Let's see if we can clear up the convolution on what the listing meant. It's not as scary as it looks.
Here's the first paragraph of the listing:
They actual summarize it quite nicely. The purpose of the filing was "indicating a decrease". You could calculate that by following along with the arithmetic: - Previous holding: 250,000 - Current holding: 235,461 If you look at those numbers, the current holding is less than the previous holdings, so it's a decrease. To get more fancy you could actually perform the calculation yourself on a calculator - just enter the Previous Holding number first (250,000), then the "-" sign, then the Current Holdings number (235,461). And that will give you how many shares they decreased their holdings. If I had more time I would explain how to calculate the percentage - maybe look that up on Google.
