The statement is True. According to the textbook context, Cash Flow Statement is indeed a tool of financial statement analysis. The context explicitly mentions that 'Cash flow analysis' is one of the techniques of financial analysis, along with comparative statements, common size statements, trend analysis, and ratio analysis. The Cash Flow Statement analyses the actual movement of cash into and out of an organisation, showing sources of cash receipts and purposes for which payments are made. It summarises the causes for changes in cash position between two balance sheet dates. Furthermore, in the 'Test your Understanding – III' section of the textbook, this exact statement appears as a True/False question, confirming its validity as a correct statement about financial analysis tools.
