Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. (a) The consolidated financial statements include the financial statements of the Company and all of its subsidiaries. The Company consolidates companies in which it has controlling interest over 50%. All significant intercompany accounts, transactions and cash flows have been eliminated on consolidation. (b) Cash and cash equivalents include all cash balances and certificates of deposit having a maturity date of three months or less upon acquisition. As of December 31, 2019 and 2018, the Company had the cash and cash equivalents of $130,218 and $62,919, respectively. (c) All highly liquid investments with original maturities of greater than three months and less than 12 months are classified as short-term investments. Investments that are expected to be realized in cash during the next 12 months are also included in short-term investments. As 2019, the Company had investments that are expected to be realized in 2020 of $2,166 and for the year 2018, the balance of (d) Long term investments Long term investments include certificates of deposit having a maturity date at acquisition. A the Company had no (2018: $2,204). ( e ) Real estate properties under development, net are stated at the lower of carrying amounts or fair value less selling costs. In accordance with Accounting Standards Codification (“ASC”) 360, “Property, Plant and Equipment” All land in PRC is owned by the PRC government. The government in the PRC, according to PRC law, may sell the right to use the land for a specified period of time. Thus, the Company’s land purchased in Shenzhen PRC is considered to be leasehold land and is classified as real estate properties under development, net in the consolidated balance sheet. The buildings and land use rights included in real estate properties under development have not been depreciated since June 1, 2016. ( f ) Property, plant and equipment, net Property, plant and equipment are recorded at cost and include interest on funds borrowed to finance construction, if applicable. The cost of major improvements and betterments is capitalized whereas the cost of maintenance and repairs is expensed in the year incurred. Gains and losses from the disposal of property, plant and equipment and land use rights are included in the consolidated statement of comprehensive income (loss). The majority of the land in Hong Kong is owned by the government of Hong Kong, which leases the land at public auction to non-governmental entities. All of the Company’s leasehold lands in Hong Kong have leases of not more than 50 years from the respective balance sheet dates. The cost of such leasehold land is amortized on a straight-line basis over the respective terms of the leases. All land in other regions of the PRC is owned by the PRC government. The government in the PRC, according to PRC law, may sell the right to use the land for a specified period of time. Thus, the Company’s land purchases in Wuxi PRC are considered to be leasehold land and are classified as land use rights in the consolidated balance sheet. They are amortized on a straight-line basis over the respective term of the right to use the land. The Company computed depreciation expenses using the straight-line method over the following estimated useful lives: Classification Years Land use right 50 years Buildings 20 years – 50 years Machinery and equipment 4 years Leasehold improvements shorter of lease term or 4 years Furniture and fixtures 4 years Motor vehicle 4 years (g ) Long-lived assets other than goodwill are included in impairment evaluations when events and circumstances exist that indicate the carrying value of these assets may not be recoverable. In accordance with FASB ASC 360 “ Property, Plant and Equipment Long-lived assets to be disposed of are stated at the lower of fair value and carrying value. Expected future operating losses from discontinued operations are recorded in the periods in which the losses are incurred. In 2017, our management decided not to sell the long-lived assets in Wuxi that previously were classified as assets held for sale, thus the assets should be reclassified as property, plant, and equipment. According to FASB ASC 360-10-35-44 “a long-lived asset that is reclassified shall be measured individually at the lower of the following: a. Its carrying amount before the asset (disposal group) was classified as held for sale, adjusted for any depreciation (amortization) expense that would have been recognized had the asset (disposal group) been continuously classified as held and used, b. Its fair value at the date of the subsequent decision not to sell.” Therefore, the assets in Wuxi were reclassified to the account of property, plant, and equipment and recorded at the amount of $20,164. In 2017, the Company assessed the impairment of its long-lived assets used in Shenzhen and Wuxi by comparing external appraisals obtained from independent valuation firms with the carrying amounts of the assets. The results indicated the carrying amounts of the Company’s long-lived assets at December 31, 2017 were less than external appraisals obtained from independent valuation firms and no impairment loss was recognized in 2017. In 2018, the Company assessed the impairment of its long-lived assets used in Wuxi by comparing the undiscounted cash flows with the carrying amounts of the assets. The results indicated the undiscounted cash flows exceeded the carrying amounts of the Company’s long-lived assets at December 31, 2018 and no impairment loss was recognized in 2018. In 2018, the Company assessed the impairment of its long-lived assets used in Shenzhen by comparing external appraisals obtained from independent valuation firms with the carrying amounts of the assets. The results indicated the carrying amounts of the Company’s long-lived assets at December 31, 2018 were less than external appraisals obtained from independent valuation firms and no impairment loss was recognized in 2018. In 2019, the Company assessed the impairment of its long-lived assets used in Shenzhen and Wuxi by comparing undiscounted cash flows with the carrying amounts of the assets. The results indicated the carrying amounts of the Company’s long-lived assets at December 31, 2019 were less than undiscounted cash flows and no impairment loss was recognized in 2019. (h ) Accruals and provisions for loss contingencies The Company makes provisions for all material loss contingencies when information available prior to the issuance of the consolidated financial statements indicates that it is probable that an asset has been impaired or a liability has been incurred at the date of the consolidated financial statements and the amount of loss can be reasonably estimated. For provisions or accruals related to litigation, the Company makes provisions based on information from legal counsel and the best estimation of management. The Company assesses the potential liability for the significant legal proceedings in accordance with FASB ASC 450 “ Contingencies” (i ) The Company mainly generates revenue by operating the industrial parks and providing property management services. For lease income Lease income includes minimum rents which are recognized on an accrual basis over the terms of the related leases on a straight-line basis. Lease revenue recognition commences when the lessee is given possession of the leased space and there are no contingencies offsetting the lessee’s obligation to pay rent. For property service income According to FASB ASC 606 “Revenue form Contracts with Customers”, the realization of property service revenue can be recognized as the performance obligation is satisfied over time as services are rendered. (j ) The Company’s costs related to the staff retirement plans (see Note 11) are charged to the consolidated statement of comprehensive income as incurred. ( k) Advertising and promotion costs are expensed as incurred. For the year ended December 31, 2019, the Company recorded advertising and promotion expenses of $3,880 (2018: $331; 2017: nil). ( l ) Deferred income taxes are recorded for temporary differences between the tax basis of assets and liabilities and their reported amounts on the consolidated financial statements. A valuation allowance is established against deferred tax assets when it is more likely than not that some portion or all of the deferred tax assets will not be realized. FASB ASC 740 clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements and prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. It also provides accounting guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. Interest and penalties from tax assessments, if any, are included in income taxes in the consolidated statement of comprehensive income. ( m ) All transactions in currencies other than functional currencies during the year are translated at the exchange rates prevailing on the respective transaction dates. Monetary assets and liabilities existing at the balance sheet date denominated in currencies other than functional currencies are re-measured at the exchange rates on that date. Exchange differences are recorded in the consolidated statement of comprehensive income. The functional currencies of the Company and its subsidiaries include the Renminbi, U.S. dollar and the Hong Kong dollar. Effective from April 1, 2015, the Company’s subsidiaries in China changed their functional currency from the U.S. dollar to Renminbi. This change was made upon the progress of the property development projects in China causing the Company’s subsidiaries primary operating activities to be in Renminbi and making the Renminbi the currency of the economic environment in which the entities primarily generate and expend cash. The financial statements of all subsidiaries are translated in accordance with FASB ASC 830 “ Foreign Currency Matters The financial statements and other financial data of the Company included in this annual report are presented in U.S. dollars. The business and operations of the Company are primarily conducted in China through its PRC subsidiaries. The functional currency of its PRC subsidiaries is Renminbi. The financial statements of its PRC subsidiaries are translated into U.S. dollars, using published exchange rates from banks in China, based on (i) year-end exchange rates or the rates of exchange ruling at the balance sheet date for assets and liabilities and (ii) average yearly exchange rates for income and expense items. Capital accounts are translated at historical exchange rates when the transactions occurred. The effects of foreign currency translation adjustments are included as a component of accumulated other comprehensive income (loss) in shareholders’ equity. The Company makes no representation that any Renminbi or U.S. dollar amounts could have been, or could be, converted into U.S. dollar or Renminbi, as the case may be, at any particular rate or at all. ( n ) Basic earnings per share is computed by dividing net income attributable to common shareholders by the weighted average number of common shares outstanding during the year. Diluted earnings per share gives effect to all dilutive potential common shares outstanding during the year. The weighted average number of common shares outstanding is adjusted to include the number of additional common shares that would have been outstanding if the dilutive potential common shares had been issued. ( o ) The Company has two stock-based employee compensation plans, as more fully described in Note 9(b). The Company measures the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. That cost is recognized over the period during which an employee is required to provide service, the requisite service period (usually the vesting period), in exchange for the award. The grant-date fair value of employee share options and similar instruments are estimated using option-pricing models. If the award is modified after the grant date, incremental compensation cost is recognized in an amount equal to the excess of the fair value of the modified award over the fair value of the original award immediately before the modification. ( p ) The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America 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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include valuation allowance for deferred income tax assets, stock-based compensation, useful lives of property, plant and equipment and impairment of long-lived assets. In accordance with its policy, the Company reviews the estimated useful lives of its fixed assets on an ongoing basis. This review indicated that the useful lives of certain buildings at Wuxi factory were longer than the previous estimated useful lives due to the change of function of these buildings. As a result, effective from February 1, 2019, the Company changed its estimates of the useful lives of these buildings in Wuxi to better reflect the estimated periods during which these assets will remain in service. The estimated useful lives of the buildings that previously averaged 20 years were increased to an average of 47 years. The effect of this change in estimate reduced 2019 depreciation expense by $674. ( q ) Accumulated other comprehensive income (loss) represents principally foreign currency translation adjustments and is included in the consolidated statement of changes in shareholders’ equity. ( r ) The Company follows FASB ASC 820 “ Fair Value Measurements and Disclosures Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement: Level 1 — Quoted prices in active markets for identical assets or liabilities that the reporting entity can access at the measurement date. Level 2 — Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 — Inputs that are generally unobservable and typically reflect management’s estimate of assumptions that market participants would use in pricing the asset or liability. The carrying amounts of cash and cash equivalents, short term investments, accounts and other receivables, accrued expenses and other payables, accounts payable, and short term bank loans approximate their fair values due to the short term nature of these instruments. As of December 31, 2017, 2018 and 2019, the Company did not have any non-financial assets and liabilities that are recognized or disclosed at fair value in the consolidated financial statements, at least annually, on a recurring basis. ( s ) According to FASB ASC 842 “Lease”, lessees are required to record a right of use asset and lease liabilities for all leases other than those have a lease term of 12 months or less, or the amount is under the reasonable capitalization threshold established by the Company. At the lease commencement date, a lessee should measure and record the lease liability equals to the present value of scheduled lease payments discounted using the rate implicit in the lease or the leasee’s incremental borrowing rate, and the right of use asset is calculated on the basis of the initial measurement of the lease liability, plus any lease payments at or before the commencement date and direct costs, minus any incentives received. Over the lease term, a lessee must amortize the right of use asset and record the interest expense on the lease liability. The recognition and classification of lease expenses depend on the classification of the lease as either operating or finance. When the Company is the lessor, minimum contractual rental from leases is recognized on a straight-line basis over the non-cancelable term of the lease. With respect to a particular lease, actual amounts billed in accordance with the lease during any given period may be higher or lower than the amount of rental revenue recognized for the period. Straight-line rental revenue commences when the customer assumes control of the leased premises. Accrued straight-line rents receivable represents the amount by which straight-line rental revenue exceeds rents currently billed in accordance with lease agreements. If later, the billing amount exceeds the straight-line rental revenue, the variance will be credited to accrued straight-line rents receivable. Contingent rental revenue is accrued when the contingency is removed. ( t ) The Company’s potential significant concentration of credit risk primarily consists of cash and cash equivalents, short term investments and long term investments which are held by financial institutions in and outside of the PRC. As of December 31, 2019, the Company has $96,865 in cash and cash equivalents which are held by financial institutions in the PRC. PRC state-owned banks are subject to a series of risk control regulatory standards, and PRC bank regulatory authorities are empowered to take over the operation and management when any of those faces a material credit crisis. The Company does not foresee substantial credit risk with respect to cash and cash equivalents and short term investments held at the PRC state-owned banks. Based on the order of the State Council of the PRC (No.660): Deposit Insurance Regulation effective on May 1, 2015, the maximum amount of coverage is $76 (RMB 0.5 million) for deposits and foreign currency deposits in the same financial institutions. In the event of bankruptcy of one of the financial institutions in which the Company has deposits, deposits in excess of $76 (RMB 0.5 million) shall be compensated from liquidation of the financial institution. As of December 31, 2019, total of $1,327 was covered by the Deposit Insurance Regulation. Overall, the real estate market in China has shown signs of a continuous slow-down. The Company’s results of operations Accordingly, the Company’s business, financial condition and results of operations are primarily influenced by the political, economic, legal environments and foreign currency exchange in the PRC and by the general state of the PRC economy and may be adversely affected by changes in social conditions in the PRC, and by changes in governmental policies with respect to laws and regulations, anti-inflationary measures, currency conversion and remittance abroad, and rates and methods of taxation. As a result, the Company may experience significant fluctuations in future operating results due to the factors mentioned above. These fluctuations may result in volatility in the share price of the Company. All the Company’s land development related applications are subject to government policies and regulations in the real estate market. However, the Company cannot provide assurance that it will obtain all the necessary approvals in accordance with its timetable. Furthermore, as this is the Company’s first venture into land development projects after the cessation of the LCM business, and the Company may encounter industry-specific difficulties that result in losses as it progresses with its development and projects in Shenzhen. The Company currently derives a majority of its income from rental and interest income. Any future reductions in the official cash deposit interest rates in China and Hong Kong could adversely impact its income and the total cash on hand will gradually decrease as more funds are being used for land development related expenditures for the land in Gushu and Guangming, Shenzhen. Certain transactions of the Company are denominated in Renminbi, which is not freely convertible into foreign currencies. All foreign exchange transactions take place either through the Peoples Bank of China (“PBOC”) or other banks authorized to buy and sell foreign currencies at the exchange rates quoted by the PBOC. Approval of foreign currency payments by the PBOC or other institutions requires submitting a payment application form together with suppliers’ invoices, shipping documents and signed contracts. ( u ) In February 2016, the FASB issued ASU 2016-02, Lease (Subtopic 842) with subsequent amendments made via ASU 2018-01, ASU 2018-10, ASU 2018-11, ASU 2018-20 and ASU 2019-01. These updates established ASC 842, “Leases”, with the aim to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The new lease standard was effective for us on January 1, 2019. Under ASC 842, The Company classifies leases as either finance leases (formerly capital leases) or operating leases, and a right-of-use asset and lease liability are required to be recognized in the consolidated balance sheets for both finance and operating leases with a term longer than 12 months. The new lease standard required a modified retrospective transition approach and provides an optional transition method to either (1) record current existing leases as of the effective date; or (2) record leases existing as of the earliest comparative period presented in the financial statements by recasting comparative period financial statements. The Company adopted the new lease standard as of January 1, 2019 using the effective date as our date of application. As such, financial statement information and disclosures required under the new lease standard are not provided for dates and periods prior to January 1, 2019. The new lease standard provides for a number of optional practical expedients in transition, which include: (1) not requiring an entity to reassess prior conclusions about lease identification, lease classification or initial direct costs; (2) allowing an entity to use a portfolio approach for similar lease assets; (3) allowing an entity to elect an accounting policy to choose not to separate non-lease components of an agreement from lease components (by asset class); (4) allowing the use of hindsight in estimating lease term or assessing impairment of right-of-use assets; and (5) not requiring an entity to reassess prior conclusions about land easements. The Company elected all of the practical expedients permitted under the transition guidance within the new lease standard. The new lease standard also provides practical expedients for ongoing accounting. The Company elected the short-term lease recognition exemption for our real estate and equipment leases, which means that for those leases that qualify, the Company does not recognize right-of-use assets or lease liabilities and recognize the expense related to the short-term leases on a straight-line basis over the lease term and any variable lease payments in the period in which the obligation for those payments is incurred. It has also elected the practical expedient that allows us not to separate non-lease components of an agreement from lease components (for certain non-real estate assets). See Note 15 for further discussion. In June 2016, the FASB issued ASU No. 2016-13 Financial Instruments—Credit Losses (Topic 326): Measurements of Credit Losses on Financial Instruments. This Update replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. This Update will be effective for public business entities that are US SEC filers for fiscal years beginning after December 15, 2019. The adoption of ASU 2016-13 is not expected to have a material impact on the consolidated financial statements in 2020. In June 2018, the FASB issued ASU No. 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting. As a result of the Update, the accounting for share-based compensation for employees and non-employees is substantially aligned. For public business entities, this Update is for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. The adoption of ASU 2018-07 did not have a material impact on the Company’s consolidated financial statements in 2019. In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740)-Simplifying the Accounting for Income Taxes. This update simplifies the accounting for income taxes with measures, among others, including: (1) removing exception to incremental approach for intra-period tax allocation when there is a loss from continuing operations and income or a gain from other items; and (2) specifying that an entity is not required to allocate the consolidated amount of current and deferred tax expense to a legal entity that is not subject to tax in its separate financial statements. However, an entity may elect to do so (on an entity-by-entity basis) for a legal entity that is both not subject to tax and disregarded by the taxing authority. This Update will be effective for public business entities that are US SEC filers for fiscal years beginning after December 15, 2020. The adoption of ASU 2019-12 is not expected to have a material impact on the Company’s consolidated financial statements in 2020.

Retained Earnings and Reserves	6 . The Company’s retained earnings are not restricted as to the payment of dividends except to the extent dictated by prudent business practices. The Company believes that there are no material restrictions, including foreign exchange controls, on the ability of its non-PRC subsidiaries to transfer surplus funds to the Company in the form of cash dividends, loans, advances or purchases. With respect to the Company’s PRC subsidiaries, there are restrictions on the payment of dividends and the distribution of dividends from the PRC. On March 16, 2007, the PRC promulgated the Law of the PRC on Enterprise Income Tax (the “New Law”) by Order No. 63 of the President of the PRC. The New Law was effective on January 1, 2008. Please refer to Note 13 for further details of the New Law. Prior to the enactment of the New Law, when dividends were paid by the Company’s PRC subsidiaries, such dividends would reduce the amount of reinvested profits and accordingly, the refund of taxes paid might be reduced to the extent of tax applicable to profits not reinvested. Subsequent to the enactment of the New Law, due to the removal of the tax benefit related to reinvestment of capital in PRC subsidiaries, the Company may not reinvest the profits made by its PRC subsidiaries. In addition, pursuant to the relevant PRC regulations, a certain portion of the profits made by these subsidiaries must be set aside for future capital investment and are not distributable, and the registered capital of the Company’s PRC subsidiaries is also restricted. These reserves and registered capital of the PRC subsidiaries amounted to $376,641 and $376,449 as of December 31, 2018 and 2019, respectively. However, the Company believes that such restrictions will not have a material effect on the Company’s liquidity or cash flows.

Income Tax Disclosure [Abstract]
Income Taxes	13 . The components of income (loss) before income tax are as follows: Year ended December 31, 2017 2018 2019 PRC, excluding Hong Kong $ (6,759 ) $ (10,590 ) $ (10,404 ) Hong Kong and other jurisdictions 10,703 (2,664 ) (4,827 ) $ 3,944 $ (13,254 ) $ (15,231 ) The Company’s income is not subject to taxation in BVI under the current BVI law. Subsidiaries operating in Hong Kong and the PRC are subject to income taxes as described below. Under the current BVI law, NTHL is not subject to profits tax in the BVI. However, it may be subject to Hong Kong income taxes as described below if it has income earned in or derived from Hong Kong. The provision for current income taxes of the subsidiaries operating in Hong Kong has been calculated by applying the rate of taxation of 16.5% for the years ended December 31, 2017, 2018 and 2019 to the estimated income earned in or derived from Hong Kong during the respective years, if applicable. The provision for current income taxes of the subsidiaries operating in PRC has been calculated by applying the rate of taxation of 25% for the years ended December 31, 2017, 2018 and 2019. The Company, which has subsidiaries that are tax resident in the PRC, is subject to the PRC dividend withholding tax of 5%, when and if undistributed earnings are declared to be paid as dividends to the extent those dividends are paid out of profits that arose on or after January 1, 2008. For the years ended December 31, 2017, 2018 and 2019, there was no income tax expense for the 5% dividend withholding tax on the balance of distributable earnings that arose on or after January 1, 2008 within its PRC subsidiaries. In line with management’s decision to change the core business, management decided to retain the undistributed earnings in the PRC. Uncertainties exist with respect to how the PRC’s current income tax law applies to the Company’s overall operations, and more specifically, with regard to tax residency status. The New Law includes a provision specifying that legal entities organized outside of the PRC will be considered as resident enterprises for PRC enterprises income tax purpose if their active management is located in the PRC. The Implementation Rules to the New Law provide that non-resident legal entities will be considered PRC residents enterprises if substantial and overall management control over the manufacture, operations, personnel, accounting, properties, etc. occurs within the PRC. The Company has made its assessment of each tax position (including the potential application of interest and penalties) based on the available tax laws, and has measured the unrecognized tax benefits associated with the tax positions. Based on the evaluation by the Company, it is concluded that there are no significant uncertain tax positions requiring recognition in the consolidated financial statements. The Company classifies interest and/or penalties related to unrecognized tax benefits as a component of income tax provisions. However, during the years ended December 31, 2017, 2018 and 2019, there were no interest and penalties related to uncertain tax positions and the Company had no material unrecognized tax benefit which would favorably affect the effective income tax rate in future periods. The Company does not anticipate any significant increases or decreases to its liability for unrecognized tax benefit within the next twelve months. Other than the audit by the Hong Kong tax authorities as described below, the tax positions for the years 2017 to 2019 may be subject to examination by the PRC and Hong Kong tax authorities. Tax Disputes with Hong Kong Inland Revenue Department. Since the fourth quarter of 2007, several of our inactive subsidiaries have been involved in tax disputes relating to tax years 1996 and later years with the Inland Revenue Department of Hong Kong, (the “HKIRD”), the income tax authority of the Hong Kong Government. These inactive subsidiaries include three Hong Kong entities, NTGM, NTTC and NTT. The disputes concern the appropriateness of expensing certain intra-group service fees under the transfer pricing context. NTGM is the parent company of NTT and NTTC. NTTC is the title holder of certain land in Hong Kong and is being liquidated. The particulars of these disputes are discussed below. NTTC Starting from October 2007, the HKIRD issued assessments and writs against NTTC claiming taxes and interests on unpaid taxes for the taxable years 1996/1997 to 2003/2004, for matters related to intra-group service fees. Judgments were entered against NTTC and on June 4, 2012 a winding-up order was issued by the High Court of Hong Kong against NTTC. The total tax claims against NTTC are $6.6 million plus interest. NTTC is currently in liquidation and the Joint and Several Liquidators confirmed that all assets of NTTC have been taken over by the Joint and Several Receivers in January 2013. As the Company did not have a controlling financial interest on NTTC after it was taken over by the Joint and Several Receivers, so the financial statements of NTTC have not been included in the consolidated financial statements of the Company subsequent to the 2012 Form-20F, in accordance with the procedures set out in ASC 810-10-15-10. NTT The HKIRD issued assessments and writs against NTT for matters related to intra-group service fees in taxable years 2002/2003. During the years 2009 and 2011, two judgments were entered against NTT, a dormant subsidiary. The total tax claims against NTT are $0.4 million plus interest. NTT had a net deficit position as of December 31, 2019 and the Company has no funding obligation towards NTT. As a result, the liability from the HKIRD demand letter has no impact on the Company. Therefore, the amount claimed by HKIRD was not recorded as a liability in the Company’s consolidated financial statements as of December 31, 2019. NTGM The HKIRD had issued assessments and writs against NTGM for matters related to intra-group service fee. During the years 2009 to 2011, two judgments were also entered against NTGM, a subsidiary that had been inactive since 2005. Since then, NTGM has received a number of demand letters from the HKIRD, demanding total payments of judgment debts for an aggregate amount of $1.1 million plus interest. On April 27, 2018, HKIRD issued a writ for issued assessments and writs against NTGM claiming taxes of $3,000 and interests on unpaid taxes for the taxable years 2001/2002. On August 15, 2018, judgment by consent was entered against NTGM for the amount with costs and interests. On November 1, 2018, NTGM received demanding for payment from HKIRD and notice to initiate wind-up procedures if payment not received by HKIRD within 14 days. NTGM received a demand for payment from HKIRD again on January 8, 2019 with no further demand payment received since then. NTGM has a net deficit position as of December 31, 2019 and we have no funding obligation towards NTGM. As a result, the claims from the HKIRD demand letters have no impact on the Company and the amount claimed by HKIRD on NTGM was not recorded as a liability in our consolidated financial statements as of December 31, 2019. Notices of Alleged Personal Liability for Additional Taxes against Former Directors and Officers for Signing NTTC’s Tax Returns The HKIRD had separately commenced legal proceedings against two former directors and officers of NTTC personally for taxable years 1996/1997, 1997/1998 and 1999/2000, in the total amount of approximately $2.3 million for additional tax by way of penalty for signing the tax returns of the Hong Kong subsidiaries in relation to the disputed intra-group service fees. Both directors have been indemnified under the Company’s indemnity policy. The Hong Kong Court of First Instance held a two-day hearing on April 18-19, 2018. On November 23, 2018, the Hong Kong Court of First Instance handed down a reasoned ruling, finding in favor of our two former directors on the main points of the appeal. On January 3, 2019, Hong Kong Court of First Instance also issued a court order annulling the assessment of personal liability against the two former directors. The HKIRD filed an appeal on December 21, 2018. The hearing of appeal was held in October 2019. The Hong Kong Court of Appeal has not handed down its reason for adjustment, but it is found in favor of two former directors at the end of hearing. The Company’s deferred tax assets as of December 31, 2018 and 2019 are attributable to the following: December 31, 2018 2019 Net operating losses $ 9,165 $ 10,490 Property, plant and equipment 142 (42 ) Total deferred tax assets 9,307 10,448 Less: valuation allowance (9,307 ) (8,437 ) Net deferred tax assets $ — $ 2,011 Movement of valuation allowance: December 31, 2017 2018 2019 At beginning of the year $ 5,315 $ 7,058 $ 9,307 Current year addition (deduction) 1,743 2,249 (870 ) At end of the year $ 7,058 $ 9,307 $ 8,437 The valuation allowance as of each of December 31, 2018 and 2019 was related to deferred tax assets generated by net operating losses carried forward and property, plant and equipment that, in the judgment of management, more likely than not will not be realized. In assessing the reliability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The ultimate realization of deferred tax assets depends on the generation of future taxable income in which those temporary differences and carry forwards become deductible. As of December 31, 2019 the Company had net operating losses of $3,321, which may be carried forward indefinitely. As of December 31, 2019, the Company had net operating losses of $6,613, $3,059, $8,731, $9,827, and $11,369, which will expire in the years ending December 31, 2020, 2021, 2022, 2023 and 2024, respectively. A reconciliation of the income tax expense to the amount computed by applying the current statutory tax rate to the income (loss) before income taxes in the consolidated statements of comprehensive income (loss) is as follows: Year ended December 31, 2017 2018 2019 Income (loss) before income taxes $ 3,944 $ (13,254 ) $ (15,231 ) PRC tax rate 25 % 25 % 25 % (Tax expense) tax benefit at PRC tax rate on income before income tax $ (986 ) $ 3,314 $ 3,808 Effect of difference between Hong Kong and PRC tax rates applied to Hong Kong income (208 ) (530 ) (192 ) Change in valuation allowance (1,743 ) (2,249 ) 870 Reversal of tax loss cannot be recoverable in future (950 ) — — Tax benefit (tax expense) arising from items which are not assessable (deductible) for tax purposes: Non-deductible and non-taxable items 3,118 94 (2,311 ) Loss from discontinued operations and others 769 (629 ) (135 ) Income tax benefit $ — $ — $ 2,040 No income tax arose in the United States of America in any of the periods presented.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2019
Accounting Policies [Abstract]
Principles of consolidation	(a) The consolidated financial statements include the financial statements of the Company and all of its subsidiaries. The Company consolidates companies in which it has controlling interest over 50%. All significant intercompany accounts, transactions and cash flows have been eliminated on consolidation.
Cash and cash equivalents	(b) Cash and cash equivalents include all cash balances and certificates of deposit having a maturity date of three months or less upon acquisition. As of December 31, 2019 and 2018, the Company had the cash and cash equivalents of $130,218 and $62,919, respectively.
Short-term investments	(c) All highly liquid investments with original maturities of greater than three months and less than 12 months are classified as short-term investments. Investments that are expected to be realized in cash during the next 12 months are also included in short-term investments. As 2019, the Company had investments that are expected to be realized in 2020 of $2,166 and for the year 2018, the balance of
Long term investments	(d) Long term investments Long term investments include certificates of deposit having a maturity date at acquisition. A the Company had no (2018: $2,204).
Real estate properties under development, net	( e ) Real estate properties under development, net are stated at the lower of carrying amounts or fair value less selling costs. In accordance with Accounting Standards Codification (“ASC”) 360, “Property, Plant and Equipment” All land in PRC is owned by the PRC government. The government in the PRC, according to PRC law, may sell the right to use the land for a specified period of time. Thus, the Company’s land purchased in Shenzhen PRC is considered to be leasehold land and is classified as real estate properties under development, net in the consolidated balance sheet. The buildings and land use rights included in real estate properties under development have not been depreciated since June 1, 2016.
Property, plant and equipment, net	( f ) Property, plant and equipment, net Property, plant and equipment are recorded at cost and include interest on funds borrowed to finance construction, if applicable. The cost of major improvements and betterments is capitalized whereas the cost of maintenance and repairs is expensed in the year incurred. Gains and losses from the disposal of property, plant and equipment and land use rights are included in the consolidated statement of comprehensive income (loss). The majority of the land in Hong Kong is owned by the government of Hong Kong, which leases the land at public auction to non-governmental entities. All of the Company’s leasehold lands in Hong Kong have leases of not more than 50 years from the respective balance sheet dates. The cost of such leasehold land is amortized on a straight-line basis over the respective terms of the leases. All land in other regions of the PRC is owned by the PRC government. The government in the PRC, according to PRC law, may sell the right to use the land for a specified period of time. Thus, the Company’s land purchases in Wuxi PRC are considered to be leasehold land and are classified as land use rights in the consolidated balance sheet. They are amortized on a straight-line basis over the respective term of the right to use the land. The Company computed depreciation expenses using the straight-line method over the following estimated useful lives: Classification Years Land use right 50 years Buildings 20 years – 50 years Machinery and equipment 4 years Leasehold improvements shorter of lease term or 4 years Furniture and fixtures 4 years Motor vehicle 4 years
Impairment or disposal of long-lived assets	(g ) Long-lived assets other than goodwill are included in impairment evaluations when events and circumstances exist that indicate the carrying value of these assets may not be recoverable. In accordance with FASB ASC 360 “ Property, Plant and Equipment Long-lived assets to be disposed of are stated at the lower of fair value and carrying value. Expected future operating losses from discontinued operations are recorded in the periods in which the losses are incurred. In 2017, our management decided not to sell the long-lived assets in Wuxi that previously were classified as assets held for sale, thus the assets should be reclassified as property, plant, and equipment. According to FASB ASC 360-10-35-44 “a long-lived asset that is reclassified shall be measured individually at the lower of the following: a. Its carrying amount before the asset (disposal group) was classified as held for sale, adjusted for any depreciation (amortization) expense that would have been recognized had the asset (disposal group) been continuously classified as held and used, b. Its fair value at the date of the subsequent decision not to sell.” Therefore, the assets in Wuxi were reclassified to the account of property, plant, and equipment and recorded at the amount of $20,164. In 2017, the Company assessed the impairment of its long-lived assets used in Shenzhen and Wuxi by comparing external appraisals obtained from independent valuation firms with the carrying amounts of the assets. The results indicated the carrying amounts of the Company’s long-lived assets at December 31, 2017 were less than external appraisals obtained from independent valuation firms and no impairment loss was recognized in 2017. In 2018, the Company assessed the impairment of its long-lived assets used in Wuxi by comparing the undiscounted cash flows with the carrying amounts of the assets. The results indicated the undiscounted cash flows exceeded the carrying amounts of the Company’s long-lived assets at December 31, 2018 and no impairment loss was recognized in 2018. In 2018, the Company assessed the impairment of its long-lived assets used in Shenzhen by comparing external appraisals obtained from independent valuation firms with the carrying amounts of the assets. The results indicated the carrying amounts of the Company’s long-lived assets at December 31, 2018 were less than external appraisals obtained from independent valuation firms and no impairment loss was recognized in 2018. In 2019, the Company assessed the impairment of its long-lived assets used in Shenzhen and Wuxi by comparing undiscounted cash flows with the carrying amounts of the assets. The results indicated the carrying amounts of the Company’s long-lived assets at December 31, 2019 were less than undiscounted cash flows and no impairment loss was recognized in 2019.
Accruals and provisions for loss contingencies	(h ) Accruals and provisions for loss contingencies The Company makes provisions for all material loss contingencies when information available prior to the issuance of the consolidated financial statements indicates that it is probable that an asset has been impaired or a liability has been incurred at the date of the consolidated financial statements and the amount of loss can be reasonably estimated. For provisions or accruals related to litigation, the Company makes provisions based on information from legal counsel and the best estimation of management. The Company assesses the potential liability for the significant legal proceedings in accordance with FASB ASC 450 “ Contingencies”
Revenue recognition	(i ) The Company mainly generates revenue by operating the industrial parks and providing property management services. For lease income Lease income includes minimum rents which are recognized on an accrual basis over the terms of the related leases on a straight-line basis. Lease revenue recognition commences when the lessee is given possession of the leased space and there are no contingencies offsetting the lessee’s obligation to pay rent. For property service income According to FASB ASC 606 “Revenue form Contracts with Customers”, the realization of property service revenue can be recognized as the performance obligation is satisfied over time as services are rendered.
Staff retirement plan costs	(j ) The Company’s costs related to the staff retirement plans (see Note 11) are charged to the consolidated statement of comprehensive income as incurred.
Advertising and promotion costs	( k) Advertising and promotion costs are expensed as incurred. For the year ended December 31, 2019, the Company recorded advertising and promotion expenses of $3,880 (2018: $331; 2017: nil).
Income taxes	( l ) Deferred income taxes are recorded for temporary differences between the tax basis of assets and liabilities and their reported amounts on the consolidated financial statements. A valuation allowance is established against deferred tax assets when it is more likely than not that some portion or all of the deferred tax assets will not be realized. FASB ASC 740 clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements and prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. It also provides accounting guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. Interest and penalties from tax assessments, if any, are included in income taxes in the consolidated statement of comprehensive income.
Foreign currency transactions and translations	( m ) All transactions in currencies other than functional currencies during the year are translated at the exchange rates prevailing on the respective transaction dates. Monetary assets and liabilities existing at the balance sheet date denominated in currencies other than functional currencies are re-measured at the exchange rates on that date. Exchange differences are recorded in the consolidated statement of comprehensive income. The functional currencies of the Company and its subsidiaries include the Renminbi, U.S. dollar and the Hong Kong dollar. Effective from April 1, 2015, the Company’s subsidiaries in China changed their functional currency from the U.S. dollar to Renminbi. This change was made upon the progress of the property development projects in China causing the Company’s subsidiaries primary operating activities to be in Renminbi and making the Renminbi the currency of the economic environment in which the entities primarily generate and expend cash. The financial statements of all subsidiaries are translated in accordance with FASB ASC 830 “ Foreign Currency Matters The financial statements and other financial data of the Company included in this annual report are presented in U.S. dollars. The business and operations of the Company are primarily conducted in China through its PRC subsidiaries. The functional currency of its PRC subsidiaries is Renminbi. The financial statements of its PRC subsidiaries are translated into U.S. dollars, using published exchange rates from banks in China, based on (i) year-end exchange rates or the rates of exchange ruling at the balance sheet date for assets and liabilities and (ii) average yearly exchange rates for income and expense items. Capital accounts are translated at historical exchange rates when the transactions occurred. The effects of foreign currency translation adjustments are included as a component of accumulated other comprehensive income (loss) in shareholders’ equity. The Company makes no representation that any Renminbi or U.S. dollar amounts could have been, or could be, converted into U.S. dollar or Renminbi, as the case may be, at any particular rate or at all.
Earnings per share	( n ) Basic earnings per share is computed by dividing net income attributable to common shareholders by the weighted average number of common shares outstanding during the year. Diluted earnings per share gives effect to all dilutive potential common shares outstanding during the year. The weighted average number of common shares outstanding is adjusted to include the number of additional common shares that would have been outstanding if the dilutive potential common shares had been issued.
Stock options	( o ) The Company has two stock-based employee compensation plans, as more fully described in Note 9(b). The Company measures the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. That cost is recognized over the period during which an employee is required to provide service, the requisite service period (usually the vesting period), in exchange for the award. The grant-date fair value of employee share options and similar instruments are estimated using option-pricing models. If the award is modified after the grant date, incremental compensation cost is recognized in an amount equal to the excess of the fair value of the modified award over the fair value of the original award immediately before the modification.
Use of estimates	( p ) The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America 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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include valuation allowance for deferred income tax assets, stock-based compensation, useful lives of property, plant and equipment and impairment of long-lived assets. In accordance with its policy, the Company reviews the estimated useful lives of its fixed assets on an ongoing basis. This review indicated that the useful lives of certain buildings at Wuxi factory were longer than the previous estimated useful lives due to the change of function of these buildings. As a result, effective from February 1, 2019, the Company changed its estimates of the useful lives of these buildings in Wuxi to better reflect the estimated periods during which these assets will remain in service. The estimated useful lives of the buildings that previously averaged 20 years were increased to an average of 47 years. The effect of this change in estimate reduced 2019 depreciation expense by $674.
Comprehensive income (loss)	( q ) Accumulated other comprehensive income (loss) represents principally foreign currency translation adjustments and is included in the consolidated statement of changes in shareholders’ equity.
Fair value measurements	( r ) The Company follows FASB ASC 820 “ Fair Value Measurements and Disclosures Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement: Level 1 — Quoted prices in active markets for identical assets or liabilities that the reporting entity can access at the measurement date. Level 2 — Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 — Inputs that are generally unobservable and typically reflect management’s estimate of assumptions that market participants would use in pricing the asset or liability. The carrying amounts of cash and cash equivalents, short term investments, accounts and other receivables, accrued expenses and other payables, accounts payable, and short term bank loans approximate their fair values due to the short term nature of these instruments. As of December 31, 2017, 2018 and 2019, the Company did not have any non-financial assets and liabilities that are recognized or disclosed at fair value in the consolidated financial statements, at least annually, on a recurring basis.
Leases	( s ) According to FASB ASC 842 “Lease”, lessees are required to record a right of use asset and lease liabilities for all leases other than those have a lease term of 12 months or less, or the amount is under the reasonable capitalization threshold established by the Company. At the lease commencement date, a lessee should measure and record the lease liability equals to the present value of scheduled lease payments discounted using the rate implicit in the lease or the leasee’s incremental borrowing rate, and the right of use asset is calculated on the basis of the initial measurement of the lease liability, plus any lease payments at or before the commencement date and direct costs, minus any incentives received. Over the lease term, a lessee must amortize the right of use asset and record the interest expense on the lease liability. The recognition and classification of lease expenses depend on the classification of the lease as either operating or finance. When the Company is the lessor, minimum contractual rental from leases is recognized on a straight-line basis over the non-cancelable term of the lease. With respect to a particular lease, actual amounts billed in accordance with the lease during any given period may be higher or lower than the amount of rental revenue recognized for the period. Straight-line rental revenue commences when the customer assumes control of the leased premises. Accrued straight-line rents receivable represents the amount by which straight-line rental revenue exceeds rents currently billed in accordance with lease agreements. If later, the billing amount exceeds the straight-line rental revenue, the variance will be credited to accrued straight-line rents receivable. Contingent rental revenue is accrued when the contingency is removed.
Concentration of risk	( t ) The Company’s potential significant concentration of credit risk primarily consists of cash and cash equivalents, short term investments and long term investments which are held by financial institutions in and outside of the PRC. As of December 31, 2019, the Company has $96,865 in cash and cash equivalents which are held by financial institutions in the PRC. PRC state-owned banks are subject to a series of risk control regulatory standards, and PRC bank regulatory authorities are empowered to take over the operation and management when any of those faces a material credit crisis. The Company does not foresee substantial credit risk with respect to cash and cash equivalents and short term investments held at the PRC state-owned banks. Based on the order of the State Council of the PRC (No.660): Deposit Insurance Regulation effective on May 1, 2015, the maximum amount of coverage is $76 (RMB 0.5 million) for deposits and foreign currency deposits in the same financial institutions. In the event of bankruptcy of one of the financial institutions in which the Company has deposits, deposits in excess of $76 (RMB 0.5 million) shall be compensated from liquidation of the financial institution. As of December 31, 2019, total of $1,327 was covered by the Deposit Insurance Regulation. Overall, the real estate market in China has shown signs of a continuous slow-down. The Company’s results of operations Accordingly, the Company’s business, financial condition and results of operations are primarily influenced by the political, economic, legal environments and foreign currency exchange in the PRC and by the general state of the PRC economy and may be adversely affected by changes in social conditions in the PRC, and by changes in governmental policies with respect to laws and regulations, anti-inflationary measures, currency conversion and remittance abroad, and rates and methods of taxation. As a result, the Company may experience significant fluctuations in future operating results due to the factors mentioned above. These fluctuations may result in volatility in the share price of the Company. All the Company’s land development related applications are subject to government policies and regulations in the real estate market. However, the Company cannot provide assurance that it will obtain all the necessary approvals in accordance with its timetable. Furthermore, as this is the Company’s first venture into land development projects after the cessation of the LCM business, and the Company may encounter industry-specific difficulties that result in losses as it progresses with its development and projects in Shenzhen. The Company currently derives a majority of its income from rental and interest income. Any future reductions in the official cash deposit interest rates in China and Hong Kong could adversely impact its income and the total cash on hand will gradually decrease as more funds are being used for land development related expenditures for the land in Gushu and Guangming, Shenzhen. Certain transactions of the Company are denominated in Renminbi, which is not freely convertible into foreign currencies. All foreign exchange transactions take place either through the Peoples Bank of China (“PBOC”) or other banks authorized to buy and sell foreign currencies at the exchange rates quoted by the PBOC. Approval of foreign currency payments by the PBOC or other institutions requires submitting a payment application form together with suppliers’ invoices, shipping documents and signed contracts.
Recent changes in accounting standards	( u ) In February 2016, the FASB issued ASU 2016-02, Lease (Subtopic 842) with subsequent amendments made via ASU 2018-01, ASU 2018-10, ASU 2018-11, ASU 2018-20 and ASU 2019-01. These updates established ASC 842, “Leases”, with the aim to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The new lease standard was effective for us on January 1, 2019. Under ASC 842, The Company classifies leases as either finance leases (formerly capital leases) or operating leases, and a right-of-use asset and lease liability are required to be recognized in the consolidated balance sheets for both finance and operating leases with a term longer than 12 months. The new lease standard required a modified retrospective transition approach and provides an optional transition method to either (1) record current existing leases as of the effective date; or (2) record leases existing as of the earliest comparative period presented in the financial statements by recasting comparative period financial statements. The Company adopted the new lease standard as of January 1, 2019 using the effective date as our date of application. As such, financial statement information and disclosures required under the new lease standard are not provided for dates and periods prior to January 1, 2019. The new lease standard provides for a number of optional practical expedients in transition, which include: (1) not requiring an entity to reassess prior conclusions about lease identification, lease classification or initial direct costs; (2) allowing an entity to use a portfolio approach for similar lease assets; (3) allowing an entity to elect an accounting policy to choose not to separate non-lease components of an agreement from lease components (by asset class); (4) allowing the use of hindsight in estimating lease term or assessing impairment of right-of-use assets; and (5) not requiring an entity to reassess prior conclusions about land easements. The Company elected all of the practical expedients permitted under the transition guidance within the new lease standard. The new lease standard also provides practical expedients for ongoing accounting. The Company elected the short-term lease recognition exemption for our real estate and equipment leases, which means that for those leases that qualify, the Company does not recognize right-of-use assets or lease liabilities and recognize the expense related to the short-term leases on a straight-line basis over the lease term and any variable lease payments in the period in which the obligation for those payments is incurred. It has also elected the practical expedient that allows us not to separate non-lease components of an agreement from lease components (for certain non-real estate assets). See Note 15 for further discussion. In June 2016, the FASB issued ASU No. 2016-13 Financial Instruments—Credit Losses (Topic 326): Measurements of Credit Losses on Financial Instruments. This Update replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. This Update will be effective for public business entities that are US SEC filers for fiscal years beginning after December 15, 2019. The adoption of ASU 2016-13 is not expected to have a material impact on the consolidated financial statements in 2020. In June 2018, the FASB issued ASU No. 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting. As a result of the Update, the accounting for share-based compensation for employees and non-employees is substantially aligned. For public business entities, this Update is for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. The adoption of ASU 2018-07 did not have a material impact on the Company’s consolidated financial statements in 2019. In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740)-Simplifying the Accounting for Income Taxes. This update simplifies the accounting for income taxes with measures, among others, including: (1) removing exception to incremental approach for intra-period tax allocation when there is a loss from continuing operations and income or a gain from other items; and (2) specifying that an entity is not required to allocate the consolidated amount of current and deferred tax expense to a legal entity that is not subject to tax in its separate financial statements. However, an entity may elect to do so (on an entity-by-entity basis) for a legal entity that is both not subject to tax and disregarded by the taxing authority. This Update will be effective for public business entities that are US SEC filers for fiscal years beginning after December 15, 2020. The adoption of ASU 2019-12 is not expected to have a material impact on the Company’s consolidated financial statements in 2020.
