Receivables [Abstract]

Receivables

Receivables

Receivables consist primarily of amounts due from government agencies, which may be subject to potential retroactive adjustments. Because substantially all of our receivable amounts are readily determinable and substantially all of our creditors are governmental authorities, our allowance for doubtful accounts is insignificant. Any amounts determined to be uncollectible are charged to expense when such determination is made.
