Dec. 31, 2018
Accounting Policies [Abstract] |
Basis of consolidation | Basis of presentation and principals of consolidation – The consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) and the applicable rules and regulations of the United States Securities and Exchange Commission (“SEC”) and include the accounts of the Company and its wholly owned subsidiaries, SG Building Blocks, Inc. and SG Residential, Inc. All intercompany balances and transactions are eliminated. Certain prior period amounts have been reclassified to conform to the current period’s presentation.
Recently adopted accounting pronouncements | Recently adopted accounting pronouncements - New accounting pronouncements implemented by the Company during the year ended December 31, 2018 are discussed below or in the related notes, where appropriate. In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606)” (“ASC 606”). ASC 606 supersedes the revenue recognition requirements in “Revenue Recognition (Topic 605)” (“ASC 605”) 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. In accordance with ASC 606, the Company selected 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 were not adjusted and continue to be reported in accordance with the Company’s 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 ASC 606 had been followed from the inception of the contract. In recalculating costs and revenue under ASC 606 guidelines, no material differences in the account balances were identified. Since material differences were not found, no retrospective analysis of account balance changes was required. See “Revenue recognition” below for further discussion regarding revenue from contracts with customers. Recently issued accounting pronouncements not yet adopted - New accounting pronouncements requiring implementation in future periods are discussed below. In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). The update’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 their 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. In July 2018, the FASB issued ASU No. 2018-11, “Leases (Topic 842): Targeted Improvements” (“ASU 2018-11”), which provides entities with an additional transition method. Under ASU 2018-11, entities have the option of recognizing the cumulative effect of applying the new standard as an adjustment to beginning retained earnings in the year of adoption while continuing to present all prior periods under previous lease accounting guidance. In July 2018, the FASB also issued ASU No. 2018-10, “Codification Improvements to Topic 842, Leases” (“ASU 2018-10”), which clarifies how to apply certain aspects of ASU 2016-02. The Company will adopt ASU 2016-02, ASU 2018-10 and ASU 2018-11 beginning January 1, 2019. The Company is currently evaluating the effects of ASU 2016-02 on the consolidated financial statements. The Company had no operating lease agreements as of December 31, 2018. Based on the current evaluation, the Company does not expect that ASU No. 2016-02 will have a material impact on the Company’s financial statements. In January 2017, the FASB issued ASU No. 2017-04, “Simplifying the Test for Goodwill Impairment” (“ASU 2017-04”), to simplify the test for goodwill impairment by removing Step 2. 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. 2017-04 will have a material impact on the Company’s financial statements. In June 2018, the FASB issued ASU No. 2018-07, “Compensation — Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting” (“ASU 2018-07”), which expands the scope of Topic 718 to include all share-based payment transactions for acquiring goods and services from nonemployees. ASU 2018-07 specifies that Topic 718 applies to all share-based payment transactions in which the grantor acquires goods and services to be used or consumed in its own operations by issuing share-based payment awards. ASU 2018-07 also clarifies that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under ASC 606. ASU 2018-07 is effective for the Company beginning January 1, 2019, with early adoption permitted. The Company is currently evaluating the potential impact of adopting this guidance on our consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-13, “Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement” (“ASU 2018-13”). This ASU amends ASC 820 to add, remove and modify certain disclosure requirements for fair value measurements. For example, public companies will be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. ASU 2018-13 is effective for interim and annual reporting periods beginning after December 15, 2019, with early adoption permitted. Management does not expect the adoption of ASU 2018-13 to have a material impact on the Company’s financial position, results of operations or cash flow.
Accounting estimates | Accounting estimates – The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“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. Significant areas that require the Company to make estimates include revenue recognition, stock-based compensation, warrant liabilities and allowance for doubtful accounts. Actual results could differ from those estimates.
Operating cycle | Operating cycle – The length of the Company’s contracts varies, but is typically between six to twelve months. In some instances, the length of the contract may exceed twelve months. Assets and liabilities relating to current and long-term contracts are included in current assets and current liabilities, respectively, in the accompanying balance sheets as they will be liquidated in the normal course of contract completion, which at times could exceed one year.
Revenue recognition | Revenue recognition – On January 1, 2018, the Company adopted the following ASUs: ASU 2014-09, “Revenue from Contracts with Customers” outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry specific guidance. 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. ASU 2016-08, “Principal versus Agent Considerations (Reporting Revenue Gross versus Net)” 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. ASU 2016-10, “Identifying Performance Obligations and Licensing” amends certain aspects of ASU 2014-09. ASU 2016-10 amends how an entity should identify performance obligations for immaterial promised goods or services, shipping and handling activities and promises that may represent performance obligations. ASU 2016-10 also provides implementation guidance for determining the nature of licensing and royalties arrangements. ASU 2016-12, “Narrow-Scope Improvements and Practical Expedients” also clarifies certain aspects of ASU 2014-09, including the assessment of collectability, presentation of sales taxes, treatment of noncash consideration and accounting for completed contracts and contract modifications at transition. ASU 2016-20, “Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers” allows an entity to determine the provision for loss contracts at either the contract level or the performance obligation level as an accounting policy election. The Company determines its provision for loss contracts at the contract level. The adoption of ASC 606 represents a change in accounting principle that aligns revenue recognition 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. To achieve this core principle, the Company applies the following five steps in accordance with ASC 606: (1) Identify the contract with a customer (2) Identify the performance obligations in the contract (3) Determine the transaction price (4) Allocate the transaction price to performance obligations in the contract (5) Recognize revenue as performance obligations are satisfied 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—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 previous guidance (i.e., percentage of completion). 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 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. Disaggregation of Revenues The Company’s revenues are principally derived from construction and engineering contracts related to Modules. Our contracts are with many different customers in numerous industries. The following tables provide further disaggregation of the Company’s revenues by categories:
|  |  | Twelve Months Ended December 31,
| Revenue by Customer Type |  | 2018 |  |  | 2017
| Multi-Family |  | $ | 344,968 |  |  | 4 | % |  |  | $ | — |  |  | — |
| Office |  |  | 2,221,431 |  |  | 27 | % |  |  |  | 1,384,967 |  |  | 28 | %
| Retail |  |  | 2,332,654 |  |  | 29 | % |  |  |  | 514,428 |  |  | 10 | %
| School |  |  | 2,697,451 |  |  | 33 | % |  |  |  | 3,122,035 |  |  | 62 | %
| Special Use |  |  | 559,755 |  |  | 7 | % |  |  |  | 22,838 |  |  | — |
| Other |  |  | 34,453 |  |  | — |  |  |  |  | 17,317 |  |  | — |
| Total revenue by customer type |  | $ | 8,190,712 |  |  | 100 | % |  |  | $ | 5,061,585 |  |  | 100 | %
Contract Assets and Contract Liabilities Accounts receivable are recognized in the period when the Company’s right to consideration is unconditional. Accounts receivable are recognized net of an allowance for doubtful accounts. A considerable amount of judgment is required in assessing the likelihood of realization of receivables. The timing of revenue recognition may differ from the timing of invoicing to customers. Contract assets include unbilled amounts from long-term construction services when revenue recognized under the cost-to-cost measure of progress exceeds the amounts invoiced to customers, as the amounts cannot be billed under the terms of our contracts. 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 assets are generally classified as current within the consolidated balance sheets and labeled as “costs and estimated earnings in excess of billings on uncompleted contracts”. Contract liabilities from construction and engineering contracts occur when amounts invoiced to customers exceed revenues recognized under the cost-to-cost measure of progress. 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. Contract liabilities are generally classified as current within the consolidated balance sheet and labeled as “billings in excess of costs and estimated earnings on uncompleted contracts”. Although the Company believes it has established adequate procedures for estimating costs to complete on open contracts, it is at least reasonably possible that additional significant costs could occur on contracts prior to completion. The Company periodically evaluates and revises its estimates and makes adjustments when they are considered necessary. Impact of the Adoption of ASC 606 on Financial Statements Prior to implementing ASC 606 on January 1, 2018, the Company’s methods for recognizing revenue were very similar to the current method under ASC 606. The actual cost as a percent of total expected cost at completion was used to estimate the percentage completed 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 modifications were required to be made to the Company's method of revenue recognition.
Cash and cash equivalents | Cash and cash equivalents – The Company considers cash and cash equivalents to include all short-term, highly liquid investments that are readily convertible to known amounts of cash and have original maturities of three months or less upon acquisition. Cash and cash equivalents totaled $1,368,395 and $4,870,824 for the years ended December 31, 2018 and 2017, respectively.
Short-term investment | Short-term investment – The Company classifies its investment consisting of a certificate of deposit with a maturity greater than three months but less than one year as short-term investment. The Company had no short-term investment as of December 31, 2018. The Company had $30,033 in short-term investment as of December 31, 2017.
Accounts receivable and Allowance for Doubtful Accounts | Accounts receivable and allowance for doubtful accounts – Accounts receivable are receivables generated from sales to customers and progress billings on performance type contracts. Amounts included in accounts receivable are deemed to be collectible within the Company’s operating cycle. The Company recognizes account receivable at invoiced amounts. The allowance for doubtful accounts reflects the Company's best estimate of probable losses inherent in the accounts receivable balances. Management provides an allowance for doubtful accounts based on the Company’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 our estimates and could be material to our consolidated financial position, result of operations, and cash flows.
Inventory | Inventory – Raw construction materials (primarily shipping containers) are valued at the lower of cost (first-in, first-out method) or net realizable value. Finished goods and work-in-process inventories are valued at the lower of cost or net realizable value, using the specific identification method. There was no inventory as of December 31, 2018 and 2017.
Goodwill | 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’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’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’s evaluation of goodwill completed during the year ended December 31, 2018 resulted in no impairment losses.
Intangible assets | Intangible assets – 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, included in intangible assets is $28,820 of trademarks and $5,300 of website costs which are being amortized over 5 years. The Company evaluated intangible assets for impairment during the year ended December 31, 2018, and determined that there are no impairment losses. The accumulated amortization and amortization expense as of and for the year ended December 31, 2018 was $1,469,191 and $589,619, respectively. The accumulated amortization and amortization expense as of and for the year ended December 31, 2017 was $879,573 and $587,823, respectively. The estimated amortization expense for the successive five years is as follows:
| For the year ending December 31,: |  |  |
| 2019 |  | $ | 145,124 |
| 2020 |  |  | 145,124 |
| 2021 |  |  | 145,124 |
| 2022 |  |  | 140,801 |
| 2023 |  |  | 139,006 |
| Thereafter |  |  | 1,728,750 |
|  |  | $ | 2,443,929 |
Equipment | Property, plant and equipment – Property, plant and equipment is stated at cost. Depreciation is computed using the straight-line method over the estimated lives of each asset. Estimated useful life for significant classes of assets are as follows: computer and software 3 to 5 years and equipment 5 to 7 years. Repairs and maintenance are charged to expense when incurred.
Convertible instruments | Convertible instruments – The Company bifurcates conversion options from their host instruments and accounts for them as free standing derivative financial instruments according to certain criteria. The criteria include circumstances in which (a) the economic characteristics and risks of the embedded derivative instrument are not clearly and closely related to the economic characteristics and risks of the host contract, (b) the hybrid instrument that embodies both the embedded derivative instrument and the host contract is not re-measured at fair value under otherwise applicable generally accepted accounting principles with changes in fair value reported in earnings as they occur and (c) a separate instrument with the same terms as the embedded derivative instrument would be considered a derivative instrument.
Common stock purchase warrants and other derivative financial instruments | Common stock purchase warrants and other derivative financial instruments – The Company classifies as equity any contracts that (i) require physical settlement or net-share settlement or (ii) provides a choice of net-cash settlement or settlement in the Company’s own shares (physical settlement or net-share settlement) providing that such contracts are indexed to the Company’s own stock. 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’s control) or (ii) gives the counterparty a choice of net-cash settlement or settlement shares (physical settlement or net-cash settlement). 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.
Fair value measurements | Fair value measurements – Financial instruments, including cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities are carried at cost, which the Company believes approximates fair value due to the short-term nature of these instruments. The Company measures the fair value of financial assets and liabilities based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. The Company uses three levels of inputs that may be used to measure fair value:
| Level 1 | Quoted prices in active markets for identical assets or liabilities.
| Level 2 | Quoted prices for similar assets and liabilities in active markets or inputs that are observable.
| Level 3 | Inputs that are unobservable (for example, cash flow modeling inputs based on assumptions).
Financial assets and liabilities measured at fair value on a recurring basis are summarized below: Short-term investment: The Company had $30,033 in a short-term investment as of December 31, 2017, which was classified within Level 2 of the valuation hierarchy. During the year ended December 31, 2018, the investment was redeemed, and the proceeds are included in the cash balance at December 31, 2018.
|  |  | December 31, 2017 |  |  | Quoted prices in active market for identical assets (Level l) |  |  | Significant other observable inputs (Level 2) |  |  | Significant unobservable inputs (Level 3) |
| Short-term investment |  | $ | 30,033 |  |  | $ | — |  |  | $ | 30,033 |  |  | $ | — |
Conversion option liabilities: Conversion option liabilities are measured at fair value using the Black-Scholes model and are classified within Level 3 of the valuation hierarchy. For fair value measurements categorized within Level 3 of the fair value hierarchy, the Company’s Chief Financial Officer, who reports to the Chief Executive Officer, determines the Company's valuation policies and procedures. The development and determination of the unobservable inputs for Level 3 fair value measurements and fair value calculations are the responsibility of the Company’s Chief Financial Officer and are approved by the Chief Executive Officer. The following table sets forth a summary of the changes in the fair value of the Company’s Level 3 financial liabilities that are measured at fair value on a recurring basis:
|  |  | For the year ended December 31, 2017 |
| Beginning balance |  | $ | 384,461 |
| Aggregate fair value of conversion option liabilities issued |  |  | — |
| Change in fair value related to conversion of convertible debentures |  |  | (288,134 | )
| Change in fair value of conversion option liabilities |  |  | (96,327 | )
| Ending balance |  | $ | — |
The Company presented conversion option liabilities at fair value on its consolidated balance sheets, with the corresponding changes in fair value recorded in the Company’s consolidated statements of operations for the applicable reporting periods. As disclosed in Note 7, the Company computed the fair value of the conversion option liabilities at the dates of issuance and the reporting dates of December 31, 2017, using a Black-Scholes model.
Share-based payments | Share-based payments – 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, 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 are 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.
Income taxes | Income taxes – 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’s assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. 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’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. 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. Impact of the Tax Cuts and Jobs Act The TCJA was enacted in the United States on December 22, 2017. Among other things, 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. The Securities and Exchange Commission issued Staff Accounting Bulletin No. 118, “Income Tax Accounting Implications of the Tax Cuts and Jobs Act” (“SAB 118”), to address the GAAP application of the TCJA. SAB 118 provided companies up to a year to finalize accounting for the impacts of the TCJA. The Company recognized the income tax effects of the TCJA in its consolidated financial statements for the year ended December 31, 2018. During the year ended December 31, 2018, the Company did not have any provisional tax expense for foreign withholding taxes associated with the TCJA.
Concentrations of credit risk | Concentrations of credit risk – Financial instruments, that potentially subject the Company to concentration of credit risk, consist principally of cash and cash equivalents. 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 such account and believes that it is not exposed to any significant credit risk on the account. With respect to receivables, concentrations of credit risk are limited to a few customers in the construction industry. The Company performs ongoing credit evaluations of its customers’ financial condition and, generally, requires no collateral from its customers other than normal lien rights. At December 31, 2018 and 2017, 76% and 81%, respectively, of the Company’s accounts receivable were due from two customers. Revenue relating to three and two customers represented approximately 66% and 80% of the Company’s total revenue for the years ended December 31, 2018 and 2017, respectively. Cost of revenue relating to two and one vendors represented approximately 55% of the Company’s total cost of revenue for the years ended December 31, 2018 and 2017, respectively. The Company believes it has access to alternative suppliers, with limited disruption to the business, should circumstances change with its existing suppliers.
