Complete the following for the communications company "CenturyLink" in an Excel spreadsheet:
1. Horizontal and vertical analysis of the Income Statements for the past three years (all yearly balances set as a percentage of total revenues for that year).
2. Horizontal and vertical analysis of the Balance Sheets for the past three years (all yearly balances set as a percentage of total assets for that year).
3. Ratio analysis (eight ratios of your choosing) for the past three years PLUS a measurement for the creditworthiness of your firm as measured by Altman's Z-score. Note that if you used your chosen firm for our ratio-related discussion posts, then you MUST also present industry-average ratios or current year competitor ratios for your ratio analysis. Comparing your firm's ratios to a close competitor or an industry-average ratio makes your analysis much more meaningful.
