STOCK-BASED COMPENSATION |
In
connection with the Acquisition, the Company assumed options to
purchase 49,159 shares of common stock at exercise prices ranging
from $1.53 to $1,072.53.
Following
the Acquisition, option grants to directors and employees will be
made under the Novelos Therapeutics 2006 Stock Incentive Plan (the
“2006 Plan”). On May 18, 2011, the Board of
Directors approved certain amendments to the 2006 Plan and on June
30, 2011, the Company’s stockholders ratified those
amendments. A total of 7,000,000 shares of common stock
are reserved for issuance under the 2006 Plan for grants of
incentive or nonqualified stock options, rights to purchase
restricted and unrestricted shares of common stock, stock
appreciation rights and performance share grants. A
committee of the board of directors determines exercise prices,
vesting periods and any performance requirements on the date of
grant, subject to the provisions of the 2006
Plan. Options are granted at or above the fair market
value of the common stock at the grant date and expire on the tenth
anniversary of the grant date. Vesting periods are
generally between one and four years. Options granted
pursuant to the 2006 Plan generally will become fully vested upon a
termination event occurring within one year following a change in
control, as defined. A termination event is defined as
either termination of employment or services other than for cause
or constructive termination of employees or consultants resulting
from a significant reduction in either the nature or scope of
duties and responsibilities, a reduction in compensation or a
required relocation. As of September 30, 2011, there are
an aggregate of 3,476,112 shares available for grant under the 2006
Plan.
The
following table summarizes amounts charged to expense for
stock-based compensation related to employee and director stock
option grants and stock-based compensation recorded in connection
with stock options granted to non-employee
consultants:
On
May 18, 2011, the Company cancelled 100,000 options originally
granted on April 25, 2011 with an exercise price of $3.00 per share
and issued 100,000 replacement stock option awards with an exercise
price of $1.40. The cancellation and replacement
constituted a modification to the terms of the award and additional
stock-based compensation was measured as the excess of the fair
value of the modified award over the fair value of the original
award immediately before the modification. Accordingly,
incremental stock-based compensation expense of $4,494 was recorded
during the second quarter of 2011 in connection with the
modification.
The
Company granted 3,496,400 stock options to employees and
non-employees during the nine months ended September 30, 2011 under
the 2006 Plan. The Company issued options to
purchase a total of 200,000 shares of common stock to non-employees
outside of any formalized plan, but 100,000 were forfeited as a
result of the cancellation and replacement as described
above. Exercise prices for all grants of options to
purchase common stock made during the nine months ended September
30, 2011 were equal to the market value of the Company’s
common stock on the date of grant.
Assumptions Used In Determining Fair Value
Valuation and amortization method. The fair value of each
stock award is estimated on the grant date using the Black-Scholes
option-pricing model. The estimated fair value of
employee stock options is amortized to expense using the
straight-line method over the vesting period. The
estimated fair value of the non-employee options is amortized to
expense over the period during which a non-employee is required to
provide services for the award (usually the vesting
period).
Volatility. The Company estimates volatility based on an
average of (1) the Company’s historical volatility since its
common stock has been publicly traded and (2) review of volatility
estimates of publicly held drug development companies with similar
market capitalizations. The Company utilizes this
average approach since its historical volatility would not
necessarily be indicative of its expected future volatility due to
the significant change in the stage of development that occurred in
connection with the Acquisition.
Risk-free interest rate. The risk-free interest rate is
based on the U.S. Treasury yield curve in effect at the time of
grant commensurate with the expected term assumptions for the
option awards.
Expected term. The expected term of stock options granted is
based on an estimate of when options will be exercised in the
future. As the Company has had a significant change in
its business operations as result of the Acquisition and the
historical experience is not indicative of the expected behavior in
the future, the Company applied the simplified method of estimating
the expected term of the options. The expected term,
calculated under the simplified method, is applied to groups of
stock options that have similar contractual terms. Using
this method, the expected term is determined using the average of
the vesting period and the contractual life of the stock options
granted. The Company applied the simplified method to
non-employees who have a truncation of term based on termination of
service and utilizes the contractual life of the stock options
granted for those non-employee grants which do not have a
truncation of service.
Forfeitures. Stock-based compensation
expense is recorded only for those awards that are expected to
vest. FASB ASC Topic 718 requires forfeitures to be
estimated at the time of grant and revised, if necessary, in
subsequent periods if actual forfeitures differ from those
estimates. The term “forfeitures” is
distinct from “cancellations” or
“expirations” and represents only the unvested portion
of the surrendered option. An annual forfeiture rate of
0% was applied to all unvested options as of September 30, 2011 as
the historical experience of forfeitures is not representative of
expected future forfeiture rates as a result of the significant
changes in the business operations as a result of the
Acquisition. This analysis will be re-evaluated
semi-annually and the forfeiture rate will be adjusted as
necessary. Ultimately, the actual expense recognized
over the vesting period will be for only those shares that
vest.
The
following table summarizes weighted-average values and assumptions
used for options granted to employees, directors and consultants in
the periods indicated:
There
were no options granted during the three months ended September 30,
2011 or during the three or nine months ended September 30,
2010.
A
summary of stock option activity under stock option plans for the
nine months ended September 30, 2011 is as follows:
The
aggregate intrinsic value of options outstanding is calculated
based on the positive difference between the closing market price
of the Company’s common stock at the end of the respective
period and the exercise price of the underlying
options. There were no options exercised during the nine
months ended September 30, 2011. Shares of common stock issued upon
the exercise of options are from authorized but unissued
shares.
As
of September 30, 2011, there was $2,728,294 of total unrecognized
compensation cost related to unvested stock-based compensation
arrangements. Of this total amount, the Company expects
to recognize $281,357, $1,125,400, $858,452, $387,397 and $75,688
during 2011, 2012, 2013, 2014 and 2015,
respectively. The Company expects 3,299,953 of unvested
options to vest in the future. The weighted-average
grant-date fair value of vested and unvested options outstanding at
September 30, 2011 was $1.44 and $1.17, respectively.
On
October 6, 2011, the Company granted 70,000 stock options with an
exercise price of $1.05, which was equal to the closing price of
the Company’s common stock on the date of grant, to a
non-employee in exchange for certain consulting
services. The grant-date fair value using the
Black-Scholes option pricing model was $0.85 per share, or
$59,500.
