Using the consolidated financial statements of a selected company, could you conduct a critical analysis of the company's financial performance, comparing the results to the prior year and industry averages provided in Appendix 1? The analysis should highlight the company's strengths, areas of concern, and suggestions for improvement. Please ensure the computation of all profitability, liquidity, financial gearing, and investment ratios is included, with clear calculations and formulas noted. These calculations should be attached as an appendix to the report and not included in the main body of the text. In the main body of the report, undertake a critical analysis of any five ratios, focusing on at least one ratio from each of the four categories of ratios. Additionally, include a summary table showing the five ratios selected for discussion in the main body of the report.
