A. How much interest-bearing short-term debt did AT&T have at the end of 2020 and what was the average cost of this debt? (Hint: Access AT&T's 2021 annual report at http://att.sbc.com/gen/landing-pages?pid=3309 , and look at "Note 12. Debt Obligations", found in the Notes to the consolidated financial statements). http://www.att.com/gen/investor-relations?pid=9186

B. What was AT&T's actual capital structure at the end of 2020, based on its consolidated balance sheets? What portion of AT&T's capital structure did short-term debt, long-term debt, and stockholders' equity represent in 2020? Short-term debt will be defined as the total debt maturing within one-year, and long-term debt will be the figure given the Consolidated Balance Sheet.

C. Now recalculate AT&T's capital structure just using long-term capital, i.e. long-term debt and common equity. Use your results from the previous question to accomplish this. Calculate the long-term debt to total long-term capital ratio and the common equity to total capital ratio
