(1) Mr. Fusco resigned from the Company effective March 8, 2019.

Below we summarize our programs and 2018 pay decisions.

Base Salary

The Compensation Committee believes the purpose of base salary is to provide competitive and fair base compensation that recognizes the executives’ role, responsibilities, experience and performance. Base salary represents fixed compensation that is targeted to be competitive with the practices of comparable banks similar in size and region.

Typically, the Committee sets base salary for each executive in the first quarter of each year effective January 1. Salaries are determined in consideration of the competitive market for similar roles, as well as each individual’s experience, performance and contributions. Input from the Company’s Chief Executive Officer is considered in setting executive salaries, while the Compensation Committee is solely responsible for recommending the Company’s Chief Executive Officer’s salary.

Below is a summary of the salaries approved by the Compensation Committee:

Executive	2017 Base Salary ($)		2018 Base Salary ($)		% Increase
Anthony Labozzetta		441,511		529,813		20.0
Steven M. Fusco(1)		240,747		288,897		20.0
George Lista		185,974		200,729		7.9

(1) Mr. Fusco resigned from the Company effective March 8, 2019.

The salary increases from 2017 to 2018 were a result of the Company’s growth and strong performance and were supported by an executive compensation review conducted by Meridian in 2018.

Executive Incentive Plan

The objective of the Company’s executive incentive plan is to motivate and reward key members of executive management for achieving specific performance goals that support the Company’s strategic plan through the use of cash awards and restricted stock. Awards under this plan represent compensation that must be earned based upon performance. Awards for the CEO and CFO are paid 50% in cash and 50% in equity with subsequent 3 year vesting and the award for the CEO of Tri-State Insurance Agency is paid 100% in cash with the potential for discretionary stock awards.

The performance goals are developed in conjunction with the annual business plan, approved by the Compensation Committee and presented to the full Board for final approval.

The incentive target opportunities and performance measures for the 2018 compensation year are described below.

Award Opportunity: The table below summarizes the 2018 incentive award opportunities (expressed as a percentage of base salary) available under our annual executive incentive plan and paid only upon achievement of the performance goals. The total incentive opportunity is allocated in cash (and equity in the case of the CEO, CLO and CFO) in accordance with the table below. The Committee believes payment in stock provides additional retention and deferral of compensation that reinforces our desire to align pay with shareholder interests and provide long-term compensation.

	Total Incentive Opportunity (% of Salary)									Cash Portion (% of Salary)									Restricted Stock Portion (% of Salary)
	Threshold			Target			Maximum			Threshold			Target			Maximum			Threshold			Target			Maximum
Chief Executive Officer		40.0	%		80.0	%		120.0	%		20.0	%		40.0	%		60.0	%		20.0	%		40.0	%		60.0	%
Chief Financial Officer		30.0	%		60.0	%		90.0	%		15.0	%		30.0	%		45.0	%		15.0	%		30.0	%		45.0	%
Chief Executive Officer, Tri-State Insurance Agency		10.0	%		20.0	%		30.0	%		10.0	%		20.0	%		30.0	%		—			—			—

Performance Measures: The 2018 performance measures required the Company to achieve increased levels of profitability and achieve other key goals aligned with the Company’s business strategy. All participants have at least 50% of their incentive based on Net Income (Corporate or Division) to reinforce our goal to fund incentives based on earnings. Corporate Net Income was adjusted for significant extraordinary events (including acquisition costs and the impact of tax reform – deferred tax asset write down; see footnote below table for details).

Weightings for performance goals can vary by participant. For the CEO and CFO, performance is strictly formulaic, with 50% of the incentive determined by Corporate Net Income and 50% based on 3-Year Average Return on Equity (ROE). We believe a rolling view of ROE as measured for the prior 3 years is an effective way to reward and motivate sustained performance. The CEO, Tri-State Insurance Agency is measured based on the Business Unit goals: Net Income Before Taxes, Total Commissions Revenue and Efficiency Ratio. The Compensation Committee believed these measures would drive the appropriate focus by the executive team on overall performance of the Company.

The performance measures and goals were established by the Compensation Committee and approved unanimously in January 2018. The following tables summarize the measures, weightings and goals at threshold, target and stretch levels. The last column indicates the 2018 performance results for each goal.

Dollars are in thousands.

(1) Reported Net income (GAAP) for Fiscal Year 2018 was $9,923 and ROE was 6.64%, which included significant items that impacted financial results. Those items included the following:

Fiscal Year 2018	Net Income		ROE

Non-GAAP Results	$	11,710		7.81	%

The 3-Year Average ROE was 9.07% (adjusted for significant events in 2018) as compared to the reported result of 8.67%. The Non-GAAP results were utilized for the incentive measurement.

2018 Retention Awards

We made special retention awards to each of our NEOs in 2018 in the form of time-based restricted stock. These one-time awards were intended to recognize and reward the NEOs for their performance and their role in the growth of the Company following the acquisition of Community Bank of Bergen County, NJ in January 2018 and its subsequent integration into the Company. The retention awards are also intended to provide the NEOs with additional incentives to remain employed with us, as such awards will vest in three annual installments, subject to the NEOs' continued employment through the applicable vesting date.

Executive	Retention Award ($)
Anthony Labozzetta		239,610
Steven M. Fusco(1)		131,784
George Lista		95,832

(1) Mr. Fusco resigned from the Company effective March 8, 2019.

Executive Benefits

The Company’s executive compensation program include base salary, annual cash incentive awards, long-term incentive awards and other benefit and perquisites, such as retirement programs.

The Company provides select executives certain benefits and perquisites, which the Compensation Committee believes are reasonable and consistent with the Company’s overall compensation philosophy. The Compensation Committee regularly reviews and refines executive benefits to ensure market competitiveness.

Executive Perquisites. The Company provides a limited number of perquisites to key executives that the Compensation Committee believes are necessary for conducting business are reasonable and enable us to attract and retain high performing employees for our key senior management positions. These benefits also allow our executives to maintain direct contact and involvement with current and prospective customers, as well as non-profit organizations in the communities in which we do business. The Compensation Committee periodically reviews the levels of perquisites and other personal benefits provided to the named executive officers.

The primary perquisites are: corporate owned automobiles for certain executives, club memberships for certain executives and life insurance programs. These perquisites represent a relatively insignificant portion of the total compensation of each named executive officer. The aggregate incremental cost to the Company for these perquisites is set forth in the Summary Compensation Table under the “All Other Compensation” column and related notes.

Risk Management

The Compensation Committee annually reviews our executive compensation program to ensure it does not encourage unnecessary or excessive risk taking. In reviewing the program for risk, the goal of the Compensation Committee is to design an executive compensation program that encourages prudent risk management and discourages inappropriate risk-taking by granting balanced portfolio of executive compensation that includes fixed and variable pay, annual and long-term pay, cash and equity.
