Over the course of my career, I have participated in several employee share purchase plans. Most produced favourable outcomes, although lengthy holding periods sometimes reduced their flexibility.

For this week’s article, I will explain how these plans work, where they can add value, and which risks employees should consider before participating.

An employee share purchase plan allows you to buy shares in your employer, or its parent company, usually through regular payroll deductions and often at a discount to the market price. It offers an accessible way to own part of the company you work for, but it also ties more of your financial life to a single employer.

Employee share purchase plans vary by employer, so it is important to understand the details before participating (trust me, I learnt the hard way).

In a typical plan, the employee chooses how much to contribute within a range set by the company. The employer collects those contributions during an offering period and uses them to buy shares on a specified purchase date.

The purchase price may include a discount, and some plans offer a “lookback” that uses the lower of the share price at the start of the offering period or on the purchase date.

The most distinctive advantage of an employee share purchase plan is often its built-in discount. Buying below market value creates an immediate financial cushion, and selling soon after purchase may turn that discount into a strong short-term return.

A lookback can increase the benefit further: if the share price rises during the offering period, you may still buy at the lower starting price; if it falls, the purchase price may reset to the lower ending price.

Some employers also provide matching contributions or bonus shares for remaining invested, which can justify participating at least up to the matched amount.

Payroll deductions make saving automatic, while regular purchases spread your entry points over time and reduce the temptation to time the market.

If the plan has no minimum holding period, you may be able to sell soon after purchase and capture the discount rather than making a long-term bet on your employer’s share price.

The financial advantages of these plans are meaningful, but they are several drawbacks.

The first is concentration risk, which is significant. Your salary, bonus, career prospects, and pension contributions already depend on your employer. If part of your annual bonus is also paid in shares or deferred into equity, an employee share purchase plan can compound that exposure.

This exposure creates double dependency, meaning the same events that hurt the share price can reduce both your bonus and the value of the shares you already own.

It is also important to remember that promised value is not received value. A bonus quoted in currency, but delivered in shares, is worth that amount only on the day it is granted.

Unvested bonus equity can also create “golden handcuffs”, because the prospect of forfeiting some or all of it can keep you in an unsuitable role longer than is beneficial.

Many plans also include clawback provisions that allow the company to reduce or reclaim equity following restatements or misconduct findings, sometimes even after vesting.

Another risk is price movement between contribution and purchase. Without a lookback, you could contribute for months and then buy at a price well above where the shares trade by the time you can sell. Even with a discount, a sharp fall in the share price can erase the gain and leave you with a loss.

Holding periods and trading restrictions can create further difficulties. Some plans require you to hold shares for a minimum period, while blackout windows and insider-trading rules may prevent you from selling when you would like, even at public companies. In private companies, there may be no ready market at all.

The plan itself can change as well. Employers may amend, suspend, or end a plan, reduce its discount, or tighten its rules, so a benefit that looks valuable today is not guaranteed to last.

Lastly, familiarity can cloud judgment. Working at a company does not mean you can predict its share price, and loyalty or optimism can make it harder to assess risk objectively.

Before participating, consider whether the plan offers a discount, lookback, or employer match, as these features may justify contributing at least enough to earn the available benefit.

Make sure your financial foundation is sound first, with an adequate emergency fund and manageable debt. Assess how much of your wealth and income already depends on your employer, because greater concentration strengthens the case for selling shares regularly.

Contribute only an amount that your budget can comfortably absorb, and understand the offering periods, purchase dates, holding rules, withdrawal restrictions, and tax treatment (yes tax treatment, because it is based upon where the shares are listed, not where you live).

One common strategy is to sell soon after each purchase, capture the discount, and reinvest the proceeds in a broadly diversified portfolio. Another is to retain a modest long-term holding, provided the position remains small relative to total wealth. Whichever approach you choose, decide on an exit plan in advance and apply it consistently.

Overall, an employee share purchase plan can be a valuable benefit, offering a discount, possible matching contributions, and an easy way to build the habit of investing.

The main risk is allowing too much of your wealth to become tied to one employer, particularly when bonus equity adds to that exposure. Used carefully, the plan can help you capture valuable benefits while maintaining a diversified portfolio. The key is to understand the terms and protect your cashflow.
