Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies Disclosure [Text Block]	11. COMMITMENTS AND CONTINGENCIES Legal Matters From time to time we are a party to various claims, lawsuits and other legal proceedings that arise in the ordinary course of business. We maintain various insurance coverages to minimize financial risk associated with these proceedings. None of these proceedings, separately or in the aggregate, are expected to have a material adverse effect on our financial position, results of operations or cash flows. With respect to all such proceedings, we record reserves when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. We expense routine legal costs related to these proceedings as they are incurred. On June 22, 2021, the United States Department of Labor Wage and Hour Division (the “DOL”) notified IES Residential, Inc. (“IESR”), a wholly-owned subsidiary of the Company, that the DOL had commenced an administrative investigation of IESR’s compliance with laws regulating employee wage payment. The inquiry concerned record keeping with respect to certain Arizona employees who are paid on a piece rate basis. We entered into a settlement with the DOL in November 2022, resolving this matter. Costs associated with this matter, which did not have a material impact on our results of operations, were accrued as a liability as of September 30, 2022. In the course of performing work as a subcontractor, from time to time we may be involved in projects which are the subject of contractual disputes between the general contractor and project owner, or between us and the general contractor. In such cases, payment of amounts owed to us by the general contractor may be delayed as contractual disputes are resolved through mediation, arbitration, or litigation. Such disputes may cause us to incur legal fees and other expenses to enforce our contractual rights, and we may not prevail in recovering all amounts to which we believe we are contractually entitled. At September 30, 2022, we had an aggregate $10,451 of trade accounts receivable where payment had been delayed as a result of contractual disputes and against which we had recorded a reserve of $3,095. During the quarter ended December 31, 2022, we collected $5,140 related to these receivables. We believe that we are contractually entitled to the remaining amounts owed to us, and intend to vigorously pursue recovery. At December 31, 2022, the remaining book value of receivables and retainage related to these contractual disputes, net of associated reserves, was $2,389. Risk Management We retain the risk for workers’ compensation, employer’s liability, automobile liability, construction defects, general liability and employee group health claims, as well as pollution coverage, resulting from uninsured deductibles per accident or occurrence which are generally subject to annual aggregate limits. Our general liability program provides coverage for bodily injury and property damage. In many cases, we insure third parties, including general contractors, as additional insured parties under our insurance policies. Losses are accrued based upon our known claims incurred and an estimate of claims incurred but not reported. As a result, many of our claims are effectively self-insured. Many claims against our insurance are in the form of litigation. At December 31, 2022 and September 30, 2022, we had $7,695 and $7,693, respectively, accrued for self-insurance liabilities. Because the reserves are based on judgment and estimates and involve variables that are inherently uncertain, such as the outcome of litigation and an assessment of insurance coverage, there can be no assurance that the ultimate liability will not be higher or lower than such estimates or that the timing of payments will not create liquidity issues for the Company. Some of the underwriters of our casualty insurance program require us to post letters of credit as collateral. This is common in the insurance industry. To date, we have not had a situation where an underwriter has had reasonable cause to effect payment under a letter of credit. At December 31, 2022 and September 30, 2022, $5,693 and $3,878, respectively, of our outstanding letters of credit was utilized to collateralize our insurance program. Surety As of December 31, 2022, the estimated cost to complete our bonded projects was approximately $77,855. We evaluate our bonding requirements on a regular basis, including the terms offered by our sureties. We believe the bonding capacity presently provided by our current sureties is adequate for our current operations and will be adequate for our operations for the foreseeable future. Other Commitments and Contingencies Some of our customers and vendors require us to post letters of credit, or provide intercompany guarantees, as a means of guaranteeing performance under our contracts and ensuring payment by us to subcontractors and vendors. If our customer has reasonable cause to effect payment under a letter of credit, we would be required to reimburse our creditor for the letter of credit. From time to time we may enter into firm purchase commitments for materials, such as copper or aluminum wire, which we expect to use in the ordinary course of business. These commitments are typically for terms of less than one year and require us to buy minimum quantities of materials at specific intervals at a fixed price over the term. As of December 31, 2022, we had commitments of $6,936 outstanding under agreements to purchase copper wire and other materials over the next 12 months in the ordinary course of business.
