Query runs very slowly againts views

Question

Hi,
I have the below query to update the final report table which will be used creating a report file.
select [Collateral ID], [DataDate],
[Cif], [Collateral Category],
[Expiry Date], [Realizable Amount], [Currency],
[Classification of Property], [Market Value],
[Country],[CB_Guarantor], [CB_Guarantee]
from v0_AccountSecuritiesBASEL_III
WHERE
((DataDate)='2014-04-30')
and [Collateral ID] NOT IN (Select [Collateral ID] from [dbo].[v1_AccountSecuritiesBASEL_III])
If I run it with only the date restrict

Answer 1

And  is it running slow? What indexes do the tables have?
What if you re-write the WHERE condition in that way?
WHERE
((DataDate)='2014-04-30')AND NOT EXISTS (Select * from [dbo].[v1_AccountSecuritiesBASEL_III] V WHERE V.[Collateral ID]=v0_AccountSecuritiesBASEL_III.Collateral )
