Retirement Benefits [Abstract] |
Pension and Profit Sharing | 6. Pension and Profit Sharing United States employees, hired prior to July 1, 1993, are covered by a funded, defined benefit pension plan. The benefits of this pension plan are based on years of service and the average compensation of the highest three consecutive years during the last ten years of employment. In December 1995, the Company's Board of Directors approved an amendment to the United States pension plan that terminated all future benefit accruals as of February 1, 1996, without terminating the pension plan. The Company’s funding policy with respect to its qualified plan is to contribute at least the minimum amount required by applicable laws and regulations. In 2017, the Company did not contribute to the plan. The plan asset weighted average allocation at December 31, 2017 and December 31, 2016, by asset category, were as follows:
Asset Category | 2017 | 2016
Equity Securities | 67% | 65%
Fixed Income Securities | 32% | 32%
Other Securities / Investments | 1% | 3%
Total | 100% | 100%
The Company’s investment policy for the pension plan is to minimize risk by balancing investments between equity securities and fixed income securities. Plan funds are invested in long-term obligations with a history of moderate to low risk. The pension plan asset information included below is presented at fair value. ASC 820 establishes a framework for measuring fair value and requires disclosures about assets and liabilities measured at fair value. The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three levels as follows:
| · | Level 1 – Inputs to the valuation methodology based on unadjusted quoted market prices in active markets that are accessible at the measurement date.
| · | Level 2 – Inputs to the valuation methodology that include quoted market prices that are not considered to be active or financial instruments for which all significant inputs are observable, either directly or indirectly.
| · | Level 3 – Inputs to the valuation methodology are unobservable and significant to the fair value measurement.
The following tables present the pension plan assets by level within the fair value hierarchy as of December 31, 2017 and 2016:

The Company employs a building block approach in determining the long-term rate of return for plan assets. Historical markets are studied and long-term historical relationships between equity securities and fixed income securities are preserved consistent with the widely-accepted capital market principle that assets with higher volatility generate higher returns over the long run. Our expected 6% long-term rate of return on plan assets is determined based on long-term historical performance of plan assets, current asset allocation and projected long-term rates of return. The following table discloses the change recorded in other comprehensive income related to benefit costs:
|  | 2017 |  | 2016
Balance at beginning of the year |  | $ | 1,130,815 |  |  | $ | 1,426,030 |
