Question about reconciliation step in Assets User Guide

In the User Guide for Assets, under Reconciling Depreciation Expense Accounts, there is this sentence: "Use the Journal Entry Reserve Ledger report to match the depreciation balances with the ending GL depreciation balances." Question: where should we look for "depreciation balances" and "ending GL depreciation balances" in order to do this reconciliation step? Can anyone flesh this guidance out a little? Thanks.
