At any time prior to February 28, 2021, the Company may at its option redeem the February 2021 Senior Secured Notes, in whole but not in part, at a redemption price equal to 100.0% of the principal amount of the February 2021 Senior Secured Notes plus the Applicable Premium as of, and accrued and unpaid interest, if any, to (but not including) the redemption date. “Applicable Premium” means with respect to any February 2021 Senior Secured Note at any redemption date, the greater of (i) 1.00% of the principal amount of such February 2021 Senior Secured Note and (ii) the excess of (A) the present value at such redemption date of the principal amount of such February 2021 Senior Secured Note, plus all required remaining scheduled interest payments due on such February 2021 Senior Secured Note through the maturity date of the February 2021 Senior Secured Notes (but excluding accrued and unpaid interest to the redemption date), computed using a discount rate equal to the Adjusted Treasury Rate (as defined in the February 2021 Indenture) plus 100 basis points, over (B) the principal amount of such February 2021 Senior Secured Note on such redemption date.

Income taxes

9. Income taxes

(a) Effective tax rate

Our effective income tax rate (“ETR”) was 59.0% in the first six months of 2017 compared to 43.8% in the first six months of 2016. The ETR was different from the statutory tax rate of 25% due to the effects of the land appreciation tax (“LAT”), the corporate income tax (“CIT”) benefit of LAT, outside basis differences and changes in unrecognized tax benefits. The change in the effective income tax rate is primarily due to a LAT rebate of approximately US$9.1 million during the six months ended June 30, 2016 related to a completed project that was liquidated and settled with the local tax bureaus on favorable terms.

(b) Liability for unrecognized tax benefit

The following table summarizes the activity related to the Group’s unrecognized tax benefits:

	US$
Balance as of December 31, 2016 (Audited)		20,491,988
Movement in current year due to foreign exchange rate fluctuation (unaudited)		1,779
Balance as of June 30, 2017 (Unaudited)		20,493,767

The current year movement in the liability for unrecognized tax benefits of US$1,779 was caused by the US$-RMB exchange rate, and therefore was recorded as other comprehensive income arising from foreign currency translation.

On January 1, 2017, the Group adopted Accounting Standards Update (“ASU”) No. 2015-17 Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes and classified deferred tax assets and liabilities as noncurrent on the consolidated balance sheets for all periods presented.

Segment Reporting [Abstract]

Segment reporting

12. Segment reporting

The Group’s long-lived assets and revenue are mainly located in and derived from the PRC. Starting in 2012, a relatively smaller portion of the Group’s long-lived assets and revenue are located in and derived from the United States. The Group considers that each of its individual property developments is a discrete operating segment. The Group has aggregated its segments in the PRC on a provincial basis as property development projects undertaken within a province have similar expected economic characteristics, type of properties offered, customers and market and regulatory environment. The Group’s reportable operating segments are comprised of Henan Province, Shandong Province, Jiangsu Province, Sichuan Province, Beijing, Hainan Province, Hunan Province, Shaanxi Province, Shanghai, Guangdong Province and Tianjin in the PRC; and the United States.

Each geographic operating segment is principally engaged in the construction and development of residential real estate units. The “other” category relates to investment holdings, property management services, installation of intercom systems, landscaping, engineering and management, real estate sale, purchase and lease activities.

The Group’s chief operating decision maker relies upon net sales, gross profit and net income when making decisions about allocating resources and assessing performance of the Group. Net sales for geographic segments are generally based on the location of the project development. Net income for each segment includes net sales to third parties, related cost of sales and operating expenses directly attributable to the segment. Capital expenditures for each segment includes cost for acquisition of subsidiaries, vehicles, fixtures and furniture and computer network equipment and accumulation of properties held for lease related to newly completed projects.

No single customer accounted for more than 10% of net sales for the six months ended June 30, 2016 and 2017.

Contingencies

As of June 30, 2017, the Group provided guarantees of US$1,480,495,108 (December 31, 2016: US$1,672,868,791), in favor of its customers in respect of mortgage loans granted by banks to such customers for their purchases of the Group’s properties where the underlying real estate ownership certificates can be provided to the banks on a time delay manner due to administrative procedures in the PRC. Pursuant to the terms of the guarantees, upon default in mortgage payments by these purchasers, the Group is responsible to repay the outstanding mortgage principal together with the accrued interest and penalty owed by the defaulted purchasers to the bank and the Group is entitled to take over the legal titles and possession of the related properties. The Group’s guarantee period starts from the date of grant of the relevant mortgage loan and ends upon issuance of real estate ownership certificate which will generally be available within six to twelve months after the purchaser takes possession of the relevant property.

The fair value of the guarantees is not significantly different than the net realizable value of the properties and management considers that in case of default in payments, the net realizable value of the related properties can cover the repayment of the outstanding mortgage principal together with the accrued interest and penalty and therefore no provision has been made for the guarantees.

On May 30, 2014, the Modern City project developed by Henan Xinyuan Real Estate Co., Ltd., completed the LAT final settlement with the local tax bureau. The Company received a tax clearance certificate, which confirmed that the Company’s accrual under the deemed profit method was adequate and there were no additional tax adjustments assessed by the local tax bureau as of May 30, 2014. Based on the above, management performed a reassessment and concluded that the likelihood of the contingency amounted to US$16.2 million in relation to deemed profit method being overturned is only reasonably possible as of June 30, 2017.

In December 2016, 421 Kent Development LLC (“421 Kent”), the property company for the Group’s Oosten project, terminated its contract with its general contractor. The contractor subsequently filed a lawsuit in New York County Supreme court against 421 Kent for approximately US$20 million and punitive damages. In addition, the contractor has filed mechanics liens against 421 Kent for approximately US$20 million. 421 Kent believes the contractor’s claims are without merit and intends to contest vigorously such claims. At this stage of the proceedings, 421 Kent cannot predict the outcome of this lawsuit or a judgment against 421 Kent, whether in whole or in part, may result in a loss, if any. And an estimate for the reasonably possible loss or a range of reasonably possible losses cannot be made at this time.

In May 2015, XIN Development Management East, LLC (“XDME”) filed an arbitration claim totalling US$10 million which was subsequently reduced for the purpose of a prior mediation to US$8 million against Wanks Adams Slavin Associates LLP (“WASA”), the design company for the Group’s Oosten project. WASA has asserted a total of approximately US$8.5 million in counterclaims. XDME believes WASA’s counterclaims are without merit and intends to contest vigorously such claims. At this stage of the proceedings, XDME cannot predict the outcome of this arbitration against XDME, whether in whole or in part, may result in a loss, if any. And an estimate for the reasonably possible loss or a range of reasonably possible losses cannot be made at this time.
