Fair Value, Measurement Inputs, Disclosure [Text Block] | 18. FAIR VALUE MEASUREMENTS The Company follows the authoritative guidance on fair value measurements and disclosures with respect to assets and liabilities that are measured at fair value on both a recurring and non-recurring basis. Under this guidance, fair value is defined as the exit price, or the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. The authoritative guidance also establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs market participants would use in valuing the asset or liability, developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the factors market participants would use in valuing the asset or liability developed based upon the best information available in the circumstances. The categorization of financial assets and financial liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The hierarchy is broken down into three levels defined as follows:
| Level 1 - | Inputs are quoted prices in active markets for identical assets or liabilities.
| Level 2 - | Inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs (other than quoted prices) that are observable for the asset or liability, either directly or indirectly.
| Level 3 - | Inputs are unobservable for the asset or liability.
See the section below titled Valuation Techniques for further discussion of how the Company determines fair value for investments. Assets and Liabilities That Are Measured at Fair Value on a Recurring Basis Assets and liabilities that are measured at fair value on a recurring basis primarily relate to marketable equity securities. These items are marked-to-market at each reporting period. The following tables provide information by level for assets and liabilities that are measured at fair value on a recurring basis:
|  |  |  |  | Fair Value Measurements Using Inputs Considered as |
|  | Fair value as of August 31, 2013 |  |  | Level 1 |  |  | Level 2 |  |  | Level 3 |
Cash equivalents |  | $ | 1,020,000 |  |  | $ | 1,020,000 |  |  | $ | — |  |  | $ | — |
|  |  |  |  | Fair Value Measurements Using Inputs Considered as |
|  | Fair value as of August 31, 2012 |  |  | Level 1 |  |  | Level 2 |  |  | Level 3 |
Cash equivalents |  | $ | 1,518,000 |  |  | $ | 1,518,000 |  |  | $ | — |  |  | $ | — |
Valuation Techniques Financial assets that are classified as Level 1 securities include Cash equivalents. These are valued using quoted market prices in an active market. The Company reviews the fair value hierarchy classification on a quarterly basis. Changes in the ability to observe valuation inputs may result in a reclassification of levels for certain securities within the fair value hierarchy. The Company’s policy is to recognize transfers into and out of levels within the fair value hierarchy at the end of the fiscal quarter in which the actual event or change in circumstances that caused the transfer occurs. There were no transfers between Level 1, Level 2, or Level 3 during the fiscal years ended August 31, 2013 or August 31, 2012. When a determination is made to classify an asset or liability within Level 3, the determination is based upon the significance of the unobservable inputs to the overall fair value measurement. Assets and Liabilities That Are Measured at Fair Value on a Nonrecurring Basis The following tables provide information by level for assets and liabilities that are measured at fair value on a Nonrecurring basis:
|  |  |  |  | Fair Value Measurements Using Inputs Considered as |
|  | Fair value as of August 31, 2013 |  |  | Level 1 |  |  | Level 2 |  |  | Level 3 |
Fair market value of NTI Asean |  | $ | 7,922,000 |  |  | $ | — |  |  | $ | — |  |  | $ | 7,922,000 |
The Company determined the fair value of NTI Asean using the capitalized income method, including a capitalization rate of 25%.
