Employee Benefit Plans [Abstract] |
Employee Benefit Plans | 10. Employee Benefit Plans Defined Benefit Pension Plan The Company has a defined benefit pension plan that covers certain of its executive, professional, administrative and clerical employees, subject to certain specified service requirements. The plan is noncontributory and benefits are based on an employee’s years of service and “final average earnings,” as defined by the plan. The plan provides reduced benefits for early retirement and takes into account offsets for social security benefits. The Company also has an unfunded supplemental retirement plan (“Benefit Equalization Plan”) for certain employees whose benefits under the defined benefit pension plan were reduced because of compensation limitations under federal tax laws. Effective June 1, 2004, all benefit accruals under the Company’s pension plan and Benefit Equalization Plan were frozen; however, the current vested benefit was preserved. Pension disclosure as presented below includes aggregated amounts for both of the Company’s plans, except where otherwise indicated. The Company historically has used the date of its fiscal year-end as its measurement date to determine the funded status of the plan. The long-term investment goals of our plan are to manage the assets in accordance with the legal requirements of all applicable laws; produce investment returns which maximize return within reasonable and prudent levels of risks; and achieve a fully funded status with regard to current pension liabilities. Some risk must be assumed in order to achieve the investment goals. Investments with the ability to withstand short and intermediate term variability are considered and some interim fluctuations in market value and rates of return are tolerated in order to achieve the plan’s longer-term objectives. The plan’s assets are managed by a third-party investment manager. The investment manager is limited to pursuing the investment strategies regarding asset mix and purchases and sales of securities within the parameters defined in the Investment Objectives & Policy Statement and investment management agreement. Investment performance and risk is measured and monitored on an ongoing basis through quarterly investment meetings. A summary of net periodic benefit cost is as follows:

As of December 31, 2015 and 2014, plan assets included approximately $44.1 million and $45.5 million, respectively, of investments in hedge funds which do not have readily determinable fair values. The underlying holdings of the funds are comprised of a combination of assets for which the estimate of fair value is determined using information provided by fund managers. The Company expects to contribute approximately $1.8 million to its defined benefit pension plan in 2016. Future benefit payments under the plans are estimated as follows:

The estimated amount of the net accumulated loss that will be amortized from accumulated other comprehensive loss into net period benefit cost in 2016 is $1.7 million.

The expected long-term rate of return on assets assumption was 6.5% for 2015 and 6.75% for 2014. The expected long-term rate of return on assets assumption was developed considering forward looking capital market assumptions and historical return expectations for each asset class assuming the Company’s target asset allocation and full availability of invested assets. Plan assets are measured at fair value. The following provides a description of the valuation techniques employed for each major asset class: Corporate equities are valued at the closing price reported on the active market on which the individual securities are purchased. Registered investment companies are public investment vehicles valued using the Net Asset Value (NAV) of shares held by the plan at year-end. The NAV is a quoted price in an active market and classified within Level 1 of the valuation hierarchy. Closely held funds held by the plan, which are only available through private offerings, do not have readily determinable fair values. Estimates of fair value of these funds are determined using the information provided by the fund managers and it is generally based on the net asset value per share or its equivalent. Corporate bonds are valued based on market values quoted by dealers who are market makers in these securities, and by independent pricing services which use multiple valuation techniques that incorporate available market information and proprietary valuation models using market characteristics, such as benchmark yield curve, coupon rates, credit spreads, estimated default rates and other features. The following table sets forth the plan assets at fair value in accordance with the fair value hierarchy described in Note 3:

Fund strategies seek to capitalize on inefficiencies identified across different asset classes or markets. Hedge fund strategy types include long-short, event-driven, multi-strategy and distressed credit. Generally, the redemption of the Company’s hedge fund investments is subject to certain notice-period requirements and, as such, the Company has classified these assets as Level 3 assets. The table below sets forth a summary of changes in the fair value of the Level 3 assets:

Section 401(k) Plans The Company has several contributory Section 401(k) plans which cover its executive, professional, administrative and clerical employees, subject to certain specified service requirements. The 401(k) expense provision was $4.0 million in 2015, $3.6 million in 2014 and $3.8 million in 2013. The Company’s contribution is based on a non-discretionary match of employees’ contributions, as defined by each plan. Cash-Based Compensation Plans The Company has multiple cash-based compensation plans and a share-based incentive compensation plan for key employees, which are generally based on the Company’s achievement of a certain level of profit. For information on the Company’s share-based incentive compensation plan, see Note 8. Multiemployer Plans In addition to the Company’s defined benefit pension and contribution plans discussed above, the C ompany participates in multiemployer pension plans for its union construction employees. Contributions are based on the hours worked by employees covered under various collective bargaining agreements. Under the Employee Retirement Income Security Act, a contributor to a multiemployer plan is only liable for its proportionate share of a plan’s unfunded vested liability upon termination, or withdrawal from, a plan. The Company currently has no intention of withdrawing from any of the multiemployer pension plans in which it participates and, therefore, has not recognized a liability for its proportionate share of any unfunded vested liabilities associated with these plans. The following tables summarize key information for the plans that the Company had significant involvement with during the years ended December 31, 2015, 2014 and 201 3.
