NOTE 14.  UNSECURED NOTES PAYABLE

Following is a roll-forward of notes payable:

PPL and EyGen Unsecured Notes Payable

During the year ended March 31, 2017, the Company's subsidiaries, PPL and EyGen, completed a private placement of unsecured notes (the "PPL Unsecured Notes"). The balance outstanding as of March 31, 2020 was $0.2 million.

The PPL Unsecured Notes were settled as part of the disposition of PPL in March 2021 (see Note 8, “Disposition of PPL”).

SalvaRx Unsecured Notes Payable and Warrants

In connection with the SalvaRx Acquisition in January 2019, the Company assumed $3.96 million of principal in unsecured notes due on March 2, 2021 (or earlier upon a qualifying event), that bear interest at 7% per annum (the "SalvaRx Notes"). The fair value of the SalvaRx Notes was determined to be $3.4 million at January 2019. As the SalvaRx Acquisition was a qualifying event, the SalvaRx Notes became due upon the acquisition. In December 2019, the maturity date of the SalvaRx Notes was extended to June 2021.

The holders of the SalvaRx Notes received $7,500 of warrants in respect of each $10 thousand of principal issued. The warrants vest in the event of a qualifying transaction and are exercisable at a 30% discount to the implied valuation of SalvaRx. On the Acquisition Date, the fair value of the warrants, which are included in non-controlling interest, was determined to be $2.5 million using the Black-Scholes model.

During September 2020, the Company settled the SalvaRx Notes obligations originally due in June 2021 in an aggregate principal amount of approximately $3.7 million, plus accrued interest of $0.75 million in exchange for cash payments totaling $1.77 million and 397,604 of the associated SalvaRx warrants with an exercise price of $6.64 per share. The noteholders who accepted the offer exchanged their SalvaRx warrants for an equal number of Portage shares at the same price per share. The Company accounted for the contractual value of the exercised and outstanding warrants of $2.64 million (397,604 shares at $6.64 per share) as accrued equity issuable at September 30, 2020. The Company also recorded a loss of $1.26 million during the year ended March 31, 2021, to recognize the discount between the fair value of the underlying shares on October 13, 2020, the settlement date, ($9.80 per share) and the warrant exercise (contract) price of $6.64 per share.

Four of the Company's directors, Gregory Bailey, James Mellon (former director), Steven Mintz (in trust) and Kam Shah, received, in total, 363,718 of the warrants pursuant to this transaction. Subsequent to the exercise of the warrants in October 2020, Portage had 12,083,395 and 49,701 issued and outstanding shares and warrants, respectively.

The Company also recorded a loss on early extinguishment of debt of $0.22 million in the year ended March 31, 2021.

iOx Unsecured Notes Payable

In connection with the SalvaRx Acquisition in January 2019, the Company assumed $2.0 million of 7% convertible notes issued by iOx, a wholly-owned subsidiary of SalvaRx (the “Convertible Notes”), of which the Company holds $1.9 million. As a result of the SalvaRx Acquisition, iOx became a subsidiary of the Company during the year ended March 31, 2019. In accordance with IFRS 3, the fair value, including interest receivable, of the Convertible Notes were effectively settled against the note receivable upon the business combination.

On September 8, 2021, the Company, through SalvaRx, completed a settlement of loans (including interest) to and receivables from iOx for services rendered in exchange for 23,772 ordinary shares of iOx at a price of £162. Simultaneously, the Company entered into an agreement with Oxford Sciences Innovation, Plc (“OSI”), the holder of $0.15 million notes plus accrued interest under which OSI exchanged the notes plus accrued interest for 820 shares of iOx. The Company followed the guidance provided by an IFRS Discussion Group Public Meeting dated November 29, 2016, following the general tenets of IAS 39, “Financial Instruments: Recognition and Measurement,” and IFRIC 19, “Extinguishing Financial Liabilities with Equity Instruments” and recorded the exchange at historical cost. Additionally, no profit or loss was recorded in connection with the exchange. As a result of these transactions, the Company, through SalvaRx, increased its ownership up from 60.49% to 78.32%.

NOTE 10. ACQUISITION AND BUSINESS COMBINATION

On August 13, 2018, the Company reached a definitive agreement to acquire 100% of SalvaRx, a company incorporated in the British Virgin Islands on May 6, 2015 focused on novel cancer immunotherapies and to develop clinical proof of concept, in exchange for 8,050,701 ordinary shares of the Company (the "SalvaRx Acquisition"). The SalvaRx Acquisition was completed on January 8, 2019 (the "Acquisition Date") upon receiving shareholder and regulatory approval.  Shares issued by the Company on acquisition were valued at $92.6 million based on the market price of the Company shares of $11.50 per share on the Acquisition Date. Portage is the accounting acquirer as the controlling group of shareholders of the Company increased their holdings, retained majority of voting rights after the acquisition and the Company's management prior to the acquisition continued as management of the combined company. Four of the Company's Board members are also directors of SalvaRx (see Note 21, “Related Party Transactions”). Notwithstanding the high degree of common ownership between the companies, this was not considered a common control transaction as no single individual held a controlling interest and no contractual arrangement exists among the group of shareholders.

In connection with the SalvaRx Acquisition, the Company acquired SalvaRx's five invested entities and subsidiaries: iOx and Saugatuck (consolidated subsidiary with non-controlling interest), Intensity (investment in private company) (see Note 9, “Investments in Private Companies”), Nekonal (joint venture with no fair value due to a dispute with Nekonal, see below), and Rift (no fair value as operations are discontinued).  In connection with the SalvaRx Acquisition, the Company also acquired an option from Nekonal SARL that gives SalvaRx the right to acquire shares in Nekonal for €50 ($55 USD) per share for four years.  On January 8, 2019, the acquisition date, the fair value of option was determined to be $0 due to a dispute with Nekonal.

SalvaRx and Nekonal were involved in a dispute regarding Nekonal's claim that it attained a development milestone that would require SalvaRx to provide the next tranche of funding. SalvaRx claims that Nekonal committed a breach of duties and fraud on its minority shareholders with respect to its assumption that the milestone has been attained. Nekonal management has counterclaimed that SalvaRx is in breach of contract with respect to the funding arrangement. While litigation was threatened, no legal proceedings have commenced. In fiscal 2021, the Company abandoned its interest in Nekonal.

The acquisition of SalvaRx allowed the Company to acquire interest in the development of nine immune-oncology products. SalvaRx has three in-process research and development ("IPR&D") projects identified.

The following table presents unaudited supplemental pro forma consolidated net income based on SalvaRx's historical reporting periods as if the SalvaRx Acquisition had occurred as of April 1, 2018 (in thousands):

Contingent Liability

A contingent liability is a possible obligation that arises from past events and of which the existence will be confirmed only by the occurrence or non-occurrence of one or more uncertain future events not within the control of the Corporation; or a present obligation that arises from past events (and therefore exists), but is not recognized because it is not probable that a transfer or use of assets, provision of services or any other transfer of economic benefits will be required to settle the obligation; or the amount of the obligation cannot be estimated reliably.

Impairment of Indefinite Life Intangible Assets other than Goodwill

At the end of each annual reporting period and whenever there is an indication that an indefinite life intangible asset may be impaired, the Company reviews the carrying amounts of such intangible assets to determine whether there is any indication that those assets have suffered an impairment loss. If any such indication exists, the recoverable amount of the asset is estimated to determine the extent of impairment loss (if any). When it is not possible to estimate the recoverable amount of any individual asset, the Company estimates the recoverable amount of the cash-generating unit to which the asset belongs. When a reasonable and consistent basis of allocation can be identified, corporate assets are also allocated to individual cash-generating units ("CGU" or "CGUs"), or the smallest group of cash-generating units for which a reasonable and consistent allocation basis can be identified.

Recoverable amount is the higher of fair value less costs of disposal and value in use. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset for which the estimates of future cash flows have not been adjusted.
