Redeemable Securities - Non-Controlling Interests	Redeemable Securities - Non-Controlling Interests Under the 2016 Hitachi Transaction (see Note 3), Hitachi, at any time following the tenth anniversary of the 2016 Hitachi Transaction closing date on March 11, 2016, had 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 ("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's ownership interests increased subsequent to its initial ownership interest, and it offered to sell its equity holdings in excess of 21% of PCT’s outstanding equity securities, then the Company would have been required to purchase all such equity holdings of Hitachi Chemical but in no event would 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. As of December 31, 2016, since Hitachi had the right to deliver the equity interests in PCT it held in exchange for cash from Caladrius or PCT, the initial $19.4 million value of the non-controlling interest was 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. Concurrent with 2017 Hitachi Transaction (see Note 3), the Hitachi Put Right was eliminated, and $14.7 million previously classified as Redeemable Securities was classified to Additional Paid in Capital. In addition, the remaining portion classified as Redeemable Securities of $4.7 million was classified to Non-Controlling Interests, representing Hitachi's ownership interest in PCT at the time of the 2016 Hitachi Transaction, which was subsequently eliminated upon the 2017 Hitachi transaction and included the PCT gain on sale.

Redeemable Securities - Non-Controlling Interests

Under the 2016 Hitachi Transaction (see Note 3), Hitachi, at any time following the tenth anniversary of the 2016 Hitachi Transaction closing date on March 11, 2016, had 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 ("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's ownership interests increased subsequent to its initial ownership interest, and it offered to sell its equity holdings in excess of 21% of PCT’s outstanding equity securities, then the Company would have been required to purchase all such equity holdings of Hitachi Chemical but in no event would 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.

As of December 31, 2016, since Hitachi had the right to deliver the equity interests in PCT it held in exchange for cash from Caladrius or PCT, the initial $19.4 million value of the non-controlling interest was 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.

Concurrent with 2017 Hitachi Transaction (see Note 3), the Hitachi Put Right was eliminated, and $14.7 million previously classified as Redeemable Securities was classified to Additional Paid in Capital. In addition, the remaining portion classified as Redeemable Securities of $4.7 million was classified to Non-Controlling Interests, representing Hitachi's ownership interest in PCT at the time of the 2016 Hitachi Transaction, which was subsequently eliminated upon the 2017 Hitachi transaction and included the PCT gain on sale.
