The Company's typical credit terms are Net 30, however, it does offer terms up to 180 days on floor plan units.

The Company performs additional analysis on amounts over 90 days monthly to determine collectability. The Company has assigned expected credit loss percentages based on where the asset falls in the aging schedule. The Company's actual credit losses have been low compared to historical allowance estimates. The Company had to consider the current interest rate environment and the recent decline in the agricultural commodity market and believes its method of estimating a higher than historical loss percentage to be an adequate estimate. The Company foresees increased credit risk over the next year or so until inventory on dealer lots starts to decline, interest rates drop and farm income strengthens. The Company carries contract assets related to its Modular Buildings segment in the form of costs and profit in excess of billings. These contract assets are typically converted to trade receivables in 30 to 90 days, depending on contract terms, and due 30 days or less from the billing date. Because these contract assets are typically converted to receivables and collected in less than a year, consideration for these contract assets have been included in the expected credit loss model for trade receivables.

The Company uses aging categories to estimate expected credit losses on trade receivables. The Company considers in its analysis: historical loss experience, forward-looking macroeconomic factors, company credit risk including previous delinquencies, disputed amounts, and the intent and ability to pay. The Company's typical credit terms are Net 30, however, it does offer terms up to 180 days on floor plan units. The Company would consider trade receivables greater than 30 days past due, but is not required to disclose past due receivables with an original term less than one year. The Company performs additional analysis on amounts over 90 days monthly to determine collectability. The Company has assigned expected credit loss percentages based on where the asset falls in the aging schedule.
