What are performance share units (PSUs)?

Performance Share Units (PSUs) are a form of deferred compensation offered by companies, particularly to senior employees or key talent. They are equity-based, meaning their value is linked to the company's stock performance.

Unlike simpler forms of stock options, PSUs come with a crucial condition: they only vest, or become yours to claim, if the company achieves specific, pre-defined performance metrics within a set timeframe.¹

This dual requirement of continued employment and company success ensures that employees are incentivised to contribute directly to the company's growth and profitability. It's a way for organisations to align their most valuable people with their most important strategic objectives.

How performance share units work

The mechanics of PSUs involve a structured process from grant to potential payout. Understanding these steps is vital to managing your expectations and financial planning.

Granting PSUs and setting performance goals

When a company decides to award PSUs, it first outlines the specific terms. This includes the number of units granted to the employee and, critically, the performance goals that must be met.

These goals are usually tied to the company's strategic objectives. They can range from financial targets like revenue growth or profit margins to operational achievements like market share expansion.

The clarity and measurability of these goals are paramount. They determine whether the PSUs will ultimately translate into tangible value for the employee.

Understanding PSU vesting schedules

Vesting refers to the period you must remain employed by the company and the time it takes for the performance conditions to be met before you can claim your PSUs.

Common vesting structures include cliff vesting, where all units vest at a single point in time after a minimum period, and graded vesting, where portions of the PSUs vest incrementally over several years.²

The vesting schedule is designed to encourage long-term commitment and reward sustained performance. It's a crucial detail to note in your compensation agreement.

Performance metrics that drive PSU value

The value of your PSUs hinges on the company's ability to hit specific performance targets. These metrics are the engine that drives the worth of your award.

Common examples in the UK include achieving a certain percentage of revenue growth year-on-year, maintaining or increasing profit margins, or improving earnings per share (EPS).

Other metrics might involve increasing market share, achieving customer satisfaction targets, or meeting environmental, social, and governance (ESG) objectives, reflecting a broader commitment to corporate responsibility.

What is a PSU stock and how is it settled?

When your PSUs vest, you receive their value. This settlement can take one of two primary forms, depending on the company's policy.¹

Receiving PSU stock

In some cases, upon vesting, you will be issued actual shares of the company's stock. This means you become a shareholder, owning a piece of the company.

This can be an attractive outcome, especially if you believe in the company's future growth prospects and wish to hold onto the shares for further appreciation.

Cash settlement of PSUs

Alternatively, many companies opt for cash settlement. In this scenario, you receive the monetary value of your vested PSUs, typically based on the company's share price at the time of vesting.

This provides immediate liquidity. It's a straightforward way to realise the financial benefit of your performance, without the need to manage company shares directly.

PSU compensation and your financial future in the UK

PSUs represent a significant component of your overall remuneration package. Understanding their place in your financial planning is crucial for making informed career decisions.

PSU compensation explained

PSU compensation is a form of incentive pay designed to reward high performance. It's distinct from your base salary, annual bonus, or other benefits, as it's directly tied to the company's success.

It acts as a long-term incentive, encouraging you to stay with the company and contribute to its strategic goals, as your personal financial gain is linked to collective achievements.

The impact of PSU compensation on your career

Receiving PSUs can be a strong indicator of your value to the company and often signifies a role with significant responsibility. It can foster a sense of ownership and deeper engagement.

This can influence your career trajectory, aligning your personal financial aspirations with the company's long-term vision and success. It's a powerful tool for fostering loyalty and rewarding critical contributions.

Performance stock units taxation in the UK

Navigating the tax implications of PSUs in the UK is essential. Understanding when and how taxes apply will help you manage your finances effectively and avoid unexpected liabilities.

Understanding performance stock units taxation

In the UK, PSUs are generally treated as employment income - but only when they vest, not when they are granted.

The specific tax treatment can depend on the exact structure of the award and how it is settled. It’s always wise to consult with a tax professional for personalised advice.

Tax on vesting performance share units

When your PSUs vest and are settled, the value received is typically subject to Income Tax and National Insurance Contributions (NICs).³ This is usually calculated based on the market value of the shares or the cash received at the point of vesting.

The company awarding the PSUs will typically deduct these taxes at source, similar to how PAYE works for your salary.

Taxation of PSU stock gains

If you receive actual company shares upon vesting and decide to hold onto them, any profit you make when you eventually sell them may be subject to Capital Gains Tax (CGT).³

The CGT is levied on the increase in value of the shares from the time they vested to the time you sell them. Understanding the CGT allowance is important for managing this potential tax liability.

Exercising PSU stock

Unlike traditional stock options, where you typically pay an "exercise price" to purchase the shares, PSUs generally do not require an exercise purchase price.³

The value of PSUs is realised based on meeting performance and service conditions, not on paying to acquire the right to buy shares. Once vested, they are typically settled directly as shares or cash.

FAQs

What is the difference between a PSU and an RSU?

The main difference lies in the vesting conditions. Restricted Stock Units (RSUs) typically vest based solely on continued employment over a set period. Performance Share Units (PSUs), however, require both continued employment and the achievement of specific company performance targets to vest.¹

Can I lose my Performance Share Units?

Yes, you can forfeit your PSUs. This typically happens if you leave the company before the vesting period is complete, or if the company fails to meet the pre-defined performance metrics by the specified deadline.

What are the typical performance metrics for PSUs in UK companies?

Typical metrics include financial targets such as revenue growth, profit margins, or earnings per share (EPS). They can also include operational goals like increasing market share, or strategic objectives related to customer satisfaction or ESG performance.

How are PSUs valued for tax purposes in the UK?

For UK tax purposes, PSUs are usually valued based on their market value at the time they vest. This value is then typically treated as employment income, subject to Income Tax and National Insurance contributions.

What happens to my PSUs if I leave my job before they vest?

If you leave your job before your PSUs have vested, you will generally forfeit any unvested units. The specific terms will be detailed in your grant agreement, but it's common practice for unvested awards to be cancelled upon termination of employment.
