"Revenue Recognition
Revenues and related costs on construction contracts are recognized using the “percentage of completion method” of accounting in accordance with ASC 605-35, Accounting for Performance of Construction-Type and Certain Production Type Contracts (“ASC 605-35”). Under this method, contract revenues and related expenses are recognized over the performance period of the contract in direct proportion to the costs incurred as a percentage of total estimated costs for the entirety of the contract. Costs include direct material, direct labor, subcontract labor and any allocable indirect costs. All un-allocable indirect costs and corporate general and administrative costs are charged to the periods as incurred. However, in the event a loss on a contract is foreseen, the Company will recognize the loss as it is determined.
Revisions in cost and profit estimates during the course of the contract are reflected in the accounting period in which the facts, which require the revision, become known. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined. Changes in job performance, job conditions, and estimated profitability, including those arising from contract penalty provisions, and final contract settlements may result in revisions to costs and income and are recognized in the period in which the revisions are determined.
The Asset, “Costs and estimated earnings in excess of billings”, represents revenues recognized in excess of amounts billed on contracts in progress. The Liability, “Billings in excess of costs and estimated earnings”, represents billings in excess of revenues recognized on contracts in progress. At March 31, 2015 and 2014, the costs in excess of billings balance was $1,564,543 and $1,276,677, and the billings in excess of costs balance was $1,143,189 and $891,633, respectively.
Contract receivables are recorded on contracts for amounts currently due based upon progress billings, as well as retention, which are collectible upon completion of the contracts. Accounts payable to material suppliers and subcontractors are recorded for amounts currently due based upon work completed or materials received, as are retention due subcontractors, which are payable upon completion of the contract. General and administrative expenses are charged to operations as incurred and are not allocated to contract costs."
