This report provides a detailed analysis of accounting and finance principles through the examination of three companies: Terry Joe Plc, Kokolet Limited, and Smith Howe Limited. It begins with the preparation of financial statements, including a profit and loss statement and balance sheet for Terry Joe Plc. The report then delves into break-even analysis for Kokolet Limited, calculating contribution per unit, break-even point, and margin of safety. Furthermore, the study assesses investment appraisal techniques, such as payback period, accounting rate of return (ARR), and net present value (NPV) to aid Smith Howe Ltd in investment decisions. Finally, the report explores the benefits and limitations of budgeting for strategic planning, including a discussion of the assumptions underpinning break-even analysis and the impact of budget implementation on organizational ambition and creativity.
