Note 8: Employee Benefit Plans

401(k) Plan

The Company has a Retirement Accumulation Plan qualifying under IRS Code Section 401(k), in which NBI, NBB and NBFS are participating employers. Eligible participants may contribute up to 100% of their total annual compensation to the plan, subject to certain limits based on federal tax laws. Employee contributions are matched by the employer based on a percentage of an employee’s total annual compensation contributed to the plan. For the years ended December 31, 2015, 2014 and 2013, the Company contributed $294, $273 and $282, respectively, to the plan.

Employee Stock Ownership Plan

The Company has a nonleveraged Employee Stock Ownership Plan (ESOP) which enables employees of NBI and its subsidiaries who have one year of service and who have attained the age of 21 prior to the plan’s January 1 and July 1 enrollment dates to own NBI common stock. Contributions to the ESOP, which are not mandatory, are determined annually by the Board of Directors. Contribution expense amounted to $200, $100 and $275 in the years ended December 31, 2015, 2014 and 2013, respectively. Dividends on ESOP shares are charged to retained earnings. As of December 31, 2015, the number of shares held by the ESOP was 240,874. All shares held by the ESOP are treated as outstanding in computing the Company’s basic net income per share. Upon reaching age 55 with ten years of plan participation, a vested participant has the right to diversify 50% of his or her allocated ESOP shares and NBI or the ESOP, with the agreement of the Trustee, is obligated to purchase those shares. The ESOP contains a put option which allows a withdrawing participant to require the Company or the ESOP, if the plan administrator agrees, to purchase his or her allocated shares if the shares are not readily tradable on an established market at the time of distribution.

Salary Continuation Plan

The Company has a Salary Continuation Plan for certain key officers. The plan provides the participating officers with supplemental retirement income, payable for the greater of 15 years after retirement or the officer’s lifetime. The expense accrued for the plans in 2015, 2014, and 2013, based on the present value of the retirement benefits, amounted to $396, $246, and $194, respectively. The plan is unfunded. However bank-owned life insurance has been acquired on the life of the key employees in amounts sufficient to discharge the obligations of the agreement.

Defined Benefit Plan

The Company’s defined benefit pension plan covers substantially all employees. The plan benefit formula is based upon the length of service of retired employees and a percentage of qualified W-2 compensation during their final years of employment. Information pertaining to activity in the plan is as follows:

Long Term Rate of Return

The Company, as plan sponsor, selects the expected long-term rate-of-return-on-assets assumption in consultation with its investment advisors and actuary. This rate is intended to reflect the average rate of earnings expected to be earned on the funds invested or to be invested to provide plan benefits. Historical performance is reviewed, especially with respect to real rates of return (net of inflation), for the major asset classes held or anticipated to be held by the trust, and for the trust itself. Undue weight is not given to recent experience, which may not continue over the measurement period, but higher significance is placed on current forecasts of future long-term economic conditions.

Because assets are held in a qualified trust, anticipated returns are not reduced for taxes. Further, and solely for this purpose, the plan is assumed to continue in force and not terminate during the period during which assets are invested. However, consideration is given to the potential impact of current and future investment policy, cash flow into and out of the trust, and expenses (both investment and non-investment) typically paid from plan assets (to the extent such expenses are not explicitly estimated within periodic cost).

The Company, as plan sponsor, has adopted a Pension Administrative Committee Policy (the Policy) for monitoring the investment management of its qualified plans. The Policy includes a statement of general investment principles and a listing of specific investment guidelines, to which the committee may make documented exceptions. The guidelines state that, unless otherwise indicated, all investments that are permitted under the Prudent Investor Rule shall be permissible investments for the defined benefit pension plan. All plan assets are to be invested in marketable securities. Certain investments are prohibited, including commodities and future contracts, private placements, repurchase agreements, options and derivatives. The Policy establishes quality standards for fixed income investments and mutual funds included in the pension plan trust. The Policy also outlines diversification standards.

The preferred target allocation for the assets of the defined benefit pension plan is 65% in equity securities and 35% in fixed income securities. Equity securities include investments in large-cap and mid-cap companies primarily located in the United States, although a small number of international large-cap companies are included. There are also investments in mutual funds holding the equities of large-cap and mid-cap U.S. companies. Fixed income securities include U.S. government agency securities and corporate bonds from companies representing diversified industries. There are no investments in hedge funds, private equity funds or real estate.
