The FASB issued ASU No. 2017-11, Earnings Per Share (Topic 260) Distinguishing Liabilities From Equity (Topic 480) Derivatives and Hedging (Topic 815): I. Accounting for Certain Financial Instruments With Down Round Features II. Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests With a Scope Exception, allows a financial instrument with a down-round feature to no longer automatically be classified as a liability solely based on the existence of the down-round provision. The update also means the instrument would not have to be accounted for as a derivative and be subject to an updated fair value measurement each reporting period.

On consideration of the above factors, Bionik Laboratories Corp. (the “Company”) elected to early adopt ASU 2017-11 on July 1, 2017. The early adoption allows the Company to reduce the cost and complexity of updating the fair value measurement each reporting period and eliminate the unnecessary volatility in reported earnings created by the revaluation when the Company’s shares’ value changes. The Company presented the change in accounting policy through the retrospective application of the new accounting principle to all prior periods, as described in ASU No. 250-10-45-5, Accounting Changes and Error Corrections.

On December 21, 2017, the Company filed a Registration Statement on Form S-1 which contained audited retrospectively revised consolidated financial statements for the years ended March 31, 2017 and 2016 (the “Financial Statements”), reflecting the early adoptions of ASU No. 2017-11. This Current Report on Form 8-K is being filed to provide the Financial Statements, which are included as Exhibit 99.1 to this Current Report on Form 8-K, as well as the Financial Statements in XBRL format, which are included as exhibits to this Current Report on Form 8-K.
