An entity will, therefore, perform the goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and recognizing an impairment charge for the amount by which the carrying amount exceeds the fair value, not to exceed the total amount of goodwill allocated to the reporting unit. An entity still has the option to perform a qualitative assessment to determine if the quantitative impairment test is necessary. The ASU is effective for interim and annual periods beginning after December 15, 2019, with early adoption permitted. Adoption of the ASU is on a prospective basis. Based on current evaluation, the Company does not expect that ASU No. <span id="fs_XF2T4NX9HC00000000000000000000fs">2017</span>-<span id="fs_57J61YWJDS00000000000000000000fs">04</span> will have a material impact on the Company&#8217;s financial statements.</span></p>

For those performance obligations for which revenue is recognized using a cost-to-cost input method, changes in total estimated costs, and related progress toward 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.&#160;</span></span></p>

For employees and directors, including non-employee directors, the fair value of a stock option 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 and all directors 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.&#160;</span><span style="font-family: 'Times New Roman'; font-size: 10pt;"><br/></span></p>

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.</span></p>

<p style="margin: 0pt 0pt 0pt 36pt;"><span style="font-family: 'Times New Roman'; 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.</span></p>

The Company&#160;assesses its liabilities and contingencies in connection with outstanding legal proceedings utilizing the latest information available. Where it is probable that the Company will incur a loss and the amount of the loss can be reasonably estimated, the Company records a liability in its consolidated financial statements. These legal accruals may be increased or decreased to reflect any relevant developments on a quarterly basis. Where a loss is not probable or the amount of the loss is not estimable, the Company does not record an accrual, consistent with applicable accounting guidance. Based on information currently available to the Company, advice of counsel, and available insurance coverage, the Company believes that its established accruals are adequate and the liabilities arising from the legal proceedings will not have a material adverse effect on its consolidated financial condition. The Company notes, however, that in light of the inherent uncertainty in legal proceedings there</span><span style="font-size: 13.3333px;">&#160;</span>can be no assurance that the ultimate resolution of a matter will not exceed established accruals. As a result, the outcome of a particular matter or a combination of matters may be material to the Company&#8217;s results of operations for a particular period, depending upon the size of the loss or the Company&#8217;s income for that particular period.&#160;&#160;</span></p>

The Company claims that HOLA Community Partners owes the Company certain amounts due for work performed on the HOLA Project and extra costs incurred due to delays and impacts caused by HOLA Community Partners. HOLA Community Partners disputes the amounts owed, and claims that the Company failed to meet its contractual obligations. The parties are in ongoing settlement discussions. Neither party has commenced litigation as of the date of these condensed consolidated financial statements.&#160;</span></p>

We currently have a Form S-<span id="fs_C90CCFAEJK00000000000000000000fs">3</span> shelf registration statement on file with the Securities and Exchange Commission.

Each phase is independent of the other, but builds through a progression of concept through delivery of a completed structure. These phases may be embodied in a single contract or in separate contracts, which is typical of a design build process model.

The decrease&#160;in backlog at <span id="fs_YZTLRL0DSW00000000000000000000FM">March 31, 2019</span> from the prior year is primarily attributable to work in progress or completed contracts during the first quarter for approximately $<span id="fs_7T9H679PVK00000000000000000000fs">1,735,000</span>.</span></p>

<p style="margin: 0pt; text-indent: 36pt;"><span style="font-family: 'Times New Roman'; font-size: 10pt;"> <span style="font-size: 10.0pt; font-family: 'Times New Roman',serif; mso-fareast-font-family: 'Times New Roman'; mso-ansi-language: EN-US; mso-fareast-language: EN-US; mso-bidi-language: AR-SA;">Our condensed consolidated financial statements have been prepared using generally accepted accounting principles in the United States of America (&#8220;GAAP&#8221;), 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 <span id="fs_7MUUZT80GG00000000000000000000fs">2018</span> Form 10-K. There have been no material changes in critical accounting policies from those disclosed in the <span id="fs_Y6H01R2FQ800000000000000000000fs">2018</span> Form 10-K.&#160;</span></span></p>

<p style="margin: 0pt; text-indent: 36pt;"><span style="font-family: 'Times New Roman'; font-size: 10pt;">In addition to our results under GAAP, we also present EBITDA and Adjusted EBITDA for historical periods. EBITDA and Adjusted EBITDA are non-GAAP financial measures and have been presented as supplemental measures of financial performance that are not required by, or presented in accordance with, GAAP. We calculate EBITDA as net income (loss) before interest expense, income tax benefit (expense), depreciation and amortization. We calculate Adjusted EBITDA as EBITDA before certain non-recurring adjustments such as stock-based compensation expense.</span></p>
<p style="margin: 0pt; text-indent: 36pt;"><span style="font-family: 'Times New Roman'; font-size: 10pt;">&#160;</span></p>
<p style="margin: 0pt; text-indent: 36pt;"><span style="font-family: 'Times New Roman'; font-size: 10pt;">EBITDA and Adjusted EBITDA are presented because they are important metrics used by management as <span id="fs_9HHCWX0MRK00000000000000000000fs">one</span> of the means by which it assesses our financial performance. EBITDA and Adjusted EBITDA are also frequently used by analysts, investors and other interested parties to evaluate companies in our industry. These measures, when used in conjunction with related GAAP financial measures, provide investors with an additional financial analytical framework that may be useful in assessing us and our results of operations.</span></p>
<p style="margin: 0pt; text-indent: 36pt;"><span style="font-family: 'Times New Roman'; font-size: 10pt;">&#160;</span></p>
<p style="margin: 0pt; text-indent: 36pt;"><span style="font-family: 'Times New Roman'; font-size: 10pt;">EBITDA and Adjusted EBITDA have certain limitations. EBITDA and Adjusted EBITDA should not be considered as alternatives to net income (loss), or any other measures of financial performance derived in accordance with GAAP. These measures also should not be construed as an inference that our future results will be unaffected by unusual o</span><span style="font-family: 'Times New Roman'; font-size: 10pt;">r non-recurring items for which these non-GAAP measures make adjustments. Additionally, EBITDA and Adjusted EBITDA are not intended to be liquidity measures because of certain limitations, including, but not limited to:</span></p>

The Company completed an equity offering in April 2019, which resulted in net proceeds of approximately $&lt;span&gt;692,248&lt;/span&gt;. See Note &lt;span id="fs_BLKIF9HC3400000000000000000000fs"&gt;13&lt;/span&gt; for a discussion of the offering. There is, however, no assurance the Company will be successful in meeting its capital requirements prior to becoming cash flow positive.&lt;/span&gt;&lt;/span&gt;&lt;span style="font-size: 10.0pt;"&gt;&lt;span style="font-family: 'times new roman', times;"&gt;&#160;The Company&#160;does not have any additional sources secured for future funding, and if it is unable to raise the necessary capital at the times it requires such funding, it may need to materially change its business plan, including delaying implementation of aspects of such business plan or curtailing or abandoning such business plan altogether.&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;

An entity will, therefore, perform the goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and recognizing an impairment charge for the amount by which the carrying amount exceeds the fair value, not to exceed the total amount of goodwill allocated to the reporting unit. An entity still has the option to perform a qualitative assessment to determine if the quantitative impairment test is necessary. The ASU is effective for interim and annual periods beginning after December 15, 2019, with early adoption permitted. Adoption of the ASU is on a prospective basis.

The recognition of revenue aligns with the timing of when promised goods or services are transferred to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. &lt;/span&gt;&lt;span style="font-size: 10.0pt;"&gt;To achieve this core principle, the Company applies the following five steps in accordance with its revenue policy:&lt;/span&gt;&lt;br/&gt;&lt;/p&gt;

For those performance obligations for which revenue is recognized using a cost-to-cost input method, changes in total estimated costs, and related progress toward 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.&#160;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;

Amounts included in accounts receivable are deemed to be collectible within the Company&#x2019;s operating cycle.

Management provides an allowance for doubtful accounts based on the Company&#x2019;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. Recoveries are recognized when they are received. Actual collection losses may differ from the Company&#x2019;s estimates and could be material to its consolidated financial position, result of operations, and cash flows.&lt;/span&gt;&#160;&lt;/span&gt;&lt;/p&gt;

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 &lt;span id="fs_TRNKIGEO7400000000000000000000fs"&gt;two&lt;/span&gt;-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&#x2019;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&#x2019;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&#x2019;s evaluation of goodwill completed during the year ended &lt;span id="fs_C1QOODBGAO00000000000000000000FM"&gt;December 31, 2018&lt;/span&gt; resulted in no impairment losses.&lt;/span&gt;&lt;/p&gt;

For employees and directors, including non-employee directors, the fair value of a stock option 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 and all directors 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.&#160;&lt;/span&gt;&lt;span style="font-family: 'Times New Roman'; font-size: 10pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin: 0pt 0pt 0pt 36pt;"&gt;&lt;span style="font-family: 'Times New Roman', serif; font-size: 10pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/p&gt;

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&#x2019;s assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin: 0pt; text-indent: 36pt;"&gt;&lt;span style="font-family: 'Times New Roman'; font-size: 10pt;"&gt;&#160;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin: 0pt 0pt 0pt 36pt;"&gt;&lt;span style="font-family: 'Times New Roman'; 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&#x2019;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;/span&gt;&lt;/p&gt;

The Company places its cash with high credit quality institutions. At times, such amounts may be in excess of the FDIC insurance limits. The Company has not experienced any losses in its&#160;account and believes that it is not exposed to any significant credit risk on the account.&lt;/span&gt;&lt;/p&gt;

An entity will, therefore, perform the goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and recognizing an impairment charge for the amount by which the carrying amount exceeds the fair value, not to exceed the total amount of goodwill allocated to the reporting unit. An entity still has the option to perform a qualitative assessment to determine if the quantitative impairment test is necessary. The ASU is effective for interim and annual periods beginning after December 15, 2019, with early adoption permitted. Adoption of the ASU is on a prospective basis. Based on current evaluation, the Company does not expect that ASU No. &lt;span id="fs_XF2T4NX9HC00000000000000000000fs"&gt;2017&lt;/span&gt;-&lt;span id="fs_57J61YWJDS00000000000000000000fs"&gt;04&lt;/span&gt; will have a material impact on the Company&#x2019;s financial statements.&lt;/span&gt;&lt;/p&gt;

The Company determines, at contract inception, whether it will transfer control of a promised good or service over time or at a point in time&#x2014;regardless of the length of contract or other factors. The recognition of revenue aligns with the timing of when promised goods or services are transferred to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. &lt;/span&gt;&lt;span style="font-size: 10.0pt;"&gt;To achieve this core principle, the Company applies the following five steps in accordance with its revenue policy:&lt;/span&gt;&lt;br/&gt;&lt;/p&gt;

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.&#160;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;

Such amounts are recoverable from customers based upon various measures of performance, including achievement of certain milestones, completion of specified units or completion of a contract.

Contract liabilities additionally include advanced payments from customers on certain contracts. Contract liabilities decrease as the Company recognizes revenue from the satisfaction of the related performance obligation.

Management provides an allowance for doubtful accounts based on the Company&#x2019;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. Recoveries are recognized when they are received. Actual collection losses may differ from the Company&#x2019;s estimates and could be material to its consolidated financial position, result of operations, and cash flows.&lt;/span&gt;&#160;&lt;/span&gt;&lt;/p&gt;

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. Recoveries are recognized when they are received. Actual collection losses may differ from the Company&#x2019;s estimates and could be material to its consolidated financial position, result of operations, and cash flows.&lt;/span&gt;&#160;&lt;/span&gt;&lt;/p&gt;

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 &lt;span id="fs_TRNKIGEO7400000000000000000000fs"&gt;two&lt;/span&gt;-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&#x2019;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&#x2019;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&#x2019;s evaluation of goodwill completed during the year ended &lt;span id="fs_C1QOODBGAO00000000000000000000FM"&gt;December 31, 2018&lt;/span&gt; resulted in no impairment losses.&lt;/span&gt;&lt;/p&gt;

For employees and directors, including non-employee directors, the fair value of a stock option award is measured on the grant date.

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.

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&#x2019;s assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted.&lt;/span&gt;&lt;/p&gt;

&lt;p style="margin: 0pt 0pt 0pt 36pt;"&gt;&lt;span style="font-family: 'Times New Roman'; 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&#x2019;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;/span&gt;&lt;/p&gt;

The Company&#160;assesses its liabilities and contingencies in connection with outstanding legal proceedings utilizing the latest information available. Where it is probable that the Company will incur a loss and the amount of the loss can be reasonably estimated, the Company records a liability in its consolidated financial statements. These legal accruals may be increased or decreased to reflect any relevant developments on a quarterly basis. Where a loss is not probable or the amount of the loss is not estimable, the Company does not record an accrual, consistent with applicable accounting guidance. Based on information currently available to the Company, advice of counsel, and available insurance coverage, the Company believes that its established accruals are adequate and the liabilities arising from the legal proceedings will not have a material adverse effect on its consolidated financial condition. The Company notes, however, that in light of the inherent uncertainty in legal proceedings there&lt;/span&gt;&lt;span style="font-size: 13.3333px;"&gt;&#160;&lt;/span&gt;can be no assurance that the ultimate resolution of a matter will not exceed established accruals. As a result, the outcome of a particular matter or a combination of matters may be material to the Company&#x2019;s results of operations for a particular period, depending upon the size of the loss or the Company&#x2019;s income for that particular period.&#160;&#160;&lt;/span&gt;&lt;/p&gt;

(&#x201c;Phipps&#x201d;). The lawsuit was filed as Pizzarotti, LLC. v. Phipps &amp;amp; Co., et al., Index No. &lt;span id="fs_7LEI31G1KW00000000000000000000fs"&gt;653996&lt;/span&gt;/&lt;span id="fs_E75SYBQ67400000000000000000000fs"&gt;2018&lt;/span&gt; and commenced in the Supreme Court of the State of New York for the County of New York.&lt;/span&gt;&lt;/p&gt;

The Assignment Agreement was ultimately terminated, and the Company returned all payments to Phipps. Notwithstanding the above, Pizzarotti has sued seeking damages for nonperformance of the sub-contracted work and the return of a $500,000&#160;payment from Phipps.&lt;/span&gt;&lt;/p&gt;

The Company is currently unable to predict the possible loss or range of loss, if any, associated with the resolution of this litigation, and, accordingly, the Company has made no provision related to this matter in the condensed consolidated financial statements.&lt;/span&gt;&lt;/p&gt;

The Company&#x2019;s complaint alleged that Teton failed to comply with specific product requirements with respect to the modular units for the HOLA Project and that Teton&#x2019;s delay and product quality resulted in damages. The Company&#x2019;s claims include breach of contract, negligence, and breach of express warranty. The lawsuit was filed as &lt;i style="mso-bidi-font-style: normal;"&gt;SG Blocks, Inc. v. Teton Buildings, LLC&lt;/i&gt;; Case Number &lt;span id="fs_QX4L1793J400000000000000000000fs"&gt;2019&lt;/span&gt;-&lt;span id="fs_RKW32KFZSW00000000000000000000fs"&gt;02827&lt;/span&gt; in the United States District Court for the Southern District of Texas.&#160;&lt;/span&gt;&lt;/p&gt;

As with any litigation at this early stage, the cost of litigating and the outcome remain uncertain.&#160;&lt;/span&gt;&lt;/p&gt;

The Company claims that HOLA Community Partners owes the Company certain amounts due for work performed on the HOLA Project and extra costs incurred due to delays and impacts caused by HOLA Community Partners. HOLA Community Partners disputes the amounts owed, and claims that the Company failed to meet its contractual obligations. The parties are in ongoing settlement discussions. Neither party has commenced litigation as of the date of these condensed consolidated financial statements.&#160;&lt;/span&gt;&lt;/p&gt;

Defending lawsuits requires significant management attention and financial resources and the outcome of any litigation, including the matters described above, is inherently uncertain. The Company does not, however, currently expect that the costs to resolve these routine matters will have a material adverse effect on its consolidated financial position, results of operations, or cash flows.&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;

The Company believes that it has adequate cash balances to meet <span style="background-color: #ffffff;">obligations coming due in the next <span style="border-left: none; border-right: none;"><span id="fs_DCXXHB1QB400000000000000000000fs">twelve</span></span> months</span> </span><span style="color: #000000;">and further intends to meet its capital needs by containing costs and entering into strategic alliances, as well as exploring other options, including the possibility of raising additional debt or equity capital as necessary. The Company completed an equity offering in April 2019, which resulted in net proceeds of approximately $<span>692,248</span>. See Note <span id="fs_BLKIF9HC3400000000000000000000fs">13</span> for a discussion of the offering. There is, however, no assurance the Company will be successful in meeting its capital requirements prior to becoming cash flow positive.</span></span><span style="font-size: 10.0pt;"><span style="font-family: 'times new roman', times;">&#160;The Company&#160;does not have any additional sources secured for future funding, and if it is unable to raise the necessary capital at the times it requires such funding, it may need to materially change its business plan, including delaying implementation of aspects of such business plan or curtailing or abandoning such business plan altogether.</span></span></p>

The Company determines, at contract inception, whether it will transfer control of a promised good or service over time or at a point in time&#8212;regardless of the length of contract or other factors. The recognition of revenue aligns with the timing of when promised goods or services are transferred to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. </span><span style="font-size: 10.0pt;">To achieve this core principle, the Company applies the following five steps in accordance with its revenue policy:</span><br/></p>

For those performance obligations for which revenue is recognized using a cost-to-cost input method, changes in total estimated costs, and related progress toward 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.&#160;</span></span></p>

Management provides an allowance for doubtful accounts based on the Company&#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. Recoveries are recognized when they are received. Actual collection losses may differ from the Company&#8217;s estimates and could be material to its consolidated financial position, result of operations, and cash flows.</span>&#160;</span></p>

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 <span id="fs_TRNKIGEO7400000000000000000000fs">two</span>-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 <span id="fs_C1QOODBGAO00000000000000000000FM">December 31, 2018</span> resulted in no impairment losses.</span></p>

The Company classifies as assets or liabilities any contracts that (i) require net-cash settlement (including a requirement to net cash settle the contract if any event occurs and if that event is outside the Company&#8217;s control) or (ii) gives the counterparty a choice of net-cash settlement or&#160;settlement shares (physical settlement or net-cash settlement). <span style="background-color: #ffffff;">The Company assesses classification of common stock purchase warrants and other free standing derivatives at each reporting date to determine whether a change in classification between assets and liabilities or equity is required.</span></span></span></span></p>

For employees and directors, including non-employee directors, the fair value of a stock option 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 and all directors 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.&#160;</span><span style="font-family: 'Times New Roman'; font-size: 10pt;"><br/></span></p>

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.</span></p>

<p style="margin: 0pt 0pt 0pt 36pt;"><span style="font-family: 'Times New Roman'; 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.</span></p>

The Company places its cash with high credit quality institutions. At times, such amounts may be in excess of the FDIC insurance limits. The Company has not experienced any losses in its&#160;account and believes that it is not exposed to any significant credit risk on the account.</span></p>

<p style="margin: 0pt 0pt 0pt 36pt;"><span style="font-family: 'Times New Roman'; font-size: 10pt;">With respect to receivables, concentrations of credit risk are limited to a few customers in the construction industry.

The Company&#160;assesses its liabilities and contingencies in connection with outstanding legal proceedings utilizing the latest information available. Where it is probable that the Company will incur a loss and the amount of the loss can be reasonably estimated, the Company records a liability in its consolidated financial statements. These legal accruals may be increased or decreased to reflect any relevant developments on a quarterly basis. Where a loss is not probable or the amount of the loss is not estimable, the Company does not record an accrual, consistent with applicable accounting guidance. Based on information currently available to the Company, advice of counsel, and available insurance coverage, the Company believes that its established accruals are adequate and the liabilities arising from the legal proceedings will not have a material adverse effect on its consolidated financial condition. The Company notes, however, that in light of the inherent uncertainty in legal proceedings there</span><span style="font-size: 13.3333px;">&#160;</span>can be no assurance that the ultimate resolution of a matter will not exceed established accruals. As a result, the outcome of a particular matter or a combination of matters may be material to the Company&#8217;s results of operations for a particular period, depending upon the size of the loss or the Company&#8217;s income for that particular period.&#160;&#160;</span></p>

The Assignment Agreement was ultimately terminated, and the Company returned all payments to Phipps.

The Company determines, at contract inception, whether it will transfer control of a promised good or service over time or at a point in time&#8212;regardless of the length of contract or other factors. The recognition of revenue aligns with the timing of when promised goods or services are transferred to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. </span><span style="font-size: 10.0pt;">To achieve this core principle, the Company applies the following five steps in accordance with its revenue policy:</span><br/></p>

For those performance obligations for which revenue is recognized using a cost-to-cost input method, changes in total estimated costs, and related progress toward 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.&#160;</span></span></p>

The amount by which the carrying value of the goodwill exceeds its implied fair value, if any, is recognized as an impairment loss.

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.

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.</span></p>

<p style="margin: 0pt 0pt 0pt 36pt;"><span style="font-family: 'Times New Roman'; 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.</span></p>

Volatility also may be defined as a probability-weighted measure of the dispersion of returns about the mean. The volatility of a share price is the standard deviation of the continuously compounded rates of return on the share over a specified period. That is the same as the standard deviation of the differences in the natural logarithms of the stock prices plus dividends, if any, over the period.</p></div>
