Your discussion should include the firm specific and economy wide factors that might influence the percentage of fixed rate debt.

No calculations required.(ii) Does the firm have borrowings?(iii) What is the relative size of these borrowings or other measures of the extent of the firm’s financial obligations? Does the firm disclose its leverage ratios? If not try to calculate them. How do they compare with the industry average?(iv) Is the firm able to generate cash/profits so that it can pay its financial obligations? Does the firm disclose its interest coverage ratios? If not try to calculate them. How do they compare with the industry average?(v) Is the interest payment on the borrowings a fixed or floating rate?(vi) What is the percentage of fixed or floating rate debt before the effect of hedging? If possible provide this data from 2015 to 2020.(vii) What are the trends in various financial obligations ratios?(Leverage, interest coverage ratios etc)(d) Using data and information contained in your firms annual reports describe and explain the interest rate hedging strategy employed by the firms.

If you cannot determine then indicate this.(v) Explain why the particular hedging strategy might have been adopted.(vi) What is the percentage of fixed or floating rate debt after the effect of interest rate hedging instruments?
