Litigation and Claims

The Municipal Revenue Collection Center of Puerto Rico (“CRIM”) conducted a personal property tax audit for the years 1999 and 2000 which resulted in assessments of approximately $320,000 (approximately $559,807 as of February 14, 2014, including interest and penalties). The assessments arose from CRIM’s disallowances of certain credits for overpayments from 1999 and 2000, claimed in the 2001 through 2003 personal property tax returns. During the audit process, CRIM alleged that some components of the inventory reported as exempt should be taxable. The parties met several times and an informal administrative hearing was held on September 27, 2006. CSPR submitted its position in writing within the time period provided by CRIM. CSPR believed it had strong arguments to support its position that the components of inventory qualify as raw material and that a settlement could be reached for an amount less than the assessment. Accordingly, the Company had previously recorded a liability, which had a balance of $96,000 as of July 31, 2013. On February 12, 2014 CSPR received a payment demand notice from the CRIM in the amount of $559,807, but provided that if CSPR entered into a settlement agreement on or prior to March 27, 2014, CSPR could settle the outstanding amount for $320,000 and take advantage of an amnesty provision which would eliminate accumulated interest and penalties. Management has entered into a settlement agreement to settle this claim for the initial assessment of approximately $320,000 and has recorded an additional liability of $224,000 as of April 30, 2014 in anticipation of this settlement. The settlement amount is due in twelve equal installments, beginning May 1, 2014, and bears no interest.

The Company is involved in various matters of litigation, claims, and assessments arising in the ordinary course of business. In the opinion of management, the eventual disposition of these matters will not have a material adverse effect on the financial statements.
