Marketable Securities Disclosure [Text Block]

3.	Marketable Securities:
	The Company categorizes marketable securities as either trading, available-for-sale or held-to-maturity. Trading securities are carried at fair value with unrealized gains and losses included in income. Available-for-sale securities are carried at fair value measurements using quoted prices in active markets for identical assets or liabilities with unrealized gains and losses recorded as a separate component of shareholders' equity. Held-to-maturity securities are carried at amortized cost. Dividends and interest income are accrued as earned. Realized gains and losses are determined on a specific identification basis. The Company reviews marketable securities for impairment whenever circumstances and situations change such that there is an indication that the carrying amounts may not be recovered. The Company did not classify any securities as trading during the nine months ended April 30, 2013 and April 30, 2012. The Company also did not classify any securities as trading at July 31, 2012.
	The Company adopted Accounting Standards Certification (ASC) 820, Fair Value Measurements and Disclosures in 2011. ASC 820 establishes a fair value hierarchy that prioritizes the valuation techniques and creates the following three broad levels, with Level 1 valuation being the highest priority:

Level 1 valuation inputs are quoted market prices in active markets for identical assets or liabilities that are accessible at the measurement date (e.g., equity securities traded on the New York Stock Exchange).

Level 2 valuation inputs are from other than quoted market prices included in Level 1 that are observable for the asset or liability, either directly or indirectly (e.g., quoted market prices of similar assets or liabilities in active markets, or quoted market prices for identical or similar assets or liabilities in markets that are not active).

Level 3 valuation inputs are unobservable (e.g., an entity’s own data) and should be used to measure fair value to the extent that observable inputs are not available.

In accordance with the provisions of Fair Value Measurements, the following are the Company's financial assets presented at fair value at April 30, 2013 and July 31, 2012.
