No other changes have been made to the Original 6-K. This Amendment does not reflect events that may have occurred subsequent to the original submission date and does not modify or update in any way the disclosures made in the Original 6-K.

This Amendment and each of the exhibits to this Amendment are hereby incorporated by reference into the registration statements on Form F-3 (No. 333-213730 and No. 333-183143) of the Company.

This Amendment contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, and Section 21E of the Securities Exchange Act of 1934. These statements relate to future events or the Company’s future financial performance. The Company has attempted to identify forward-looking statements by terminology including “anticipates”, “believes”, “expects”, “can”, “continue”, “could”, “estimates”, “intends”, “may”, “plans”, “potential”, “predict”, “should” or “will” or the negative of these terms or other comparable terminology. These statements are only predictions, uncertainties and other factors may cause the Company’s actual results, levels of activity, performance or achievements to be materially different from any future results, levels of activity, performance or achievements expressed or implied by these forward-looking statements. The information in this Amendment is not intended to project future performance of the Company. Although the Company believes that the expectations reflected in the forward-looking statements are reasonable, the Company does not guarantee future results, levels of activity, performance or achievements. The Company’s expectations are as of the date this Amendment is filed, and the Company does not intend to update any of the forward-looking statements after the date this Amendment is filed to conform these statements to actual results, unless required by law.

The forward-looking statements included in this Amendment are subject to risks, uncertainties and assumptions about the Company’s businesses and business environments. These statements reflect the Company’s current views with respect to future events and are not a guarantee of future performance. Actual results of the Company’s operations may differ materially from information contained in the forward-looking statements as a result of risk factors some of which include, among other things: continued compliance with government regulations regarding cord blood banking in the People’s Republic of China, or PRC and any other jurisdiction in which the Company conducts its operations; changing legislation or regulatory environments (including the relaxation of China’s one child policy) in the PRC and any other jurisdiction in which the Company conducts its operations; the acceptance by subscribers of the Company’s different pricing and payment options and reaction to the introduction of the Company’s premium-quality pricing strategy; demographic trends in the regions of the PRC in which the Company is the exclusive licensed cord blood banking operator; labor and personnel relations; the existence of a significant shareholder able to influence and direct the corporate policies of the Company; credit risks affecting the Company’s revenue and profitability; changes in the healthcare industry, including those which may result in the use of stem cell therapies becoming redundant or obsolete; the Company’s ability to effectively manage its growth, including maintaining effective controls and procedures and attracting and retaining key management and personnel; changing interpretations of generally accepted accounting principles; the availability of capital resources, including in the form of capital markets financing opportunities, in light of industry developments affecting issuers that have pursued a “reverse merger” with an operating company based in the PRC, as well as general economic conditions; the proposed transactions between an affiliate of Golden Meditech Holdings Limited (“Golden Meditech”) and Nanjing Ying Peng Hui Kang Medical Industry Investment Partnership (limited partnership); and other relevant risks detailed in the Company’s filings with the Securities and Exchange Commission in the United States.

Notes to the unaudited condensed consolidated financial statements

(Amounts expressed in thousands, except share data)

1Principal activities and basis of presentation

(a)Principal activities

China Cord Blood Corporation (the “Company”) and its subsidiaries (collectively the “Group”) are principally engaged in the provision of umbilical cord blood storage and ancillary services in the People’s Republic of China (the “PRC”). As of September 30, 2017, the Group has three operating cord blood banks in the Beijing municipality, the Guangdong province and the Zhejiang province, the PRC. The Company’s shares are listed on the New York Stock Exchange.

The Group provides cord blood testing, processing and storage services under the direction of subscribers for a cord blood processing fee and a storage fee. The Group also tests, processes and stores donated cord blood, and provides matching services to the public for a fee.

(b)Basis of presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted as permitted by rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). The condensed consolidated balance sheet as of March 31, 2017 was derived from the audited consolidated financial statements of the Company. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the March 31, 2017 audited consolidated financial statements of the Company included in the Company’s annual report on Form 20-F for the year ended March 31, 2017.

In the opinion of management, all adjustments (which include normal recurring adjustments) necessary to present a fair statement of the financial position as of September 30, 2017, the results of operations for the three months and six months ended September 30, 2016 and 2017, and cash flows for the six months ended September 30, 2016 and 2017 have been made.

For the convenience of the readers, certain amounts as of and for the three months and six months ended September 30, 2017 included in the accompanying unaudited condensed consolidated financial statements have been translated into U.S. dollars at the rate of US$1.00 = RMB6.6533, being the spot exchange rate of U.S. dollars in effect on September 29, 2017 for cable transfers in RMB per U.S. dollar as certified for customs purposes by the Federal Reserve, the central bank of the United States of America. No representation is made that the RMB amounts could have been, or could be, converted into U.S. dollars at that rate or at any other rate on September 30, 2017 or at any other date.

2Summary of significant accounting policies

(a)Principles of consolidation

The accompanying unaudited condensed consolidated financial statements include the financial statements of the Company, its majority-owned subsidiaries and a restricted share unit related variable interest entity in which the Company is the primary beneficiary. For consolidated subsidiaries where the Company’s ownership is less than 100%, the portion of equity (net assets) in a subsidiary not attributable, directly or indirectly, to the Company, are presented as non-controlling interests. All significant intercompany balances and transactions have been eliminated on consolidation.

(b)Use of estimates

The preparation of the consolidated financial statements in accordance with U.S. 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 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 the estimate of selling price for individual deliverables in multiple-element revenue arrangements, the estimated future number of successful match units over the estimated weighted average remaining useful life of donated cord blood units, the useful lives of property, plant and equipment and intangible assets, the recoverability of property, plant and equipment and intangible assets, the collectibility of accounts receivables, the realizability of inventories and deferred tax assets and the fair values of share-based compensation.

4Convertible notes

On April 27 and October 3, 2012, the Company completed the sale of US$65,000 and US$50,000 in aggregate principal amount of 7% senior unsecured convertible notes to Brilliant China Healthcare Investment Limited (formerly known as KKR China Healthcare Investment Limited) (“BCHIL”) (the “KKR Notes”) and Golden Meditech (the “GM Notes,” and collectively the “Notes”), respectively. The GM Notes were subsequently sold to Cordlife Group Limited and Magnum Opus International Holdings Limited in November 2014. In May 2015, Golden Meditech initiated a series of agreements and transactions to acquire US$115,000 in aggregate principal amount of the Notes. As of January 2016, Golden Meditech, through its wholly owned subsidiary, Golden Meditech Stem Cells (BVI) Company Limited (“GMSC”) became the owner of the Notes.

In April 2017, GMSC exercised the conversion of the Notes of US$115,000 at a conversion price of US$2.838 per share, which resulted in the issuance of 40,521,494 ordinary shares of the Company. Subsequent to such conversion, the Company has no outstanding convertible notes.

The carrying amounts of the Notes, net are summarized in the following table:

	March 31,		September 30,
	2017		2017	2017
	RMB		RMB	US$
Principal amount of the KKR Notes	449,608		—	—

Cumulative interest payable	236,389		—	—
Less: Unamortized debt issuance costs	(695	)	—	—
Total convertible notes, net	1,031,154		—	—

The Company accrued interest on the Notes based on the guaranteed 12% internal rate of return per annum. The difference between the accrued interest rate of 12% and the coupon rate of 7% of the Notes is recorded in convertible notes in the consolidated balance sheet as of March 31, 2017. Debt issuance costs in connection with the issuance of convertible notes are amortized from the date the Notes were issued to the earliest date the holders of the Notes can demand payment, which is five years. Upon the conversion of the Notes, the carrying value of the Notes (net of the cost of shares issued) were credited to additional paid-in capital.

Interest relating to the Notes was recognized as follows:

	Three months ended September 30,			Six months ended September 30,

(“Beijing Jiachenhong”) received approval from the tax authority on the renewal of its High and New Technology Enterprises (“HNTE”) status which entitled it to the preferential income tax rate of 15% effective retroactively from January 1, 2014 to December 31, 2016. Beijing Jiachenhong is in the process of reapplication for its HNTE status which will enable it to the preferential income tax rate of 15% from January 1, 2017 to December 31, 2019.

In April 2014, Guangzhou Municipality Tianhe Nuoya Bio-engineering Co., Ltd. (“Guangzhou Nuoya”) received approval from the tax authority on the renewal of its HNTE status which entitled it to the preferential income tax rate of 15% effective retroactively from January 1, 2013 to December 31, 2015. In March 2017, Guangzhou Nuoya received approval from the tax authority on the renewal of its HNTE status which entitled it to the preferential income tax rate of 15% effective retroactively from January 1, 2016 to December 31, 2018.

In January 2016, Zhejiang Lukou Biotechnology Co., Ltd. (“Zhejiang Lukou”) received approval from the tax authority that it qualified as a HNTE which entitled it to the preferential income tax rate of 15% effective retrospectively from January 1, 2015 to December 31, 2017.

The Enterprise Income Tax Law and its implementation rules also impose a withholding tax at 10%, unless reduced by a tax treaty or agreement, for dividends receivable by non-PRC-resident enterprises from PRC-resident enterprises in respect of earnings accumulated beginning on January 1, 2008. As of March 31, 2016, the Company has provided aggregated amount of RMB14,300 for withholding income tax on a portion of the undistributed earnings of its PRC subsidiaries according to management’s reinvestment plan. No income taxes were provided for the remaining undistributed earnings which are intended to be reinvested indefinitely in the PRC. During the year ended March 31, 2017, a reversal of withholding income tax of RMB14,300 was made due to the change in management’s future reinvestment plan as all undistributed earnings of the Company’s PRC subsidiaries are intended to be reinvested indefinitely in the PRC in the foreseeable future. As of September 30, 2017, such undistributed earnings that may be subject to the withholding tax amounted to RMB1,797,239 (US$270,128) and the related unrecognized deferred tax liability was RMB179,724 (US$27,013).

The Company’s effective income tax rates for the three months ended September 30, 2016 and 2017 were 42.2% and 17.5%, and were 42.1% and 17.9% for the six months ended September 30, 2016 and 2017, respectively. The effective income tax rates for the three months and six months ended September 30, 2016 and 2017 differ from the PRC statutory income tax rate of 25% primarily due to the effect of withholding tax and the effect of non-PRC entities not being subject to income tax, which is offset by the effect of Beijing Jiachenhong, Guangzhou Nuoya and Zhejiang Lukou’s preferential tax treatments.

As of and for the three months and six months ended September 30, 2017, the Company did not have any material unrecognized tax benefits and thus no interest and penalties related to unrecognized tax benefits were recorded. In addition, the Company does not expect that the amount of unrecognized tax benefits will change significantly within the next twelve months.

6Earnings per share

The following table sets forth the computation of basic and diluted earnings per share for the three months and six months ended September 30, 2016 and 2017 respectively:

		Three months ended September 30,

Earnings allocated to participating convertible notes	(i)	—	—	—
Net income for basic and diluted net income per share		32,363	136,730	20,551
Denominator:
Weighted average ordinary shares outstanding for basic and diluted net income per share		73,003,248	112,196,168	112,196,168
Earnings per share
- Basic		0.44	1.22	0.18
- Diluted	(ii)	0.44	1.22	0.18

Notes:

(i)The outstanding convertible notes provide the holders with the ability to participate in any excess cash dividend. Excess cash dividend means any cash dividend to holders of shares that, together with all other cash dividends previously paid to holders of shares in the same financial year, exceeds, on a per share basis, an amount equal to the interest that has accrued and shall accrue at 7% coupon interest rate in such financial year divided by the number of shares into which the notes are convertible at the conversion price then in effect on the relevant record date. Therefore, net income attributable to the Company’s shareholders is reduced by such allocated earnings to participating convertible notes for each reporting period in both basic and diluted net income per share computation. For the three months ended September 30, 2016 and six months ended September 30, 2016 and 2017, as there was no excess cash dividend, no earnings were allocated to participating convertible notes. There was no such participating right effect for the three months ended September 30, 2017 as all outstanding convertible notes were fully converted in April 2017.

(ii)During the three months ended September 30, 2016 and six months ended September 30, 2016 and 2017, the Company had potentially dilutive ordinary shares of 40,521,494 representing shares issuable upon conversion of the outstanding convertible notes (Note 4). Such potentially dilutive ordinary shares were excluded from diluted net income per share computation because their effects would have been anti-dilutive.

1Principal activities and basis of presentation

(a)Principal activities

China Cord Blood Corporation (the “Company”) and its subsidiaries (collectively the “Group”) are principally engaged in the provision of umbilical cord blood storage and ancillary services in the People’s Republic of China (the “PRC”). As of September 30, 2017, the Group has three operating cord blood banks in the Beijing municipality, the Guangdong province and the Zhejiang province, the PRC. The Company’s shares are listed on the New York Stock Exchange.

The Group provides cord blood testing, processing and storage services under the direction of subscribers for a cord blood processing fee and a storage fee. The Group also tests, processes and stores donated cord blood, and provides matching services to the public for a fee.

(b)Basis of presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted as permitted by rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). The condensed consolidated balance sheet as of March 31, 2017 was derived from the audited consolidated financial statements of the Company. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the March 31, 2017 audited consolidated financial statements of the Company included in the Company’s annual report on Form 20-F for the year ended March 31, 2017.

In the opinion of management, all adjustments (which include normal recurring adjustments) necessary to present a fair statement of the financial position as of September 30, 2017, the results of operations for the three months and six months ended September 30, 2016 and 2017, and cash flows for the six months ended September 30, 2016 and 2017 have been made.

For the convenience of the readers, certain amounts as of and for the three months and six months ended September 30, 2017 included in the accompanying unaudited condensed consolidated financial statements have been translated into U.S. dollars at the rate of US$1.00 = RMB6.6533, being the spot exchange rate of U.S. dollars in effect on September 29, 2017 for cable transfers in RMB per U.S. dollar as certified for customs purposes by the Federal Reserve, the central bank of the United States of America. No representation is made that the RMB amounts could have been, or could be, converted into U.S. dollars at that rate or at any other rate on September 30, 2017 or at any other date.

Summary of significant accounting policies

2Summary of significant accounting policies

(a)Principles of consolidation

The accompanying unaudited condensed consolidated financial statements include the financial statements of the Company, its majority-owned subsidiaries and a restricted share unit related variable interest entity in which the Company is the primary beneficiary. For consolidated subsidiaries where the Company’s ownership is less than 100%, the portion of equity (net assets) in a subsidiary not attributable, directly or indirectly, to the Company, are presented as non-controlling interests. All significant intercompany balances and transactions have been eliminated on consolidation.

(b)Use of estimates

The preparation of the consolidated financial statements in accordance with U.S. 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 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 the estimate of selling price for individual deliverables in multiple-element revenue arrangements, the estimated future number of successful match units over the estimated weighted average remaining useful life of donated cord blood units, the useful lives of property, plant and equipment and intangible assets, the recoverability of property, plant and equipment and intangible assets, the collectibility of accounts receivables, the realizability of inventories and deferred tax assets and the fair values of share-based compensation.

On April 27 and October 3, 2012, the Company completed the sale of US$65,000 and US$50,000 in aggregate principal amount of 7% senior unsecured convertible notes to Brilliant China Healthcare Investment Limited (formerly known as KKR China Healthcare Investment Limited) (“BCHIL”) (the “KKR Notes”) and Golden Meditech (the “GM Notes,” and collectively the “Notes”), respectively. The GM Notes were subsequently sold to Cordlife Group Limited and Magnum Opus International Holdings Limited in November 2014. In May 2015, Golden Meditech initiated a series of agreements and transactions to acquire US$115,000 in aggregate principal amount of the Notes. As of January 2016, Golden Meditech, through its wholly owned subsidiary, Golden Meditech Stem Cells (BVI) Company Limited (“GMSC”) became the owner of the Notes.

In April 2017, GMSC exercised the conversion of the Notes of US$115,000 at a conversion price of US$2.838 per share, which resulted in the issuance of 40,521,494 ordinary shares of the Company. Subsequent to such conversion, the Company has no outstanding convertible notes.

The carrying amounts of the Notes, net are summarized in the following table:

Less: Unamortized debt issuance costs	(695	)	—	—
Total convertible notes, net	1,031,154		—	—

The Company accrued interest on the Notes based on the guaranteed 12% internal rate of return per annum. The difference between the accrued interest rate of 12% and the coupon rate of 7% of the Notes is recorded in convertible notes in the consolidated balance sheet as of March 31, 2017. Debt issuance costs in connection with the issuance of convertible notes are amortized from the date the Notes were issued to the earliest date the holders of the Notes can demand payment, which is five years. Upon the conversion of the Notes, the carrying value of the Notes (net of the cost of shares issued) were credited to additional paid-in capital.

Interest relating to the Notes was recognized as follows:

The Company’s PRC subsidiaries are subject to PRC statutory income tax rate of 25% unless otherwise specified.

In January 2015, Beijing Jiachenhong Biological Technologies Co., Ltd. (“Beijing Jiachenhong”) received approval from the tax authority on the renewal of its High and New Technology Enterprises (“HNTE”) status which entitled it to the preferential income tax rate of 15% effective retroactively from January 1, 2014 to December 31, 2016. Beijing Jiachenhong is in the process of reapplication for its HNTE status which will enable it to the preferential income tax rate of 15% from January 1, 2017 to December 31, 2019.

In April 2014, Guangzhou Municipality Tianhe Nuoya Bio-engineering Co., Ltd. (“Guangzhou Nuoya”) received approval from the tax authority on the renewal of its HNTE status which entitled it to the preferential income tax rate of 15% effective retroactively from January 1, 2013 to December 31, 2015. In March 2017, Guangzhou Nuoya received approval from the tax authority on the renewal of its HNTE status which entitled it to the preferential income tax rate of 15% effective retroactively from January 1, 2016 to December 31, 2018.

In January 2016, Zhejiang Lukou Biotechnology Co., Ltd. (“Zhejiang Lukou”) received approval from the tax authority that it qualified as a HNTE which entitled it to the preferential income tax rate of 15% effective retrospectively from January 1, 2015 to December 31, 2017.

The Enterprise Income Tax Law and its implementation rules also impose a withholding tax at 10%, unless reduced by a tax treaty or agreement, for dividends receivable by non-PRC-resident enterprises from PRC-resident enterprises in respect of earnings accumulated beginning on January 1, 2008. As of March 31, 2016, the Company has provided aggregated amount of RMB14,300 for withholding income tax on a portion of the undistributed earnings of its PRC subsidiaries according to management’s reinvestment plan. No income taxes were provided for the remaining undistributed earnings which are intended to be reinvested indefinitely in the PRC. During the year ended March 31, 2017, a reversal of withholding income tax of RMB14,300 was made due to the change in management’s future reinvestment plan as all undistributed earnings of the Company’s PRC subsidiaries are intended to be reinvested indefinitely in the PRC in the foreseeable future. As of September 30, 2017, such undistributed earnings that may be subject to the withholding tax amounted to RMB1,797,239 (US$270,128) and the related unrecognized deferred tax liability was RMB179,724 (US$27,013).

The Company’s effective income tax rates for the three months ended September 30, 2016 and 2017 were 42.2% and 17.5%, and were 42.1% and 17.9% for the six months ended September 30, 2016 and 2017, respectively. The effective income tax rates for the three months and six months ended September 30, 2016 and 2017 differ from the PRC statutory income tax rate of 25% primarily due to the effect of withholding tax and the effect of non-PRC entities not being subject to income tax, which is offset by the effect of Beijing Jiachenhong, Guangzhou Nuoya and Zhejiang Lukou’s preferential tax treatments.

As of and for the three months and six months ended September 30, 2017, the Company did not have any material unrecognized tax benefits and thus no interest and penalties related to unrecognized tax benefits were recorded. In addition, the Company does not expect that the amount of unrecognized tax benefits will change significantly within the next twelve months.

Notes:

(i) The outstanding convertible notes provide the holders with the ability to participate in any excess cash dividend. Excess cash dividend means any cash dividend to holders of shares that, together with all other cash dividends previously paid to holders of shares in the same financial year, exceeds, on a per share basis, an amount equal to the interest that has accrued and shall accrue at 7% coupon interest rate in such financial year divided by the number of shares into which the notes are convertible at the conversion price then in effect on the relevant record date. Therefore, net income attributable to the Company’s shareholders is reduced by such allocated earnings to participating convertible notes for each reporting period in both basic and diluted net income per share computation. For the three months ended September 30, 2016 and six months ended September 30, 2016 and 2017, as there was no excess cash dividend, no earnings were allocated to participating convertible notes. There was no such participating right effect for the three months ended September 30, 2017 as all outstanding convertible notes were fully converted in April 2017.

(ii) During the three months ended September 30, 2016 and six months ended September 30, 2016 and 2017, the Company had potentially dilutive ordinary shares of 40,521,494 representing shares issuable upon conversion of the outstanding convertible notes (Note 4). Such potentially dilutive ordinary shares were excluded from diluted net income per share computation because their effects would have been anti-dilutive.

Summary of significant accounting policies

Principles of consolidation

(a)Principles of consolidation

The accompanying unaudited condensed consolidated financial statements include the financial statements of the Company, its majority-owned subsidiaries and a restricted share unit related variable interest entity in which the Company is the primary beneficiary. For consolidated subsidiaries where the Company’s ownership is less than 100%, the portion of equity (net assets) in a subsidiary not attributable, directly or indirectly, to the Company, are presented as non-controlling interests. All significant intercompany balances and transactions have been eliminated on consolidation.

Use of estimates

(b)Use of estimates

The preparation of the consolidated financial statements in accordance with U.S. 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 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 the estimate of selling price for individual deliverables in multiple-element revenue arrangements, the estimated future number of successful match units over the estimated weighted average remaining useful life of donated cord blood units, the useful lives of property, plant and equipment and intangible assets, the recoverability of property, plant and equipment and intangible assets, the collectibility of accounts receivables, the realizability of inventories and deferred tax assets and the fair values of share-based compensation.
