1998? 2000 (or at least 1999) should be available...... They are due in May if I remember correctly, though they could've received and extension. Haven't had to complete one in several years, thankfully... :-)
They typically ask for two extensions every year and finally deliver the goods by November.
Remember, this is online. There is a web site which takes the microfiche or whatever and puts it in pdf's. I expect a year lag at least.
