RETIREMENT BENEFIT PLANS [Abstract] |
RETIREMENT BENEFIT PLANS | 10. Retirement Benefit Plans The Company has non-contributory defined benefit pension plans covering most U.S. employees. Plan benefits are generally based upon age at retirement, years of service and, for its salaried plan, the level of compensation. The Company also sponsors unfunded non-qualified supplemental retirement plans that provide certain former officers with benefits in excess of limits imposed by federal tax law. The Company also provides health care and life insurance for retired salaried employees in the United States who meet specific eligibility requirements. Components of the net periodic benefit cost of the Company’s pension benefit plans were as follows:

Assumptions used to determine the projected benefit obligations for the Company’s pension benefit plans and postretirement benefit plan for the fiscal year indicated were as follows:
|  | 2015 |  | 2014
Discount rate |  |  |  |  |  |

At January 2, 2016 and January 3, 2015, the accumulated benefit obligation for all qualified and nonqualified defined benefit pension plans was $83,433,339 and $84,714,136, respectively. Information for the under-funded pension plans with a projected benefit obligation and an accumulated benefit obligation in excess of plan assets:
|  | 2015 |  | 2014 |
Number of plans |  |  | 6 |  |  | 6 |
Projected benefit obligation |  | $ | 87,427,769 |  | $ | 90,516,922 |
Accumulated benefit obligation |  |  | 83,433,339 |  |  | 84,714,136 |
Fair value of plan assets |  |  | 63,122,843 |  |  | 64,352,110 |
Net amount recognized in accrued benefit liability |  |  | (24,304,926 | ) |  | (26,164,812 | )
Estimated future benefit payments to participants of the Company’s pension plans are $3.4 million in 2016, $3.6 million in 2017, $3.8 million in 2018, $4.1 million in 2019, $4.4 million in 2020 and a total of $26.2 million from 2021 through 2025. Estimated future benefit payments to participants of the Company’s postretirement plan are $118,000 in 2016, $118,000 in 2017, $117,000 in 2018, $117,000 in 2019, $117,000 in 2020 and a total of $577,000 from 2021 through 2025. The Company expects to make cash contributions to its qualified pension plans of approximately $3.1 million and to its postretirement plan of approximately $118,000 in 2016. We consider a number of factors in determining and selecting assumptions for the overall expected long-term rate of return on plan assets. We consider the historical long-term return experience of our assets, the current and expected allocation of our plan assets, and expected long-term rates of return. We derive these expected long-term rates of return with the assistance of our investment advisors and generally base these rates on a 10-year horizon for various asset classes and consider the expected positive impact of active investment management. We base our expected allocation of plan assets on a diversified portfolio consisting of domestic and international equity securities and fixed income securities. We consider a variety of factors in determining and selecting our assumptions for the discount rate at the end of the year. In 2015 we developed each plan’s discount rate with the assistance of our actuaries by matching expected future benefit payments in each year to the corresponding spot rates from the Citigroup Pension Liability Yield Curve, comprised of high quality (rated AA or better) corporate bonds. Prior to 2015, we used the same process to determine each individual plan’s discount rate, but the average of these rates was used to determine a single rate for all plans. The fair values of the company’s pension plans assets at January 2, 2016 and January 3, 2015, utilizing the fair value hierarchy discussed in Note 2, follow:

(d) | The Russell International Fund with Active Currency seeks to provide long-term growth of Capital. Aims to outperform the Russell Development ex-U.S. Large Cap Index Net while managing volatility and maintaining diversification similar to the index over a full market cycle.

Employs multiple managers with distinct investment styles, which are intended to be complementary. Seeks to capitalize on the stock selection abilities of its active manager.

(f) | The Russell Fixed Income I Fund is designed to provide current income and capital appreciation through a variety of diversified strategies. The Fund seeks favorable returns comparable to the broad fixed income market, as measured by the Barclays U.S. Aggregate Bond Index. The fund primarily invests in fixed income securities representing diverse sectors and maturities. Advisors use diversified strategies including sector rotation, modest interest rate timing, security selection and tactical use of high yield and emerging market bonds. It is actively managed with multiple advisors employing distinct yet complementary strategies and different technologies to insure prudent diversification over a broad spectrum of investments.
(g) | The Target Duration LDI Fixed Income Funds seek to outperform their respective Barclays-Russell LDI Indexes over a full market cycle. These Funds invest primarily in investment grade corporate bonds that closely match those found in discount curves used to value U.S. pension liabilities. They seek to provide additional incremental return through modest interest rate timing, security selection and tactical use of non-credit sectors. Generally for use in combination with other bond funds to gain additional credit exposure, with the goal of reducing the mismatch between a plan’s assets and liabilities.
(h) | The STRIPS (Separate Trading of Registered Interest and Principal of Securities) Funds seek to provide duration and Treasury exposure by investing in an optimized subset of the STRIPS universe with a similar duration profile as the Barclays U.S. Treasury STRIPS 10-11 year, 16-16 year or 28-29 year Index. These passively managed funds are generally used with other bond funds to add additional duration to the asset portfolio. This will help reduce the mismatch between a plan’s assets and liabilities.
(i) | The Russell Long Duration Fixed Income Fund seeks to outperform the Barclays Capital Long Credit Index over a full market cycle. The fund seeks to provide current income, and as a secondary objective, capital appreciation through diversified strategies including sector rotation, modest interest rate timing, security selection and tactical use of high yield and emerging market bonds. The fund will generally be used in combination with other bond funds, with the goal of reducing the mismatch between a plan’s assets and liabilities. In January 2015, the Trustee of the plan sold all of the assets of this fund. The proceeds were invested in the LDI Target funds and the STRIPS funds as of the end of 2015.
The investment portfolio contains a diversified blend of common stocks, bonds, cash equivalents, and other investments, which may reflect varying rates of return. The investments are further diversified within each asset classification. The portfolio diversification provides protection against a single security or class of securities having a disproportionate impact on aggregate performance. The Company has elected to change its investment strategy to better match the assets with the underlying plan liabilities. Currently, the long-term target allocations for plan assets are 50% in equities and 50% in fixed income although the actual plan asset allocations may be within a range around these targets. The actual asset allocations are reviewed and rebalanced on a periodic basis to maintain the target allocations. It is expected that, as the funded status of the plans improves, more assets will be invested in long-duration fixed income instruments.

The Level 3 assets described above are the only assets of the postretirement plan, and thus have no impact on any Level 1 or Level 2 assets. For measurement purposes relating to the postretirement benefit plan, the life insurance cost trend rate is 1%. The health care cost trend rate for participants retiring after January 1, 1991 is nil; no increase in that rate is expected because of caps placed on benefits. The health care cost trend rate is expected to remain at 4.5% for participants after the year 2000. A one-percentage-point change in assumed health care cost trend rates would have the following effects on the postretirement benefit plan:
|  | 1-Percentage Point |  |
|  | Increase |  | Decrease |  |
Effect on total of service and interest cost components |  | $ | 71,520 |  | $ | (57,039 | )
Effect on postretirement benefit obligation |  | $ | — |  | $ | — |
