CCPS is a financial instrument in which preference shares issued to investors are converted to equity shares at the time of maturity. CCD, on the other hand, is a hybrid instrument that typically starts off as debt with regular servicing of interest to the holders, till its conversion to equity shares.
In the recent past, most new age start-ups operating in areas like e-commerce, ride-sharing and hotel aggregation have raised money by issuing such instruments. Hotel aggregator Oyo, for example, raised $100 million in December last year from Singaporean ride-hailing company Grab through the issuance of 2,884 convertible preference shares. In September of 2018 too, the Ritesh Agarwal-founded company had raised $1 billion from Japanese conglomerate SoftBank through issuance of similar instruments. Likewise, e-commerce giant Flipkart had used these routes to raise funds in multiple rounds before Walmart picked up controlling stake with an investment of $16 billion last May.
