The increase in the carrying amount is due to the accrual of deemed dividends of approximately $0.8 million, the accretion of the beneficial conversion feature of approximately $1.9 million during the three months ending March 31, 2018 and the additional BCF discounts for payment-in-kind shares accrued during the three months ending March 31, 2018 of $0.2 million.

The difference between the fair value of $32.9 million and the liquidation value of $49.5 million represents a discount of approximately $16.6 million. Beneficial Conversion Features The fair value of the common stock into which the Series A Preferred Stock is convertible exceeded the allocated purchase price fair value of the Series A Preferred Stock at the date of issuance and after redemption by approximately $44.7 and $20.1 million, respectively, resulting in a beneficial conversion feature. The Company will recognize the beneficial conversion feature as non-cash, deemed dividend to the holder of Series A Preferred Stock over the first three years the Series A Preferred Stock is outstanding, as the date the stock first becomes convertible is three years from the issue date.
