Defined Benefit Plans | 12 Months Ended

Dec. 31, 2017
Defined Benefit Plans | 14. Defined Benefit Plans We have a number of pension plans in the United States, covering many of the Company’s employees, however these plans have been closed to new hires. The plans provide for payment of retirement benefits, mainly commencing between the ages of 55 and 65. After meeting certain qualifications, an employee acquires a vested right to future benefits. The benefits payable under the plans are generally determined on the basis of an employee’s length of service and/or earnings. Employer contributions to the plans are made, as necessary, to ensure legal funding requirements are satisfied. Also, from time to time, we may make contributions in excess of the legal funding requirements. Service cost for 2017 relates to benefit accruals in an hourly Union defined benefit plan in our Security segment. Benefit accruals under all other defined benefit pension plans were frozen as of December 31, 2016. In addition, the Company provides postretirement health care and life insurance benefits to certain retirees.

The accumulated benefit obligation exceeds the fair value of assets for all pension plans. Amounts recognized in the consolidated balance sheets consist of:
|  | Pension Benefits |  |  | Postretirement Benefits |
(In millions) |  | 2017 |  |  | 2016 |  |  | 2017 |  |  | 2016 |

In the first quarter of 2013, the Company communicated a plan amendment to reduce health benefits to certain retired employees. Due to the risk of litigation at the time of the initial communication, the Company elected to defer the full recognition of the benefit arising from the plan amendment. Following a favorable court decision in the first quarter of 2016, the Company determined that it would realize the benefit from the plan amendment. As a result, the Company performed a re-measurement of the affected retiree plan liability as of March 31, 2016. This remeasurement resulted in a $10.7 million reduction of accrued retiree benefit plan liabilities and a corresponding increase in prior service credits. In accordance with accounting requirements, the liability reduction from this remeasurement is recorded as amortization of prior service credits in net income. In addition, we recorded a $0.9 million actuarial loss during the first quarter of 2016. In the third quarter of 2015, we recognized actuarial losses of $6.1 million in discontinued operations related to curtailment accounting due to the sale of the Waterloo tool storage business in addition to the $2.5 million of actuarial losses reflected below in net periodic benefit cost. As of December 31, 2017, we adopted the new Society of Actuaries MP-2017 mortality tables, resulting in a decrease in our pension benefit obligations of approximately $5.0 million, and a corresponding decrease in deferred actuarial losses in accumulated other comprehensive income. As of December 31, 2016, we adopted the new Society of Actuaries MP-2016 mortality tables, resulting in a decrease in our postretirement obligations of approximately $0.1 million, and a corresponding decrease in deferred actuarial losses in accumulated other comprehensive income. The amounts in accumulated other comprehensive loss on the consolidated balance sheets that have not yet been recognized as components of net periodic benefit cost were as follows:
(In millions) |  | Pension Benefits |  |  | Postretirement Benefits |

Our defined benefit plans Master Trust own a variety of investment assets. All of these investment assets, except for group annuity/insurance contracts are measured using net asset value per share as a practical expedient per ASC 820. Following the retrospective adoption of ASU 2015-07 (Fair Value Measurement (Topic 820): Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share) we excluded all investments measured using net asset value per share in the amount of $633.3 million and $554.9 million as of December 31, 2017 and 2016, respectively, from the tabular fair value hierarchy disclosure. The terms and conditions for redemptions vary for each class of the investment assets valued at net asset value per share as a practical expedient. Real estate assets may be redeemed quarterly with a 45 day redemption notice period. Investment assets in multi-strategy hedge funds may be redeemed semi-annually with a 95 day redemption notice period. Equity, fixed income and cash and cash equivalents have no specified redemption frequency and notice period and may be redeemed daily. As of December 31, 2017 we do not have an intent to sell or otherwise dispose of these investment assets at prices different than the net asset value per share. Our investment strategy is to optimize investment returns through a diversified portfolio of investments, taking into consideration underlying plan liabilities and asset volatility. The defined benefit asset allocation policy of the plans allow for an equity allocation of 0% to 75%, a fixed income allocation of 25% to 100%, a cash allocation of up to 25% and other investments of up to 20%. Asset allocations are based on the underlying liability structure. All retirement asset allocations are reviewed periodically to ensure the allocation meets the needs of the liability structure. Our 2018 expected blended long-term rate of return on plan assets of 6.4% was determined based on the nature of the plans’ investments, our current asset allocation and projected long-term rates of return from pension investment consultants. Estimated Future Retirement Benefit Payments The following retirement benefit payments are expected to be paid:
(In millions) |  | Pension Benefits |  |  | Postretirement Benefits |
2018 |  | $ | 37.4 |  |  | $ | 0.1 |
2019 |  |  | 39.1 |  |  |  | 0.1 |
2020 |  |  | 40.4 |  |  |  | 0.1 |
2021 |  |  | 41.6 |  |  |  | 0.1 |
2022 |  |  | 43.1 |  |  |  | 0.1 |
Years 2023-2027 |  |  | 229.9 |  |  |  | 0.3 |
Estimated future retirement benefit payments above are estimates and could change significantly based on differences between actuarial assumptions and actual events and decisions related to lump sum distribution options that are available to participants in certain plans. Defined Contribution Plan Contributions We sponsor a number of defined contribution plans. Contributions are determined under various formulas. Cash contributions by the Company related to these plans amounted to $29.1 million, $22.7 million and $18.3 million in 2017, 2016 and 2015, respectively.
