Accounting Standards Update (&ldquo;ASU&rdquo;) No. 2014-09, &ldquo;Revenue from Contracts with Customers (Topic 606)&rdquo; (&ldquo;ASC
606&rdquo;). ASC 606 supersedes the revenue recognition requirements in &ldquo;Revenue Recognition (Topic 605)&rdquo; (&ldquo;ASC
605&rdquo;) and requires entities to recognize revenue when control of the promised goods or services is transferred to customers
at an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.
The Company adopted ASC 606 as of January 1, 2018.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">In
accordance with ASC 606, the Company applied the modified retrospective method to those contracts which were not completed
as of January 1, 2018. Under the modified retrospective method, the cumulative effect of applying the standard is recognized
at the date of initial application. Results for reporting periods beginning after January 1, 2018 are presented under ASC
606, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under
ASC 605. In implementing ASC 606, the Company was required to recalculate the revenue earned on any work in process at the
implementation date and to restate the revenue and cost of revenues as if Topic 606 had been followed from the inception of
the contract.&nbsp;&nbsp;In recalculating costs and revenue under Topic 606 guidelines, no material difference in the account
balances were identified. Since a material difference was not found, no retrospective analysis of account balance changes was
required. See &ldquo;Revenue recognition&rdquo; within the Summary of Significant Accounting Policies for further discussion regarding
revenue from contracts with customers.</FONT></P>

February 2016, the FASB issued ASU No. 2016-02, <I>Leases (Topic 842)</I>. The update&rsquo;s principal objective is
to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the
balance sheet. ASU 2016-02 continues to retain a distinction between finance and operating leases but requires lessees to
recognize a right-of-use asset representing its right to use the underlying asset for the lease term and a corresponding
lease liability on the balance sheet for all leases with terms greater than twelve months. The update is effective for fiscal
years beginning after December 15, 2018. Early adoption is permitted for financial statements that have not been previously
issued. The Company is currently evaluating the effects of ASU 2016-02 on the consolidated financial statements.&nbsp;Based
on the current evaluation the Company does not expect that ASU No. 2016-02, <I>Leases (Topic 842) </I>will have a material

transfer of risk and rewards, and also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenues
and cash flows from contracts with customers. Major provisions include determining which goods and services are distinct and represent
separate performance obligations, how variable consideration (which may include change orders and claims) is recognized, whether
revenue should be recognized at a point in time or over time and ensuring the time value of money is considered in the transaction
price.</FONT></P>

adoption of ASC 606 represents a change in accounting principle that aligns revenue recognition with the timing of when promised

obligations are satisfied</I></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><I>&nbsp;</I></P>



<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">The new revenue recognition standard requires the Company to
determine, at contract inception, whether it will transfer control of a promised good or service over time or at a point in time&mdash;regardless
of the length of contract or other factors. The Company now applies recognition of revenue over time, which is similar to the method
the Company applied under existing guidance (i.e. percentage of completion).</P>





<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">Due to uncertainties inherent in the estimation process, it
is possible that estimates of costs to complete a performance obligation will be revised in the near-term. For those performance
obligations for which revenue is recognized using a cost-to-cost input method, changes in total estimated costs, and related progress
towards complete satisfaction of the performance obligation, are recognized on a cumulative catch-up basis in the period in which
the revisions to the estimates are made. When the current estimate of total costs for a performance obligation indicate a loss,
a provision for the entire estimated loss on the unsatisfied performance obligation is made in the period in which the loss becomes
evident. For the three months ended March&nbsp;31, 2018 and 2017, there were no changes in total estimated costs that had a significant
impact to our operating results. In addition, for the three months ended March&nbsp;31, 2018 and 2017, there were no significant
losses recognized.</P>

revenues recognized under the cost-to-cost measure of progress. Contract liabilities additionally include advanced payments
from our customers on certain contracts. Contract liabilities decrease as the Company recognizes revenue from the
satisfaction of the related performance obligation and are recorded as either current or long-term, depending upon when
the Company is expected to recognize such revenue. The long-term portion of contract liabilities is included in
&ldquo;billing in excess of costs and estimated earnings on uncompleted contracts&rdquo; in the condensed consolidated

methods for recognizing revenue were very similar to the current method under ASC 606.&nbsp;&nbsp;The actual cost as a percent
of total expected cost at completion was used to estimate the percentage complete on fixed price jobs. Furthermore, the process
for allocating transaction price to performance obligations is also substantially similar to prior years. As a result, no material

Management provides an allowance for doubtful accounts based on the Company&rsquo;s historical losses, specific customer circumstances,

excess of reorganization value over fair-value of identified net assets upon emergence from bankruptcy on June 30, 2016. In accordance
with the accounting guidance on goodwill, the Company performs its impairment test of goodwill at the reporting unit level each
fiscal year, or more frequently if events or circumstances change that would more likely than not reduce the fair value of its
reporting unit below its carrying values. The Company first assesses qualitative factors to determine whether it is more likely
than not that the fair value of the reporting unit is less than its carrying amount, including goodwill. If management concludes
that it is more likely than not that the fair value of the reporting unit is less than its carrying amount, management conducts
a two-step quantitative goodwill impairment test. The first step of the impairment test involves comparing the fair value of the
applicable reporting unit with its carrying value. If the carrying amount of the reporting unit exceeds the reporting unit&rsquo;s
fair value, management performs the second step of the goodwill impairment test. The second step of the goodwill impairment test
involves comparing the implied fair value of the affected reporting unit&rsquo;s goodwill with the carrying value of that goodwill.
The amount by which the carrying value of the goodwill exceeds its implied fair value, if any, is recognized as an impairment loss.
The Company&rsquo;s evaluation of goodwill completed during the year ended December 31, 2017 resulted in no impairment losses.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">The
calculation of the Black-Scholes model involved the use of the fair value of the Company&rsquo;s common stock, estimated term,
volatility, risk-free interest rates and dividend yield (if applicable). The Company developed the assumptions that were used
as follows: the fair value of the Company&rsquo;s common stock was obtained from the terms of the recapitalization of the Company
including the Exit Facility, which occurred concurrent with the Company&rsquo;s emergence from bankruptcy protection, as well
as publicly traded market prices of the Company&rsquo;s common stock. The term represents the remaining contractual term of the
derivative; the volatility rate was developed based on analysis of the Company&rsquo;s historical stock price volatility and the
historical volatility rates of several other similarly situated companies (using a number of observations that was at least equal
to or exceeded the number of observations in the life of the derivative financial instrument at issue); the risk free interest
rates were obtained from publicly available United States Treasury yield curve rates; and the dividend yield is zero because the
Company has not paid dividends and does not expect to pay dividends in the foreseeable future.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><B><I>Share-based payments</I></B> &ndash; The Company measures
the cost of services received in exchange for an award of equity instruments based on the fair value of the award. For employees
and directors, the fair value of the award is measured on the grant date. The fair value amount is then recognized over the period
services are required to be provided in exchange for the award, usually the vesting period. The Company recognizes stock-based
compensation expense on a graded-vesting basis over the requisite service period for each separately vesting tranche of each award.
Stock-based compensation expense to employees is reported within payroll and related expenses in the consolidated statements of
operations. Stock-based compensation expense to non-employees is reported within marketing and business development expense in
the consolidated statements of operations. For the three-month period ended March 31, 2018, the Company did not have any stock-based
compensation expense to non-employees.</P>

taxes</I></B><I> &ndash; </I>The Company accounts for income taxes utilizing the asset and liability approach. Under this approach,
deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are
recovered or paid. The provision for income taxes generally represents income taxes paid or payable for the current year plus
the change in deferred taxes during the year. Deferred taxes result from the differences between the financial and tax bases of
the Company&rsquo;s assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">The
calculation of tax liabilities involves dealing with uncertainties in the application of complex tax regulations. The Company
recognizes liabilities for anticipated tax audit issues based on the Company&rsquo;s estimate of whether, and the extent to which,
additional taxes will be due. If payment of these amounts ultimately proves to be unnecessary, the reversal of the liabilities
would result in tax benefits being recognized in the period when the liabilities are no longer determined to be necessary. If
the estimate of tax liabilities proves to be less than the ultimate assessment, a further charge to expense would result.</FONT></P>

Company recognizes deferred tax liabilities and assets for the expected future tax consequences of events that have been included
in the consolidated financial statements or tax returns. Deferred tax liabilities and assets are determined based on the difference
between the financial statement basis and tax basis of assets and liabilities using enacted tax rates in effect for the year in
which the differences are expected to reverse. The Company estimates the degree to which tax assets and credit carryforwards will
result in a benefit based on expected profitability by tax jurisdiction. A valuation allowance for such tax assets and loss carryforwards
is provided when it is determined to be more likely than not that the benefit of such deferred tax asset will not be realized
in future periods. If it becomes more likely than not that a tax asset will be used, the related valuation allowance on such assets
would be reduced.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">The Tax Cuts and Jobs Act (the &ldquo;TCJA&rdquo;) was enacted
in the United States on December 22, 2017. The TCJA lowered the corporate tax rate from 35.0% to 21.0% and imposed a one-time transition
tax on unremitted earnings as of the end of 2017, and featured many other tax law provisions. The SEC issued Staff Accounting Bulletin
No. 118 &ldquo;<I>Income Tax Implications of the Tax Cuts and Jobs Act</I> (&ldquo;SAB 118&rdquo;)&rdquo; to address the U.S. GAAP
application of the TCJA. SAB 118 provides companies up to a year to finalize accounting for the impacts of the TCJA.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">In accordance with SAB 118, the Company recognized the income
tax effects of the TCJA in its consolidated financial statements for the year ended December 31, 2017. During the three months
ended March 31, 2018, the Company did not have any provisional tax expense for foreign withholding taxes associated with the TCJA.
The Company expects to finalize any provisional amounts associated with the TCJA over the next nine months based on ongoing assessment
of its tax positions and other relevant data.</P>

net income (loss) per share is computed by dividing the net income (loss) for the period by the weighted average number of common
shares outstanding during the period. Diluted net income (loss) per share is computed by dividing the net income (loss) for the
period by the weighted average number of common and potentially dilutive common shares outstanding during the period. Potentially
dilutive common shares consist of the common shares issuable upon the exercise of stock options and warrants. Potentially dilutive
common shares are excluded from the calculation if their effect is antidilutive. At March 31, 2018, there were options and warrants
to purchase 1,188,392 and 86,250 shares of common stock, respectively, outstanding that could potentially dilute future net income
(loss) per share. Because the Company had a net loss as of March 31, 2018, we are prohibited from including potential common shares
in the computation of diluted per share amounts. Accordingly, the Company has used the same number of shares outstanding to calculate
both the basic and diluted loss per share.</FONT></P>

square feet are considered as &ldquo;block sales&rdquo; and fourteen projects totaling approximately 685,056 square feet were
contracts combining all three phases or parts thereof and are considered as &ldquo;construction services&rdquo;. We expect that
all of this revenue will be realized by December 31, 2020.&nbsp;</P>

necessarily indicative of future backlog levels or the rate at which backlog will be recognized as revenue. The increase in backlog
of approximately $26.2 million from December 31, 2017 is primarily attributable to one large contract we entered into during the
first quarter for approximately $27.4 million.</P>

the ordinary course of business, SG Building enters into agreements with third parties that include indemnification provisions
which, in its judgment, are normal and customary for companies in its industry sector. These agreements are typically with consultants
and vendors. Pursuant to these agreements, SG Building generally agrees to indemnify, hold harmless and reimburse the other parties
for losses suffered or incurred by such parties with respect to actions taken or omitted by SG Building. The maximum potential
amount of future payments SG Building could be required to make under these indemnification provisions is unlimited. SG Building
has not incurred material costs to defend lawsuits or settle claims related to these indemnification provisions. As a result,
the estimated fair value of liabilities relating to these provisions is minimal. Accordingly, we have no liabilities recorded
for these provisions as of March 31, 2018.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">Our condensed consolidated financial statements have been prepared
using generally accepted accounting principles in the United States of America (&ldquo;GAAP&rdquo;), which require management to
make estimates and assumptions that affect reported amounts. The estimates and assumptions are based on historical experience and
on other factors that management believes to be reasonable. Actual results may differ from those estimates. Critical accounting
policies represent the areas where more significant judgments and estimates are used in the preparation of our condensed consolidated
financial statements. A discussion of such critical accounting policies, which include share-based payments, derivative instruments,
goodwill, intangible assets and revenue recognition, can be found in our 2017 Form 10-K. On January 1, 2018, the Company adopted
ASC Topic 606, &ldquo;Revenue from Contracts with Customers&rdquo; which has been referenced in Note 3 of the Notes to Condensed
Consolidated Financial Statements. There have been no other material changes in critical accounting policies from those disclosed
in the 2017 Form 10-K.</P>

reporting that occurred during the first quarter of 2018 that has materially affected, or is reasonably likely to materially affect,
our internal control over financial reporting. On January 1, 2018, the company adopted ASC Topic 606, &ldquo;Revenue from Contracts

revenue recognition.</P>

On November 4, 2011, the Company&amp;#8217;s wholly-owned subsidiary was merged with and into SG Building Blocks, Inc. (&amp;#8220;SG Building,&amp;#8221; formerly SG Blocks Inc.) (the &amp;#8220;Merger&amp;#8221;), with SG Building surviving the Merger and becoming a wholly-owned subsidiary of the Company. The Merger was a reverse merger that was accounted for as a recapitalization of SG Building as SG Building was the accounting acquirer. Accordingly, the historical financial statements presented are the financial statements of SG Building.&lt;/font&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px 0pt 0.5in; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;font style="font-family: 'times new roman', times, serif; font-size: 10pt;"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;font style="font-family: 'times new roman', times, serif; font-size: 10pt;"&gt;The Company provides two main products, both of which are used to meet the growing demand for safe and green commercial, industrial and residential building construction. The Company provides SG Blocks&amp;#8482;, code engineered cargo shipping containers that the Company modifies for use in construction. Rather than consuming new steel and lumber, SG Blocks&amp;#8482; capitalize on the structural engineering and design parameters a shipping container must meet and repurposes them for use in building. These products offer the construction industry a safer, greener, faster, longer lasting and more economical alternative to conventional construction methods. The Company also provides purpose-built modules (&amp;#8220;SGPBMs&amp;#8221; and, together with SG Blocks&amp;#8482;, &amp;#8220;Modules&amp;#8221;), which are prefabricated steel modular units created specifically for use in modular construction, unlike the shipping containers used to create SG Blocks&amp;#8482;.&lt;/font&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;font style="font-family: 'times new roman', times, serif; font-size: 10pt;"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;Since the Company&amp;#8217;s inception, it has generated revenues from&amp;#160;construction&amp;#160;and project management services related to the use and modification of Modules in construction.&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;font style="font-family: 'times new roman', times, serif; font-size: 10pt;"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;font style="font-family: 'times new roman', times, serif; font-size: 10pt;"&gt;Through&amp;#160;March 31, 2018, the Company has incurred an accumulated&amp;#160;deficit of $6,573,360.

ASC 606 supersedes the revenue recognition requirements in &amp;#8220;Revenue Recognition (Topic 605)&amp;#8221; (&amp;#8220;ASC 605&amp;#8221;) and requires entities to recognize revenue when control of the promised goods or services is transferred to customers at an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.

Under the modified retrospective method, the cumulative effect of applying the standard is recognized at the date of initial application. Results for reporting periods beginning after January 1, 2018 are presented under ASC 606, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under ASC 605. In implementing ASC 606, the Company was required to recalculate the revenue earned on any work in process at the implementation date and to restate the revenue and cost of revenues as if Topic 606 had been followed from the inception of the contract.&amp;#160;&amp;#160;In recalculating costs and revenue under Topic 606 guidelines, no material difference in the account balances were identified. Since a material difference was not found, no retrospective analysis of account balance changes was required. See &amp;#8220;Revenue recognition&amp;#8221; within the Summary of Significant Accounting Policies for further discussion regarding revenue from contracts with customers.&lt;/font&gt;&lt;/p&gt;&lt;/div&gt;&lt;div&gt;&amp;#160;&lt;/div&gt;&lt;div&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;font style="font-family: 'times new roman', times, serif; font-size: 10pt;"&gt;In February 2016, the FASB issued ASU No. 2016-02,&amp;#160;&lt;i&gt;Leases (Topic 842)&lt;/i&gt;. The update&amp;#8217;s principal objective is to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet. ASU 2016-02 continues to retain a distinction between finance and operating leases but requires lessees to recognize a right-of-use asset representing its right to use the underlying asset for the lease term and a corresponding lease liability on the balance sheet for all leases with terms greater than twelve months. The update is effective for fiscal years beginning after December 15, 2018. Early adoption is permitted for financial statements that have not been previously issued. The Company is currently evaluating the effects of ASU 2016-02 on the consolidated financial statements.&amp;#160;Based on the current evaluation the Company does not expect that ASU No. 2016-02,&amp;#160;&lt;i&gt;Leases (Topic 842)&amp;#160;&lt;/i&gt;will have a material impact on the Company&amp;#8217;s financial statements.&lt;/font&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;font style="font-family: 'times new roman', times, serif; font-size: 10pt;"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;font style="font-family: 'times new roman', times, serif; font-size: 10pt;"&gt;&lt;b&gt;&lt;i&gt;Accounting estimates&lt;/i&gt;&lt;/b&gt;&amp;#160;&amp;#8211; The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period.

ASU 2014-09 outlines a five-step process for revenue recognition that focuses on transfer of control, as opposed to transfer of risk and rewards, and also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenues and cash flows from contracts with customers. Major provisions include determining which goods and services are distinct and represent separate performance obligations, how variable consideration (which may include change orders and claims) is recognized, whether revenue should be recognized at a point in time or over time and ensuring the time value of money is considered in the transaction price.&lt;/font&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;font style="font-family: 'times new roman', times, serif; font-size: 10pt;"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 5.95pt 0pt 2pt; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;font style="font-family: 'times new roman', times, serif; font-size: 10pt;"&gt;ASU 2016-08, &amp;#8220;Principal versus Agent Considerations (Reporting Revenue Gross versus Net)&amp;#8221; clarifies the principal versus agent guidance in ASU 2014-09.

For those performance obligations for which revenue is recognized using a cost-to-cost input method, changes in total estimated costs, and related progress towards complete satisfaction of the performance obligation, are recognized on a cumulative catch-up basis in the period in which the revisions to the estimates are made. When the current estimate of total costs for a performance obligation indicate a loss, a provision for the entire estimated loss on the unsatisfied performance obligation is made in the period in which the loss becomes evident. For the three months ended March&amp;#160;31, 2018 and 2017, there were no changes in total estimated costs that had a significant impact to our operating results. In addition, for the three months ended March&amp;#160;31, 2018 and 2017, there were no significant losses recognized.&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; text-align: justify; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;font style="font-family: 'times new roman', times, serif; font-size: 10pt;"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; text-align: left; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;font style="font-family: 'times new roman', times, serif; font-size: 10pt;"&gt;&lt;i&gt;Remaining Unsatisfied Performance Obligations&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; text-align: left; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;font style="font-family: 'times new roman', times, serif; font-size: 10pt;"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; text-align: left; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;font style="font: 10pt/normal 'times new roman', times, serif; font-stretch: normal;"&gt;The Company&amp;#8217;s remaining unsatisfied performance obligations (&amp;#8220;RUPO&amp;#8221;) as of March 31, 2018 represent the remaining transaction price of firm contracts for which work has not been performed and excludes unexercised contract options.&amp;#160;&amp;#160;As of March 31, 2018, the aggregate amount of the transaction price allocated to remaining unsatisfied performance obligations was $102,843,237.&lt;/font&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; text-align: left; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&amp;#160;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; text-align: left; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;font style="font-family: 'times new roman', times, serif; font-size: 10pt;"&gt;The Company expects to satisfy its RUPO as of March 31, 2018 over the following period:&lt;/font&gt;&lt;/p&gt;&lt;p style="color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; font-family: 'times new roman', times, serif; font-size: 13.33px; font-style: normal; font-weight: 400; margin-top: 0px; margin-bottom: 0px; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial; font-variant-ligatures: normal; font-variant-caps: normal;"&gt;&amp;#160;&lt;/p&gt;&lt;table style="font: 10pt/normal 'times new roman', times, serif; width: 1567px; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; border-collapse: collapse; orphans: 2; widows: 2; font-size-adjust: none; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;" cellspacing="0" cellpadding="0"&gt;&lt;tr style="vertical-align: bottom; background-color: #cceeff;"&gt;&lt;td style="font: 10pt/normal 'times new roman', times, serif; width: 1379px;

Amounts included in accounts receivable are deemed to be collectible within the Company&amp;#8217;s operating cycle. Management provides an allowance for doubtful accounts based on the Company&amp;#8217;s historical losses, specific customer circumstances, and general economic conditions. Periodically, management reviews accounts receivable and adjusts the allowance based on current circumstances and charges off uncollectible receivables when all attempts to collect have been exhausted and the prospects for recovery are remote.&lt;/font&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;font style="font: 10pt/normal 'times new roman', times, serif; font-stretch: normal;"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;b&gt;&lt;i&gt;Goodwill&amp;#160;&lt;/i&gt;&lt;/b&gt;&lt;i&gt;&amp;#8211;&amp;#160;&lt;/i&gt;Goodwill represents the excess of reorganization value over fair-value of identified net assets upon emergence from bankruptcy on June 30, 2016. In accordance with the accounting guidance on goodwill, the Company performs its impairment test of goodwill at the reporting unit level each fiscal year, or more frequently if events or circumstances change that would more likely than not reduce the fair value of its reporting unit below its carrying values. The Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying amount, including goodwill. If management concludes that it is more likely than not that the fair value of the reporting unit is less than its carrying amount, management conducts a two-step quantitative goodwill impairment test. The first step of the impairment test involves comparing the fair value of the applicable reporting unit with its carrying value. If the carrying amount of the reporting unit exceeds the reporting unit&amp;#8217;s fair value, management performs the second step of the goodwill impairment test. The second step of the goodwill impairment test involves comparing the implied fair value of the affected reporting unit&amp;#8217;s goodwill with the carrying value of that goodwill. The amount by which the carrying value of the goodwill exceeds its implied fair value, if any, is recognized as an impairment loss. The Company&amp;#8217;s evaluation of goodwill completed during the year ended December 31, 2017 resulted in no impairment losses.&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&amp;#160;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; text-align: left; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;font style="font-family: 'times new roman', times, serif; font-size: 10pt;"&gt;&lt;b&gt;&lt;i&gt;Intangible assets&lt;/i&gt;&lt;/b&gt;&lt;i&gt;&amp;#160;&amp;#8211;&amp;#160;&lt;/i&gt;Intangible assets represent the preliminary assets identified upon emergence from bankruptcy and consist of $2,766,000 of proprietary knowledge and technology, which is being amortized over 20 years, and $1,113,000 of customer contracts, which is being amortized over 2.5 years. In addition, intangible assets include trademarks of $28,820, which is being amortized over 5 years. The Company evaluated intangible assets for impairment during the year ended December 31, 2017 and determined that there were no impairment losses. The accumulated amortization and amortization expense as of and for the three months ended March 31, 2018 was $1,026,889 and $147,316, respectively. The accumulated amortization and amortization expense as of and for the three months ended March 31, 2017 was $437,625 and $145,875, respectively.

text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;font style="font-family: 'times new roman', times, serif; font-size: 10pt;"&gt;The calculation of the Black-Scholes model involved the use of the fair value of the Company&amp;#8217;s common stock, estimated term, volatility, risk-free interest rates and dividend yield (if applicable). The Company developed the assumptions that were used as follows: the fair value of the Company&amp;#8217;s common stock was obtained from the terms of the recapitalization of the Company including the Exit Facility, which occurred concurrent with the Company&amp;#8217;s emergence from bankruptcy protection, as well as publicly traded market prices of the Company&amp;#8217;s common stock. The term represents the remaining contractual term of the derivative; the volatility rate was developed based on analysis of the Company&amp;#8217;s historical stock price volatility and the historical volatility rates of several other similarly situated companies (using a number of observations that was at least equal to or exceeded the number of observations in the life of the derivative financial instrument at issue); the risk free interest rates were obtained from publicly available United States Treasury yield curve rates; and the dividend yield is zero because the Company has not paid dividends and does not expect to pay dividends in the foreseeable future.&lt;/font&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;font style="font: 10pt/normal 'times new roman', times, serif; font-stretch: normal;"&gt;&amp;#160;&lt;br /&gt;&lt;/font&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial;
 text-decoration-color: initial;"&gt;&lt;b&gt;&lt;i&gt;Share-based payments&lt;/i&gt;&lt;/b&gt;&amp;#160;&amp;#8211; The Company measures the cost of services received in exchange for an award of equity instruments based on the fair value of the award. For employees and directors, the fair value of the award is measured on the grant date. The fair value amount is then recognized over the period services are required to be provided in exchange for the award, usually the vesting period.
 The Company recognizes stock-based compensation expense on a graded-vesting basis over the requisite service period for each separately vesting tranche of each award. Stock-based compensation expense to employees is reported within payroll and related expenses in the consolidated statements of operations. Stock-based compensation expense to non-employees is reported within marketing and business development expense in the consolidated statements of operations. For the three-month period ended March 31, 2018, the Company did not have any stock-based compensation expense to non-employees.&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&amp;#160;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;font style="font-family: 'times new roman', times, serif; font-size: 10pt;"&gt;&lt;b&gt;&lt;i&gt;Income taxes&lt;/i&gt;&lt;/b&gt;&lt;i&gt;&amp;#160;&amp;#8211;&amp;#160;&lt;/i&gt;The Company accounts for income taxes utilizing the asset and liability approach. Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for income taxes generally represents income taxes paid or payable for the current year plus the change in deferred taxes during the year. Deferred taxes result from the differences between the financial and tax bases of the Company&amp;#8217;s assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted.&lt;/font&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; text-align: justify; color: #000000; text-transform: none; text-indent: 0.5in; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;font style="font-family: 'times new roman', times, serif; font-size: 10pt;"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;font style="font-family: 'times new roman', times, serif; font-size: 10pt;"&gt;The calculation of tax liabilities involves dealing with uncertainties in the application of complex tax regulations. The Company recognizes liabilities for anticipated tax audit issues based on the Company&amp;#8217;s estimate of whether, and the extent to which, additional taxes will be due. If payment of these amounts ultimately proves to be unnecessary, the reversal of the liabilities would result in tax benefits being recognized in the period when the liabilities are no longer determined to be necessary. If the estimate of tax liabilities proves to be less than the ultimate assessment, a further charge to expense would result.&lt;/font&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; text-align: justify; color: #000000; text-transform: none; text-indent: 0.5in; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;font style="font-family: 'times new roman', times, serif; font-size: 10pt;"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;font style="font-family: 'times new roman', times, serif; font-size: 10pt;"&gt;The Company recognizes deferred tax liabilities and assets for the expected future tax consequences of events that have been included in the consolidated financial statements or tax returns. Deferred tax liabilities and assets are determined based on the difference between the financial statement basis and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The Company estimates the degree to which tax assets and credit carryforwards will result in a benefit based on expected profitability by tax jurisdiction. A valuation allowance for such tax assets and loss carryforwards is provided when it is determined to be more likely than not that the benefit of such deferred tax asset will not be realized in future periods. If it becomes more likely than not that a tax asset will be used, the related valuation allowance on such assets would be reduced.&lt;/font&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;font style="font-family: 'times new roman', times, serif; font-size: 10pt;"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;i&gt;Impact from the Tax Cuts and Jobs Act&lt;/i&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color:

 22, 2017. The TCJA lowered the corporate tax rate from 35.0% to 21.0% and imposed a one-time transition tax on unremitted earnings as of the end of 2017, and featured many other tax law provisions. The SEC issued Staff Accounting Bulletin No. 118 &amp;#8220;&lt;i&gt;Income Tax Implications of the Tax Cuts and Jobs Act&lt;/i&gt;&amp;#160;(&amp;#8220;SAB 118&amp;#8221;)&amp;#8221; to address the U.S. GAAP application of the TCJA. SAB 118 provides companies up to a year to finalize accounting for the impacts of the TCJA.&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&amp;#160;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;In accordance with SAB 118, the Company recognized the income tax effects of the TCJA in its consolidated financial statements for the year ended December 31, 2017. During the three months ended March 31, 2018, the Company did not have any provisional tax expense for foreign withholding taxes associated with the TCJA. The Company expects to finalize any provisional amounts associated with the TCJA over the next nine months based on ongoing assessment of its tax positions and other relevant data.&lt;/p&gt;&lt;p style="margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; font-family: 'times new roman', times, serif; font-size: 13.33px; font-style: normal; font-weight: 400; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial; font-variant-ligatures: normal; font-variant-caps: normal;"&gt;&amp;#160;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;font style="font-family: 'times new roman', times, serif; font-size: 10pt;"&gt;&lt;b&gt;&lt;i&gt;Concentrations of credit risk&lt;/i&gt;&lt;/b&gt;&lt;i&gt;&amp;#160;&amp;#8211;&amp;#160;&lt;/i&gt;Financial instruments that potentially subject the Company to concentration of credit risk consist principally of cash and cash equivalents.

The Company performs ongoing credit evaluations of its customers&amp;#8217; financial condition and, generally, requires no collateral from its customers other than normal lien rights.

Diluted net income (loss) per share is computed by dividing the net income (loss) for the period by the weighted average number of common and potentially dilutive common shares outstanding during the period. Potentially dilutive common shares consist of the common shares issuable upon the exercise of stock options and warrants. Potentially dilutive common shares are excluded from the calculation if their effect is antidilutive. At March 31, 2018, there were options and warrants to purchase 1,188,392 and 86,250 shares of common stock, respectively, outstanding that could potentially dilute future net income (loss) per share. Because the Company had a net loss as of March 31, 2018, we are prohibited from including potential common shares in the computation of diluted per share amounts. Accordingly, the Company has used the same number of shares outstanding to calculate both the basic and diluted loss per share.&lt;/font&gt;&lt;/p&gt;&lt;/div&gt;</us-gaap:EarningsPerShareTextBlock>

ASC 606 supersedes the revenue recognition requirements in &amp;#8220;Revenue Recognition (Topic 605)&amp;#8221; (&amp;#8220;ASC 605&amp;#8221;) and requires entities to recognize revenue when control of the promised goods or services is transferred to customers at an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company adopted ASC 606 as of January 1, 2018.&lt;/font&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0.55in; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;font style="font-family: 'times new roman', times, serif; font-size: 10pt;"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;font style="font-family: 'times new roman', times, serif; font-size: 10pt;"&gt;In accordance with ASC 606, the Company applied the modified retrospective method to those contracts which were not completed as of January 1, 2018. Under the modified retrospective method, the cumulative effect of applying the standard is recognized at the date of initial application. Results for reporting periods beginning after January 1, 2018 are presented under ASC 606, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under ASC 605. In implementing ASC 606, the Company was required to recalculate the revenue earned on any work in process at the implementation date and to restate the revenue and cost of revenues as if Topic 606 had been followed from the inception of the contract.&amp;#160;&amp;#160;In recalculating costs and revenue under Topic 606 guidelines, no material difference in the account balances were identified. Since a material difference was not found, no retrospective analysis of account balance changes was required.

ASU 2014-09 outlines a five-step process for revenue recognition that focuses on transfer of control, as opposed to transfer of risk and rewards, and also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenues and cash flows from contracts with customers. Major provisions include determining which goods and services are distinct and represent separate performance obligations, how variable consideration (which may include change orders and claims) is recognized, whether revenue should be recognized at a point in time or over time and ensuring the time value of money is considered in the transaction price.&lt;/font&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;font style="font-family: 'times new roman', times, serif; font-size: 10pt;"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 5.95pt 0pt 2pt; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;font style="font-family: 'times new roman', times, serif; font-size: 10pt;"&gt;ASU 2016-08, &amp;#8220;Principal versus Agent Considerations (Reporting Revenue Gross versus Net)&amp;#8221; clarifies the principal versus agent guidance in ASU 2014-09.

In accordance with the accounting guidance on goodwill, the Company performs its impairment test of goodwill at the reporting unit level each fiscal year, or more frequently if events or circumstances change that would more likely than not reduce the fair value of its reporting unit below its carrying values. The Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying amount, including goodwill. If management concludes that it is more likely than not that the fair value of the reporting unit is less than its carrying amount, management conducts a two-step quantitative goodwill impairment test. The first step of the impairment test involves comparing the fair value of the applicable reporting unit with its carrying value. If the carrying amount of the reporting unit exceeds the reporting unit&amp;#8217;s fair value, management performs the second step of the goodwill impairment test. The second step of the goodwill impairment test involves comparing the implied fair value of the affected reporting unit&amp;#8217;s goodwill with the carrying value of that goodwill. The amount by which the carrying value of the goodwill exceeds its implied fair value, if any, is recognized as an impairment loss. The Company&amp;#8217;s evaluation of goodwill completed during the year ended December 31, 2017 resulted in no impairment losses.&lt;/p&gt;&lt;/div&gt;</us-gaap:GoodwillAndIntangibleAssetsGoodwillPolicy>

The Company developed the assumptions that were used as follows: the fair value of the Company&amp;#8217;s common stock was obtained from the terms of the recapitalization of the Company including the Exit Facility, which occurred concurrent with the Company&amp;#8217;s emergence from bankruptcy protection, as well as publicly traded market prices of the Company&amp;#8217;s common stock. The term represents the remaining contractual term of the derivative; the volatility rate was developed based on analysis of the Company&amp;#8217;s historical stock price volatility and the historical volatility rates of several other similarly situated companies (using a number of observations that was at least equal to or exceeded the number of observations in the life of the derivative financial instrument at issue); the risk free interest rates were obtained from publicly available United States Treasury yield curve rates; and the dividend yield is zero because the Company has not paid dividends and does not expect to pay dividends in the foreseeable future.&lt;font style="font: 10pt/normal 'times new roman', times, serif; font-stretch: normal;"&gt;&lt;/font&gt;&lt;/font&gt;&lt;/font&gt;&lt;/p&gt;&lt;/div&gt;</us-gaap:FairValueMeasurementPolicyPolicyTextBlock>

For employees and directors, the fair value of the award is measured on the grant date. The fair value amount is then recognized over the period services are required to be provided in exchange for the award, usually the vesting period. The Company recognizes stock-based compensation expense on a graded-vesting basis over the requisite service period for each separately vesting tranche of each award. Stock-based compensation expense to employees is reported within payroll and related expenses in the consolidated statements of operations. Stock-based compensation expense to non-employees is reported within marketing and business development expense in the consolidated statements of operations. For the three-month period ended March 31, 2018, the Company did not have any stock-based compensation expense to non-employees.&lt;/p&gt;&lt;/div&gt;</us-gaap:ShareBasedCompensationOptionAndIncentivePlansPolicy>

Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for income taxes generally represents income taxes paid or payable for the current year plus the change in deferred taxes during the year. Deferred taxes result from the differences between the financial and tax bases of the Company&amp;#8217;s assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted.&lt;/font&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; text-align: justify; color: #000000; text-transform: none; text-indent: 0.5in; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;font style="font-family: 'times new roman', times, serif; font-size: 10pt;"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;font style="font-family: 'times new roman', times, serif; font-size: 10pt;"&gt;The calculation of tax liabilities involves dealing with uncertainties in the application of complex tax regulations. The Company recognizes liabilities for anticipated tax audit issues based on the Company&amp;#8217;s estimate of whether, and the extent to which, additional taxes will be due. If payment of these amounts ultimately proves to be unnecessary, the reversal of the liabilities would result in tax benefits being recognized in the period when the liabilities are no longer determined to be necessary. If the estimate of tax liabilities proves to be less than the ultimate assessment, a further charge to expense would result.&lt;/font&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; text-align: justify; color: #000000; text-transform: none; text-indent: 0.5in; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;font style="font-family: 'times new roman', times, serif; font-size: 10pt;"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;font style="font-family: 'times new roman', times, serif; font-size: 10pt;"&gt;The Company recognizes deferred tax liabilities and assets for the expected future tax consequences of events that have been included in the consolidated financial statements or tax returns. Deferred tax liabilities and assets are determined based on the difference between the financial statement basis and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The Company estimates the degree to which tax assets and credit carryforwards will result in a benefit based on expected profitability by tax jurisdiction. A valuation allowance for such tax assets and loss carryforwards is provided when it is determined to be more likely than not that the benefit of such deferred tax asset will not be realized in future periods. If it becomes more likely than not that a tax asset will be used, the related valuation allowance on such assets would be reduced.&lt;/font&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;font style="font-family: 'times new roman', times, serif; font-size: 10pt;"&gt;&amp;#160;&lt;br /&gt;&lt;/font&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;i&gt;Impact from the Tax Cuts and Jobs Act&lt;/i&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;&lt;b&gt;&lt;i&gt;&amp;#160;&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;&lt;p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"&gt;The Tax Cuts and Jobs Act (the &amp;#8220;TCJA&amp;#8221;) was enacted in the United States on December 22, 2017.

(the &#8220;Company&#8221;) was previously known as CDSI Holdings, Inc. (a Delaware corporation incorporated on December 29, 1993). On November 4, 2011, the Company&#8217;s wholly-owned subsidiary was merged with and into SG Building Blocks, Inc. (&#8220;SG Building,&#8221; formerly SG Blocks Inc.) (the &#8220;Merger&#8221;), with SG Building surviving the Merger and becoming a wholly-owned subsidiary of the Company. The Merger was a reverse merger that was accounted for as a recapitalization of SG Building as SG Building was the accounting acquirer. Accordingly, the historical financial statements presented are the financial statements of SG Building.</font></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px 0pt 0.5in; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><font style="font-family: 'times new roman', times, serif; font-size: 10pt;">&#160;</font></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><font style="font-family: 'times new roman', times, serif; font-size: 10pt;">The Company provides two main products, both of which are used to meet the growing demand for safe and green commercial, industrial and residential building construction. The Company provides SG Blocks&#8482;, code engineered cargo shipping containers that the Company modifies for use in construction. Rather than consuming new steel and lumber, SG Blocks&#8482; capitalize on the structural engineering and design parameters a shipping container must meet and repurposes them for use in building. These products offer the construction industry a safer, greener, faster, longer lasting and more economical alternative to conventional construction methods. The Company also provides purpose-built modules (&#8220;SGPBMs&#8221; and, together with SG Blocks&#8482;, &#8220;Modules&#8221;), which are prefabricated steel modular units created specifically for use in modular construction, unlike the shipping containers used to create SG Blocks&#8482;.</font></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><font style="font-family: 'times new roman', times, serif; font-size: 10pt;">&#160;</font></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">Since the Company&#8217;s inception, it has generated revenues from&#160;construction&#160;and project management services related to the use and modification of Modules in construction.</p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><font style="font-family: 'times new roman', times, serif; font-size: 10pt;">&#160;</font></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><font style="font-family: 'times new roman', times, serif; font-size: 10pt;">Through&#160;March 31, 2018, the Company has incurred an accumulated&#160;deficit of $6,573,360.

ASC 606 supersedes the revenue recognition requirements in &#8220;Revenue Recognition (Topic 605)&#8221; (&#8220;ASC 605&#8221;) and requires entities to recognize revenue when control of the promised goods or services is transferred to customers at an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company adopted ASC 606 as of January 1, 2018.</font></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0.55in; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial;

Under the modified retrospective method, the cumulative effect of applying the standard is recognized at the date of initial application. Results for reporting periods beginning after January 1, 2018 are presented under ASC 606, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under ASC 605. In implementing ASC 606, the Company was required to recalculate the revenue earned on any work in process at the implementation date and to restate the revenue and cost of revenues as if Topic 606 had been followed from the inception of the contract.&#160;&#160;In recalculating costs and revenue under Topic 606 guidelines, no material difference in the account balances were identified. Since a material difference was not found, no retrospective analysis of account balance changes was required. See &#8220;Revenue recognition&#8221; within the Summary of Significant Accounting Policies for further discussion regarding revenue from contracts with customers.</font></p></div><div>&#160;</div><div><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><font style="font-family: 'times new roman', times, serif; font-size: 10pt;">In February 2016, the FASB issued ASU No. 2016-02,&#160;<i>Leases (Topic 842)</i>. The update&#8217;s principal objective is to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet. ASU 2016-02 continues to retain a distinction between finance and operating leases but requires lessees to recognize a right-of-use asset representing its right to use the underlying asset for the lease term and a corresponding lease liability on the balance sheet for all leases with terms greater than twelve months. The update is effective for fiscal years beginning after December 15, 2018. Early adoption is permitted for financial statements that have not been previously issued. The Company is currently evaluating the effects of ASU 2016-02 on the consolidated financial statements.&#160;Based on the current evaluation the Company does not expect that ASU No. 2016-02,&#160;<i>Leases (Topic 842)&#160;</i>will have a material impact on the Company&#8217;s financial statements.</font></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><font style="font-family: 'times new roman', times, serif; font-size: 10pt;">&#160;</font></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><font style="font-family: 'times new roman', times, serif; font-size: 10pt;"><b><i>Accounting estimates</i></b>&#160;&#8211; The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period.

ASU 2014-09 outlines a five-step process for revenue recognition that focuses on transfer of control, as opposed to transfer of risk and rewards, and also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenues and cash flows from contracts with customers. Major provisions include determining which goods and services are distinct and represent separate performance obligations, how variable consideration (which may include change orders and claims) is recognized, whether revenue should be recognized at a point in time or over time and ensuring the time value of money is considered in the transaction price.</font></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><font style="font-family: 'times new roman', times, serif; font-size: 10pt;">&#160;</font></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 5.95pt 0pt 2pt; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><font style="font-family: 'times new roman', times, serif; font-size: 10pt;">ASU 2016-08, &#8220;Principal versus Agent Considerations (Reporting Revenue Gross versus Net)&#8221; clarifies the principal versus agent guidance in ASU 2014-09. ASU 2016-08 clarifies how an entity determines whether to report revenue gross or net based on whether it controls a specific good or service before it is transferred to a customer. ASU 2016-08 also reframes the indicators to focus on evidence that an entity is acting as a principal rather than as an agent.</font></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><font style="font-family: 'times new roman', times, serif; font-size: 10pt;">&#160;</font></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 7.1pt 0pt 2pt; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><font style="font-family: 'times new roman', times, serif; font-size: 10pt;">ASU 2016-10, &#8220;Identifying Performance Obligations and Licensing&#8221; amends certain aspects of ASU 2014-09.

For those performance obligations for which revenue is recognized using a cost-to-cost input method, changes in total estimated costs, and related progress towards complete satisfaction of the performance obligation, are recognized on a cumulative catch-up basis in the period in which the revisions to the estimates are made. When the current estimate of total costs for a performance obligation indicate a loss, a provision for the entire estimated loss on the unsatisfied performance obligation is made in the period in which the loss becomes evident. For the three months ended March&#160;31, 2018 and 2017, there were no changes in total estimated costs that had a significant impact to our operating results. In addition, for the three months ended March&#160;31, 2018 and 2017, there were no significant losses recognized.</p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; text-align: justify; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><font style="font-family: 'times new roman', times, serif; font-size: 10pt;">&#160;</font></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; text-align: left; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><font style="font-family: 'times new roman', times, serif; font-size: 10pt;"><i>Remaining Unsatisfied Performance Obligations</i></font></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; text-align: left; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><font style="font-family: 'times new roman', times, serif; font-size: 10pt;">&#160;</font></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; text-align: left; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><font style="font: 10pt/normal 'times new roman', times, serif; font-stretch: normal;">The Company&#8217;s remaining unsatisfied performance obligations (&#8220;RUPO&#8221;) as of March 31, 2018 represent the remaining transaction price of firm contracts for which work has not been performed and excludes unexercised contract options.&#160;&#160;As of March 31, 2018, the aggregate amount of the transaction price allocated to remaining unsatisfied performance obligations was $102,843,237.</font></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; text-align: left; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">&#160;</p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; text-align: left; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><font style="font-family: 'times new roman', times, serif; font-size: 10pt;">The Company expects to satisfy its RUPO as of March 31, 2018 over the following period:</font></p><p style="color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; font-family: 'times new roman', times, serif; font-size: 13.33px; font-style: normal; font-weight: 400; margin-top: 0px; margin-bottom: 0px; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial; font-variant-ligatures: normal; font-variant-caps: normal;">&#160;</p><table style="font: 10pt/normal 'times new roman', times, serif; width: 1567px; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; border-collapse: collapse; orphans: 2; widows: 2; font-size-adjust: none; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;" cellspacing="0" cellpadding="0"><tr style="vertical-align: bottom; background-color: #cceeff;"><td style="font: 10pt/normal 'times new roman', times, serif; width: 1379px;

In accordance with the accounting guidance on goodwill, the Company performs its impairment test of goodwill at the reporting unit level each fiscal year, or more frequently if events or circumstances change that would more likely than not reduce the fair value of its reporting unit below its carrying values. The Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying amount, including goodwill. If management concludes that it is more likely than not that the fair value of the reporting unit is less than its carrying amount, management conducts a two-step quantitative goodwill impairment test. The first step of the impairment test involves comparing the fair value of the applicable reporting unit with its carrying value. If the carrying amount of the reporting unit exceeds the reporting unit&#8217;s fair value, management performs the second step of the goodwill impairment test. The second step of the goodwill impairment test involves comparing the implied fair value of the affected reporting unit&#8217;s goodwill with the carrying value of that goodwill. The amount by which the carrying value of the goodwill exceeds its implied fair value, if any, is recognized as an impairment loss. The Company&#8217;s evaluation of goodwill completed during the year ended December 31, 2017 resulted in no impairment losses.</p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">&#160;</p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; text-align: left; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><font style="font-family: 'times new roman', times, serif; font-size: 10pt;"><b><i>Intangible assets</i></b><i>&#160;&#8211;&#160;</i>Intangible assets represent the preliminary assets identified upon emergence from bankruptcy and consist of $2,766,000 of proprietary knowledge and technology, which is being amortized over 20 years, and $1,113,000 of customer contracts, which is being amortized over 2.5 years.

The Company developed the assumptions that were used as follows: the fair value of the Company&#8217;s common stock was obtained from the terms of the recapitalization of the Company including the Exit Facility, which occurred concurrent with the Company&#8217;s emergence from bankruptcy protection, as well as publicly traded market prices of the Company&#8217;s common stock. The term represents the remaining contractual term of the derivative; the volatility rate was developed based on analysis of the Company&#8217;s historical stock price volatility and the historical volatility rates of several other similarly situated companies (using a number of observations that was at least equal to or exceeded the number of observations in the life of the derivative financial instrument at issue); the risk free interest rates were obtained from publicly available United States Treasury yield curve rates; and the dividend yield is zero because the Company has not paid dividends and does not expect to pay dividends in the foreseeable future.</font></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><font style="font: 10pt/normal 'times new roman', times, serif; font-stretch: normal;">&#160;<br /></font></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial;

For employees and directors, the fair value of the award is measured on the grant date. The fair value amount is then recognized over the period services are required to be provided in exchange for the award, usually the vesting period.
 The Company recognizes stock-based compensation expense on a graded-vesting basis over the requisite service period for each separately vesting tranche of each award. Stock-based compensation expense to employees is reported within payroll and related expenses in the consolidated statements of operations. Stock-based compensation expense to non-employees is reported within marketing and business development expense in the consolidated statements of operations. For the three-month period ended March 31, 2018, the Company did not have any stock-based compensation expense to non-employees.</p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">&#160;</p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><font style="font-family: 'times new roman', times, serif; font-size: 10pt;"><b><i>Income taxes</i></b><i>&#160;&#8211;&#160;</i>The Company accounts for income taxes utilizing the asset and liability approach. Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for income taxes generally represents income taxes paid or payable for the current year plus the change in deferred taxes during the year. Deferred taxes result from the differences between the financial and tax bases of the Company&#8217;s assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted.</font></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; text-align: justify; color: #000000; text-transform: none; text-indent: 0.5in; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><font style="font-family: 'times new roman', times, serif; font-size: 10pt;">&#160;</font></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><font style="font-family: 'times new roman', times, serif; font-size: 10pt;">The calculation of tax liabilities involves dealing with uncertainties in the application of complex tax regulations. The Company recognizes liabilities for anticipated tax audit issues based on the Company&#8217;s estimate of whether, and the extent to which, additional taxes will be due. If payment of these amounts ultimately proves to be unnecessary, the reversal of the liabilities would result in tax benefits being recognized in the period when the liabilities are no longer determined to be necessary. If the estimate of tax liabilities proves to be less than the ultimate assessment, a further charge to expense would result.</font></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; text-align: justify; color: #000000; text-transform: none; text-indent: 0.5in; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><font style="font-family: 'times new roman', times, serif; font-size: 10pt;">&#160;</font></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><font style="font-family: 'times new roman', times, serif; font-size: 10pt;">The Company recognizes deferred tax liabilities and assets for the expected future tax consequences of events that have been included in the consolidated financial statements or tax returns. Deferred tax liabilities and assets are determined based on the difference between the financial statement basis and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The Company estimates the degree to which tax assets and credit carryforwards will result in a benefit based on expected profitability by tax jurisdiction. A valuation allowance for such tax assets and loss carryforwards is provided when it is determined to be more likely than not that the benefit of such deferred tax asset will not be realized in future periods. If it becomes more likely than not that a tax asset will be used, the related valuation allowance on such assets would be reduced.</font></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><font style="font-family: 'times new roman', times, serif; font-size: 10pt;">&#160;</font></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><i>Impact from the Tax Cuts and Jobs Act</i></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color:

The SEC issued Staff Accounting Bulletin No. 118 &#8220;<i>Income Tax Implications of the Tax Cuts and Jobs Act</i>&#160;(&#8220;SAB 118&#8221;)&#8221; to address the U.S. GAAP application of the TCJA.

Diluted net income (loss) per share is computed by dividing the net income (loss) for the period by the weighted average number of common and potentially dilutive common shares outstanding during the period. Potentially dilutive common shares consist of the common shares issuable upon the exercise of stock options and warrants. Potentially dilutive common shares are excluded from the calculation if their effect is antidilutive. At March 31, 2018, there were options and warrants to purchase 1,188,392 and 86,250 shares of common stock, respectively, outstanding that could potentially dilute future net income (loss) per share. Because the Company had a net loss as of March 31, 2018, we are prohibited from including potential common shares in the computation of diluted per share amounts. Accordingly, the Company has used the same number of shares outstanding to calculate both the basic and diluted loss per share.</font></p></div><span></span>

ASC 606 supersedes the revenue recognition requirements in &#8220;Revenue Recognition (Topic 605)&#8221; (&#8220;ASC 605&#8221;) and requires entities to recognize revenue when control of the promised goods or services is transferred to customers at an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.

Under the modified retrospective method, the cumulative effect of applying the standard is recognized at the date of initial application. Results for reporting periods beginning after January 1, 2018 are presented under ASC 606, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under ASC 605. In implementing ASC 606, the Company was required to recalculate the revenue earned on any work in process at the implementation date and to restate the revenue and cost of revenues as if Topic 606 had been followed from the inception of the contract.&#160;&#160;In recalculating costs and revenue under Topic 606 guidelines, no material difference in the account balances were identified. Since a material difference was not found, no retrospective analysis of account balance changes was required.

For those performance obligations for which revenue is recognized using a cost-to-cost input method, changes in total estimated costs, and related progress towards complete satisfaction of the performance obligation, are recognized on a cumulative catch-up basis in the period in which the revisions to the estimates are made. When the current estimate of total costs for a performance obligation indicate a loss, a provision for the entire estimated loss on the unsatisfied performance obligation is made in the period in which the loss becomes evident. For the three months ended March&#160;31, 2018 and 2017, there were no changes in total estimated costs that had a significant impact to our operating results. In addition, for the three months ended March&#160;31, 2018 and 2017, there were no significant losses recognized.</p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; text-align: justify; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><font style="font-family: 'times new roman', times, serif; font-size: 10pt;">&#160;</font></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; text-align: left; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><font style="font-family: 'times new roman', times, serif; font-size: 10pt;"><i>Remaining Unsatisfied Performance Obligations</i></font></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; text-align: left; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><font style="font-family: 'times new roman', times, serif; font-size: 10pt;">&#160;</font></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; text-align: left; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><font style="font: 10pt/normal 'times new roman', times, serif; font-stretch: normal;">The Company&#8217;s remaining unsatisfied performance obligations (&#8220;RUPO&#8221;) as of March 31, 2018 represent the remaining transaction price of firm contracts for which work has not been performed and excludes unexercised contract options.&#160;&#160;As of March 31, 2018, the aggregate amount of the transaction price allocated to remaining unsatisfied performance obligations was $102,843,237.</font></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; text-align: left; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">&#160;</p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; text-align: left; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><font style="font-family: 'times new roman', times, serif; font-size: 10pt;">The Company expects to satisfy its RUPO as of

The Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying amount, including goodwill. If management concludes that it is more likely than not that the fair value of the reporting unit is less than its carrying amount, management conducts a two-step quantitative goodwill impairment test. The first step of the impairment test involves comparing the fair value of the applicable reporting unit with its carrying value. If the carrying amount of the reporting unit exceeds the reporting unit&#8217;s fair value, management performs the second step of the goodwill impairment test. The second step of the goodwill impairment test involves comparing the implied fair value of the affected reporting unit&#8217;s goodwill with the carrying value of that goodwill. The amount by which the carrying value of the goodwill exceeds its implied fair value, if any, is recognized as an impairment loss. The Company&#8217;s evaluation of goodwill completed during the year ended December 31, 2017 resulted in no impairment losses.</p></div><span></span>

The term represents the remaining contractual term of the derivative; the volatility rate was developed based on analysis of the Company&#8217;s historical stock price volatility and the historical volatility rates of several other similarly situated companies (using a number of observations that was at least equal to or exceeded the number of observations in the life of the derivative financial instrument at issue); the risk free interest rates were obtained from publicly available United States Treasury yield curve rates; and the dividend yield is zero because the Company has not paid dividends and does not expect to pay dividends in the foreseeable future.<font style="font: 10pt/normal 'times new roman', times, serif; font-stretch: normal;"></font></font></font></p></div><span></span>

Deferred taxes result from the differences between the financial and tax bases of the Company&#8217;s assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted.</font></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; text-align: justify; color: #000000; text-transform: none; text-indent: 0.5in; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><font style="font-family: 'times new roman', times, serif; font-size: 10pt;">&#160;</font></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><font style="font-family: 'times new roman', times, serif; font-size: 10pt;">The calculation of tax liabilities involves dealing with uncertainties in the application of complex tax regulations. The Company recognizes liabilities for anticipated tax audit issues based on the Company&#8217;s estimate of whether, and the extent to which, additional taxes will be due. If payment of these amounts ultimately proves to be unnecessary, the reversal of the liabilities would result in tax benefits being recognized in the period when the liabilities are no longer determined to be necessary. If the estimate of tax liabilities proves to be less than the ultimate assessment, a further charge to expense would result.</font></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; text-align: justify; color: #000000; text-transform: none; text-indent: 0.5in; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><font style="font-family: 'times new roman', times, serif; font-size: 10pt;">&#160;</font></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><font style="font-family: 'times new roman', times, serif; font-size: 10pt;">The Company recognizes deferred tax liabilities and assets for the expected future tax consequences of events that have been included in the consolidated financial statements or tax returns. Deferred tax liabilities and assets are determined based on the difference between the financial statement basis and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The Company estimates the degree to which tax assets and credit carryforwards will result in a benefit based on expected profitability by tax jurisdiction. A valuation allowance for such tax assets and loss carryforwards is provided when it is determined to be more likely than not that the benefit of such deferred tax asset will not be realized in future periods. If it becomes more likely than not that a tax asset will be used, the related valuation allowance on such assets would be reduced.</font></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><font style="font-family: 'times new roman', times, serif; font-size: 10pt;">&#160;<br /></font></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><i>Impact from the Tax Cuts and Jobs Act</i></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><b><i>&#160;</i></b></p><p style="font: 10pt/normal 'times new roman', times, serif; margin: 0pt 0px; color: #000000; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; orphans: 2; widows: 2; font-stretch: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">The Tax Cuts and Jobs Act (the &#8220;TCJA&#8221;) was enacted in the United States on December 22, 2017. The TCJA lowered the corporate tax rate from 35.0% to 21.0% and imposed a one-time transition tax on unremitted earnings as of the end of 2017, and featured many other tax law provisions. The SEC issued Staff Accounting Bulletin No. 118 &#8220;<i>Income Tax Implications of the Tax Cuts and Jobs Act</i>&#160;(&#8220;SAB 118&#8221;)&#8221; to address the U.S. GAAP application of the TCJA.

During the three months ended March 31, 2018, the Company did not have any provisional tax expense for foreign withholding taxes associated with the TCJA. The Company expects to finalize any provisional amounts associated with the TCJA over the next nine months based on ongoing assessment of its tax positions and other relevant data.</p></div><span></span>
