("Ziff Davis"). In connection with the acquisition, the issued and outstanding capital stock was exchanged for shares of Series A Cumulative Participating Preferred Stock ("Series A Stock") of Ziff Davis. Ziff Davis is accounted for as a consolidated subsidiary as of the date of acquisition. Certain minority interest holders have an ownership in Series A Stock which is being accounted for as a non-controlling interest.

The Series A Stock is subject to mandatory repayment or redemption on November 9, 2017, which Ziff Davis may repay or redeem the Series A at its option prior to the mandatory repayment or redemption date.

The Series A Stock meets the definition of a mandatorily redeemable financial instrument which requires liability classification and remeasurement at each reporting period on the consolidated subsidiaries financial statements. As the fair value of the Series A Stock was less than the mandatory redemption amount at issuance, periodic accretions using the interest method are made so that the carrying amount equals the redemption amount on the mandatory redemption date.
