What are the major factors affecting sample size for confirming accounts receivable?

Answer:

The factors include:
• tolerable misstatement,
• inherent risk (e.g., relative size of accounts receivable and number of accounts),
• control risk,
• achieved detection risk form other substantive tests, and
• the type of confirmation (e.g., negative normally requires a larger sample size).
