4-year tree · 1-year cliff · refresh keeps the cliff rolling
Equity compensation & stock plans
The standard is 4-year vest with a 1-year cliff. The retention magic is annual refresh grants that extend the cliff each year — keeping a rolling reason to stay. Without education, employees treat equity as a lottery ticket; with it, equity is the load-bearing retention pillar at senior levels.
The vesting curve, at scale
Four vehicles · four tax profiles
ISO
Incentive Stock Option
employees only · §422 IRC
capital-gains rate if held 1 yr post-exercise + 2 yr post-grant
NSO
Non-Qual Stock Option
employees + contractors + advisors
ordinary income at exercise on the spread
RSU
Restricted Stock Unit
modern public-co default
ordinary income at vest · withholding required
ESPP
Employee Stock Purchase Plan
broad-based · post-IPO
15% discount + tax on bargain · §423 qualified version preferred
how senior HR builds rolling retention
Annual refresh grants extend the cliff each year.
Without refresh, year-4 employees have no equity reason to stay — they\'re fully vested. With annual refresh, there\'s always at least 12 months of unvested grant on the books. The exam reliably tests refresh as a retention strategy, not just a comp practice.
Exam Traps
ISO vs NSO tax differs
ISO has favorable tax if held; NSO is ordinary income at exercise. Senior HR coordinates with finance/tax for grant design.
Vesting cliff prevents day-1 exit
One-year cliff is industry standard. Without it, early hires can vest, leave, retain stake. Senior HR ensures cliff in plan.
RSUs taxed at vest, not grant
Even unsold RSUs trigger tax at vest. Withholding required. Senior HR ensures sell-to-cover or cash for taxes.
ISO must comply with §422 IRC
Strict rules — $100k limit, 10-year term, 90-day post-termination exercise. Violations convert ISO to NSO.
Equity without education fails
Employees who don't understand equity treat it as lottery ticket. Senior HR provides ongoing education on grants, vesting, tax.
Refresh grants drive retention
Annual refresh creates rolling vesting cliff — ongoing reason to stay. Senior HR uses refresh strategically for top performers.
Grant date sets terms. Strike price (options) or share count (RSU).
No vesting until cliff. Departure before cliff means nothing.
Each year (or quarter) more vests. Steady accrual.
Annual refresh extends vesting horizon for retention.
Liquidity event or open window. Tax planning critical.
