The purpose of research is to investigate the accrual principles in Accounting that contained in the Company's Financial Statements. The accrual principle is reflected in the Balance Sheet and Income Statement. Accrual measurements in the Balance Sheet are measured using PersistenceCurrent Operating Accrual, Persistence Non-Current Operating Accrual. Idiosyncratic risk reflects the specific information about the company and it will fluctuate according to the information itself. To measure the idiosyncratic risk in this study five factors of Fama-French Model were used (Fama and French 2014). Asset Pricing Measurement uses the Dividend Disscounted Model to predict stock prices. The samples used in this study are listed below. The Manufacturing Company is selected with consideration for accrual measurement of accounts receivable, inventory, investment and liabilities. The sample was chosen by purposive random sampling method. The number of samples generated by this method is 145 companies with full reports for 2010-2015. Using the SEM AMOS Ver.24 and Sobel Test Path Analysis, the results show that Current Operating Accrual has a negative and significant relationship to the idiosyncratic risk and stock price. For non-Current Operating Accrual variables have positive and significant relation. By using Sobel Test, the test result shows that idiosyncratic risk has mediation effect in Persistence Current Operating Accrual, Non-Current Operating Accrual relationship to stock price.
