Outstanding purchase orders with Ablecom were $53,684,000 and $63,151,000 at June 30, 2013 and 2012, respectively, representing the maximum exposure to loss relating to (a) above.

("Management Company") in Taiwan to manage the common areas shared by the Company and Ablecom for their separately constructed manufacturing facilities. Each company contributed $168,000 and own 50% of the Management Company. Although the operations of the Management Company are independent of the Company, through governance rights, the Company has the ability to direct the Management Company's business strategies. Therefore, the Company has concluded that the Management Company is a variable interest entity of the Company as the Company is the primary beneficiary of the Management Company. The accounts of the Management Company are consolidated with the accounts of the Company, and a noncontrolling interest has been recorded for the Ablecom's interests in the net assets and operations of the Management Company. The Management Company had no business operations as of June 30, 2012. In fiscal year 2013, $13,000 of net income attributable to Ablecom's interest was included in the Company's general and administrative expenses in the consolidated statements of operations.
