        <ExplanationTxt>NixSar does not have employees and does not pay salaries. Compensation and benefits that are reported are recorded on the books of Butler Healthcare Providers (BMH), a related nonprofit corporation Butler Health System Executive Compensation Philosophy and Process The Board of Trustees recognizes the great challenges and difficulties that healthcare executives face, particularly in the current era of national and state healthcare reform. In addition, the Pittsburgh regional market is highly competitive and changing rapidly. The Board competes for and seeks executive talent on a national basis. It engages expert compensation consultants, utilizing national comparative data to guide the determination of competitive, appropriate levels of compensation. The total compensation program for executives consists of cash compensation and benefits. Factors taken into consideration in determining compensation for executives include: actual performance and effectiveness, market demand and competition for similar positions, experience and tenure in similar positions. Based on these and other pertinent criteria. BHS executive compensation generally will not exceed the 75th percentile of the market. Exceptions to this may be subject to review and recommendation by the Compensation Committee, which in turn is subject to review and approval by the Board of Trustees. Exception must be supported by organizational and /or individual performance, or a retention/recruitment circumstance that warrants such compensation. The Compensation Committee consists exclusively of independent individuals with no real or perceived conflicts of interest in recommending executive compensation guidelines and levels. While benefits are accounted for in Schedule J, actual "take home" pay to the employees typically consists only of base salary, and incentive award earned, if any. Applicable taxes or other withholdings are deducted. Annual increases in base pay, if any, are based on competitive market trends from the comparison group. Supplemental retirement benefits are used as a vehicle for executive recruitment and retention with appropriate vesting periods. The Board of Trustees reviews and approves executive compensation in its entirety, including the use of "tally sheets", which disclose 100% executive compensation. The Board of Trustees engages external compensation and legal expertise to assure reasonableness of executive compensation levels.</ExplanationTxt>
