Defined Benefit Plan
The Company has a defined benefit plan in the U.K., the Harlan Laboratories UK Limited Occupational Pension Scheme (the "Pension Plan"), which operated through April 2012. As of April 30, 2012, the accumulation of plan benefits of employees in the Pension Plan was permanently suspended and therefore the Pension Plan was curtailed.
The following tables summarize the changes in the benefit obligation funded status of the Pension Plan and amounts reflected in the Company’s consolidated balance sheets as of September 30, 2025 and 2024.

In July 2024, the U.K. Court of Appeal upheld a ruling in the matter of Virgin Media Limited v NTL Pension Trustees II Limited, a decision that the Company was not a party to or involved in, that certain historical amendments for contracted out defined benefit schemes were invalid if they were not accompanied by the correct actuarial confirmation. The U.K. Government has now announced proposals to legislate in response to this case.  The Company and its U.K. pension scheme trustee will continue to review this development and consider whether this decision has any implications for the Pension Plan subject to completion of the legislative process in the UK and the detail of any relevant legislation once it is known.
The net periodic benefit costs, which are presented within general and administrative expenses, under the Pension Plan were as follows:

Gains (Losses) Related to Changes in Benefit Obligation
The actuarial losses during the twelve months ended September 30, 2025 were primarily due to the increased discount rate assumption. The actuarial gains during the twelve months ended September 30, 2024 were primarily due to decreased discount rate assumptions as a result of interest rate trends in the U.K. The actuarial gains during the twelve months ended
September 30, 2023 were due to a significant increase in the discount rate as a result of rising interest rates in the U.K. The remainder of the changes in both periods were cumulative translation adjustments and gains in asset values.
The Company uses the corridor approach when amortizing actuarial gains and losses. Under the corridor approach, the actuarial gains and actuarial losses in excess of 10% of the greater of the beginning of year benefit obligation or market related value of plan assets are amortized over a fixed period of 10 years. This is a shorter period than the expected average life expectancy of the members in the Plan.
Assumptions
The major assumptions used in determining the net periodic benefit costs for the fiscal years ended September 30, 2025, 2024 and 2023:
Fiscal Year Ended
September 30,		Fiscal Year Ended
September 30,		Fiscal Year Ended
September 30,
202520242023
Discount rate5.04%5.67%5.33%
Expected return on plan assets5.20%4.85%4.96%
Our expected return on plan asset assumption, used to determine benefit obligations, is based on historical long-term rates of return on investments. Many factors, including portfolio allocation, target portfolio allocation and expected expenses, are evaluated during the process of determining the expected return on plan assets.
Discount rates were determined for the defined benefit retirement plan at the measurement date to reflect the yield of a portfolio of high-quality bonds matched against the timing and amounts of projected future benefit payments.
At September 30, 2025, we are decreasing our long-term rate of return assumption to 5.10% for pension plan assets. The major assumptions used in determining benefit obligations were as follows:

Pension Plan Assets
The Company maintains target allocation percentages among various asset categories based on an investment policy designed to achieve long-term objectives of return, while mitigating downside risk and considering expected cash flows. The Company’s investment policy is reviewed from time to time to ensure consistency with long-term objectives.
