EMPLOYEE BENEFIT PLANS

Retirement Plans

The Company has a

401

(k) retirement plan that covers substantially all employees. The Company has also historically had a discretionary profit sharing and employee stock ownership plan (“ESOP”) covering substantially all employees. Effective

December 31, 2016,

the ESOP was merged into the Company’s

401

(k) retirement plan. This merger allows participants to fully diversify their ESOP account balance and have reporting access to all retirement account balances in

one

place. Contribution expense to the plans totaled

$6,343,000,

$5,488,000

and

$6,278,000

2017,

2016

and

2015,

respectively.

The Company also provides deferred compensation agreements with certain active and retired officers. The agreements provide monthly payments of retirement compensation for either stated periods or for the life of the participant. The charges to income for the plans were

$1,596,000

for

2017,

$1,056,000

for

2016

and

$804,000

for

2015.

Such charges reflect the straight-line accrual over the employment period of the present value of benefits due each participant, as of their full eligibility date, using an appropriate discount factor.

Employee Stock Purchase Plan

The Company established an Employee Stock Purchase Plan in

2015

which generally allows participants to make contributions of up to

$25,000

per year, for the purpose of acquiring the Company’s stock. At the end of each plan year, full shares of the Company’s stock are purchased for each employee based on that employee’s contributions. The Company has issued both general and special stock offerings under the plan. Substantially all employees are eligible for the general stock offering, under which full shares of the Company’s stock are purchased for an amount equal to

95%

of their fair market value at the end of the plan year, or, if lower,

95%

of their fair market value at the beginning of the plan year.

The special stock offering is available to substantially all non-highly compensated employees with at least

six

months of service, and these employees

may

allocate up to

$10,000

to this offering. Under the special stock offering, full shares of the Company’s stock are purchased for an amount equal to

85%

of their fair market value at the end of the plan year, or, if lower,

85%

of their fair market value at the beginning of the plan year.

Stock-Based Compensation Plans

The Company’s Board of Directors has adopted various stock-based compensation plans. The plans provide for the grant of incentive stock options, nonqualified stock options, stock appreciation rights and bonus stock awards. Pursuant to the plans, shares are reserved for future issuance by the Company upon exercise of stock options or awarding of bonus shares granted to directors, officers and other key employees.

Stock-based compensation expense for all stock-based compensation awards granted after

January 1, 2006,

is based on the grant date fair value. For all awards except stock option awards, the grant date fair value is the market value per share as of the grant date. For stock option awards, the fair value is estimated at the date of grant using the Black-Scholes option-pricing model. This model requires the input of highly subjective assumptions, changes to which can materially affect the fair value estimate. Additionally, there

may

be other factors that would otherwise have a significant effect on the value of employee stock options granted but are

not

considered by the model. Accordingly, while management believes that the Black-Scholes option-pricing model provides a reasonable estimate of fair value, the model does

not

necessarily provide the best single measure of fair value for the Company's employee stock options.

The fair value of each option award is estimated on the date of grant using the Black-Scholes option-pricing model that uses various assumptions. Expected volatility is based on historical volatility of the Company’s stock and other factors. The Company uses historical data to estimate option exercise and employee termination within the valuation model. The expected term of options granted is derived from the output of the option valuation model and represents the period of time that options granted are expected to be outstanding. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. Forfeitures are estimated at the time of grant, and are based partially on historical experience.

Share and per share information regarding Stock-Based Compensation Plans has been adjusted to reflect the effects of the Company’s

two

one

stock split which became effective on

February 8, 2018.
