ExplanationThe school works directly with town officials and local charitable organizations to assess future needs and the use of current and past monetary grants. The school also makes several other small donations throughout the year based on charitable purposes, historical relationship, and current need. These one-time contributions are not typically monitored by the CFO or Headmaster. Financial aid grants are awarded annually to qualified students and are typically applied as credits to the tuition bill up to the amount of the grant for the current academic year. In some instances, cash payments are issued directly to parents as reimbursements for academic expenses or travel related costs when applicable.ExplanationTxt

Schedule J, Part I, Line 1aTeaching faculty are required to live in on-campus housing as a condition of employment. A taxable housing stipend is paid to a few administrators who live off campus. The Headmaster's home includes some space that is reserved for school-related meetings and student activities. The cost of maintaining this space is paid by the school and recorded as an operating expense. The school will only pay for the cost of a traveling spouse when they are an authorized participant in school related functions. In such cases, the cost is treated as a non-taxable work-related event. The discretionary account is provided to the headmaster as part of the annual budget. The account is used to fund small school related expenses and, as a result, is not reported as a taxable fringe benefit.
Schedule J, Part I, Line 3The salary of Groton's Headmaster is determined annually by the Compensation Committee of the Board. As input to their decisions, the committee reviews the results of the annual APOPS salary survey and the recommendations from an outside consultant. ABOPS is a 40-member organization of independent schools whom we consider to be our peers.
Schedule J, Part I, Line 4The Headmaster's contract, approved by the President of the Board and the Compensation Committee, includes deferred compensation arrangements under Section 457(f). The vesting periods of these plans vary, typically spanning three to five years. The deferred amounts are reported in Schedule J, Part II, Column (C).
Schedule J, Part I, Line 7Most of the listed stipends are either fixed or part of a contracted distribution, but one unplanned stipend was awarded in recognition of service to the school during a CFO transition.
