Equity Compensation and Stock Options: Structuring Employee Ownership
Master equity compensation. Structure option pools, manage dilution, align team incentives.
Key Takeaways
- EMI options (Enterprise Management Incentives): UK tax-advantaged scheme for companies with <£30M gross assets. Employees pay no income tax on exercise (if exercised at or above grant price). Capital gains tax only on sale (currently 20%). Example: Grant 10,000 options at £1, exercise at £1, sell at £10 = £90K gain taxed at 20% = £18K tax. Without EMI: £90K taxed as income at 45% = £40.5K tax. Saving: £22.5K per employee.
- Option pool sizing: Standard is 10-15% of fully diluted shares reserved for employees. Series A: 10-15% pool (refreshed at each round). Series B: Additional 5-10%. Example: 10M shares outstanding, 15% pool = 1.5M options available. Allocation: CTO 1-2%, VP-level 0.5-1%, senior engineer 0.1-0.25%, mid-level 0.05-0.1%. Vesting: 4-year vesting with 1-year cliff (standard).
- Dilution management: Each funding round dilutes existing shareholders. Example: Pre-Series A founders own 100% (10M shares). Series A: Issue 3.3M new shares (25% to investors). Post-money: 13.3M shares, founders own 75%. Series B: Issue 4.4M shares (25% to investors). Post-money: 17.7M shares, founders own 56%. Track dilution per round and cumulative. Option pool comes from existing shareholders (pre-money) not new investors.
Structuring Equity Compensation for SaaS Teams
Designing option plans that attract talent and align incentives. **EMI options (UK tax-advantaged scheme)** Eligibility: Company requirements: - Gross assets under £30M - Fewer than 250 employees - Trading company (not investment company) - Must be independent (not subsidiary of large group) Employee requirements: - Must work at least 25 hours/week (or 75% of working time) - Cannot hold more than 30% of shares - Each employee can hold up to £250K worth of options (at grant) Tax treatment: At grant: - No tax (no income tax, no NI) - Must notify HMRC within 92 days of grant At exercise: - No income tax (if exercise price ≥ market value at grant) - No employer NI - Example: Grant at £1, exercise at £1 = no tax event At sale: - Capital gains tax on gain (sale price - exercise price) - Business Asset Disposal Relief may apply (10% rate on first £1M) - Example: Exercise at £1, sell at £10 = £9 gain per share - 10,000 shares × £9 = £90K gain - With BADR: £90K × 10% = £9K tax - Without BADR: £90K × 20% = £18K tax Comparison with unapproved options: Unapproved options: - Income tax on exercise (difference between market value and exercise price) - Employer NI on exercise (13.8%) - Then CGT on subsequent gain Example comparison (10,000 options, grant £1, exercise £1, sell at £10): EMI: - Exercise: £0 tax - Sale: £90K × 10% (BADR) = £9K tax - Total: £9K Unapproved: - Exercise: (£10 - £1) × 10,000 = £90K income - Income tax: £90K × 45% = £40.5K - Employer NI: £90K × 13.8% = £12.4K (company pays) - Total: £52.9K EMI saving: £43.9K per employee **Option pool design** Pool sizing by stage: Pre-seed/Seed: - Reserve: 10-15% of fully diluted shares - Typically for first 5-10 hires - Example: 10M shares, 1.5M in pool (15%) Series A: - Top up to 15% (or create fresh 10-15%) - Refresh pool as part of funding round - Example: Post-money 13.3M shares, 15% pool = 2M options Series B: - Additional 5-10% refresh - Example: Post-money 17.7M shares, 7% refresh = 1.24M new options Series C+: - 3-5% refresh per round - Pool gets harder to refresh (more dilutive) Allocation guidelines: C-suite (CTO, CFO, COO): - 1-3% each (founding CTO higher) - Example: CTO joining at Series A = 1.5-2% - On 13.3M shares: 2% = 266K options VP level: - 0.25-1% each - Example: VP Engineering at Series A = 0.5% - On 13.3M shares: 0.5% = 66.5K options Director level: - 0.1-0.25% each - Example: Director of Product = 0.15% - On 13.3M shares: 0.15% = 20K options Senior individual contributor: - 0.05-0.15% each - Example: Senior Engineer = 0.1% - On 13.3M shares: 0.1% = 13.3K options Mid-level: - 0.02-0.05% each - Example: Mid-level Engineer = 0.03% - On 13.3M shares: 0.03% = 4K options Junior: - 0.01-0.02% each - Example: Junior Developer = 0.01% - On 13.3M shares: 0.01% = 1.3K options **Vesting schedules** Standard vesting: 4-year vesting with 1-year cliff: - Year 1: 25% vests at 1-year anniversary (cliff) - Years 2-4: Monthly vesting (1/48 per month) - If leave before 1 year: 0 options vest Example: Grant: 48,000 options - Month 1-11: 0 vested - Month 12 (cliff): 12,000 vest (25%) - Month 13: 12,750 (another 750) - Month 24: 24,000 (50%) - Month 36: 36,000 (75%) - Month 48: 48,000 (100%) Alternative vesting: Back-weighted vesting: - Year 1: 10%, Year 2: 20%, Year 3: 30%, Year 4: 40% - Used by some large companies to retain talent longer Milestone-based vesting: - Vest on achievement of specific goals - Example: 25% on product launch, 25% on £1M ARR, etc. Acceleration clauses: Single trigger acceleration: - All options vest on change of control (acquisition) - Less common (investors dislike) Double trigger acceleration: - Options vest if: (1) Change of control AND (2) Employee terminated within 12 months - More common and investor-friendly - Protects employees from being fired post-acquisition **Dilution tracking** Cap table management: Pre-funding example: | Shareholder | Shares | % | |---|---|---| | Founder A | 5,000,000 | 50% | | Founder B | 3,000,000 | 30% | | Option pool | 2,000,000 | 20% | | Total | 10,000,000 | 100% | Post-Series A (25% to investors): | Shareholder | Shares | % | |---|---|---| | Founder A | 5,000,000 | 37.5% | | Founder B | 3,000,000 | 22.5% | | Option pool | 2,000,000 | 15.0% | | Series A investors | 3,333,333 | 25.0% | | Total | 13,333,333 | 100% | Post-Series B (25% to new investors): | Shareholder | Shares | % | |---|---|---| | Founder A | 5,000,000 | 28.1% | | Founder B | 3,000,000 | 16.9% | | Option pool (refreshed) | 2,666,667 | 15.0% | | Series A investors | 3,333,333 | 18.8% | | Series B investors | 3,777,778 | 21.2% | | Total | 17,777,778 | 100% | Dilution per round: Founder A dilution: - Pre-funding: 50% - Post-Series A: 37.5% (25% dilution) - Post-Series B: 28.1% (25% dilution) - Cumulative dilution: 43.8% Anti-dilution protection: - Investors typically get anti-dilution (weighted average or full ratchet) - Founders and employees do NOT get anti-dilution - Down round impact: Investors get more shares, founders diluted further **409A / market value considerations** Setting exercise price: EMI requirement: - Exercise price must be agreed with HMRC - Typically at current market value (or above) - HMRC valuation: Submit on Form Val 231 Valuation methods: - Discounted cash flow (DCF) - Comparable company analysis - Recent funding round price (with appropriate discount) - Net asset value (for early-stage) Discount for illiquidity: - Private company shares are illiquid - Typical discount: 20-40% from last round price - Example: Series A price £5/share, EMI exercise price £3-4/share **Communicating equity to employees** What employees need to understand: 1. Number of options (not just % — meaningless without context) 2. Current share price / last valuation 3. Total shares outstanding (to calculate %) 4. Vesting schedule 5. Exercise price 6. Tax treatment (EMI vs unapproved) 7. What happens on exit (acquisition / IPO) Example scenario for employee: Grant: 10,000 EMI options at £2 exercise price Company valuation: £20M (10M shares at £2/share) Your ownership: 0.1% (10K / 10M) If company sells for £100M: - Your shares worth: 0.1% × £100M = £100K - Less exercise cost: 10K × £2 = £20K - Gain: £80K - Tax (BADR): £80K × 10% = £8K - Net: £72K If company sells for £500M: - Your shares worth: 0.1% × £500M = £500K - Less exercise cost: £20K - Gain: £480K - Tax: Complex (BADR on first £1M, then 20% CGT) - Approximate net: ~£400K
