The information that that particular drug was not zero-rated actually came to us from CRA. The question as to why that one is not zero-rated is because there is another very similar drug that is called isosorbide dinitrate, and that one was on the list. Basically, there was no logic to have the dinitrate and not the isosorbide-5-mononitrate on the list, because they are both used to treat congestive heart failure.
