Equity Method Investments and Joint Ventures [Abstract]
Investment	Investment As discussed in Note 13 “Deconsolidation”, on September 16, 2015, we deconsolidated Kingstone, reducing our ownership to 15% of the Hong Kong holding company. Our investment in Kingstone is accounted for using the equity method for periods subsequent to the deconsolidation due to our ability to exert significant influence over the financial and operating policies of Kingstone, primarily through our representation on the board of directors. We recognize our portion of net income or losses on a one-quarter lag. The resulting equity method investment was initially recorded at fair value at $2.7 million using the value the third party purchaser placed on their investment in Kingstone Shanghai, a Level 2 input in the fair value hierarchy. The carrying value of the equity method investment in Kingstone was $2.6 million and $3.0 million as of September 30, 2017 and 2016, respectively. As of September 30, 2016, our carrying value of Kingstone exceeded its share of the underlying equity in the net assets by approximately $2.7 million. In accordance with ASC Topic 323, Investments - Equity Method, the difference (the “basis difference”) between the initial fair value of our investment and the proportional interest in the underlying net assets of Kingstone was accounted for using the acquisition method of accounting, which requires that the basis difference be allocated to the identifiable assets and liabilities of Kingstone at fair value and based upon our proportionate ownership. Determining the fair value of assets and liabilities is judgmental in nature and involves the use of significant estimates and assumptions. During the fourth quarter of 2016, we completed our valuation of the identifiable assets to which the basis is attributable and recorded amortization based on this valuation for the year ended September 30, 2016.

As discussed in Note 13 “Deconsolidation”, on September 16, 2015, we deconsolidated Kingstone, reducing our ownership to 15% of the Hong Kong holding company. Our investment in Kingstone is accounted for using the equity method for periods subsequent to the deconsolidation due to our ability to exert significant influence over the financial and operating policies of Kingstone, primarily through our representation on the board of directors. We recognize our portion of net income or losses on a one-quarter lag. The resulting equity method investment was initially recorded at fair value at $2.7 million using the value the third party purchaser placed on their investment in Kingstone Shanghai, a Level 2 input in the fair value hierarchy. The carrying value of the equity method investment in Kingstone was $2.6 million and $3.0 million as of September 30, 2017 and 2016, respectively.

As of September 30, 2016, our carrying value of Kingstone exceeded its share of the underlying equity in the net assets by approximately $2.7 million. In accordance with ASC Topic 323, Investments - Equity Method, the difference (the “basis difference”) between the initial fair value of our investment and the proportional interest in the underlying net assets of Kingstone was accounted for using the acquisition method of accounting, which requires that the basis difference be allocated to the identifiable assets and liabilities of Kingstone at fair value and based upon our proportionate ownership. Determining the fair value of assets and liabilities is judgmental in nature and involves the use of significant estimates and assumptions. During the fourth quarter of 2016, we completed our valuation of the identifiable assets to which the basis is attributable and recorded amortization based on this valuation for the year ended September 30, 2016.
