Display Ledger Balances in AX 2009

Hi Techies,

I have one question regarding the display of Ledger Balances in the below path in AX 2009

General Ledger > Common Form > Chart of Accounts > Balances > Setup

When I am seleting the 'Fiscal Year', then system is showing different balance for the GL's

But when I am putting the same date '3/31/2015' in the 'To Date' field, system is showing different balances for the same GL accounts.

Could you please let me know what is the difference between these two selection procedure of 'Fiscal Year' and 'From Date - To Date' ?

I will be waiting for your valuable feedback.

Thanks.
