Estimate of Bond Rating

The score for UNH based on the Altman model is a score of 3.23. Based on the bankruptcy range for this model, the bond rating for UNH is estimated in the 'safe zone'. UNH Z score demonstrates its financial strength, as the company reported revenues of \$94.1 million dollars, an increase of 8.05% over 2009 and an operating profit of \$7.9 million, an increase of 23.67% over 2009. UNH's Earnings before Interest and Taxes (EBIT) to total assets score is 0.4 and this gives a good indication of how effectively the company is converting the money it has invested into net income. The company could do a better job though at generating more net income from its total assets. UNH has a negative working capital and is likely to experience problems meeting its short-term obligations because the company does not have enough current assets to satisfy its short-term debts.
