The company's strengths can be seen in multiple areas, such as its solid stock price performance, impressive record of earnings per share growth and compelling growth in net income. However, as a counter to these strengths, we find that the company has not been very careful in the management of its balance sheet. You can view the full UDR Ratings Report.
