of IFRS 2.
