Meaning
Supplemental agreements to standard stock option contracts modify the vesting schedule of an executive upon specific triggering events. The use of equity acceleration side letters allows founders and key employees to receive their shares early if the startup is acquired. These documents operate outside the main option plan to offer custom terms to individual hires.
They create distinct obligations that must be tracked alongside the primary equity records.
Contractual Variation
Creating unique terms for individual team members increases the complexity of the capitalization table. If equity acceleration side letters are not recorded centrally, the company faces unexpected payout obligations during an acquisition. This lack of transparency can alienate potential buyers who discover these hidden liabilities.
Governance Challenge
Maintaining consistency across all employment agreements becomes difficult as a company grows. The existence of equity acceleration side letters often leads to disagreements among board members who were not informed of the separate agreements. To manage this risk, every side agreement must receive explicit board approval and be archived in the primary corporate repository.
Without these precautions, the organization risks disputes over the division of transaction proceeds.
Audit Protocol
Reviewing separate agreements ensures that the startup capitalization table remains accurate. This review of equity acceleration side letters protects the company from unexpected share dilution.
