RETIREMENT FUND AND PROFIT SHARING PLAN [Abstract] |
RETIREMENT FUND AND PROFIT SHARING PLAN | 13. RETIREMENT FUND AND PROFIT SHARING PLAN The Company maintains the Bel Fuse Inc. Employees' Savings Plan, a defined contribution plan that is intended to meet the applicable requirements for tax-qualification under sections 401(a) and (k) of the Internal Revenue Code of 1986, as amended (the "Code"). The Employees' Savings Plan allows eligible employees to voluntarily contribute a percentage of their eligible compensation, subject to Code limitations, which contributions are matched by the Company in an amount equal to 100% of the first 1% of compensation contributed by participants, and 50% of the next 5% of compensation contributed by participants. Effective January 1, 2017, the Company's matching contribution is made in the form of Bel Fuse Inc. Class A common stock. For plan years beginning on January 1, 2012 through December 31, 2016, the Company's matching contributions were made in cash. Prior to January 1, 2012, the Company's matching and profit sharing contributions were made in the form of shares of Bel Fuse Inc. Class A and Class B common stock. The expense for the years ended December 31, 2017, 2016 and 2015 amounted to $1.2 million, $1.1 million and $1.2 million, respectively. As of December 31, 2017, the plan owned 67,891 and 144,276 shares of Bel Fuse Inc. Class A and Class B common stock, respectively. The Company's subsidiaries in Asia have a retirement fund covering substantially all of their Hong Kong based full-time employees. Eligible employees contribute up to 5% of salary to the fund. In addition, the Company must contribute a minimum of 5% of eligible salary, as determined by Hong Kong government regulations. The Company currently contributes 7% of eligible salary in cash or Company stock. The expense for the years ended December 31, 2017, 2016 and 2015 amounted to approximately $0.3 million in each year. As of December 31, 2017, the plan owned 3,323 and 17,342 shares of Bel Fuse Inc. Class A and Class B common stock, respectively. The Company maintains a SERP, which is designed to provide a limited group of key management and other key employees of the Company with supplemental retirement and death benefits. Participants in the SERP are selected by the Compensation Committee of the Board of Directors. The SERP initially became effective in 2002 and was amended and restated in April 2007 to conform with applicable requirements of Section 409A of the Internal Revenue Code and to modify the provisions regarding benefits payable in connection with a change in control of the Company. The Plan is unfunded. Benefits under the SERP are payable from the general assets of the Company, but the Company has established a rabbi trust which includes certain life insurance policies in effect on participants as well as other investments to partially cover the Company's obligations under the Plan. See Note 6, "Other Assets," for further information on these assets. The benefits available under the SERP vary according to when and how the participant terminates employment with the Company. If a participant retires (with the prior written consent of the Company) on his normal retirement date (65 years old, 20 years of service, and 5 years of Plan participation), his normal retirement benefit under the Plan would be annual payments equal to 40% of his average base compensation (calculated using compensation from the highest five consecutive calendar years of Plan participation), payable in monthly installments for the remainder of his life. If a participant retires early from the Company (55 years old, 20 years of service, and five years of Plan participation), his early retirement benefit under the Plan would be an amount (i) calculated as if his early retirement date were in fact his normal retirement date, (ii) multiplied by a fraction, with the numerator being the actual years of service the participant has with the Company and the denominator being the years of service the participant would have had if he had retired at age 65, and (iii) actuarially reduced to reflect the early retirement date. If a participant dies prior to receiving 120 monthly payments under the Plan, his beneficiary would be entitled to continue receiving benefits for the shorter of (i) the time necessary to complete 120 monthly payments or (ii) 60 months. If a participant dies while employed by the Company, his beneficiary would receive, as a survivor benefit, an annual amount equal to (i) 100% of the participant's annual base salary at date of death for one year, and (ii) 50% of the participant's annual base salary at date of death for each of the following four years, each payable in monthly installments. The Plan also provides for disability benefits, and a forfeiture of benefits if a participant terminates employment for reasons other than those contemplated under the Plan. The expense related to the Plan for the years ended December 31, 2017, 2016 and 2015 amounted to $1.7 million, $1.6 million and $1.5 million, respectively. Net Periodic Benefit Cost The net periodic benefit cost related to the SERP consisted of the following components during the years ended December 31, 2017, 2016 and 2015:

The Company has recorded the 2017 and 2016 underfunded status as a long-term liability on the consolidated balance sheets. The accumulated benefit obligation for the SERP was $16.1 million as of December 31, 2017 and $13.8 million as of December 31, 2016. The aforementioned company-owned life insurance policies and marketable securities held in a rabbi trust had a combined value of $14.0 million and $12.7 million at December 31, 2017 and 2016, respectively. See Note 6, "Other Assets," for additional information on these investments. The estimated net loss and prior service cost for the defined benefit pension plan that will be amortized from accumulated other comprehensive loss into net periodic benefit cost over the next fiscal year is $0.4 million. The Company expects to make contributions of $0.3 million to the SERP in 2018. The Company had no net transition assets or obligations recognized as an adjustment to other comprehensive income and does not anticipate any plan assets being returned to the Company during 2018, as the plan has no assets. The following benefit payments, which reflect expected future service, are expected to be paid:
