Accounts Receivable [Abstract]

ACCOUNTS RECEIVABLE

NOTE 5 — ACCOUNTS RECEIVABLE

Amounts retained by project owners under construction contracts and included in accounts receivable at October 31, 2011 and January 31, 2011 were approximately $6.1 million and $3.9 million, respectively. The lengths of retention periods may vary, but for material amounts they typically range between nine months and two years.

The allowance for doubtful accounts at both October 31, 2011 and January 31, 2011 was approximately $5.5 million. In fiscal year 2010, a substantial portion of the accounts receivable from the owner of a partially completed construction project was written down against the allowance, without any effect on income, to $5.5 million, the amount of the net proceeds remaining from a public auction of the facility. As the amount that the Company may ultimately receive in a distribution of the auction proceeds, if any, is not known at this time, the remaining account receivable amount was fully reserved. The amounts of the provision for accounts receivable losses for the three and nine months ended October 31, 2011 and 2010 were not material.
