Postemployment Benefits [Abstract] |
PENSIONS AND OTHER POSTRETIREMENT BENEFITS | NOTE 8 - PENSIONS AND OTHER POSTRETIREMENT BENEFITS We offer defined benefit pension plans, defined contribution pension plans and OPEB plans, primarily consisting of retiree healthcare benefits, to most employees as part of a total compensation and benefits program. The defined benefit pension plans are noncontributory and benefits generally are based on a minimum formula or employees’ years of service and average earnings for a defined period prior to retirement. We offer retiree medical coverage to hourly retirees of our USW-represented mines. A new four-year agreement with the USW was entered into on October 12, 2018, and is retroactively effective from October 1, 2018 through September 30, 2022. The 2018 USW agreement established the set fixed monthly medical premiums for participants who retired prior to January 1, 2015. These fixed premiums will expire on December 31, 2020 and revert to increasing premiums based a cost-sharing formula thereafter. The agreement also provides for an OPEB cap that limits the amount of contributions that we have to make toward retiree medical insurance coverage for each retiree and spouse of a retiree per calendar year who retired on or after January 1, 2015. The amount of the annual OPEB cap is based upon the gross plan costs we incurred in 2014. The OPEB cap does not apply to surviving spouses. In lieu of retiree medical coverage, USW-represented employees hired after September 1, 2016 receive a 401(k) contribution of $0.50 per hour worked to a restricted Retiree Health Care Account. Beginning January 1, 2019, the hourly contribution rate increased to $0.60 per hour worked. In addition, we currently provide various levels of retirement health care and OPEB to some full-time employees who meet certain length of service and age requirements (a portion of which is pursuant to collective bargaining agreements). Most plans require retiree contributions and have deductibles, co-pay requirements and benefit limits. Most bargaining unit plans require retiree contributions and co-pays for medical and prescription drug coverage. There is a cap on our cost for medical coverage under the salaried plans. The annual limit applies to each covered participant and equals $7,000 for coverage prior to age 65, with the retiree’s participation adjusted based on the age at which the retiree’s benefits commence. We do not provide OPEB for most salaried employees hired after January 1, 1993. Retiree healthcare coverage is provided through programs administered by insurance companies whose charges are based on benefits paid. The following table summarizes the annual expense (income) recognized related to the retirement plans:

The pension and OPEB plans in 2018 experienced a net actuarial gain of $57.0 million and $29.4 million, respectively. The increase in discount rates due to market conditions was the primary driver, which resulted in gains of $75.7 million and $19.0 million for the pension and OPEB plans, respectively. The net gain was offset partially by losses of $21.7 million for the pensions plans and $2.3 million for the OPEB plans relating to demographic experience. The adoption of the new projection scale resulted in gains totaling $3.0 million for the pension plans and $0.8 million for the OPEB plans. Additionally, an update to the assumed per capita cost of medical benefits resulted in a gain of $11.9 million for the OPEB plans. The pension and OPEB plans in 2017 experienced a net actuarial loss of $54.6 million and $7.4 million, respectively. The decrease in discount rates due to market conditions was the primary driver, which resulted in losses of $46.1 million and $12.6 million for the pension and OPEB plans, respectively. The adoption of the new projection scale resulted in gains totaling $6.1 million for the pension plans and $1.9 million for the OPEB plans. The accumulated benefit obligation for all defined benefit pension plans was $896.8 million and $963.0 million at December 31, 2018 and 2017, respectively. Components of Net Periodic Benefit Cost

Assumptions The discount rate for determining PBO is determined individually for each plan as noted in the assumption chart below. The discount rates are determined by matching the projected cash flows used to determine the PBO and APBO to a projected yield curve of 1,101 Aa graded bonds in the 40 th to 90 th percentiles. These bonds are either noncallable or callable with make-whole provisions. On December 31, 2018, the assumed mortality improvement projection was changed from generational scale MP-2017 to generational scale MP-2018. The healthy mortality assumption remains the RP-2014 mortality tables with blue collar adjustments for the Iron Hourly Pension and Hourly OPEB plans, with white collar adjustments for the the Salaried OPEB Plan, and without adjustments for the Salaried and Ore Mining Pension Plans. On December 31, 2017, the assumed mortality improvement projection was changed from generational scale MP-2016 to generational scale MP-2017. Weighted-average assumptions used to determine benefit obligations at December 31 were:

Plan Assets Our financial objectives with respect to our pension and VEBA plan assets are to fully fund the actuarial accrued liability for each of the plans, to maximize investment returns within reasonable and prudent levels of risk, and to maintain sufficient liquidity to meet benefit obligations on a timely basis. Our investment objective is to outperform the expected return on assets assumption used in the plans’ actuarial reports over the life of the plans. The expected return on assets takes into account historical returns and estimated future long-term returns based on capital market assumptions applied to the asset allocation strategy. The expected return is net of investment expenses paid by the plans. In addition, investment performance is monitored on a quarterly basis by benchmarking to various indices and metrics for the one-, three- and five-year periods. The asset allocation strategy is determined through a detailed analysis of assets and liabilities by plan, which defines the overall risk that is acceptable with regard to the expected level and variability of portfolio returns, surplus (assets compared to liabilities), contributions and pension expense. The asset allocation review process involves simulating capital market behaviors including global asset class performance, inflation and interest rates in order to evaluate various asset allocation scenarios and determine the asset mix with the highest likelihood of meeting financial objectives. The process includes factoring in the current funded status and likely future funded status levels of the plans by taking into account expected growth or decline in the contributions over time. The asset allocation strategy varies by plan. The following table reflects the actual asset allocations for pension and VEBA plan assets as of December 31, 2018 and 2017, as well as the 2019 weighted average target asset allocations. Equity investments include securities in large-cap, mid-cap and small-cap companies located in the U.S. and worldwide. Fixed income investments primarily include corporate bonds and government debt securities.

Following is a description of the inputs and valuation methodologies used to measure the fair value of our plan assets. Equity Securities Equity securities classified as Level 1 investments include U.S. large-, small- and mid-cap investments and international equities. These investments are comprised of securities listed on an exchange, market or automated quotation system for which quotations are readily available. The valuation of these securities is determined using a market approach and is based upon unadjusted quoted prices for identical assets in active markets. Fixed Income Fixed income securities classified as Level 1 investments include bonds and government debt securities. These investments are comprised of securities listed on an exchange, market or automated quotation system for which quotations are readily available. The valuation of these securities is determined using a market approach and is based upon unadjusted quoted prices for identical assets in active markets. Also included in Fixed income is a portfolio of U.S. Treasury STRIPS, which are zero-coupon bearing fixed income securities backed by the full faith and credit of the U.S. government. The securities sell at a discount to par because there are no incremental coupon payments. STRIPS are not issued directly by the Treasury but rather are created by a financial institution, government securities broker or government securities dealer. Liquidity on the issue varies depending on various market conditions; however, in general the STRIPS market is slightly less liquid than that of the U.S. Treasury Bond market. The STRIPS are priced daily through a bond pricing vendor and are classified as Level 2. Hedge Funds Hedge funds are alternative investments comprised of direct or indirect investment in offshore hedge funds with an investment objective to achieve equity-like returns with one half the volatility of equities and moderate correlation. The valuation techniques used to measure fair value attempt to maximize the use of observable inputs and minimize the use of unobservable inputs. Considerable judgment is required to interpret the factors used to develop estimates of fair value. Valuations of the underlying investment funds are obtained and reviewed. The securities that are valued by the funds are interests in the investment funds and not the underlying holdings of such investment funds. Thus, the inputs used to value the investments in each of the underlying funds may differ from the inputs used to value the underlying holdings of such funds. Hedge funds are valued monthly and recorded on a one-month lag. Private Equity Funds Private equity funds are alternative investments that represent direct or indirect investments in partnerships, venture funds or a diversified pool of private investment vehicles (fund of funds). Investment commitments are made in private equity funds based on an asset allocation strategy, and capital calls are made over the life of the funds to fund the commitments. As of December 31, 2018, remaining commitments total $44.2 million for both our pension and OPEB plans. Committed amounts are funded from plan assets when capital calls are made. Investment commitments are not pre-funded in reserve accounts. Private equity investments are valued quarterly and recorded on a one-quarter lag. For alternative investment values reported on a lag, current market information is reviewed for any material changes in values at the reporting date. Capital distributions for the funds do not occur on a regular frequency. Liquidation of these investments would require sale of the partnership interest. Structured Credit Structured credit investments are alternative investments comprised of collateralized debt obligations and other structured credit investments that are priced based on valuations provided by independent, third-party pricing agents, if available. Such values generally reflect the last reported sales price if the security is actively traded. The third-party pricing agents may also value structured credit investments at an evaluated bid price by employing methodologies that utilize actual market transactions, broker-supplied valuations or other methodologies designed to identify the market value of such securities. Structured credit investments are valued monthly and recorded on a one-month lag. For alternative investment values reported on a lag, current market information is reviewed for any material changes in values at the reporting date. Historically, redemption requests have been considered quarterly, subject to notice of 90 days, although the advisor is currently only requiring notice of 65 days. Real Estate The real estate portfolio for the pension plans is an alternative investment primarily comprised of two funds with strategic categories of real estate investments. All real estate holdings are appraised externally at least annually, and appraisals are conducted by reputable, independent appraisal firms that are members of the Appraisal Institute. All external appraisals are performed in accordance with the Uniform Standards of Professional Appraisal Practices. The property valuations and assumptions about each property are reviewed quarterly by the investment advisor and values are adjusted if there has been a significant change in circumstances relating to the property since the last external appraisal. The fair value of one of the funds is updated monthly, and there is no lag in reported value. Redemption requests are considered on a quarterly basis, subject to notice of 45 days. The real estate fund of funds investment for the Empire-Tilden, Hibbing and United Taconite VEBA plans invests in pooled investment vehicles that in turn invest in commercial real estate properties. Valuations are performed quarterly and financial statements are prepared on a semi-annual basis, with annual audited statements. Asset values for this fund are reported with a one-quarter lag, and current market information is reviewed for any material changes in values at the reporting date. Withdrawals are permitted on the last business day of each quarter subject to a 65-day prior written notice. Pension The fair value of our pension plan assets by asset category is as follows:

The Company currently has no intention to shut down, terminate or withdraw from any of its employee benefit plans.
