I have combined these two interests together to create "fiqua", a fledgling company account analyser. Currently, it performs only one calculation: the Altman z-score for non-manufacturers. I plan to add more functionality. The calculator can be downloaded here. The program is free, and contains no spy- or ad- ware. Simply download the file, unzip it, and click on the executable file. Let me know if you have any problems.
The first company I tried it on was TCG.L (Thomas Cook), which is on my watch list - deathwatch list, that is. It looks pretty poorly to the naked eye, but the z-score confirms the bad news. My program calculates it as -1.2, well into the danger zone. Here are the specific numbers I pulled from Digital Look:
Total Assets: 6900
Total Liabilities: 5157
Working Capital: -1922 (Current Assets 1463 - Current Liabilities 3385)
Retained Earnings: -626
Mkt Cap: 624
