I looked at the report in the OP. The numbers seem generally in-line with what I know, but terp06 is right in that they got the timing wrong. The 6 months immediately after graduation is considered the stub year. Fresh MBA grads join as associates and typically get some type of fixed bonus for that period, base salary of around $95k (annualized), and for the past couple of years the standard signing bonus of around $40k. Then, the new calendar year will mark the first full year for associates. Base salary will be unchanged (generally $95k) and bonuses are basically what is shown for second years in the chart ($210-240k). The bonus numbers in the second table are somewhat lower than typical levels at BB i-banks and probably include numbers from regional firms and/or other departments (like fixed income or research).
2006 was a very good year for I-bank compensation. 2007 was a better year, with most of the top banks setting all-time compensation records even as business dried up half-way through. 2008 will be a crappy year, I've read estimates in business publications that bonus levels will be down anywhere from 15-40% compared to last year. The people that keep their jobs will still get healthy paychecks; the real thing to watch for is how many people are let go. There's already been a lot of bloodletting, and the rumors are that huge announcements will be coming in the next month or so, as firms usher out their summer associates and take stock of how bad business has been. Regional firms, non-public firms, and firms that don't back transactions with their own balance sheet (advisory only firms) seem to be the safest, and in fact many of those are doing quite well. Firms with all sorts of stuff ranging from MBS's, CDO's, auction rate securities and other stuff on their balance sheets are taking a bath.
Senior Vice President and Director are exactly the same level; just different titles used at different firms for the same position.
ac8706, the transition is always associate to VP at the bigger firms. Some of the smaller firms might have their own quirks, and of course PE firms are so small they all operate differently. With the crappy economy, everyone is starting at the 1st year associate level. When banking is booming and recruiting is hot and heavy, I have heard of people with relevant related experience (for example in PE or as a lawyer) being credited for prior experience and brought in at more senior levels; that's definitely not going to happen for people graduating this year.
