15. Benefit Plans

Pension and Other Postretirement Benefit Plans

The Company participates in BancWest’s employee retirement plan (“ERP”), a qualified noncontributory defined benefit pension plan that was frozen as of December 31, 1995, for the Company’s employees. As a result of that freeze, there are no further benefit accruals for the Company’s employees. However, employees retain rights to the benefits accrued as of the date of freeze.

No contributions to the pension trust are expected to be made during 2016 for the Company’s participants in the ERP. However, should contributions be required in accordance with the funding rules under the Employee Retirement Income Security Act of 1974 (“ERISA”), including the impact of the Pension Protection Act of 2006, the Company would make those required contributions.

The Company also sponsors an unfunded supplemental executive retirement plan for certain key executives (“SERP”). In addition, the Company sponsors a directors’ retirement plan (“Directors’ Plan”), a non‑qualified pension plan for eligible directors that qualify for retirement benefits based on their years of service as a director. Both the SERP and the Directors’ Plan were frozen as of January 1, 2005 to new participants.

A postretirement benefit plan is also offered to eligible employees that provides life insurance and healthcare benefits upon retirement. The Company provides access to medical coverage for eligible retirees under age 65 at active employee premium rates and a monthly stipend to both retiree and retiree’s spouse after age 65. The Company covers the full cost of life insurance benefits for employees retiring on or before December 31, 2014. The Company discontinued providing this benefit effective January 1, 2015.

The Company expects to contribute $6.8 million to its non‑qualified defined benefit pension plans, the SERP and Directors’ Plan, and $1.1 million to its postretirement medical and life insurance plans in 2016. These contributions reflect the estimated benefit payments for the unfunded plans and may vary depending on retirements during 2016.

Defined Contribution Plans:

401(k) Match Plan

The Company matches employee contributions to the BancWest Corporation 401(k) Savings Plan, a qualified defined contribution plan, up to 5% of the employee’s pay in 2015 and 2014. The plan covers all employees who satisfy eligibility requirements. A select group of key executives who participate in an unqualified grandfathered supplemental executive retirement plan may participate in the 401(k) plan but are not eligible to receive the matching contribution.

The matching employer contributions to the 401(k) plan for the years ended December 31, 2015 and 2014, were $4.1 million and $3.9 million, respectively, and are included in salaries and employee benefits within the combined statements of income.

Incentive Plan for Key Executives

The Company has an Incentive Plan for Key Executives (the “IPKE”), under which awards of cash are paid to key executives. The IPKE limits the aggregate and individual value of the awards that could be issued in any one fiscal year. IPKE expense totaled $12.7 million and $10.3 million for the years ended December 31, 2015 and 2014, respectively, and are included in salaries and employee benefits within the combined statements of income.

Long‑Term Incentive Plan

The Company has a Long‑Term Incentive Plan (the “LTIP”) designed to reward selected key executives for their individual performance and the Company’s performance measured over multi‑year performance cycles.

LTIP expense of $5.6 million and $5.4 million was recognized in the years ended December 31, 2015 and 2014, respectively, and are included in salaries and employee benefits within the combined statements of income.

The following table details the amounts recognized in other comprehensive income during the years presented. Pension benefits include benefits from the qualified and non‑qualified plans. Other benefits include life insurance and healthcare benefits from the postretirement benefit plan.

The Company recognizes the overfunded and underfunded status of its pension plans as an asset and liability in the combined balance sheets.

Unrecognized net gains or losses that exceed 5% of the greater of the PBO or the market value of plan assets as of the beginning of the year are amortized on a straight‑line basis over five years in accordance with ASC 715. Amortization of the unrecognized net gain or loss is included as a component of net periodic pension cost. If amortization results in an amount less than the minimum amortization required under GAAP, the minimum required amount is recorded.

The following table summarizes the change in net actuarial loss and amortization for the years ended December 31, 2015 and 2014:

	Pension Benefits				Other Benefits
(dollars in thousands)	2015		2014		2015		2014

Assumptions

The following weighted‑average assumptions were used to determine benefit obligations at December 31, 2015 and 2014:

	ERP Pension Benefits				SERP Pension Benefits				Other Benefits
	2015		2014		2015		2014		2015		2014
Discount rate	4.40	%	4.15	%	4.40	%	4.15	%	4.40	%	4.15	%
Rate of compensation increase	NA		NA		4.00	%	4.00	%	NA		NA

Weighted‑average assumptions used to determine net periodic benefit cost for the years ended December 31, 2015 and 2014 were as follows:

	ERP Pension Benefits				SERP Pension Benefits				Other Benefits
	2015		2014		2015		2014		2015		2014
Discount rate	4.15	%	4.95	%	4.15	%	4.95	%	4.15	%	4.95	%
Expected long‑term return on plan assets	4.50	%	4.50	%	NA		NA		NA		NA
Rate of compensation increase	NA		NA		4.00	%	4.00	%	NA		NA

To select the discount rate, the Company reviews the yield on high quality corporate bonds. This rate is adjusted to convert the yield to an annual discount rate basis and may be adjusted for the population of plan participants to reflect the expected duration of the benefit payments of the plan.

Assumed healthcare cost trend rates were as follows at December 31, 2015 and 2014:

	2015		2014
Healthcare cost trend rate assumed for next year	7.00	%	7.00	%
Rate to which the cost trend is assumed to decline (the ultimate trend rate)	5.00	%	5.00	%
Year that the rate reaches the ultimate trend rate	2023		2023

Assumed healthcare cost trend rates have an impact on the amounts reported for the healthcare plans. A one percentage‑point change in the assumed healthcare cost trend rates would have had the following pre‑tax effect:

	One Percentage‑		One Percentage‑
(dollars in thousands)	Point Increase		Point Decrease
Effect on 2015 total of service and interest cost components	$	74	$	(66)
Effect on postretirement benefit obligation at December 31, 2015		432		(399)

Plan Assets

The Company’s portion of ERP assets was allocated as follows at December 31, 2015 and 2014:

	Asset Allocation
	2015		2014
Equity securities	40	%	45	%
Debt securities	55	%	52	%
Other securities	5	%	3	%
Total	100	%	100	%

There was no Banc1West or BNPP stock included in equity securities at December 31, 2015 and 2014.

The assets within the ERP are managed in accordance with ERISA. The objective of the plan is to achieve, over full market cycles, a compounded annual rate of return equal to or greater than the ERP’s expected long‑term rate of return. The ERP’s participants recognize that capital markets can be unpredictable and that any investment could result in periods where the market value of the ERP’s assets will decline in value. Asset allocation is likely to be the primary determinant of the ERP’s return and the associated volatility of returns for the ERP. The Company estimated the long‑term rate of return for 2015 net periodic pension cost to be 4.5%. The return was selected based on a model of U.S. capital market assumptions with expected returns reflecting the anticipated asset allocation of the ERP.

The target asset allocation for the ERP at December 31, 2015, was as follows:

	Target
	Allocation
Equity securities	40	%
Debt securities	55	%
Other securities	5	%
