These joint ventures procure inventory on behalf of the Company and the other joint venture partners. The variable interests relate to equity investments and advances made by the Company to the joint ventures. In addition, the Company also guarantees one of its joint venture’s borrowings which also represents a variable interest in that joint venture. The Company is not the primary beneficiary, as it does not have the power to direct the activities that most significantly impact the economic performance of the entities as a result of the entities’ management and board of directors structure. Therefore, these entities are not consolidated. At June 30, 2013 and 2012, and March 31, 2013, the Company’s investment in these joint ventures was $22,944, $23,150, and $23,986, respectively and is classified as Investments in Unconsolidated Affiliates in the Condensed Consolidated Balance Sheets. The Company’s advances to these joint ventures were $296 and $9 at June 30, 2013 and 2012, respectively and are classified as Accounts Receivable, Related Parties in the Condensed Consolidated Balance Sheets. There were no advances at March 31, 2013. The Company guaranteed an amount to a joint venture not to exceed $18,764, $19,164 and $19,363 at June 30, 2013 and 2012, and March 31, 2013, respectively. The investments, advances and guarantee in these joint ventures represent the Company’s maximum exposure to loss.</div></div>falsefalsefalsenonnum:textBlockItemTypenaVariable Interest Entity [Text Block]No definition available.false0Variable Interest EntitiesfalseVariable Interest EntitiesUnKnownUnKnownUnKnownUnKnowntruefalsefalseSheethttp://www.aointl.com/role/VariableInterestEntities12
