Pension and Other Post-Retirement Benefit Plans | PENSION AND OTHER POST-RETIREMENT BENEFIT PLANS We sponsor a number of defined benefit pension plans. The primary plans are The Hershey Company Retirement Plan and The Hershey Company Retirement Plan for Hourly Employees. These are cash balance plans that provide pension benefits for most domestic employees hired prior to January 1, 2007. We also sponsor two post-retirement benefit plans: health care and life insurance. The health care plan is contributory, with participants’ contributions adjusted annually. The life insurance plan is non-contributory. Obligations and Funded Status A summary of the changes in benefit obligations, plan assets and funded status of these plans is as follows: Pension Benefits Other Benefits December 31, 2017 2016 2017 2016 Change in benefit obligation Projected benefit obligation at beginning of year $ 1,118,318 $ 1,169,424 $ 242,846 $ 255,617 Service cost 20,657 23,075 263 299 Interest cost 40,996 41,875 8,837 9,731 Plan amendments (8,473 ) (43,065 ) — — Actuarial (gain) loss 40,768 15,804 2,207 (2,998 ) Settlement (44,978 ) (59,784 ) — — Currency translation and other 6,749 1,416 889 314 Benefits paid (56,473 ) (30,427 ) (18,930 ) (20,117 ) Projected benefit obligation at end of year 1,117,564 1,118,318 236,112 242,846 Change in plan assets Fair value of plan assets at beginning of year 1,023,676 1,041,902 — — Actual return on plan assets 121,241 49,012 — — Employer contributions 37,503 21,580 18,930 20,117 Settlement (44,978 ) (59,784 ) — — Currency translation and other 5,257 1,393 — — Benefits paid (56,473 ) (30,427 ) (18,930 ) (20,117 ) Fair value of plan assets at end of year 1,086,226 1,023,676 — — Funded status at end of year $ (31,338 ) $ (94,642 ) $ (236,112 ) $ (242,846 ) Amounts recognized in the Consolidated Balance Sheets: Other assets $ 14,988 $ 39 $ — $ — Accrued liabilities (6,916 ) (28,994 ) (20,792 ) (22,576 ) Other long-term liabilities (39,410 ) (65,687 ) (215,320 ) (220,270 ) Total $ (31,338 ) $ (94,642 ) $ (236,112 ) $ (242,846 ) Amounts recognized in Accumulated Other Comprehensive Income (Loss), net of tax: Actuarial net (loss) gain $ (207,659 ) $ (243,228 ) $ 8,313 $ 9,264 Net prior service credit (cost) 30,994 28,360 (1,174 ) (1,565 ) Net amounts recognized in AOCI $ (176,665 ) $ (214,868 ) $ 7,139 $ 7,699 The accumulated benefit obligation for all defined benefit pension plans was $1,077,112 as of December 31, 2017 and $1,081,261 as of December 31, 2016 . Plans with accumulated benefit obligations in excess of plan assets were as follows: December 31, 2017 2016 Projected benefit obligation $ 711,767 $ 1,118,294 Accumulated benefit obligation 675,660 1,081,254 Fair value of plan assets 665,441 1,023,613 Net Periodic Benefit Cost The components of net periodic benefit cost were as follows: Pension Benefits Other Benefits For the years ended December 31, 2017 2016 2015 2017 2016 2015 Amounts recognized in net periodic benefit cost Service cost $ 20,657 $ 23,075 $ 28,300 $ 263 $ 299 $ 542 Interest cost 40,996 41,875 44,179 8,837 9,731 10,187 Expected return on plan assets (57,370 ) (58,820 ) (68,830 ) — — — Amortization of prior service (credit) cost (5,822 ) (1,555 ) (1,178 ) 748 575 611 Amortization of net loss (gain) 33,648 34,940 30,510 (1 ) (13 ) (57 ) Curtailment credit — — (688 ) — — 204 Settlement loss 17,732 22,657 23,067 — — — Total net periodic benefit cost $ 49,841 $ 62,172 $ 55,360 $ 9,847 $ 10,592 $ 11,487 Change in plan assets and benefit obligations recognized in AOCI, pre-tax Actuarial net (gain) loss $ (73,768 ) $ (31,772 ) $ (21,554 ) $ 2,139 $ (3,047 ) $ (26,270 ) Prior service (credit) cost (2,650 ) (41,517 ) 1,748 (744 ) (572 ) (834 ) Total recognized in other comprehensive (income) loss, pre-tax $ (76,418 ) $ (73,289 ) $ (19,806 ) $ 1,395 $ (3,619 ) $ (27,104 ) Net amounts recognized in periodic benefit cost and AOCI $ (26,577 ) $ (11,117 ) $ 35,554 $ 11,242 $ 6,973 $ (15,617 ) Amounts expected to be amortized from AOCI into net periodic benefit cost during 2018 are as follows: Pension Plans Post-Retirement Benefit Plans Amortization of net actuarial loss $ 26,735 $ — Amortization of prior service (credit) cost $ (7,197 ) $ 836 Assumptions The weighted-average assumptions used in computing the benefit obligations were as follows: Pension Benefits Other Benefits December 31, 2017 2016 2017 2016 Discount rate 3.4 % 3.8 % 3.5 % 3.8 % Rate of increase in compensation levels 3.8 % 3.8 % N/A N/A The weighted-average assumptions used in computing net periodic benefit cost were as follows: Pension Benefits Other Benefits For the years ended December 31, 2017 2016 2015 2017 2016 2015 Discount rate 3.8 % 4.0 % 3.7 % 3.8 % 4.0 % 3.7 % Expected long-term return on plan assets 5.8 % 6.1 % 6.3 % N/A N/A N/A Rate of compensation increase 3.8 % 3.8 % 4.1 % N/A N/A N/A The Company’s discount rate assumption is determined by developing a yield curve based on high quality corporate bonds with maturities matching the plans’ expected benefit payment streams. The plans’ expected cash flows are then discounted by the resulting year-by-year spot rates. We base the asset return assumption on current and expected asset allocations, as well as historical and expected returns on the plan asset categories. Prior to December 31, 2017, the service and interest cost components of net periodic benefit cost were determined utilizing a single weighted-average discount rate derived from the yield curve used to measure the plan obligations. Beginning in 2018, we have elected to utilize a full yield curve approach in the estimation of service and interest costs by applying the specific spot rates along the yield curve used in the determination of the benefit obligation to the relevant projected cash flows. We made this change to provide a more precise measurement of service and interest costs by improving the correlation between the projected cash flows to the corresponding spot rates along the yield curve. This change does not affect the measurement of our pension and other post-retirement benefit liabilities but generally results in lower benefit expense in periods when the yield curve is upward sloping. Compared to the method used in 2017, we expect this change to result in lower pension and other post-retirement benefit expense of approximately $5,800 in 2018. We are accounting for this change prospectively as a change in accounting estimate that is inseparable from a change in accounting principle. For purposes of measuring our post-retirement benefit obligation at December 31, 2017 , we assumed a 7.0% annual rate of increase in the per capita cost of covered health care benefits for 2018 , grading down to 5.0% by 2023. For measurement purposes as of December 31, 2016 , we assumed a 7.0% annual rate of increase in the per capita cost of covered health care benefits for 2017 , grading down to 5.0% by 2021. Assumed health care cost trend rates could have a significant effect on the amounts reported for the post-retirement health care plans. A one-percentage point change in assumed health care cost trend rates would have the following effects: Impact of assumed health care cost trend rates One-Percentage One-Percentage Effect on total service and interest cost components $ 148 $ (129 ) Effect on accumulated post-retirement benefit obligation 3,133 (2,758 ) The valuations and assumptions reflect adoption of the Society of Actuaries updated RP-2014 mortality tables with MP-2017 generational projection scales, which we adopted as of December 31, 2017. Adoption of the updated scale did not have a significant impact on our current pension obligations or net period benefit cost since our primary plans are cash balance plans and most participants take lump-sum settlements upon retirement. Plan Assets We broadly diversify our pension plan assets across public equity, fixed income, diversified credit strategies and diversified alternative strategies asset classes. Our target asset allocation for our major domestic pension plans as of December 31, 2017 was as follows: Asset Class Target Asset Allocation Cash 1% Equity securities 25% Fixed income securities 49% Alternative investments, including real estate, listed infrastructure and other 25% As of December 31, 2017 , actual allocations were consistent with the targets and within our allowable ranges. We expect the level of volatility in pension plan asset returns to be in line with the overall volatility of the markets within each asset class. The following table sets forth by level, within the fair value hierarchy (as defined in Note 6), pension plan assets at their fair values as of December 31, 2017 : Quoted prices in active markets of identical assets Significant other observable inputs Significant other unobservable inputs (Level 3) Investments Using NAV as a Practical Expedient (1) Total Cash and cash equivalents $ 1,179 $ 18,161 $ — $ 730 $ 20,070 Equity securities: Global all-cap (a) — — — 276,825 276,825 Fixed income securities: U.S. government/agency — — — 239,686 239,686 Corporate bonds (b) — 33,019 — 162,633 195,652 Collateralized obligations (c) — 40,350 — 34,538 74,888 International government/corporate bonds (d) — — — 32,447 32,447 Alternative investments: Global diversified assets (e) — — — 149,030 149,030 Global real estate investment trusts (f) — — — 50,213 50,213 Global infrastructure (g) — — — 47,415 47,415 Total pension plan assets $ 1,179 $ 91,530 $ — $ 993,517 $ 1,086,226 The following table sets forth by level, within the fair value hierarchy, pension plan assets at their fair values as of December 31, 2016 : Quoted prices in active markets of identical assets (Level 1) Significant other observable inputs (Level 2) Significant other unobservable inputs (Level 3) Total Cash and cash equivalents $ 576 $ 9,540 $ — $ 10,116 Equity securities: Global all-cap (a) 20,216 242,214 — 262,430 Fixed income securities: U.S. government/agency — 228,648 — 228,648 Corporate bonds (b) — 199,634 — 199,634 Collateralized obligations (c) — 50,532 — 50,532 International government/corporate bonds (d) — 30,928 — 30,928 Alternative investments: Global diversified assets (e) — 146,975 — 146,975 Global real estate investment trusts (f) — 48,000 — 48,000 Global infrastructure (g) — 46,413 — 46,413 Total pension plan assets $ 20,792 $ 1,002,884 $ — $ 1,023,676 (1) Certain investments that are measured at fair value using the net asset value per share (or its equivalent) practical expedient have not been categorized in the fair value hierarchy but are included to reconcile to the amounts presented in our Obligations and Funded Status table. (a) This category comprises equity funds that primarily track the MSCI World Index or MSCI All Country World Index. (b) This category comprises fixed income funds primarily invested in investment grade and high yield bonds. (c) This category comprises fixed income funds primarily invested in high quality mortgage-backed securities and other asset-backed obligations. (d) This category comprises fixed income funds primarily invested in Canadian and other international bonds. (e) This category comprises diversified funds invested across alternative asset classes. (f) This category comprises equity funds primarily invested in publicly traded real estate securities. (g) This category comprises equity funds primarily invested in publicly traded listed infrastructure securities. The fair value of the Level 1 assets was based on quoted prices in active markets for the identical assets. The fair value of the Level 2 assets was determined by management based on an assessment of valuations provided by asset management entities and was calculated by aggregating market prices for all underlying securities. Investment objectives for our domestic plan assets are: l To ensure high correlation between the value of plan assets and liabilities; l To maintain careful control of the risk level within each asset class; and l To focus on a long-term return objective. We believe that there are no significant concentrations of risk within our plan assets as of December 31, 2017 . We comply with the rules and regulations promulgated under the Employee Retirement Income Security Act of 1974 (“ERISA”) and we prohibit investments and investment strategies not allowed by ERISA. We do not permit direct purchases of our Company’s securities or the use of derivatives for the purpose of speculation. We invest the assets of non-domestic plans in compliance with laws and regulations applicable to those plans. Cash Flows and Plan Termination Our policy is to fund domestic pension liabilities in accordance with the limits imposed by the ERISA, federal income tax laws and the funding requirements of the Pension Protection Act of 2006. We fund non-domestic pension liabilities in accordance with laws and regulations applicable to those plans. We made total contributions to the pension plans of $37,503 during 2017 . This included contributions totaling $29,201 to fund payouts from the unfunded supplemental retirement plans and $6,461 to complete the termination of the Hershey Company Puerto Rico Hourly Pension Plan, which was approved in 2016 by the Company's Board Compensation and Executive Organization Committee. In 2016 , we made total contributions of $21,580 to the pension plans. For 2018 , minimum funding requirements for our pension plans are approximately $1,591 . Total benefit payments expected to be paid to plan participants, including pension benefits funded from the plans and other benefits funded from Company assets, are as follows: Expected Benefit Payments 2018 2019 2020 2021 2022 2023-2027 Pension Benefits $ 126,392 $ 78,614 $ 85,804 $ 87,159 $ 107,005 $ 407,769 Other Benefits 20,773 19,026 17,768 16,863 15,767 69,003 During the third quarter of 2017, cumulative lump sum distributions from our supplemental executive retirement plan exceeded the plan’s anticipated annual service and interest costs, triggering the recognition of non-cash pension settlement charges due to the acceleration of a portion of the accumulated unrecognized actuarial loss. In addition, settlement charges were also triggered in the pension plan benefiting our employees in Puerto Rico as a result of lump sum distributions and the purchase of annuity contracts relating to the termination of this plan. Multiemployer Pension Plan During 2016, we exited a facility as part of the 2016 Operational Optimization Program (see Note 7) and no longer participate in the BCTGM Union and Industry Canadian Pension Plan, a trustee-managed multiemployer defined benefit pension plan. Our obligation during the term of the collective bargaining agreement was limited to remitting the required contributions to the plan and contributions made were not significant during 2015 through 2016. Savings Plans The Company sponsors several defined contribution plans to provide retirement benefits to employees. Contributions to The Hershey Company 401(k) Plan and similar plans for non-domestic employees are based on a portion of eligible pay up to a defined maximum. All matching contributions were made in cash. Expense associated with the defined contribution plans was $46,154 in 2017 , $43,545 in 2016 and $44,285 in 2015 . |
