Plus it had a $1,000,000 prize money pool, and all ISG events either had $1,000,000 or $800,000 prize money pools, so it offered more prize money than tournaments like Vienna.
So with exactly the same (or more) prize money and ranking points on offer we can safely say that it was a precursor to a 500 event before 2009 and wasn't a lesser tournament
. And the tournament always attracted strong field with some of the best indoor players on the tour like Nalbandian and Henman playing their regularly, Roddick playing there during his peak in 2003 etc.
Once again. It was NOT a gold. It was a world series and it gave 250 points to the winner (at least the 3 years when Fed won it). It became a 500 (and so gave 500 points to the winner) in 2009. Check the ATP site if you won't take my word for it. (The precursors of the 500 were the "gold" or "CS" and Basel wasn't one. The precursor was Vienna. In 2009, they simply downgraded Vienna and made Basel a 500 instead).
