A general member in good standing has the right to participate in an election for one or more members of the board of trustees and of the advisory council.

The organization regularly and consistently monitors and enforces compliance with the conflict of interest policy including in the following ways: 1) the board of trustees conducts an annual review wherein each trustee completes a confidential conflict of interest and disclosure form of interests that could give rise to conflicts and that form is then reviewed by all the other trustees. This is conducted in january of each year at the board's first meeting of the year. 2) at the first meeting of the board in each calendar year, the organization's general counsel provides an annual reminder and training session to the board of trustees regarding the topic of conflict of interest and the board members' duty to disclose and avoid conflicts of interest. 3) the organization maintains a conflict of interest policy in its employee handbook and all staff, including key employees and officers, are required to annually execute an acknowledgement of and agreement to adhere to all policies in the employee handbook. 4) throughout the year, board members as well as key employees and officers are afforded the opportunity to disclose any conflicts that may arise during the year.

Form 990, Part VI, Section B, Line 15

The compensation committee of the arin board of trustees sets the compensation for the ceo. Several factors are considered in setting the compensation rate. The job description for the ceo fully details the expectations for performance. The annual bonus for the ceo is based on job performance, there is no automatic bonus payment given. Arin conducts a full market pricing salary survey every 2-3 years, comparing all company positions to comparable businesses in the area. Ceo salary levels are also pulled from this data. The performance and experience level of the current ceo are also considered when setting the annual bonus and annual pay change. The members of the compensation committee convene periodically throughout the year to assess the performance of the ceo. Annually, they formally meet, analyze the information they have gathered, and decide the annual bonus amount and any salary change. Ceo/president compensation disclosure: based upon total compensation amounts for the president/ceo and all other individuals employed by arin in 2024, the ratio of president/ceo total compensation to the median of employee total compensation is 3.8. Form 990, part vi, section b, line 15b: arin considers the salary survey information, pay raise percentage from our geographic region, and other information gleaned from business publications that pertain to executive pay when determining executive pay. Every 2-3 years, arin conducts a companywide salary survey of all company positions. Updated job descriptions and job titles are provided to a company that works with current detailed data from major compensation surveys. Arin salaries are compared to companies in the local area, the northeast corridor, nationwide technology companies, nationwide trade and membership associations, local trade and membership association, national nonprofit companies and local nonprofit companies.

Form 990, Part VI, Section C, Line 19

The organization's governing documents, financial statements and conflict of interest policy are available and can be found on the organization's website for the same period of disclosure as set forth in section 6104(d).

Supplemental Narrative

Financial Statement Notes

PART X, LINE 2:

Arin is a qualifying not-for-profit organization as defined in section 501(c)(6) of the internal revenue code and is exempt from federal income taxes. Management evaluated arin's tax positions and concluded that arin had taken no uncertain tax positions that require adjustment to the financial statements to comply with the provisions of this guidance. Arin recognizes interest expense and penalties related to income taxes on uncertain tax positions in management and general expenses on the statements of activities and accounts payable and accrued expenses in the statements of financial position. No interest expense and penalties related to income taxes on uncertain tax positions were recognized for the years ended december 31, 2024 and 2023. Arin files income tax returns in the u.s. Federal jurisdiction. In accordance with fasb asc 740, income taxes, arin recognizes tax liabilities for uncertain tax positions when it is more likely than not that a tax position will not be sustained upon examination and settlement with various taxing authorities. Liabilities for uncertain tax positions are measured based upon the largest amount of benefit that is greater than 50% likely of being realized upon settlement. The guidance on accounting for uncertainty in income taxes also addresses derecognition, classification, interest and penalties on income taxes, and accounting in interim periods. With a few exceptions, arin is no longer subject to income tax examinations by the u.s. Federal, state, or local tax authorities for years before fiscal year 2021. Management has evaluated arin's tax positions and has concluded that arin has taken no uncertain tax positions that require adjustment to the financial statements to comply with the provisions of this guidance.
