Our equity compensation plans provide for the grant of incentive
and nonqualified stock options, as well as other stock-based awards
including restricted stock, restricted stock units and performance
share units, to employees, non-employee directors and other
consultants who provide services to us. Restricted stock awards
result in the issuance of new shares when granted. For other
stock-based awards, new shares are issued when the award is
exercised, vested or released according to the terms of the
agreement. In February 2017, 1,024,868 additional shares were
reserved for future issuance under our 2010 Equity Incentive Plan.
As of March 31, 2017, there were approximately
4.5 million shares available for grant under approved equity
compensation plans.</p>

Our employee stock purchase plan allows participating employees to
purchase shares of our common stock at a discount through payroll
deductions. The plan is available to all employees subject to
certain eligibility requirements. Participating employees may
purchase common stock, on a voluntary after tax basis, at a price
that is the lower of 85% of the fair market value of one share of
common stock at the beginning or end of each stock purchase period.
The plan consists of two six-month offering periods, beginning on
January 1 and July 1 of each calendar year, respectively.
A total of 1.1 million shares of common stock are reserved for
issuance under the plan.</p>

We record our interim provision for income taxes by applying our
estimated annual effective tax rate to our year-to-date pretax
income and adjust the provision for discrete tax items recorded in
the period. Differences between our effective tax rate and
statutory tax rates are primarily due to the impact of permanently
non-deductible expenses partially offset by the federal research
and development credit. Additionally, under ASU 2016-09, excess tax
benefits generated upon settlement or exercise of stock awards are
now recognized as a reduction to income tax expense as a discrete
tax item in the quarter that the event occurs creating potentially
significant fluctuation in tax expense by quarter and by year. Our
provisions for income taxes included current federal, foreign and
state income tax expense, as well as deferred tax expense.</p>

<i>Recently Adopted Accounting Pronouncements</i></p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
In March 2016, the Financial Accounting Standards Board
(“FASB”) issued ASU 2016-09, <i>Improvements to
Employee Share-Based Payment Accounting</i> (“ASU
2016-09”). The new guidance requires excess tax benefits and
tax deficiencies to be recorded in the income statement when the
awards vest or are settled and provides an accounting policy
election to account for forfeitures as they occur. In addition,
cash flows related to excess tax benefits will no longer be
separately classified as a financing activity apart from other
income tax cash flows within operating activities. The standard
also allows entities to repurchase more of an employee’s
shares for tax withholding purposes without triggering liability
accounting and clarifies that all cash payments made on an
employee’s behalf for withheld shares should be presented as
a financing activity on the statements of cash flows. The standard
is effective for fiscal years, and interim periods within those
fiscal years, beginning after December 15, 2016, with early
adoption permitted.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
We adopted ASU 2016-09 during the three months ended March 31,
2017. The impact to our consolidated balance sheet as of
January 1, 2017 was a $16.3 million increase in deferred
income tax assets, non-current and a corresponding $16.3 million
decrease in accumulated deficit. This impact results from the
cumulative-effect adjustment for previously unrecognized excess tax
benefits using the modified retrospective method required by the
new standard. We elected to adopt the changes in cash flow
statement presentation prospectively to be consistent with the
prospective transition for the treatment of excess tax benefits in
the income statement. Accordingly, we no longer classify excess tax
benefits as a financing activity subsequent to January 1,
2017.</p>

<i>Recently Issued Accounting Pronouncements</i></p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
In May 2014, the FASB issued Accounting Standards Update
No. 2014-09, <i>Revenue from Contracts with Customers (Topic
606)</i>, which requires an entity to recognize the amount of
revenue to which it expects to be entitled for the transfer of
promised goods or services to customers in an amount that reflects
the consideration to which the entity expects to be entitled in
exchange for those goods or services. This guidance will replace
most existing revenue recognition guidance in GAAP when it becomes
effective. These new requirements are effective for annual
reporting periods beginning after December 15, 2017, and
interim periods within those annual periods. We do not believe the
new revenue recognition standard will materially impact our
recognition of the primary fees received from customers for our
cloud-based supply chain solutions. We believe the adoption of the
new standard could impact our accounting for certain upfront set-up
fees and the periods over which the related revenues are
recognized, as well as the timing of cost recognition for sales
commissions and other contract acquisition costs. We are currently
evaluating implementation methods and the extent of the impact that
implementation of this standard will have on our consolidated
financial statements upon adoption</p>

In February 2016, the FASB issued ASU 2016-02, <i>Leases</i> which
will supersede the existing lease guidance and will require all
leases with a term greater than 12 months to be recognized in the
statements of financial position and eliminate current real
estate-specific lease guidance, while maintaining substantially
similar classification criteria for distinguishing between finance
leases and operating leases. This standard is effective for fiscal
years, and interim periods within those fiscal years, beginning
after December 15, 2018, with early adoption permitted. We
believe the adoption of the new lease accounting standard will
materially impact our consolidated financial statements by
increasing our non-current assets and non-current liabilities on
our consolidated balance sheets in order to record the right of use

<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
We invest primarily in money market funds, highly liquid debt
instruments of the U.S. government, and U.S. corporate debt
securities. All highly liquid investments with original maturities
of 90 days or less are classified as cash equivalents. All
investments with original maturities greater than 90 days and
remaining maturities less than one year from the balance sheet date
are classified as short-term marketable securities. Investments
with remaining maturities of more than one year from the balance
sheet date are classified as marketable securities, non-current.
Short-term marketable securities and marketable securities,
non-current, are also classified as available-for-sale. We intend
to hold marketable securities until maturity; however, we may sell
these securities at any time for use in current operations or for
other purposes. Consequently, we may or may not keep securities
with stated holding periods to maturity.</p>

Our fixed income investments are carried at fair value and
unrealized gains and losses on these investments are included in
other comprehensive income (loss) in the condensed consolidated
statements of comprehensive income (loss). Realized gains or losses
are included in other income (expense) in the condensed
consolidated statements of comprehensive income (loss). When a
determination has been made that an other-than-temporary decline in
fair value has occurred, the amount of the decline that is related
to a credit loss is realized and is included in other income
(expense), net in the condensed consolidated statements of
comprehensive income (loss).</p>

the use of observable inputs and minimize the use of unobservable
inputs when measuring fair value. A financial instrument’s
categorization within the fair value hierarchy is based upon the
lowest level of input that is significant to the fair value
measurement. The three levels of inputs that may be used to measure
fair value are:</p>

The accompanying unaudited condensed consolidated financial

subsidiaries. All intercompany accounts and transactions have been
eliminated in the condensed consolidated financial statements,
which have been prepared in conformity with U.S. generally accepted
accounting principles (“GAAP”) for interim financial
information and with the instructions to Form 10-Q and Rule 10-01
of Regulation S-X. Accordingly, these condensed consolidated
financial statements do not include all of the information and
notes required by GAAP. We have included all normal recurring
adjustments considered necessary to give a fair statement of our
financial position, results of operations and cash flows for the
interim periods shown. Operating results for these interim periods
are not necessarily indicative of the results to be expected for
the full year. The December 31, 2016 condensed consolidated
balance sheet data was derived from our audited financial
statements at that date. For further information, refer to the
consolidated financial statements and accompanying notes for the
year ended December 31, 2016 included in our Annual Report on

In March 2016, the Financial Accounting Standards Board
(“FASB”) issued ASU 2016-09, <i>Improvements to
Employee Share-Based Payment Accounting</i> (“ASU
2016-09”). The new guidance requires excess tax benefits and
tax deficiencies to be recorded in the income statement when the
awards vest or are settled and provides an accounting policy
election to account for forfeitures as they occur. In addition,
cash flows related to excess tax benefits will no longer be
separately classified as a financing activity apart from other
income tax cash flows within operating activities. The standard
also allows entities to repurchase more of an employee’s
shares for tax withholding purposes without triggering liability
accounting and clarifies that all cash payments made on an
employee’s behalf for withheld shares should be presented as
a financing activity on the statements of cash flows. The standard
is effective for fiscal years, and interim periods within those
fiscal years, beginning after December 15, 2016, with early
adoption permitted.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
We adopted ASU 2016-09 during the three months ended March 31,
2017. The impact to our consolidated balance sheet as of
January 1, 2017 was a $16.3 million increase in deferred
income tax assets, non-current and a corresponding $16.3 million
decrease in accumulated deficit. This impact results from the
cumulative-effect adjustment for previously unrecognized excess tax
benefits using the modified retrospective method required by the
new standard. We elected to adopt the changes in cash flow
statement presentation prospectively to be consistent with the
prospective transition for the treatment of excess tax benefits in
the income statement. Accordingly, we no longer classify excess tax
benefits as a financing activity subsequent to January 1,
2017.</p>

<i>Recently Issued Accounting Pronouncements</i></p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
In May 2014, the FASB issued Accounting Standards Update
No. 2014-09, <i>Revenue from Contracts with Customers (Topic
606)</i>, which requires an entity to recognize the amount of
revenue to which it expects to be entitled for the transfer of
promised goods or services to customers in an amount that reflects
the consideration to which the entity expects to be entitled in
exchange for those goods or services. This guidance will replace
most existing revenue recognition guidance in GAAP when it becomes
effective. These new requirements are effective for annual
reporting periods beginning after December 15, 2017, and
interim periods within those annual periods. We do not believe the
new revenue recognition standard will materially impact our
recognition of the primary fees received from customers for our
cloud-based supply chain solutions. We believe the adoption of the
new standard could impact our accounting for certain upfront set-up
fees and the periods over which the related revenues are
recognized, as well as the timing of cost recognition for sales
commissions and other contract acquisition costs. We are currently
evaluating implementation methods and the extent of the impact that
implementation of this standard will have on our consolidated
financial statements upon adoption</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
In February 2016, the FASB issued ASU 2016-02, <i>Leases</i> which
will supersede the existing lease guidance and will require all
leases with a term greater than 12 months to be recognized in the
statements of financial position and eliminate current real
estate-specific lease guidance, while maintaining substantially
similar classification criteria for distinguishing between finance
leases and operating leases. This standard is effective for fiscal
years, and interim periods within those fiscal years, beginning
after December 15, 2018, with early adoption permitted. We
believe the adoption of the new lease accounting standard will
materially impact our consolidated financial statements by
increasing our non-current assets and non-current liabilities on
our consolidated balance sheets in order to record the right of use
assets and related lease liabilities for our existing operating
leases. We are in the process of determining the financial
statement impact and are currently unable to estimate the impact on
our consolidated financial statements.</p>
