Operator
(Operator instructions) We will go first to Russ Silvestri and SKIRITAI Capital.
Russ Silverstri -- SKIRITAI Capital
Hi, congratulations. Actually I have four questions. One is Vyvanse being second sourced by anyone?
Mark Frost
Yes, this is Mark Frost, we are the primary company on the sourcing of Vyvanse, but there is a secondary supply contract.
Russ Silverstri -- SKIRITAI Capital
Is that the reason for the -- I perceive to be a slowdown from there.
Mark Frost
Actually, we do not believe that is the reason. The issue as we discussed on our last conference call is that what has come out with Shire is that more inventory was built last year than was needed. And they have come in at the lower end of their expectations for the launch of Vyvanse which put us in a situation, where we expect likely suffice to restart Q1 next year, there is an outside chance Q4, there could be supplies but we have not built that in to any of our guidance.
Russ Silverstri -- SKIRITAI Capital
And then also I think in the past you've given us a total number of customers that you have. I was wondering if you could give me the totals and maybe just the quarterly growth in new customers --
Mark Frost
Sure. I look at it. On a year-to-date basis, we're roughly handling about 200 customers, close to 600 projects and that is increased roughly about 15% to 20% on the prior quarter.
Russ Silverstri -- SKIRITAI Capital
I guess all those customers are in the developmental and small scale.
Mark Frost
Small scale tends to be the larger portion of our customers, yes, and projects.

And then when you look at the Hungarian business, I didn't know you may have broken it out in the press release, but I haven't got to it in detail yet, but what were the costs associated with that reconfiguration and then with that, is there any endemic situation that causes that to not be as successful as India. Obviously, India and Singapore, you made nice investments there and they worked. The Hungarian seemed like it started okay and then it's not met your expectations or I guess -- anyone's expectations. Is there a problem there? Is there something that the Europeans won't do that they are doing somewhere else?
