Pension

The Company maintains a multiemployer defined benefit pension plan (the “Pension Plan”) administered by Pentegra Retirement Services (the “Fund” or “Pentegra Defined Benefit Plan for Financial Institutions”). The Fund does not segregate the assets or liabilities of all participating employers and accordingly, disclosure of plan assets, accumulated vested and nonvested benefits is not possible. Effective July 1, 2006, the Company froze the defined benefit plan by eliminating all future benefit accruals.

In conjunction with the acquisition of Peoples Federal Bancshares, Inc., the parent of Peoples Federal Savings Bank ("Peoples") in 2015, the Company acquired the Peoples Federal Defined Benefit Pension Plan (“Peoples Plan”). The Peoples Plan was frozen at the date of acquisition and will be maintained in the same manner as the Pension Plan. The Peoples Plan is also administered by Pentegra Retirement Services under the same Fund as the Pension Plan.

Additionally, in conjunction with the acquisition of Island Bancorp in 2017, the Company acquired the Edgartown National Bank Employee’s Retirement Plan. This pension plan was frozen at the date of acquisition and was subsequently dissolved.

The Company’s participation in the Pension Plan and the Peoples Plan (the "Pension Plans") for the annual period ended December 31, 2018, is outlined in the table below. The “EIN/Pension Plan Number” column provides the Employer Identification Number (“EIN”) and the three-digit plan number. The funding status of the Pension Plans is determined on the basis of the financial statements provided by the Fund using total plan assets and accumulated benefit obligation. The “FIP/RP Status Pending/Implemented” column indicates plans for which a financial improvement plan (“FIP”) or a rehabilitation plan (“RP”) is either pending or has been implemented. The “Expiration Date of Collective-Bargaining Agreement” column lists the expiration dates of any collective-bargaining agreement(s) to which the Pension Plans are subject.

Contributions to the Fund are based on each individual employer’s experience. The Company bears the market risk relating to the Pension Plan and will continue to fund the Pension Plan as required. The Pension Plan year is July 1^st through June 30^th. The Company’s total contributions to the Pension Plan did not represent more than 5% of the total contributions to the Pension Plan as indicated in the Pension Plan’s most recently available annual report dated June 30, 2018. The comparability of employer contributions is impacted by asset performance, discount rates and the reduction in the number of covered employees year over year.

The Company’s contributions to the Pension Plans were as follows for the periods indicated:



					Required Contributions - Plan Year Allocation
	Cash Payment		Future period funding		2018-2019		2017-2018		2016-2017
	(Dollars in thousands)
2018	$	2,642	$	2,000	$	642	$	—	$	—
2017	$	6,432	$	5,000	$	—	$	1,432	$	—
2016	$	6,245	$	4,000	$	—	$	—	$	2,245

The Company’s total defined benefit plan expense was $1.1 million, $1.9 million, and $2.0 million, for the years ending December 31, 2018, 2017, and 2016, respectively.

Financial information for the Fund is made available through the public Form 5500 which is available by April 15^th of the year following the plan year end.

Postretirement Benefit Plans

Employees retiring from the Bank after attaining age 65, who have rendered at least 10 years of continuous full time service with Rockland Trust are entitled to a fixed contribution toward the premium for postretirement health care benefits and a $5,000 benefit paid upon death. The health care benefits are subject to deductibles, co-payment provisions and other limitations. The Bank may amend or change these benefits periodically. Additionally, the Company has acquired small postretirement plans and/or agreements in conjunction with various acquisitions. The expense related to these plans for the years ending December 31, 2018, 2017, and 2016 was not material.

Supplemental Executive Retirement Plans

The Bank maintains frozen defined benefit supplemental executive retirement plans (“SERP”) for certain highly compensated employees designed to offset the impact of regulatory limits on benefits under qualified pension plans. The Bank also maintains defined benefit SERPs acquired from previous acquisitions. The Bank has established and funded Rabbi Trusts to accumulate funds in order to satisfy the contractual liability of these supplemental retirement plan benefits. These agreements provide for the Bank to pay all benefits from its general assets, and the establishment of these trust funds does not reduce nor otherwise affect the Bank’s continuing liability to pay benefits from such assets except that the Bank’s liability shall be offset by actual benefit payments made from the trusts. The related trust assets included in the Company's available for sale securities portfolio totaled $16.6 million and $16.2 million at December 31, 2018 and 2017, respectively.

The following table shows the defined benefit supplemental retirement expense, and the contributions paid to the plans which were used only to pay the current year benefits as of the dates indicated:

Other Employee Benefits

The Bank may choose to create an incentive compensation plan for senior management and other officers to participate in at varying levels. In addition, the Bank may also pay a discretionary bonus to senior management, officers, and/or non-officers of the Bank. The expense for the incentive plans and the discretionary bonus amounted to $13.8 million, $10.9 million and $10.3 million in 2018, 2017 and 2016, respectively.

The Bank has an Employee Savings Plan that qualifies as a deferred salary arrangement under Section 401(k) of the Internal Revenue Code. Under the Employee Savings Plan, participating employees may defer a portion of their earnings, not to exceed the Internal Revenue Service annual contribution limits. The Bank matches 25% of each employee’s contributions up to the first 6% of the employee’s earnings. The 401(k) Plan incorporates an Employee Stock Ownership Plan for contributions invested in the Company’s common stock. This Plan also provides nondiscretionary contributions in which employees, with one year and 1,000 hours of service, receive a 5% cash contribution of eligible pay up to the social security limit and a 10% cash contribution of eligible pay over the social security limit up to the maximum amount permitted by law. Benefits contributed to employees under this defined contribution plan vest immediately. The defined contribution plan expense was $5.4 million, $5.0 million and $4.8 million for the years ended December 2018, 2017 and 2016, respectively.

The Company has a non-qualified deferred compensation plan which allows for deferrals of incentive payments until an elected distribution date in the future. This deferred compensation plan is available to certain highly compensated employees. Deferrals are invested at the election of the participant into one of the actively managed funds made available to the participant through the Company's Investment Management Group. The funds are held in a Rabbi Trust until the elected date of distribution.

The Company has a non-qualified 401(k) Restoration Plan ("Restoration Plan") for certain executive officers. The Restoration Plan is intended to contribute to each participant the amount of matching and discretionary contributions which would have been made to the existing Rockland Trust 401(k) plan on the participant's behalf, but were prohibited due to Internal Revenue Code limitations. Deferrals are invested at the election of the participant into one of the actively managed funds made available to the participant through the Company's Investment Management Group or in the Company's stock. These funds are held in a Rabbi Trust until the elected date of distribution. The Company recognized expense of $278,000, $267,000 and $425,000 related to this plan for services performed for the years ended December 31, 2018, 2017 and 2016, respectively.

As a result of the acquisition of Peoples in 2015, the Company assumed an Employee Stock Ownership Plan and a 401(k) Plan. The Company received approval and terminated both plans during 2016, and as such, there was no expense associated with either plan during 2018, 2017 and 2016.

Also as part of the Peoples acquisition in 2015, the Company assumed various Salary Continuation Agreements with certain current and former senior executives. The agreements require the payment of specified benefits upon retirement over periods of ten or twenty years as described in each agreement. Expense related to the Salary Continuation Agreements was $287,000, $279,000 and $272,000 for the years ended December 31, 2018, 2017 and 2016, respectively.

The Company also assumed a Peoples supplemental retirement plan with a former executive, whereby the amounts paid under this plan commenced upon the executive's retirement and continue for his lifetime. The expense related to the supplemental retirement plan for the years ended December 31, 2018, 2017 and 2016 was not material.

Director Benefits

The Company maintains two deferred compensation plans for the Company’s Board of Directors which permit non-employee directors to defer cash fees, one which was in effect through December 31, 2018 and a new plan which was adopted effective January 1, 2019. Under the plan in effect through December 31, 2018, deferred compensation is invested in Company stock and held by the Company's Investment Management Group. The amount of compensation deferred during 2018, 2017, and 2016 was $142,000, $143,000, and $142,000, respectively.

As a result of the Peoples acquisition during 2015, the Company assumed several Director Retirement Agreements. The agreements require the payment of specified benefits upon retirement over periods of ten or twenty years as described in each agreement. The expense related to the Director Retirement Agreements for the years ended December 31, 2018, 2017 and 2016 was not material.
