RE:RE:RE:RE:Jason Donville Moves the StockPSD has a rather unusual accounting. They are allowed to depreciate the newly acquired data at a fast clip. This creates a large non-cash depreciation expense. This non-cash expense supresses earnings. In fact, they often report negative earnings because of it (which also means they don't have to pay tax on the library sales).
The bottom line, PSD doesn't screen well at all. You need to take time to understand the business model and accounting.
