Divorces among high-earning spouses involve unique financial challenges. If you or your spouse works in the technology or finance sector, your assets likely include elements of executive pay, such as restricted stock units (RSUs), incentive stock options (ISOs) or other forms of deferred compensation.
These assets are future-oriented, making it difficult to determine whether distributions are marital or separate property. Securing your financial future depends entirely on correctly valuing and dividing these sophisticated financial assets.
When are RSUs considered marital property?
Massachusetts law gives the court power to assign to either spouse all or any part of the other spouse’s estate, regardless of when it was acquired, subject to the court’s consideration of numerous factors to achieve an equitable division.
Determining the divisible portion of restricted stock options hinges on the purpose of the original grant. Here are two general assumptions in cases involving these types of assets:
- Compensation for services performed while you were married is a divisible asset.
- Compensation tied to future services you perform after the judgment of divorce is entered is more likely to be considered separate property.
Courts typically determine the divisible portion of unvested stock assets by applying the “Baccanti formula,” which generally uses the date of the divorce judgment as the endpoint for the marital contribution.
Courts critically analyze the vesting schedule and the specific language in the grant agreement to determine which portion of the award constitutes a marital asset. The timing of the grant and the services rendered are the key factors the court considers.
Applying the coverture fraction
To achieve equitable division, Massachusetts courts apply a specific judicial methodology often referred to as the “time rule,” or “coverture fraction.” This formula (which includes the Baccanti formula for dividing stock options) provides a precise, arithmetic division for future-vesting assets.
The fraction’s numerator is the time measured from the grant date to the date of the divorce judgment or final order dividing the assets. The denominator is the total vesting period, from the grant date to the final vest date.
A fractional approach is one of the methods used by Massachusetts courts to divide pensions, particularly when division is made “if and when received.” However, the court’s preferred approach is often the present assignment method, which requires an actuarial valuation and an offsetting division.
Massachusetts courts require a meticulous calculation of the marital property component of these complex assets; you cannot rely on subjective negotiation.
Protecting your financial future requires precision
Dividing these high-value assets is a complex and challenging process, not simply a matter of parties negotiating a “fair” agreement. Your financial future depends on the accurate application of the formula.
The intricate valuation methodologies and the significant financial implications require a skilled legal approach. These sophisticated assets require experienced representation familiar with Massachusetts’ application of the time rule.
