Based on historical payment trends, we expect that these customers will take advantage of these early payment discounts. The cost of these discounts is reported as a reduction to the transaction price. If the actual discounts differ from those estimated, the difference is also reported as a change in the transaction price. We require prepayment from certain customers. We record any payments received in advance of contract fulfillment as a contract liability and they are classified as customer deposits on the consolidated balance sheet.

Earnings Per Share, Policy [Policy Text Block]	Net Loss per Common Share We compute net loss per common share using the weighted average number of common shares outstanding during the period, and diluted net loss per common share using the additional dilutive effect of all dilutive securities. The dilutive impact of unvested restricted shares accounts for the additional weighted average shares of common stock outstanding for our diluted net loss per common share computation. We calculated basic and diluted net loss per common share as follows (in thousands, except per share data): Three Months Ended September 30, 2024 2023 Numerator Net loss $ (1,982 ) $ (695 ) Denominator Basic weighted average common shares outstanding 5,919 5,850 Dilutive effect of restricted stock — — Diluted weighted average common shares outstanding 5,919 5,850 Basic net loss per common share $ (0.33 ) $ (0.12 ) Diluted net loss per common share $ (0.33 ) $ (0.12 ) We exclude the impact of restricted stock from the calculation of diluted net loss per common share in periods where we have a net loss or when their inclusion would be antidilutive.

Based on historical payment trends, we expect that these customers will take advantage of these early payment discounts. The cost of these discounts is reported as a reduction to the transaction price. If the actual discounts differ from those estimated, the difference is also reported as a change in the transaction price. We require prepayment from certain customers. We record any payments received in advance of contract fulfillment as a contract liability and they are classified as customer deposits on the consolidated balance sheet.
