Employee Benefits [Abstract]  
Employee benefits Employee benefits
The Company operates various post-employment plans, including defined benefit and defined contribution pension plans as well as other benefit plans for its employees.
DEFINED BENEFIT PLANS
The Company operates defined benefit pension plans primarily for the benefit of employees in the U.K., Germany and France, with smaller plans in other countries. The benefits are based on pensionable salary and years of service and are funded with assets held in separate funds.
The defined benefit plans expose the Company to interest risk, inflation risk, longevity risk, currency risk and market investment risk.
The following description focuses mainly on plans registered in the U.K., France and Germany:
U.K.
In the U.K., the Company has three defined benefit pension plans, the CMG U.K. Pension Scheme, the Logica U.K. Pension & Life Assurance Scheme and the Logica Defined Benefit Pension Plan.
The CMG U.K. Pension Scheme is closed to new members and is closed to further accrual of rights for existing members. The Logica U.K. Pension & Life Assurance Scheme is still open but only for employees who come from the civil service with protected pensions. The Logica Defined Benefit Pension Plan was created to mirror the Electricity Supply Pension Scheme and was created for employees that worked for National Grid and Welsh Water with protected benefits.
Both the Logica U.K. Pension & Life Assurance Scheme and the Logica Defined Benefit Pension Plan are employer and employee based contribution plans.
The trustees are the custodians of the defined benefit pension plans and are responsible for the plan administration, including investment strategies. The trustees review periodically the investment and the asset allocation policies. As such, the CMG U.K. Pension Scheme policy is to target an allocation up to a maximum of 45% to return-seeking assets such as equities; the Logica U.K. Pension & Life Assurance Scheme policy is to invest 15% of the scheme assets in equities and 85% in bonds; and the Logica Defined Benefit Pension Plan policy is to invest 15% of the plan assets in equities and 85% in bonds.
The U.K. Pensions Act 2004 requires that full formal actuarial valuations are carried out at least every three years to determine the contributions that the Company should pay in order for the plan to meet its statutory objective, taking into account the assets already held. In the interim years, the trustees need to obtain estimated funding updates unless the scheme has less than 100 members in total.
The latest funding actuarial valuations of the three defined benefit pension plans described above were being performed as at September 30, 2021 and the results were finalized during the year ended September 30, 2022 with the following recommendations:
The actuarial valuation of the CMG U.K. Pension Scheme reported a surplus of $34,707,000. It specified that no supplementary contributions were required in order to reach the plan funding objectives. During fiscal 2022, the Company contributed an amount of $693,000 to cover administration expenses; and
The actuarial valuation of the Logica U.K. Pension & Life Assurance Scheme reported a surplus of $85,000. It specified that no supplementary contributions were required in order to reach the plan funding objectives. During fiscal 2022, the Company contributed an amount of $314,000 to cover service costs; and
The actuarial valuation of the Logica Defined Benefit Pension Plan reported a surplus of $17,819,000. It specified that no supplementary contributions were required in order to reach the plan funding objectives. Since November 30, 2019, the Company did not contribute to the plan.

DEFINED BENEFIT PLANS (CONTINUED)
France
In France, the retirement indemnities are provided in accordance with the Labour Code. Upon retirement, employees receive an indemnity, depending on the salary and seniority in the Company, in the form of a lump-sum payment.
Germany
In Germany, the Company has numerous defined benefit pension plans which are all closed to new members. In the majority of the plans, upon retirement of employees, the benefits are in the form of a monthly pension and in a few plans, the employees receive an indemnity in the form of a lump-sum payment.There are no mandatory funding requirements. The plans are funded by the contributions made by the Company. In some plans, insurance policies are taken out to fund retirement benefit plans. These do not qualify as plan assets and are presented as reimbursement rights, unless they are part of a reinsured support fund or are pledged to the employees.

Actuarial assumptions (continued)
Assumptions regarding future mortality are set based on actuarial advice in accordance with published statistics and experience in each country. Mortality assumptions for the most significant countries are based on the following post-retirement mortality tables for the year ended September 30, 2022: (1) U.K.: 100% S2PxA (year of birth) plus CMI_2020 projections with 1.25% p.a. minimum long term improvement rate, (2) Germany: Heubeck RT2018G and (3) France: INSEE TVTD 2016-2018.

DEFINED BENEFIT PLANS (CONTINUED)
The Company expects to contribute $7,257,000 to defined benefit plans during the next year, of which $329,000 relates to the U.K. plans, and $6,928,000 relates to the other plans. The contributions will include new benefit accruals.
DEFINED CONTRIBUTION PLANS
The Company also operates defined contribution pension plans. In some countries, contributions are made into the state pension plans. The pension cost for defined contribution plans amounted to $226,079,000 in 2022 ($224,010,000 in 2021).
In addition, in Sweden, the Company contributes to a multi-employer plan, Alecta SE (Alecta) pension plan, which is a defined benefit pension plan. This pension plan is classified as a defined contribution plan as sufficient information is not available to use defined benefit accounting. Alecta lacks the possibility of establishing an exact distribution of assets and provisions to the respective employers. The Company’s proportion of the total contributions to the plan is 0.48% and the Company’s proportion of the total number of active members in the plan is 0.47%.
Alecta uses a collective funding ratio to determine the surplus or deficit in the pension plan. Any surplus or deficit in the plan will affect the amount of future contributions payable. The collective funding is the difference between Alecta’s assets and the commitments to the policy holders and insured individuals. The collective funding ratio is normally allowed to vary between 125% and 175%. As at September 30, 2022, Alecta collective funding ratio was 189% (169% in 2021). The plan expense was $29,539,000 in 2022 ($31,807,000 in 2021). The Company expects to contribute $20,131,000 to the plan during the next year.
OTHER BENEFIT PLANS
As at September 30, 2022, the deferred compensation liability totaled $81,452,000 ($91,943,000 as at September 30, 2021) (Note 15) and the deferred compensation assets totaled $71,863,000 ($81,633,000 as at September 30, 2021) (Note 11). The deferred compensation liability is mainly related to plans covering some of its U.S. and German management. Some of the plans include assets that will be used to fund the liabilities.
For the deferred compensation plan in the U.S., a trust was established so that the plan assets could be segregated; however, the assets are subject to the Company’s general creditors in the case of bankruptcy. The assets composed of investments vary with employees’ contributions and changes in the value of the investments. The change in liabilities associated with the plan is equal to the change of the assets. The assets in the trust and the associated liabilities totaled $71,863,000 as at September 30, 2022 ($81,245,000 as at September 30, 2021).
