| EBP, Accounting Policy [Line Items] | |
| EBP, Basis of Accounting | Basis of Accounting — The accompanying financial statements have been prepared on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”).
|
| EBP, Use of Estimate | Use of Estimates — The preparation of financial statements in conformity with U.S. GAAP requires the Plan to make estimates and assumptions that affect the reported amounts of net assets available for benefits and changes therein. Actual results could differ from those estimates.
|
| EBP, Payment to Participant | Payment of Benefits — Benefits are recorded when paid.
|
| EBP, Investment | Investments and Revenue Recognition — The Plan’s investments are stated at fair value. Money market and other mutual funds are stated at their quoted market prices. All Plan investments that are classified within the fair value hierarchy are actively traded in an open market to support classification of the fair value measurement as Level 1. The Plan's investments in collective investment trusts are valued using the net asset value quoted by the trustee, which is the readily determinable fair value and the basis for current transactions. The net asset value is calculated by each fund's manager based on the fair value, as determined by the investment provider, of the underlying assets held by the fund less its liabilities. Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on an accrual basis. Dividends are recorded on the ex-dividend date. Net appreciation (depreciation) includes the Plan’s realized and unrealized gains and losses on investments bought and sold as well as those held during the year.
|
| EBP, Risk and Uncertainty | Risks and Uncertainties — Investment securities, in general, are exposed to various risks, such as interest rate, credit, and overall market volatility. Due to the level of risk associated with certain investment securities, it is reasonably possible that changes in the value of investment securities will occur in the near term, and those changes could materially affect the amounts reported in the Statements of Net Assets Available for Benefits.
