### Value Calculation by Type

```
CALCULATING EQUITY VALUE
══════════════════════════════════════════════════════════════

RSUs (SIMPLEST):
─────────────────────────────────────────────────────────────
Value = Number of shares × Current stock price
Example: 200 RSUs × $500 = $100,000 gross value
Net after taxes (~40%): ~$60,000

STOCK OPTIONS:
─────────────────────────────────────────────────────────────
Value = (Current FMV - Strike price) × Number of shares
Example: 50,000 options, $5 strike, $10 FMV
Current value: ($10 - $5) × 50,000 = $250,000
⚠️ But options can be worth $0 if FMV < strike

ESPP:
─────────────────────────────────────────────────────────────
Value = Contribution × (1 / Purchase price - 1 / FMV)
Example: Contribute $10,000, buy at $85, stock at $100
Shares: $10,000 / $85 = 117.6 shares
Value: 117.6 × $100 = $11,765
Gain: $1,765 (17.6% return minimum)

## COMPARING JOB OFFERS

### Public Company RSUs

```
EVALUATING PUBLIC COMPANY RSUs
══════════════════════════════════════════════════════════════

WHAT YOU KNOW:
─────────────────────────────────────────────────────────────
• Current stock price (liquid market)
• Historical volatility
• Number of shares granted
• Vesting schedule

WHAT TO CALCULATE:
─────────────────────────────────────────────────────────────
Gross annual value = (Total RSUs / 4 years) × Current price
Net annual value = Gross × (1 - tax rate)

EXAMPLE:
200 RSUs over 4 years, stock at $500
Annual gross: 50 shares × $500 = $25,000/year
Annual net (~60%): $15,000/year

RISKS TO CONSIDER:
─────────────────────────────────────────────────────────────
• Stock price volatility (look at 52-week range)
• Vesting cliff (leave before 1 year = $0)
• Company performance
• Sector trends

ADJUSTMENTS:
─────────────────────────────────────────────────────────────
Conservative: Use 20% below current price
Moderate: Use current price
Optimistic: Use 20% above current price
```

### Private Company Options

```
EVALUATING STARTUP OPTIONS
══════════════════════════════════════════════════════════════

WHAT YOU KNOW:
─────────────────────────────────────────────────────────────
• Number of options granted
• Strike price (from 409A valuation)
• Vesting schedule
• Last funding round valuation

WHAT YOU DON'T KNOW:
─────────────────────────────────────────────────────────────
• Future stock price
• If/when IPO or acquisition
• Dilution from future rounds
• Exercise window if you leave

CRITICAL QUESTIONS TO ASK:
─────────────────────────────────────────────────────────────
1. What is my percentage ownership after exercise?
   (shares / fully diluted shares outstanding)

2. What is the current 409A valuation and last preferred price?
   (409A should be ~20-40% of preferred price)

3. What is the liquidation preference stack?
   (preferred shareholders get paid first)

4. How much runway does the company have?
   (more runway = more likely to reach exit)

5. What happens to my options if I leave?
   (90 days to exercise is standard, but costly)

EXPECTED VALUE CALCULATION:
─────────────────────────────────────────────────────────────
EV = P(success) × (Exit price - Strike) × Shares × (1 - dilution)

Example:
50,000 options, $5 strike
30% chance of IPO at $50/share
Expected 20% dilution before exit

EV = 0.30 × ($50 - $5) × 50,000 × 0.80 = $540,000

⚠️ But 70% chance of $0 (no IPO or stock < $5)
```

### ESPP Analysis

```
ESPP VALUE ANALYSIS
══════════════════════════════════════════════════════════════

TYPICAL ESPP TERMS:
─────────────────────────────────────────────────────────────
• 15% discount on stock purchase
• 6-month purchase periods
• Lookback provision (use lower of start/end price)
• Max contribution: $25,000 FMV per year

ESPP RETURN CALCULATION:
─────────────────────────────────────────────────────────────
Without lookback (stock flat):
Buy at $85 (15% discount), worth $100 = 17.6% return

With lookback (stock rises 20%):
Offering start: $100, Offering end: $120
Buy at $85 (15% off $100), worth $120 = 41% return

With lookback (stock falls 10%):
Offering start: $100, Offering end: $90
Buy at $76.50 (15% off $90), worth $90 = 17.6% return

CONCLUSION:
─────────────────────────────────────────────────────────────
ESPP is nearly "free money" - minimum ~15% return
Always max out ESPP contribution if you can afford it
Sell immediately for guaranteed return (no stock risk)

Bonus: 15% target = $27,000

Annual compensation:
Salary: $180,000
RSU value/year: $25,000 gross / ~$15,000 net
ESPP value/year: ~$1,765 gross
Bonus (expected): $27,000

OFFER B: PRIVATE STARTUP

Base salary: $200,000
Options: 50,000 × ($10 FMV - $5 strike) = $250,000 current value
No ESPP, No bonus

Annual compensation:
Salary: $200,000
Options value/year: $62,500 gross (if stock stays at $10)

TOTAL: ~$262,500/year gross IF successful
CERTAINTY: Low (private stock, illiquid, risky)

EXPECTED VALUE ANALYSIS:
─────────────────────────────────────────────────────────────
If startup has 30% success probability:
EV of options: 0.30 × $250,000 = $75,000 over 4 years
EV annual: $18,750

Risk-adjusted annual: $200,000 + $18,750 = $218,750

PUBLIC COMPANY WINS on risk-adjusted basis ($234K > $219K)
STARTUP WINS if you believe probability is higher

## NEGOTIATION GUIDANCE

```
NEGOTIATING EQUITY
══════════════════════════════════════════════════════════════

WHAT'S NEGOTIABLE:
─────────────────────────────────────────────────────────────
✓ Number of shares/options
✓ Vesting schedule (accelerated vesting on change of control)
✓ Exercise window post-departure (ask for 5-10 years)
✓ Cliff period (ask for 6-month cliff instead of 12)
✓ Refresh grants (annual equity refreshers)
✓ Sign-on bonus to offset equity gap from leaving current job

WHAT TO ASK FOR (STARTUP):
─────────────────────────────────────────────────────────────
1. Extended exercise window (90 days is hostile, ask for 5+ years)
2. Early exercise rights with 83(b) election
3. Single-trigger acceleration on acquisition
4. Clearer equity percentage (not just share count)

WHAT TO ASK FOR (PUBLIC):
─────────────────────────────────────────────────────────────
1. More RSUs (easier to get than salary increase)
2. Sign-on bonus for equity you're leaving behind
3. Annual refresh grants
4. More favorable vesting (e.g., monthly vs. quarterly)
```

## STRATEGIC PLANNING

```
EQUITY STRATEGY TIMELINE
══════════════════════════════════════════════════════════════

STARTUP (PRE-IPO):
─────────────────────────────────────────────────────────────
Early stage: Consider early exercise with 83(b)
Mid stage: Evaluate AMT exposure on exercise
Pre-IPO: Plan liquidity strategy, secondary sales?
Post-IPO: Diversify after lockup expires

PUBLIC COMPANY:
─────────────────────────────────────────────────────────────
At vesting: Decide sell vs hold (default: sell to diversify)
Quarterly: Review concentration, rebalance if needed
Tax season: Tax-loss harvest if positions are down
Annually: Evaluate ESPP participation

JOB TRANSITION:
─────────────────────────────────────────────────────────────
Before leaving: Know your exercise deadlines
Unvested: Forfeit (negotiate acceleration if possible)
Vested options: Decide to exercise or let expire
Vested RSUs: Already yours, continue holding/selling
```

## BEST PRACTICES

### Do's ✅
1. **Understand all equity types** - They have very different values/risks
2. **Calculate after-tax value** - Gross value is misleading
3. **Ask the right questions** - Especially for private companies
4. **Diversify systematically** - Don't let concentration build
5. **Plan for exercise costs** - Options require cash
6. **Max out ESPP** - Nearly free money

### Don'ts ❌
1. **Don't accept share count without context** - Ask for percentage
2. **Don't ignore dilution** - Future funding reduces your stake
3. **Don't forget AMT** - ISO exercise can trigger huge tax bill
4. **Don't wait until deadline** - Plan options strategy early
5. **Don't assume startup options are valuable** - Many go to $0
6. **Don't compare gross values** - Tax treatment varies dramatically
