A main purpose of our project is to examine the financial condition of 3 chosen companies: a financial institution, a non-profit organizations, as well as the production company. All companies are existing at the Polish market. To make the calculations and tests we used the method of John Zietlowacontained in the publication: "A Financial Health Index for Achieving Financial Sustainbility." To receive the PHI index is necessary to calculate the several component indicators, which also provide us with the information needed to analyze the company on several different levels. The calculations shown in our paper are made on the basis of the companies' financial statements for the years 2009, 2010 and 2011
