Since Hitachi Chemical has the right to deliver the equity interests in PCT it holds in exchange for cash from Caladrius or PCT, the initial $19.4 million value of the non-controlling interest is considered redeemable equity, requiring it to be treated as mezzanine equity. Redeemable non-controlling interest is required to be initially measured at the initial carrying amount. If the non-controlling interest is not currently redeemable and also not probable of becoming redeemable (e.g., it is not probable a contingency that triggers redemption will be met), the non-controlling interest should be classified in mezzanine equity.

Redeemable Securities - Non-Controlling Interests

Under the March 2016 Hitachi Transaction (see Note 3), Hitachi America may, at any time following the tenth anniversary of the March 2016 Hitachi Transaction closing date on March 11, 2016, have the right on one occasion to require Caladrius or PCT to purchase all or some of the equity securities in PCT then held by Hitachi Chemical ("Hitachi Put Right") for an amount equal to the lower of (i) the fair market value of the Hitachi equity holdings and (ii) the original purchase price paid of $19.4 million on March 11, 2016 for its 19.9% ownership interest, plus interest at a rate of 2.0% per annum compounded annually; provided, however, that if Hitachi Chemical ownership interests increases subsequent to its initial ownership interest, and it offers to sell its equity holdings in excess of 21% of PCT’s outstanding equity securities, then the Company shall be required to purchase all such equity holdings of Hitachi Chemical but in no event shall the aggregate purchase price of such Hitachi Chemical equity holdings exceed $20.5 million plus interest at the rate of 2.0% per annum compounded annually.

Since Hitachi Chemical has the right to deliver the equity interests in PCT it holds in exchange for cash from Caladrius or PCT, the initial $19.4 million value of the non-controlling interest is considered redeemable equity, requiring it to be treated as mezzanine equity. Redeemable non-controlling interest is required to be initially measured at the initial carrying amount. If the non-controlling interest is not currently redeemable and also not probable of becoming redeemable (e.g., it is not probable a contingency that triggers redemption will be met), the non-controlling interest should be classified in mezzanine equity.
