PENSION AND OTHER POST-RETIREMENT PLANS |
PENSION AND OTHER POST-RETIREMENT PLANS | 11.PENSION AND POST-RETIREMENT PLANS Non-bargaining Plans: The Company has two funded qualified single-employer defined benefit pension plans that cover certain non‑bargaining unit employees and bargaining unit employees. In addition, the Company has plans that provide certain retiree health care and life insurance benefits to substantially all salaried, non-bargaining employees hired before 2008 and to certain bargaining unit employees. Employees are generally eligible for such benefits upon retirement and completion of a specified number of years of service. The Company does not pre-fund these health care and life insurance benefits, and has the right to modify or terminate certain of these plans in the future. Most non-bargaining retirees pay a portion of the benefit costs. Plan Administration, Investments and Asset Allocations: The Company has an Investment Committee that meets regularly with investment advisors to establish investment policies, direct investments and select investment options for the qualified plans. The Investment Committee is also responsible for appointing investment managers and monitoring their performance. The Company’s investment policy permits investments in marketable equity securities, such as domestic and foreign stocks, domestic and foreign bonds, venture capital, real estate investments, and cash equivalents. The Company’s investment policy does not permit direct investment in certain types of assets, such as options or commodities, or the use of certain strategies, such as short selling or the purchase of securities on margin. The Company’s investment strategy for its qualified pension plan assets is to achieve a diversified mix of investments that provides for long-term growth at an acceptable level of risk, and to provide sufficient liquidity to fund ongoing benefit payments. The Company has engaged a number of investment managers to implement various investment strategies to achieve the desired asset class mix, liquidity and risk diversification objectives. The Company’s target and actual asset allocations at December 31, 2016 and 2015 were as follows:
Asset Categories |  | Target |  | 2016 |  | 2015 |
Domestic equity securities |  | 53 | % | 62 | % | 62 | %
International equity securities |  | 15 | % | 13 | % | 13 | %
Debt securities |  | 22 | % | 17 | % | 18 | %
Real estate |  | 5 | % | 6 | % | 6 | %
Other and cash |  | 5 | % | 2 | % | 1 | %
Total |  | 100 | % | 100 | % | 100 | %
The Company’s investments in equity securities primarily include domestic large-cap and mid-cap companies, but also includes an allocation to small-cap and international equity securities. Equity investments do not include any direct holdings of the Company’s stock but may include such holdings to the extent that the stock is included as part of certain mutual fund holdings. Debt securities include investment-grade and high-yield corporate bonds from diversified industries, mortgage-backed securities, and U.S. Treasuries. Other types of investments include funds that invest in commercial real estate assets, and to a lesser extent, private equity investments in technology companies. All assets within specific funds are allocated to the target asset allocation of the fund. The expected return on plan assets is principally based on the Company’s historical returns combined with the Company’s long-term future expectations regarding asset class returns, the mix of plan assets, and inflation assumptions. Actual return on plan assets for the periods presented are as follows:
Actual Return on Plan Assets |  | Returns |
One-year return |  | 8.3 | %
Three-year return |  | 4.0 | %
Five-year return |  | 9.4 | %
Long-term average return (since plan inception in 1989) |  | 8.3 | %
The Company’s pension plan assets are held in a master trust and are stated at estimated fair values of the underlying investments. Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date. Equity Securities: Domestic and international common stocks are valued by obtaining quoted prices on recognized and highly liquid exchanges. Fixed Income Securities: Corporate bonds and U.S. government treasury and agency securities are valued based upon the closing price reported in the market in which the security is traded. U.S. government agency and corporate asset-backed securities may utilize models, such as a matrix pricing model, that incorporate other observable inputs when broker/dealer quotes are not available, such as cash flow, security structure, or market information. Real Estate, Private Equity and Insurance Contract Interests: The fair value of real estate, private equity and insurance contract interests are determined by the issuer based on the unit values of the funds. Unit values are determined by dividing the fund’s net assets by the number of units outstanding at the valuation date. Fair value for underlying investments in real estate is determined through independent property appraisals. Fair value of underlying investments in private equity is determined based on information provided by the general partner taking into consideration the purchase price of the underlying securities, developments concerning the investee company subsequent to the acquisition of the investment, financial data and projections of the investee company provided by the general partner, and such other factors as the general partner deems relevant. Insurance contracts are principally invested in real estate assets, which are valued based upon independent appraisals. The fair values of the Company’s pension plan assets at December 31, 2016 and 2015, by asset category, are as follows (in millions):

Contributions to each of the qualified single-employer defined benefit pension plans are determined annually by the Company’s pension administrative committee, based upon the actuarially determined minimum required contribution under the Employee Retirement Income Security Act of 1974 (“ERISA”), as amended, the Pension Protection Act of 2006, and the maximum deductible contribution allowed for tax purposes. In 2016, 2015 and 2014, the Company contributed $7.5 million, $4.7 million and $6.5 million, respectively, in pension contributions in these plans. The Company’s funding policy is to contribute cash to its pension plans so that it meets at least the minimum contribution requirements. The benefit formulas for employees who are members of collective bargaining units are determined according to the collective bargaining agreements, either using final average pay as the base or a flat dollar amount per year of service. Effective December 31, 2011, the Company froze benefit accruals under the final average pay formula for salaried, non-bargaining unit employees hired before January 1, 2008 and transitioned them to the same cash balance formula for employees hired on or after January 1, 2008. Retirement benefits under the cash balance formula are based on a fixed percentage of employee eligible compensation, plus interest. The plan interest credit rate will vary from year to year based on the ten-year U.S. Treasury rate. Benefit Plan Assets and Obligations: The measurement date for the Company’s benefit plan disclosures is December 31 of each year.

The estimated net loss and prior service credit for the qualified pension plans that will be amortized from accumulated other comprehensive loss into net periodic benefit cost, net of tax, in 2017 is $1.7 million. The estimated net loss and prior service cost for the other post-retirement benefit plans that will be amortized from accumulated other comprehensive loss into net periodic benefit cost, net of tax, in 2017 is $0.9 million. Unrecognized gains and losses of the post-retirement benefit plans are amortized over five years. Although current health care costs are expected to increase, the Company attempts to mitigate these increases by maintaining caps on certain of its benefit plans, using lower cost health care plan options where possible, requiring that certain groups of employees pay a portion of their benefit costs, self‑insuring for certain insurance plans, encouraging wellness programs for employees, and implementing measures to mitigate future benefit cost increases. Components of the net periodic benefit cost and other amounts recognized in other comprehensive income (loss) for the qualified pension plans and the other post-retirement benefit plans during 2016, 2015, and 2014 are shown below (in millions):

In 2014, the Company adopted a modified version of the new mortality table (RP-2014) issued by the Society of Actuaries in October 2014 along with a modified mortality improvement scale for the purposes of determining the Company’s mortality assumption used in its defined benefit and other post-retirement plan liability calculations. The use of the new table resulted in an increase of approximately $17.6 million and $3.9 million to the projected benefit obligation for pension and other post-retirement benefits, respectively as of December 31, 2014. If the assumed health care cost trend rate were increased or decreased one percentage point, the accumulated post-retirement benefit obligation, as of December 31, 2016, 2015, and 2014 and the net periodic post-retirement benefit cost for 2016, 2015 and 2014, would have increased or decreased as follows (in millions):

Non-qualified Pension Plans: The Company has non-qualified supplemental pension plans covering certain employees and retirees, which provide for incremental pension payments from the Company’s general funds so that total pension benefits would be substantially equal to amounts that would have been payable from the Company’s qualified pension plans if it were not for limitations imposed by income tax law. A few employees and retirees receive additional supplemental pension benefits. Non-qualified pension plan obligations recognized in the Consolidated Balance Sheets and expenses recognized in accumulated other comprehensive loss at December 31, 2016 and 2015 are as follows (in millions):

A discount rate of 3.4 percent was used in determining both the 2016 and 2015 non-qualified pension plan obligations. The estimated net loss and prior service credit for the non-qualified pension plans that will be amortized from accumulated other comprehensive loss into net periodic benefit cost, net of tax, in 2017 is $0.1 million.

Defined Contribution Plans: The Company sponsors defined contribution plans that qualify under Sections 401(a) and 401(k) of the Internal Revenue Code. The Company may make discretionary matching contributions equal to a specified percentage of each participant’s 401(k) contributions. For the plan year ended December 31, 2016, the Company provided matching contributions of up to 6 percent of eligible employee compensation. The Company’s matching contributions expensed under these plans totaled $2.1 million, $2.0 million and $1.6 million for years ended December 31, 2016, 2015 and 2014. The Company may also provide a discretionary profit sharing contribution under the qualified defined contribution plans, to salaried, non-bargaining unit employees, if both a minimum threshold of Company performance is achieved and the Board has approved the profit sharing contribution. For certain eligible employees, supplemental profit sharing contributions are credited under a non-qualified plan to be paid after separation from service from the Company’s general funds so that total profit sharing contributions would be substantially equal to amounts that would have been contributed to the Company’s qualified defined contribution plans if it were not for limitations imposed by income tax law. There were no discretionary profit sharing contributions made in 2016. Profit sharing contributions expensed in 2015 and 2014 were $1.9 million and $1.6 million, respectively. Multi-employer Bargaining Plans: The Company contributes to multi-employer defined benefit pension plans under the terms of collective-bargaining agreements that cover its bargaining unit employees. Contributions are generally based on amounts paid for union labor or cargo volume. The risks of participating in multi-employer plans are different from single-employer plans because assets contributed to the multi-employer plan by one employer may be used to provide benefits to employees of other participating employers. Additionally, if one employer stops contributing to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers. The multi-employer pension plans are subject to the plan termination insurance provisions of ERISA and are paying premiums to the Pension Benefit Guaranty Corporation (“PBGC”). The statutes provide that an employer who withdraws from, or significantly reduces its contribution obligation to, a multi-employer plan generally will be required to continue funding its proportional share of the plan’s unfunded vested benefits. As of December 31, 2016, the Company’s estimated benefit plan withdrawal obligations were $220.8 million. Except as described in Note 12, no withdrawal obligations have been recorded by the Company in the consolidated balance sheets at December 31, 2016 and 2015 as the Company has no present intention of withdrawing from and does not anticipate termination of any of these plans. Information regarding the Company’s participation in multi-employer pension plans is outlined in the table below. The “EIN/Pension Plan Number” column provides the Employer Identification Number (“EIN”) and the three-digit plan number, if applicable. Unless otherwise noted, the most recent Pension Protection Act zone status available in 2016 and 2015 is for the plan’s year-end at December 31, 2016 and 2015, respectively. The zone status is based on information that the Company received from the plan and is certified by the plan’s actuary. Among other factors, plans in the red zone are generally less than 65 percent funded, plans in the yellow zone are less than 80 percent funded, and plans in the green zone are at least 80 percent funded. The funding improvement plan (“FIP”) or rehabilitation plan (“RP”) column indicates the status which is either pending or has been implemented. The last column lists the expiration dates of the collective-bargaining agreements to which the plans are subject.

| (1) |  | The Plan is not subject to the PPA funding requirements under IRS Section 432 as the Plan was not in effect on July 16, 2006.
| (2) |  | In 2012, the Company agreed to contribute at least 11.7 percent of total wages paid to employees in covered Marine Engineer Benefits Association (“MEBA”) employment to the MEBA Pension Trust by a reallocation of the total labor cost under the collective bargaining agreement. The pension contribution rate was determined by the plan’s actuary to be necessary to maintain full funding of the pension plan and is fully offset by a reallocation of wages and other benefits.
