Compensation Committee

The Compensation Committee supervises (on a direct basis for our threefour (three as of September 1, 2017) executive officers and a non-direct basis for all other NEOs) our executive compensation program for NEO’s.NEOs. The Compensation Committee has designed a compensation program for NEOs to attract, retain and motivate talent in our competitive market environment while focusing the executive team and the Company on the creation of long-term value for our shareholders. The Compensation Committee has the authority to engage outside consultants or purchase compensation surveys, if needed, for evaluation of executive compensation levels.

Compensation Philosophy

The Compensation Committee supervises (on a direct basis for our three executive officers and a non-direct basis for all other NEOs) our executive compensation program for NEOs. The Compensation Committee has designed a compensation program for NEOs to attract, retain and motivate talent in our competitive market environment while focusing the executive team and the Company on the creation of long-term value for our shareholders. The Compensation Committee has the authority to engage outside consultants or purchase compensation surveys, if needed, for evaluation of executive compensation levels.

NEO positions during the year ended March 31, 20152018 included: Chief Executive Officer and President, Chief Executive Officer/Chairman of the Board, Chief Financial Officer, Chief Sales and Marketing Officer and Senior Vice PresidentsPresident of Commercial Operations. Other positions may be added as business conditions warrant.

We have designed our compensation programs for our NEOs to:

Our Compensation Committee administers four elements for NEOs: base salary (cash), Short-termshort-term incentives (cash), long-term incentives (equity), and benefits. The total compensation package reflects our “Pay for Performance” philosophy, which is to couple employee rewards with the interests of our shareholders. We believe strongly that retention and motivation of successful employees is in the long-term interest of our shareholders. Our compensation program is designed to reward organic and acquisitive revenues and profitability growth of the Company. The Compensation Committee targets the total compensation level to be competitive with comparable companies in terms of size (as measured by revenuerevenues and market capitalization), our industry segments and geographic locations.

Benchmarking

The Compensation Committee, with assistance from our executives if required, researches compensation levels by investigating comparable company records, purchasing third party compensation surveys or engaging compensation consultants. The acquired data is evaluated by the Compensation Committee and is one factor in establishing compensation plans for the NEOs.

To help establish competitive compensation levels, the Compensation Committee examined executive compensation survey data, both baseincluding “base salaries,” “incentive compensation,” and total cash compensation, from Economic Research Institute (“ERI”). The survey data was tailored to include only those U.S. public companies in the “Instrument Manufacturing” segment with revenues between $20 -- $50 - $100 million per year. The ERI survey included 90 public companies in the data set used to establish compensation statistics. This included companies that produced both medical devices and general electronic instruments, along with consumable supplies. The data was further adjusted for the geographic location of each NEO. The data from this analysis was used by the Compensation Committee as one factor in determining compensation levels for base salary and total compensation.

Determination of Target Compensation

For the year ended March 31, 2015,2018, the Compensation Committee determined that an appropriate starting point for total compensation of our NEOs was approximately between the 50^thand 75^th percentile level, compared to the data obtained from the ERI survey. The Compensation Committee used not only the data from the ERI survey, but also considered individual and team executive performance, along with our financial performance, as criteria to establish target compensation levels for each NEO. From that analysis, and in consideration of our past and future expected financial performance, the Compensation Committee made adjustments to base salaries and target total compensation levels for each NEO that were implemented effective June 1, 2014.2017, except for Gary Owens, for whom compensation levels were established when he joined the Company in March 2017 and further modified effective September 1, 2017 upon his transition to President and Chief Executive Officer.

Base Salary

Base salaries for NEOs are determined based upon job responsibilities, level of experience, individual performance and comparisons to the salaries of executives in similar positions from the ERI survey.

Short-term Incentive Plan

Each NEO participates in our Short-term Incentive Plan. The Compensation Committee believes that it is in the best interest of our shareholders to have a substantial component of total compensation “at-risk” and dependent upon our financial performance. For the purpose of the Short-term Incentive Plan, performance is measured by two variables: revenues growth and profitprofitability growth. These variables are considered by the Compensation Committee to be a reliable indicatorsindicator for the creation of long-term shareholder value. Bonus payouts under the Short-term Incentive Plan are tied directly to achievement of these revenues and profitprofitability growth targets for the year. If both the revenues and profitprofitability growth targets are exceeded by a substantial margin, the maximum bonus payments are set at between 50%50 percent and 91%115 percent of the base salary for the various NEOs. Of course, if our financial performance is poor, bonus payments could be at or near $0. The Compensation Committee reserves the right to adjust payments under the Short-term Incentive Plan, in the case of unusual circumstances or events, or economic conditions in general.

We do not disclose the specific target revenues and profitprofitability growth targets set forth in the Short-term Incentive Plan as we believe that the disclosure thereof would cause us competitive harm. Because we are not disclosing these target objectives, we are stating our assessment of how likely it will be for these targets to be achieved by our NEOs. Although achievement of our target objectives involves future performance and, therefore, is subject to uncertainties, the Compensation Committee believes it has established target objectives that are achievable with an appropriate amount of dedication and hard work and, therefore, it is more likely than not that each NEO will earn a bonus under the Short-term Incentive Plan.

Long-term Incentive Plan

The Compensation Committee believes that it is in the best interest of our shareholders to provide long-term incentive to each NEO withthrough their ownership of our stock. Stock ownership by our NEOs directly ties their long-term compensation to the performance of our share price. To achieve this goal, we make stock option grants (and in certain cases grants of restricted stock) to each NEO at the time of hire andhire. We also make stock option grants on an annual basis under our stock compensation plan. These grants are either incentive stock options and/or non-qualified stock options with a term of generally from six to eight years. The grant price is set at 100% of the market price on the day of the grant and the options vest ratably over five to seven years. The awards may or may not have performance conditions associated with the vesting of the stock options. The number of stock options awarded is at the discretion of the Compensation Committee.

Other BenefitsBenefits

Our philosophy is to provide only those other benefits to our named executives that are consistent with those generally offered to all of our other employees. As such, the NEOs have available various health, welfare and retirement (401(k)) benefits.

Employment and Change-in-Control Agreements.We have provided certain of our Executive NEOs with salary continuationemployment agreements. Severance payments will be made 1)The employment agreements provide that in the eventcase of an involuntary separationtermination of servicethe executive without cause or a voluntary separation of service withfor good reason or 2) immediately prior(as defined), salary continuation benefits of one year annual salary (payable over a 12 month period), a prorated payment under the then current cash incentive plan equal to or within 24 months after, a change in controlthe amount the executive would have earned based on the actual performance of the Company for the relevant fiscal year had the executive’s employment not terminated and continuation of Company-provided health benefits for one year. In the case of an involuntary termination without cause or a voluntary termination for good reason. Severancereason that occurs immediately prior to or within two years following a change of control (as defined), the employment agreements provide salary continuation benefits, payments under the then current cash incentive plan equal to the greater of the executive’s annual maximum cash incentive for the fiscal year in which the executive’s termination occurs or the executive’s annual maximum cash incentive payment for the fiscal year immediately preceding the fiscal year in which the executive’s termination occurs and Company-provided health benefits shall continue for two years.

In the case of an involuntary termination of the executive without cause or for good reason, the vesting and other terms of all unvested equity awards will be paid monthly for 12 months or 24 months, respectively, to includeat the individual’s then current monthly salary, and the same percentage of Company-paid health and life insurance benefits. Additionally, all outstanding unvested stock options, and any other equity-based awards that may be granted in the future, will vest immediately with the exercise period extended to the full term of the option (in case 1 above, the acceleration is subject to discretion of the Board of Directors).Directors, while the terms, conditions and restriction of the original grant and respective equity plans for vest equity awards shall remain, provided however, that in the case of stock options, the executive may exercise vested options at any time; (1) within one month after such termination in the case of options granted prior to March 31, 2017; and (2) prior to the natural termination date as stated in the original grant in the case of options granted after March 31, 2017. In the case of an involuntary termination without cause or for good reason immediately prior to or within two years following a change of control, all unvested equity awards will immediately become 100 percent vested, while all other terms, conditions and restrictions of the original grant and the respective equity plan for both vested and unvested equity awards shall remain, including the period during which equity awards may be exercisable.

Nonqualified Deferred Compensation. We do not have any nonqualified defined contribution or deferred compensation plans.

Post-Employment Compensation. We do not have any defined benefit plans, supplemental executive retirement plans or actuarial plans.

EXECUTIVE COMPENSATION

Named Executive Officers

The Securities and Exchange Commission (“SEC”), in Item 402 of Regulation S-K, defines NEOs to include: a) all individuals serving as the registrant’s principal executive officer (“PEO”); b) all individuals serving as the registrant’s principal financial officer (“PFO”); c) the registrant’s three most highly compensated executive officers other than the PEO and PFO; and d) up to two individuals for whom disclosure would have been provided but for the fact the individual was not serving as an executive officer at the end of the last completed fiscal year. Bryan Leo and Garrett Krushefski areGregory T. Dinoia is not an executive officersofficer of the Company, but areis included in the disclosures below as NEOs in accordance with SEC regulations. Steven W. Peterson served as PFO until leaving the Company effective November 30, 2012.

Pay Ratio Disclosure

Under Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(u) of Regulation S-K, we are required to provide the ratio of the annual total compensation of Mr. Owens, who has served as our Chief Executive Officer since September 1, 2017, to the annual total compensation of the median employee of the Company (the “Pay Ratio Disclosure”).

For the year ended March 31, 2018, the median annual total compensation of all employees of the Company and its consolidated subsidiaries (other than the Chief Executive Officer) was $46,286. Based upon the total compensation for the year ended March 31, 2018 reported for Mr. Owens of $1,005,880, our ratio of CEO to median employee pay was 22 to 1. Our median employee is employed in New Jersey in our Instruments business.

The Pay Ratio Disclosure presented above is a reasonable estimate. Because the SEC rules for identifying the median employee and calculating the pay ratio allow companies to use different methodologies, exemptions, estimates and assumptions, the Pay Ratio Disclosure may not be comparable to the pay ratio reported by other companies.

HOW WE IDENTIFIED THE MEDIAN EMPLOYEE. To identify the median Mesa employee, we identified the total employee population that earned wages during the year ended March 31, 2018 and, in accordance with SEC rules, excluded the CEO to arrive at the median employee consideration pool. We then calculated each employee’s total compensation earned for the year in accordance with SEC rules to use as the basis for the pay ratio. We used this total calculated compensation data to then identify the mathematically median employee from the consideration pool. Foreign exchange rates were translated to the U.S. dollar equivalent based on the average rates for the year ended March 31, 2018. We compared the median employee’s compensation to Mr. Owens as he was our CEO as of the reporting date.
