[4] | Represents additional allowance for doubtful accounts of approximately $2,213,000 recorded as a result of uncollected receivables from three major customers, reversal of $45,000 in uncollectible accounts receivables and reversal of unbilled receivables related to conditions that existed at the time of our acquisition.
[5] | Represents tax true-up and write-off of bid deposit that existed as of the acquisition date.
[6] | Represents book to tax timing differences resulting from allowance for doubtful accounts and change in fair value of contracts as noted in footnote (3) and (5).
[7] | Reflects additional goodwill recorded since initial acquisition date in finalizing the final purchase price allocation related to acquired assets and liabilities under this business combination.

The termination of the October Note resulted from settlement of certain claims made by the Company against TNC primarily from the breach of representation regarding the cost to complete a certain contract that existed at acquisition. A New Note in the amount of $230,000 was issued to TNC in placement of the October Note that was cancelled (see above for further discussions of the October and New Notes).
