ESOP guide — How stock option programs work

This ESOP (Employee Stock Ownership Plan) guide examines the main forms of options, their characteristics and practical application. Classic options are financial instruments that grant the right, but not the obligation, to purchase or sell an underlying asset at a fixed price within a specified time period. However, in technology companies, options are widely used as a tool for management motivation, attracting investment and structuring transactions.

Main forms of option programs

Modern corporate practice uses several main forms of option programs, each with its own characteristics and advantages:

Standard stock options (ISO/NSO)

Standard stock options grant the right to acquire a specific number of company shares at a predetermined price (strike price) within a specified time period. The process of exercising the right to purchase shares is called option exercise. Standard options are typically granted with a vesting schedule, which determines when exactly the employee gains the right to exercise the option.

Standard options are divided into two main types:

Option typeISONSO
Employee investment$10,000 (1000 × $10)$10,000 (1000 × $10)
Sale proceeds$50,000 (1000 × $50)$50,000 (1000 × $50)
Profit$40,000$40,000
Tax$8,000 (20% of profit)*$14,800 (37% of profit)**
Net profit$32,000$25,200
Effective profit+320% on investment+252% on investment

Restricted Stock Units (RSU)

RSU represent a company's promise to grant an employee a specific number of shares after meeting certain conditions, usually related to length of employment or achievement of specific performance metrics. Unlike standard options, RSU do not require the employee to pay for shares upon receipt.

RSU represent a gratuitous right to receive shares upon expiration of the vesting period, without the need to purchase them. Upon vesting, the employee automatically receives shares and is taxed on their full market value.


The main tax optimization strategy for RSU holders is long-term share ownership after vesting to obtain the preferential capital gains tax rate (0-20%) under§1(h) of the U.S. Tax Code. When selling shares a year or more after vesting, any additional increase in value will be taxed at the preferential long-term capital gains rate in accordance with§1222(3) of the U.S. Tax Codeinstead of ordinary income tax under§1 of the U.S. Tax Code.

Phantom Stock Options

Phantom options represent a form of cash compensation whose amount is tied to the company's share value but does not involve actual share transfer. This instrument allows motivating employees without diluting the stake of existing shareholders.

  • No actual share transfer — the employee does not become a company shareholder
  • Taxation as ordinary income — the entire payment amount is subject to personal income tax if structured to an individual
  • Possible application in private companies without the need to determine actual market share value
  • Does not require issuing additional shares — preserves control of company capital

Stock Appreciation Rights (SAR)

SAR are similar to phantom options but grant the right to receive cash compensation equal to the difference between the current share value and the option exercise price. Like phantom options, SAR do not involve actual share transfer.

  • Option holder does not pay exercise price — unlike standard options
  • Preservation of share capital structure — no dilution of existing shareholders' stakes occurs
  • Administrative simplicity — actual share transfer not required

For SAR, tax burden is reduced by structuring the option through a holding company. With this approach, the holding company, rather than an individual, becomes the recipient of SAR payments, which allows applying corporate tax benefits and potentially reducing the effective tax rate.

Restricted Stock Awards (RSA)

RSA (Restricted Stock Awards) represent a reverse vesting mechanism whereby the employee receives all shares immediately upon grant, but with restrictions on their disposal. Unlike RSU, with RSA the option holder immediately becomes a full shareholder, however the shares remain "frozen" until certain conditions are met.

  • Immediate shareholder status — including voting rights and right to dividends
  • Reverse vesting mechanism — shares return to the company if KPI not achieved or upon leaving the company
  • Risk of losing shares if vesting conditions not met — the company can repurchase shares
  • Possible need to pay for shares upon receipt — though often this is nominal value

Employee Stock Purchase Plans (ESPP)

ESPP allow employees to purchase company shares at a discount from market price through regular payroll deductions. This is a popular instrument in public companies.


What is Qualified Small Business Stock (QSBS)?

Qualified Small Business Stock (QSBS) are shares of qualified small businesses under Section 1202 of the U.S. Tax Code. This program offers substantial tax advantages for investors and founders when certain conditions are met.

Qualification criteria:

The main advantage of QSBS is 100% capital gains exclusion for shares acquired after September 27, 2010. To receive this benefit, several conditions must be met: minimum holding period for shares is 5 years, shares must be acquired at original issuance for cash, property or as compensation for services.

What is 83(b) Election?

83(b) Election is a U.S. tax benefit for holders of restricted stock, allowing them to pay tax upon receipt of shares rather than upon removal of restrictions (vesting).

Main characteristics:

The main advantage of 83(b) Election is the ability to minimize tax obligations, especially when share value at receipt is low and significant growth is expected. The risk is that if share value falls or the company fails, the tax paid is not refunded.

What is Founders Stock?

Founders Stock is a special type of shares issued to company founders in early stages of business development. Distinguished by low initial value and often have special rights and restrictions.

Main characteristics:

Founders typically file an 83(b) Election when receiving shares with vesting to minimize tax obligations. This allows paying tax on the low initial share value rather than on their increased value at vesting.

What is Fair Price?

The Fair Price concept plays a key role in setting option exercise price. Under Section 409A of the U.S. Tax Code, the exercise price must not be below the fair market value (FMV) of shares at the time of option grant.

For private companies, an independent valuation (409A valuation) is required.Main valuation methodologies include:

  • Comparable Company Analysis — comparison with public companies in the same industry
  • Discounted cash flows (DCF) — calculation of present value of future income
  • Prior financing round data — reference to recent investments
  • Black-Scholes model — mathematical calculation of option value
  • Net asset method — valuation of assets minus liabilities

An independent 409A valuation is typically valid for 12 months or until material changes in the business (new financing round, significant change in financial metrics). Most companies conduct valuations annually or after each investment round.
