(1)Account Receivables/Contract Assets: additions charged to expense represent bad debt provisions relate to estimated losses due to credit and similar collectability issues.

(2)Account Receivables: Other charges (credits) relate to adjustments to reserves necessary to reflect events of non-payment such as customer accommodations and contract terminations.

(3)Account Receivables/Contract Assets: Deductions and other, net of recoveries primarily relates to receivable and contract asset write-offs, but also includes reclassification to other balance sheet accounts, the impact of foreign currency translation adjustments and recoveries of previously written off receivables and contract assets.

(4)Tax Valuation: tax valuation allowance are primarily related to certain net operating loss carryforwards, tax credit carryforwards and deductible temporary differences for which we have concluded it is more-likely-than-not that these items will not be realized in the ordinary course of operations.
