In accordance with the Income Tax Topic of the ASC, a valuation allowance is recognized if, based on the weight of available evidence, it is more-likely-than-not that some, or all, of the deferred tax asset will not be realized. As a result of the risks and uncertainties associated with future operating results, management believes it is more likely than not that the Company will not generate sufficient taxable income to recover the deferred tax operating asset and therefore has a full valuation allowance.

NOL Usage Table



NOL Usage Tier	Allocated NOLs			Applicable Percentage
A	The first	$479,000		15%
B	The next	$1,057,000	after Tier A	40%
C	The next	$1,057,000	after Tier B	10%
D	The next	$1,057,000	after Tier C	15%

Any post determination date NOLs generated by Ambac Assurance are utilized prior to any Allocated NOLs for which Tolling Payments will be due. Ambac Assurance has utilized all of its current post determination date NOLs generated from September 30, 2011 through December 31, 2016 , generating cumulative taxable income of $1,086,124. Of the bankruptcy related credits available to offset the first $5,000 of payments due under each of the NOL usage Tiers A, B, and C, Ambac Assurance has fully utilized the combined $10,000 of Tier A and Tier B credits. For the two years ended December 31, 2016, Ambac Assurance utilized all of the $479,000 Tier A NOL and $607,124 of the $1,057,000 Tier B NOL resulting in cumulative Tolling Payments, net of applicable credits, of $100,145, of which $71,454 was paid to Ambac in 2016 and $28,691 which is to be paid no later than June 2, 2017. For the three months ended March 31, 2017, Ambac Assurance generated a new post determination date NOL of $32,084, which must be utilized before further tolling payments are accrued.

Beginning on the fifth anniversary date subsequent to Ambac's May 1, 2013 emergence from bankruptcy, and subject to Ambac's consent, not to be unreasonably withheld, to the extent Ambac Assurance generates post-determination date income in excess of the $3,650,000 Allocated NOLs, Ambac Assurance may utilize Ambac's then remaining NOLs in exchange for a payment of 25% of the federal income tax liability that Ambac Assurance would have paid had Ambac's NOLs not been available. After Ambac fully utilizes its Allocated NOLs it may utilize Ambac Assurance's then remaining Allocated NOLs in exchange for a payment of 50% of the federal income tax liability that Ambac would have paid had Ambac Assurance's NOL not been available.

As of March 31, 2017, the remaining balance of the $3,985,606 NOL allocated to Ambac Assurance was $2,595,960. As of March 31, 2017 Ambac's NOL was $1,389,646.
