NOTE 7 – PENSION AND OTHER POSTRETIREMENT BENEFITS:

Pension Plans

The Corporation has a qualified defined benefit pension plan covering substantially all of its U.S. employees. Effective July 1, 2015, the plan was amended to freeze benefit accruals and participation in the plan for non-union hourly and salaried participants and, effective January 1, 2016, for employees of the Union Electric Steel Carnegie Steelworkers Location, and replace it with employer contributions of a 3% base contribution and a matching contribution of up to 4% to the defined contribution plan. For 2015, employer contributions to the defined contribution plan totaled $882 and are expected to approximate $1,892 in 2016. The plan changes resulted in a remeasurement of the plan liability, reducing the liability by approximately $10,306, and curtailment losses of $1,303. Additionally, during 2015, the plan was amended to permit lump sum distributions to deferred vested participants and deferred beneficiaries who were not offered a lump sum in 2014.

The defined benefit pension plan is covered by the Employee Retirement Income Security Act of 1974 (“ERISA”); accordingly, the Corporation’s policy is to fund at least the minimum actuarially computed annual contribution required under ERISA. Although no minimum contributions were required for any of the three years, voluntary contributions of $5,000 were made in 2013. Additionally, due to voluntary contributions and relief provided by Moving Ahead for Progress in the 21st Century (“MAP-21”) and, subsequently, the Highway and Transportation Funding Act of 2014 (“HAFTA”), which reduces funding requirements for single-employer defined benefit plans, no minimum contributions are required for 2016; however, voluntary contributions may be made. Estimated benefit payments for subsequent years are $9,434 for 2016, $9,772 for 2017, $10,039 for 2018, $10,274 for 2019, $10,500 for 2020 and $54,600 for 2021 – 2025. The fair value of the plan’s assets as of December 31, 2015 and 2014 approximated $139,376 and $157,048, respectively, in comparison to accumulated benefit obligations of $173,243 and $186,870 for the same periods.

Employees of UES-UK participate in a defined benefit pension plan that was curtailed effective December 31, 2004 and replaced with a defined contribution pension plan. The UES-UK plans are non-U.S. plans and therefore are not covered by ERISA. Instead, the Trustees and UES-UK have agreed to a recovery plan that estimates the amount of employer contributions at £1,123 annually through October 2021, based on U.K. regulations, necessary to eliminate the funding deficit of the plan with such estimates subject to change based on the future investment performance of the plan’s assets. The U.S. dollar equivalent of employer contributions to the defined benefit pension plan approximated $1,715, $1,849 and $1,764 in 2015, 2014 and 2013, respectively, and are expected to approximate $1,662 in 2016. The fair value of the plan’s assets as of December 31, 2015 and 2014 approximated $49,628 (£33,528) and $50,533 (£32,437), respectively, in comparison to accumulated benefit obligations of $63,750 (£43,069) and $70,523 (£45,268) for the same periods. Estimated benefit payments for subsequent years are $1,434 for 2016, $2,116 for 2017, $1,548 for 2018, $2,503 for 2019, $2,837 for 2020 and $13,894 for 2021 – 2025. Contributions to the defined contribution pension plan approximated $382, $407 and $316 in 2015, 2014 and 2013, respectively, and are expected to approximate $315 in 2016.

The Corporation also maintains nonqualified defined benefit pension plans for selected executives in addition to the benefits provided under the Corporation’s qualified defined benefit pension plan. The objectives of the nonqualified plans are to provide supplemental retirement benefits or restore benefits lost due to limitations set by the Internal Revenue Service. The assets of the nonqualified plans are held in a grantor tax trust known as a “Rabbi” trust and are subject to claims of the Corporation’s creditors, but otherwise must be used only for purposes of providing benefits under the plans. No contributions were made to the trust in 2013 – 2015 and none are expected in 2016. The fair market value of the trust at December 31, 2015 and 2014, which is included in other noncurrent assets, was $3,663 and $4,280, respectively. Changes in the fair market value of the trust are recorded as a component of other comprehensive income (loss). The plan is treated as a non-funded pension plan for financial reporting purposes. Accumulated benefit obligations approximated $5,676 and $4,294 at December 31, 2015 and 2014, respectively. Estimated benefit payments for subsequent years, which would represent employer contributions, are approximately $360 for 2016, $387 for 2017, $414 for 2018, $433 for 2019, $461 for 2020 and $2,516 for 2021 – 2025.

Employees at one location participate in a multi-employer plan, I.A.M. National Pension Fund, in lieu of the Corporation’s defined benefit pension plan. A multi-employer plan generally receives contributions from two or more unrelated employers pursuant to one or more collective bargaining agreements. The assets contributed by one employer may be used to fund the benefits provided to employees of other employers in the plan because the plan assets, once contributed, are not restricted to individual employers. The latest report of summary plan information (for the 2014 plan year) provided by I.A.M. National Pension Fund indicates:

 

   

More than 1,750 employer locations contribute to the plan

   

Approximately 275,000 employees participate in the plan

   

Assets of approximately $10.9 billion and a funded status in excess of 100%.

Less than 100 of the Corporation’s employees participate in the plan and contributions are based on a rate per hour. The Corporation’s contributions to the plan equaled $236, $233 and $230 in 2015, 2014 and 2013, respectively, and represent less than five percent of total contributions to the plan by all contributing employers. Contributions are expected to approximate $284 in 2016.

Other Postretirement Benefits

The Corporation provides postretirement health care benefits principally to the bargaining groups of one subsidiary. The plan covers participants and their spouses and/or dependents who retire under the existing pension plan on other than a deferred vested basis and at the time of retirement have also rendered 15 or more years of continuous service irrespective of age. During 2014, effective January 1, 2015, the plan was modified and existing coverage for the bargaining groups was replaced with monthly reimbursements. The plan change resulted in a remeasurement of the plan liability as of May 1, 2014, reducing the liability by approximately $8,914. Additionally, during 2015, the plan was further amended to provide monthly reimbursement for a 5-year period, which further reduced the plan liability by approximately $4,437. Retiree life insurance continues to be provided to substantially all retirees. The Corporation also provides health care and life insurance benefits to former employees of certain discontinued operations. This obligation had been estimated and provided for at the time of disposal. The Corporation’s postretirement health care and life insurance plans are not funded or subject to any minimum regulatory funding requirements. Estimated benefit payments for subsequent years, which would represent employer contributions, are approximately $624 for 2016, $635 for 2017, $659 for 2018, $672 for 2019, $687 for 2020, and $3,058 for 2021 – 2025.

Investment Policies and Strategies

The investment policies and strategies are determined and monitored by the Board of Directors for the U.S. pension plan and by the Trustees (as appointed by UES-UK and the employees of UES-UK) for the foreign pension plan, each of whom employ their own investment managers to manage the plan’s assets in accordance with the policy guidelines. Pension assets are invested with the objective of maximizing long-term returns while minimizing material losses to meet future benefit obligations as they become due. Investments in equity securities are primarily in common stocks of publicly-traded U.S. and international companies across a broad spectrum of industry sectors. Investments in fixed-income securities are principally A-rated or better bonds with maturities of less than ten years, preferred stocks and convertible bonds. The Corporation believes there are no significant concentrations of risk associated with the Plans’ assets.

Attempts to minimize risk include allowing temporary changes to the allocation mix in response to market conditions, diversifying investments among asset categories (e.g., equity securities, fixed-income securities, alternative investments, cash and cash equivalents) and within these asset categories (e.g., economic sector, industry, geographic distribution, size) and consulting with independent financial and legal counsels to assure that the investments and their expected returns and risks are consistent with the goals of the Board of Directors or Trustees.

With respect to the U.S. pension plan, the following investments are prohibited unless otherwise approved by the Board of Directors: stock of the Corporation, futures and options except for hedging purposes, unregistered or restricted stock, warrants, margin trading, short-selling, real estate excluding public or real estate partnerships, and commodities including art, jewelry and gold. The foreign pension plan invests in specific funds. Any investments other than those specifically identified would be considered prohibited.

The following summarizes target asset allocations (within +/-5% considered acceptable) and major asset categories. Certain investments are classified differently for target asset allocation purposes and external reporting purposes.

Fair Value Measurement of Plan Assets

Equity securities and mutual funds are actively traded on exchanges and price quotes for these investments are readily available. Similarly, corporate debt and preferred securities consist of fixed-income securities of U.S. and U.K. corporations and price quotes for these investments are readily available. Common collective trust and commingled funds are not traded publicly, but the underlying assets (such as stocks and bonds) held in these funds are traded on active markets and the prices for the underlying assets are readily observable. For securities not actively traded, the fair value may be based on third-party appraisals, discounted cash flow analysis, benchmark yields and inputs that are currently observable in markets for similar securities.

 

Investment Strategies

The significant investment strategies of the various funds are summarized below.

 

Fund   Investment Strategy   Primary Investment Objective
Temporary Investment Funds   Invests primarily in a diversified portfolio of investment grade money market instruments.   Achieve a market level of current income while maintaining stability of principal and liquidity.
Various Equity Funds   Each fund maintains a diversified holding in common stock of applicable companies (e.g. common stock of small capitalization companies if a small-cap fund, common stock of medium capitalization companies if a mid-cap fund, common stock of foreign corporations if an international fund, etc.).   Outperform the fund’s related index.
Various Growth and Value Funds – Domestic   Invests primarily in common stocks and other equity securities or in common collective funds which invest in common stocks and other equity securities, generally traded on a major U.S. exchange.   Exceed the return of the applicable Russell or S&P Index over a market cycle.
Various Growth and Value Funds – International   Invests primarily in common stocks and other equity securities or in common collective funds which invest in common stocks and other equity securities of issuers organized or conducting business in countries other than the United States.  

For the U.S. Plan – to exceed the return of the corresponding Morgan Stanley Index over a market cycle.

 

For the U.K. Plan – to outperform the applicable FTSE index over a market cycle.

Return Funds   Invests primarily in a diversified portfolio of fixed-income securities of varying maturities or in commingled funds which invest in a diversified portfolio of fixed-income securities of varying maturities.  

For the U.S. Plan – to outperform either the Barclays Capital U.S. Aggregate Index or US Corporate High Yield Index, as applicable, over a prescribed period.

 

For the U.K. Plan – to outperform the applicable FTSE index over a prescribed period.

Alternative Investments – Managed Funds   Invests in equities and equity-like asset classes and strategies, (such as public equities, venture capital, private equity, real estate, natural resources and hedged strategies) and fixed-income securities.   Generate a minimum annual inflation adjusted return of 5% and outperform a traditional 70/30 equities/bond portfolio.
Alternative Investments – Hedge and Absolute Return Funds   Invests in a diversified portfolio of alternative investment styles and strategies.   Generate long-term capital appreciation while maintaining a low correlation with the traditional global financial markets.

Net Periodic Pension and Other Postretirement Benefit Costs

The actual return on the fair value of plan assets is included in determining the funded status of the plans. In determining net periodic pension costs, the expected long-term rate of return on the market-related value of plan assets is used. Differences between the actual return on plan assets and the expected long-term rate of return on plan assets are classified as part of unrecognized actuarial gains or losses and are recorded as a component of accumulated other comprehensive loss on the consolidated balance sheet. When these gains or losses exceed 10% of the greater of the projected benefit obligation or the market-related value of plan assets, they are amortized to net periodic pension and other postretirement costs over the average remaining service period of employees expected to receive benefits under the plans. When the gains or losses are less than 10% of the greater of the projected benefit obligation or the market-related value of plan assets, they are included in net periodic pension and other postretirement costs indirectly as a result of lower/higher interest costs arising from a decrease/increase in the projected benefit obligation.

Net periodic pension and other postretirement benefit costs include the following components for the year ended December 31:

Assumptions

Assumptions are reviewed on an annual basis. The expected long-term rate of return on plan assets is an estimate of average rates of earnings expected to be earned on funds invested or to be invested to provide for the benefits included in the projected benefit obligation. Since these benefits will be paid over many years, the expected long-term rate of return is reflective of current investment returns and investment returns over a longer period. Consideration is also given to target and actual asset allocations, inflation and real risk-free return. The discount rates used in determining future pension obligations and other postretirement benefits for each of the plans are based on rates of return on high-quality fixed-income investments currently available and expected to be available during the period to maturity of the pension and other postretirement benefits. High-quality fixed-income investments are defined as those investments which have received one of the two highest ratings given by a recognized rating agency with maturities of 10+ years.

 

The discount rates and weighted-average wage increases used to determine the benefit obligations as of December 31, 2015 and 2014 are summarized below. The change in discounts rates decreased plan benefit obligations and increased the funded status of the plans by approximately $11,000 as of December 31, 2015 in comparison to December 31, 2014.

 

     U.S. Pension

   Foreign Pension
Benefits
         Other Postretirement

Discount rate

     4.40      4.10        3.65     3.50        4.20     4.00

Wage increases

     3.00      4.00          n/a        n/a             n/a        n/a   

In addition, the assumed health care cost trend rate at December 31, 2015 for other postretirement benefits is 6% for 2016 gradually decreasing to 4.75% in 2019. In selecting rates for current and long-term health care assumptions, the Corporation considers known health care cost increases, the design of the benefit programs, the demographics of its active and retiree populations and expectations of inflation rates in the future. A one percentage point increase or decrease in the assumed health care cost trend rate would result in an inconsequential change to the postretirement benefit obligation at December 31, 2015 and the annual benefit expense for 2015.
