SFD^® Hydrocarbon Right

During 2015, NXT acquired the rights to the SFD^® technology for use in the exploration of hydrocarbons (“Hydrocarbon Right”) from the CEO, and recorded the acquisition as an intellectual property asset on the balance sheet. The asset was recorded at the fair value of the consideration transferred, including the related tax effect of approximately $25.3 million.

The Hydrocarbon Right is being amortized on a straight line basis over its estimated useful life of 15 years. The annual amortization expense expected to be recognized is approximately $1.7 million per year for a 5 year aggregate total of $8.5 million.

SFD^® Geothermal Right

The Company acquired the SFD^® technology rights for geothermal resources (“Geothermal Right”) from Mr. George Liszicasz, the former President and CEO of NXT (“CEO”) on April 18, 2021. The consideration deliverable by the Company in connection with the acquisition of the Geothermal Right is set forth below:

1.	US$40,000 (CAD$50,310) signature payment, which became due immediately and was paid on April 22, 2021;
2.	300,000 common shares, which were issued in December 2021;
3.	CAD$15,000 signature milestone payment paid in August 2021;
4.	US$200,000 milestone payment which will become due in the event that the Company's cash balance exceeds CAD$5,000,000 due to receipt of specifically defined funds from operations; and
5.	US$250,000 milestone payment which will become due in the event that the Company executes and completes and receives full payment for an SFD® contract valued at US$10,000,000 or greater, provided such contract is entered into and completed and payment of at least US$5,000,000 is received by April 18, 2023.

As of December 31, 2022, the Company has recognized $275,610 for the acquisition Geothermal Right which is the combination of the US$40,000 (CAD$50,310) and CAD$15,000 signature payments, the value of the 300,000 common shares of $207,300 and other costs of $3,000. Before the 300,000 common shares were issued by the Company, the value of the common shares was recorded as Contributed capital. Upon Toronto Stock Exchange (the “TSX”) approval, the amount recognized of $207,300 less issuance costs of $42,697 were reclassified to common shares. The cost of the remaining two milestones will be recognized when it is deemed probable that these two milestones will be achieved by a special committee of the Board of Directors, comprised entirely of independent directors. The Board of Directors delegated authority to the special committee to determine when the milestones have been achieved. As of December 31, 2022 the remaining two milestones are still deemed not probable of being achieved.

The current book value of the Geothermal Right is being amortized on a straight line basis over its estimated useful life of 20 years. The annual amortization expense expected to be recognized is approximately $13,781 per year for a 5 year aggregate total of approximately $68,902.
