Notes to Financial Statements
Significant Accounting Policies [Text Block]	2. Our accompanying consolidated financial statements have been prepared on the basis of accounting principles generally accepted in the United States of America (“U.S. GAAP”). The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Significant estimates include acquisition purchase price allocations, the fair value of goodwill, the realization of deferred tax assets and liabilities, acquisition-related liabilities, fair value of stock-based compensation for equity awards granted, and assets and liabilities for pension and postretirement benefits. Actual results may 2021 2021 On October 28, 2022, 205 20, Discontinued Operations 205 20” fourth 2022 205 20. Significant accounting policies include the following: (a) Intercompany Accounts and Transactions The consolidated financial statements include all of our accounts. All intercompany accounts and transactions have been eliminated. (b) Revenue Recognition The following describes our primary types of revenues and the applicable revenue recognition policies. We recognize revenues through recurring and non-recurring long-term agreements (generally one five Hosted Subscriptions We offer two first not no not 606. The second may no not 606. Subscriptions are generally paid in advance of rendering services either quarterly or annually upon commencement of the subscription period, which is usually for one Advisory/Consulting Services We provide certain discrete project based advisory/consulting services, which are recognized over time by measuring the progress toward complete satisfaction of the performance obligation, based on the input method of consulting hours worked; this aligns with the results achieved and value transferred to our customer. The hours consumed are most reflective of the measure of progress towards satisfying the performance obligation, as the resources hours worked directly tie to the progress of the services to be provided. In general, they are billed over the course of the project. Transactional Solutions Certain solutions are also paid for by customers on a transactional basis. We recognize these revenues as the solutions are delivered or services performed at a point in time. In general, our customers are billed monthly at the end of each month. (c) Deferred Revenues We invoice our customers in annual, quarterly, monthly, or milestone installments.

Retirement Benefits [Text Block]	18. We have a frozen qualified defined benefit pension plan for certain of our employees through membership in the Pension Plan for Insurance Organizations (the “Pension Plan”), a multiple-employer trust. Prior to the freeze, we applied a cash balance formula to determine future benefits. Under the cash balance formula, each participant has an account, which was credited annually based on salary rates determined by years of service, as well as the interest earned on the previous year-end cash balance. We also have a non-qualified frozen supplemental cash balance plan (“SERP”) for certain employees. Our SERP is funded from our general assets. W e contributed $0.8 million to our SERP in 2022 and $0.7 million in 2021 , respectively, and expect to contribute $0.8 million in 2023. Our Pension Plan’s funding policy is to contribute annually at an amount between the minimum funding requirements set forth in the Employee Retirement Income Security Act of 1974 No d for 2022 and 2023, We also provide certain healthcare and life insurance benefits for both active and retired employees.

The expected return for each investment category within the target investment allocation is developed using average historical rates of return for each targeted investment category, considering the projected cash flow of our Pension Plan. The difference between this expected return and the actual return on plan assets is generally deferred and recognized over subsequent periods through future net periodic benefit costs. We believe that the use of the average historical rates of returns is consistent with the timing and amounts of expected contributions to the plans and benefit payments to plan participants.

Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Our accompanying consolidated financial statements have been prepared on the basis of accounting principles generally accepted in the United States of America (“U.S. GAAP”). The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Significant estimates include acquisition purchase price allocations, the fair value of goodwill, the realization of deferred tax assets and liabilities, acquisition-related liabilities, fair value of stock-based compensation for equity awards granted, and assets and liabilities for pension and postretirement benefits.
