The debentures may be converted into shares at the option of the holder at any time prior to maturity and may be redeemed by Superior in certain circumstances. Superior may elect to pay interest and principal upon maturity or redemption by issuing shares to a trustee in the case of interest payments, and to the debenture holders in the case of payment of principal. The number of any shares issued will be determined based on market prices for the shares at the time of issuance. Superior also has a cash conversion put option which allows Superior to settle any conversion of debentures in cash, in lieu of delivering common shares to the debenture holders of the June 2018 and October 2016 convertible debentures. The cash conversion put option has been classified as an embedded derivative and measured at fair value through net earnings (loss) (FVTNEL) (see Note 13 for further details).
13. Financial Instruments
IFRS requires disclosure around fair value and specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect Superior's market assumptions. These two types of input create the following fair-value hierarchy:
-- Level 1 - quoted prices in active markets for identical instruments.-- Level 2 - quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets.-- Level 3 - valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.
