The accompanying unaudited financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America for interim financial information and with the instructions to Form 10-Q and Regulation S-X. Accordingly, these condensed financial statements do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation have been included and such adjustments are of a normal recurring nature. These financial statements should be read in conjunction with the financial statements for the year ended July 31, 2015 and notes thereto and other pertinent information contained in the Form 10-K the Company has filed with the Securities and Exchange Commission (the “SEC”).
