“Each year, prior to submission, the audit committee shall ensure that post's form 990 is reviewed by a member of the committee or a designee of the committee with appropriate qualifications. In addition, the draft submission will be made available to the board prior to filing.”
“When joining the organization, and on an annual basis, board members, members of the investment and audit committees, and all staff fill out a conflict of interest statement. If a change in a person's material interest in a matter that could affect post occurs, that person must amend the conflict of interest statement. All disclosure statements shall be reviewed by the chair of the board governance committee and president.”
“The budget & compensation committee sets the salary of the president and reviews and approve the salaries of the executive team members. The budget & comp committee also reviews and establishes the compensation philosophy, competitive positioning, and salary structure for the rest of the staff and approves all changes to benefits policies. The budget and budget & compensation committee is charged with recommending to the board of directors a compensation package, including base salary, benefits, and retirement contributions, for the president and cfo. When considering the compensation package, the committee reviews compensation of executives of comparable non-profit organizations locally and throughout the united states as well as market data from our compensation consultants and various compensation surveys. The board of directors approves the recommended compensation package on an annual basis before the start of the fiscal year or before the effective date of any change in compensation.”
“The organization makes governing documents and the conflict of interest policy available to the public upon request. The organization's audited financial statements and form 990 are made available via the organization's website each year.”
“Other professional fees: program service expenses 3,135,324. Management and general expenses 93,683. Fundraising expenses 461,189. Total expenses 3,690,196.”
“The organization maintains an audit committee whose duties and responsibilities include recommending to the board of directors the retention and termination of an independent auditor and determining whether to accept the auditor's annual audit of the organization's financial statements. No change to the process occurred for the fye 6/30/2023.”
“Post monitors all of its conservation easements at least annually in order to 1) observe the condition of the property in order to determine whether it is in compliance with easement terms; 2) create a record of easement stewardship and property condition over time; and 3) maintain a working relationship with the landowner. It is post's policy to uphold its conservation easements as written and to identify, investigate, evaluate and respond to any potential violations as quickly as possible. In the case of a material violation, post will require cessation, repair, and/or mitigation of any damage to protected conservation values. Post is prepared to take legal action to defend its rights as easement holder if necessary. Post has a conservation easement stewardship fund to... Provide resources for legal defense and maintains conservation defense insurance through terrafirma rrg llc. Conservation easement documents clearly describe the process for enforcing the terms of the easement should any violation be identified to ensure that corrective actions are taken to cure the violation.”
“The organization periodically receives or purchases conservation easements which limit the allowable uses of the related property to open space uses consistent with the organization's mission. Contributed conservation easements received are recorded as land contributions based on the estimated value given up by the land owner by restricting the use of the property with an easement. Conservation easements purchased bear no future benefit to the organization and are therefore included as part of land and easement transactions expense in the year they are acquired. In connection with the transfer or sale of land, the organization may retain a conservation easement on the land. Because these easements bear no possible future financial benefit to the organization, they are not recorded on the organization's statement of financial position. Sometimes, the organization may transfer a conservation easement to a nonprofit or public agency partner while retaining ownership of the property.”
“Lane stewardship endowment: these funds may be used for expenses to maintain trails, remove invasive and exotic species, undertake erosion prevention and repair, and restore plant and animal habitats. Wilbur's watch endowment: this grant is restricted to activities related to the maintenance of the trail at wilbur's watch on post's cloverdale property. Annual stewardship includes mowing, removal and monitoring of pampas grass, repair or replacement of items such as the bench, telescope and signage, as well as repair of the trail.”
“The organization evaluates its uncertain tax positions and will recognize a loss contingency when it is probable that a liability has been incurred as of the date of the financial statements and the amount of the loss can be reasonably estimated. The amount recognized is subject to estimate and management judgment with respect to the likely outcome of each uncertain tax position. The amount that is ultimately sustained for an individual uncertain tax position for all uncertain tax positions in the aggregate could differ from the amount recognized. As of june 30, 2023 management did not identify any uncertain tax positions.”
