IFC convertible loan

On February 18, 2014, the Group borrowed from International Finance Corporation (“IFC”) a loan with principal amount of US$20,000 which is repayable by two equal installments on October 15, 2018 and April 15, 2019. The loan gives IFC the right to convert the loan in whole or in part, at any time prior to the fifth anniversary of the date of the disbursement of the loan, into ADSs of the Company at the conversion price in effect at such time. The conversion price is initially set at US$6.90 per ADS subject to adjustments as set forth in the loan agreement. The conversion and other features (i.e. the redemption option upon certain contingencies, step down interest feature), which are not clearly and closely related to the debt host contract, are bifurcated and accounted for as a compound derivative. The compound derivative is accounted for as a liability at fair value for each reporting period (note 19).

The IFC convertible loan was initially recorded as long-term bank borrowing of US$14,149 which equal to the US$20,000 proceeds received net of the fair value of the bifurcated compound derivative of US$5,851 on the issuance date. The host debt instrument is accreted to the redemption value on the maturity date using of the effective interest method.

On October 12, 2015, the Group entered into a repayment agreement with IFC pursuant to which, principle of US$10,000 will be repaid by December 31, 2015 and the remaining US$10,000 will be repaid on February 29, 2016 and May 31, 2016 in two equal installments. The amendment on repayment term is accounted for under extinguishment accounting. In accordance with ASC 470, Debt, for the extinguishments of debt, the difference between the reacquisition price (which includes any premium) and the net carrying amount of the debt being extinguished (which includes any deferred debt issuance costs) should be recognized as a gain or loss when the debt is extinguished. A loss on debt extinguishment of RMB36,648 was recognized in the consolidated statement of comprehensive income (loss) for the year ended December 31, 2015. The outstanding balance of the IFC loan amounted to RMB64,804 was reclassified to “long-term bank and other borrowings, current portion” in the consolidated balance sheet as of December 31, 2015 and was repaid in February 2016. The compound derivative liability was extinguished upon the repayment of the IFC C loan.
