The February 2014 convertible note discussed in Note 6 had a reset provision and a dilutive issuance clause that gave rise to a derivative liability. The reset provision provided for the conversion price to be adjusted downward in the event that the Company issued any securities at a price per share lower than the then-current conversion price; provided, however, that in no event shall the conversion price per common share be less than $1.00.

The fair value of the derivative liability was recorded and shown separately under current liabilities. Changes in the fair value of the derivative liability were recorded in the consolidated statement of operations under other income (expense).

The Company evaluates all of its agreements to determine if such instruments have derivatives or contain features that qualify as embedded derivatives. For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value and is then re-valued at each reporting date, with changes in the fair value reported in the consolidated statements of operations. For stock-based derivative financial instruments, the Company uses a weighted average Black-Scholes-Merton option pricing model to value the derivative instruments at inception and on subsequent valuation dates. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is evaluated at the end of each reporting period. Derivative instrument liabilities are classified in the balance sheet as current or non-current based on whether or not net-cash settlement of the derivative instrument could be required within 12 months of the balance sheet date.

The range of significant assumptions which the Company used to measure the fair value of the derivative liability at September 30, 2014 was as follows:

The February 2014 convertible note was repaid during the year ended September 30, 2015; therefore there was not a related derivative liability at September 30, 2015. There were no new derivative liabilities for year ended September 30, 2016.
