&lt;font style="FONT-FAMILY: 'Times New Roman'" size="2"&gt;The
preparation of financial statements in conformity with accounting
principles generally accepted in the United States requires
management to make estimates and assumptions that affect the
reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during
the reporting period. On an ongoing basis, the Company evaluates
its estimates, including those related to revenue recognition,
allowance for doubtful accounts, income taxes, stock-based
compensation expense, accrued liabilities, useful lives of property
and equipment and capitalized software development costs, among
others. The Company bases its estimates on historical experience
and on various other assumptions that are believed to be reasonable
under the circumstances, the results of which form the basis for
making judgments about the carrying values of assets and
liabilities that are not readily apparent from other sources.
Actual results could differ from the estimates made by management
with respect to these items.&lt;/font&gt;&lt;/p&gt;

&lt;font style="FONT-FAMILY: 'Times New Roman'" size="2"&gt;&lt;b&gt;&lt;i&gt;Foreign
Currency Translation&lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;font style="FONT-FAMILY: 'Times New Roman'" size="2"&gt;The U.S.
dollar is the reporting currency for all periods presented. The
functional currency of the Company&amp;#x2019;s foreign subsidiaries is
generally the local currency. All assets and liabilities
denominated in a foreign currency are translated into U.S. dollars
at the exchange rate on the balance sheet date. Revenue and
expenses are translated at the average rate during the period.
Equity transactions are translated using historical exchange rates.
Adjustments resulting from translating foreign currency financial
statements into U.S. dollars are included in accumulated other
comprehensive loss. Foreign currency transaction gains and losses
are included in net loss for the period. The Company recognized net
foreign currency gains(losses) of $0.4 million, $(0.4) million and
$0.2&amp;#xA0;million for fiscal years 2013, 2012 and 2011,
respectively.&lt;/font&gt;&lt;/p&gt;

&lt;font style="FONT-FAMILY: 'Times New Roman'" size="2"&gt;As a result
of the Company&amp;#x2019;s international operations, it is exposed to
various market risks that may affect its consolidated results of
operations, cash flows and financial position. These market risks
include, but are not limited to, fluctuations in currency exchange
rates. The Company&amp;#x2019;s primary foreign currency exposures are
in Euros and British Pound Sterling. The Company faces exposure to
adverse movements in currency exchange rates as the financial
results of certain of its operations are translated from local
currency into U.S. dollars upon consolidation. Additionally,
foreign exchange rate fluctuations on transactions denominated in
currencies other than the functional currency result in gains and
losses that are reflected in income.&lt;/font&gt;&lt;/p&gt;
&lt;p style="TEXT-TRANSFORM: none; MARGIN-TOP: 12px; TEXT-INDENT: 4%; LETTER-SPACING: normal; FONT: medium 'Times New Roman'; WHITE-SPACE: normal; MARGIN-BOTTOM: 0px; COLOR: rgb(0,0,0); WORD-SPACING: 0px; -webkit-text-stroke-width: 0px"&gt;
&lt;font style="FONT-FAMILY: 'Times New Roman'" size="2"&gt;The Company
may enter into derivative instruments to hedge certain net
exposures of non-U.S. dollar-denominated assets and liabilities,
even though it does not elect to apply hedge accounting or hedge
accounting does not apply. Gains and losses resulting from a change
in fair value of these derivatives are reflected in income in the
period in which the change occurs and are recognized on the
consolidated statement of operations in other income (expense).
Cash flows from these contracts are classified within net cash used
in operating activities on the consolidated statements of cash
flows.&lt;/font&gt;&lt;/p&gt;
&lt;p style="TEXT-TRANSFORM: none; MARGIN-TOP: 12px; TEXT-INDENT: 4%; LETTER-SPACING: normal; FONT: medium 'Times New Roman'; WHITE-SPACE: normal; MARGIN-BOTTOM: 0px; COLOR: rgb(0,0,0); WORD-SPACING: 0px; -webkit-text-stroke-width: 0px"&gt;
&lt;font style="FONT-FAMILY: 'Times New Roman'" size="2"&gt;The Company
does not use financial instruments for trading or speculative
purposes. The Company recognizes all derivative instruments on the
balance sheet at fair value, and its derivative instruments are
generally short-term in duration.&lt;/font&gt;&lt;/p&gt;
&lt;p style="TEXT-TRANSFORM: none; MARGIN-TOP: 12px; TEXT-INDENT: 4%; LETTER-SPACING: normal; FONT: medium 'Times New Roman'; WHITE-SPACE: normal; MARGIN-BOTTOM: 0px; COLOR: rgb(0,0,0); WORD-SPACING: 0px; -webkit-text-stroke-width: 0px"&gt;
&lt;font style="FONT-FAMILY: 'Times New Roman'" size="2"&gt;Derivative
contracts were not material as of April 30, 2013 and 2012. The
Company is exposed to the risk that counterparties to derivative
contracts may fail to meet their contractual
obligations.&lt;/font&gt;&lt;/p&gt;
&lt;p style="TEXT-TRANSFORM: none; MARGIN-TOP: 18px; TEXT-INDENT: 0px; LETTER-SPACING: normal; FONT: medium 'Times New Roman'; WHITE-SPACE: normal; MARGIN-BOTTOM: 0px; COLOR: rgb(0,0,0); MARGIN-LEFT: 63px; WORD-SPACING: 0px; -webkit-text-stroke-width: 0px"&gt;

&lt;font style="FONT-FAMILY: 'Times New Roman'" size="2"&gt;The carrying
amounts of the Company&amp;#x2019;s financial instruments, including
cash equivalents, accounts receivable, accounts payable and accrued
liabilities, approximate their respective fair values, due to the
short-term nature of the instruments.&lt;/font&gt;&lt;/p&gt;

&lt;font style="FONT-FAMILY: 'Times New Roman'" size="2"&gt;The Company
applies the authoritative guidance on fair value measurements for
financial assets and liabilities. The guidance defines fair value,
thereby eliminating inconsistencies in guidance found in various
prior accounting pronouncements, and increases disclosures
surrounding fair value calculations. The guidance establishes a
three-tiered fair value hierarchy that prioritizes inputs to
valuation techniques used in fair value calculations. The three
levels of inputs are defined as follows:&lt;/font&gt;&lt;/p&gt;
&lt;p style="TEXT-TRANSFORM: none; MARGIN-TOP: 18px; TEXT-INDENT: 0px; LETTER-SPACING: normal; FONT: medium 'Times New Roman'; WHITE-SPACE: normal; MARGIN-BOTTOM: 0px; COLOR: rgb(0,0,0); WORD-SPACING: 0px; -webkit-text-stroke-width: 0px"&gt;
&lt;font style="FONT-FAMILY: 'Times New Roman'" size="2"&gt;Level 1:

&lt;font style="FONT-FAMILY: 'Times New Roman'" size="2"&gt;Level 2:
Inputs that are observable in the marketplace other than those
inputs classified as Level 1.&lt;/font&gt;&lt;/p&gt;
&lt;p style="TEXT-TRANSFORM: none; MARGIN-TOP: 6px; TEXT-INDENT: 0px; LETTER-SPACING: normal; FONT: medium 'Times New Roman'; WHITE-SPACE: normal; MARGIN-BOTTOM: 0px; COLOR: rgb(0,0,0); WORD-SPACING: 0px; -webkit-text-stroke-width: 0px"&gt;
&lt;font style="FONT-FAMILY: 'Times New Roman'" size="2"&gt;Level 3:
Inputs that are unobservable in the marketplace which require the
Company to develop its own assumptions.&lt;/font&gt;&lt;/p&gt;
&lt;p style="TEXT-TRANSFORM: none; MARGIN-TOP: 18px; TEXT-INDENT: 0px; LETTER-SPACING: normal; FONT: medium 'Times New Roman'; WHITE-SPACE: normal; MARGIN-BOTTOM: 0px; COLOR: rgb(0,0,0); MARGIN-LEFT: 63px; WORD-SPACING: 0px; -webkit-text-stroke-width: 0px"&gt;
&lt;font style="FONT-FAMILY: 'Times New Roman'" size="2"&gt;&lt;b&gt;&lt;i&gt;Cash

&lt;font style="FONT-FAMILY: 'Times New Roman'" size="2"&gt;The Company
considers all highly liquid investments acquired with an original
maturity of three months or less at the date of purchase and
readily convertible to known amounts of cash to be cash
equivalents. Cash and cash equivalents are deposited with banks in
demand deposit accounts. Cash equivalents are stated at cost, which
approximates market value, because of the short maturity of these
instruments.&lt;/font&gt;&lt;/p&gt;
&lt;p style="TEXT-TRANSFORM: none; MARGIN-TOP: 18px; TEXT-INDENT: 0px; LETTER-SPACING: normal; FONT: medium 'Times New Roman'; WHITE-SPACE: normal; MARGIN-BOTTOM: 0px; COLOR: rgb(0,0,0); MARGIN-LEFT: 63px; WORD-SPACING: 0px; -webkit-text-stroke-width: 0px"&gt;
&lt;font style="FONT-FAMILY: 'Times New Roman'" size="2"&gt;&lt;b&gt;&lt;i&gt;Short-term Investments&lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="TEXT-TRANSFORM: none; MARGIN-TOP: 6px; TEXT-INDENT: 4%; LETTER-SPACING: normal; FONT: medium 'Times New Roman'; WHITE-SPACE: normal; MARGIN-BOTTOM: 0px; COLOR: rgb(0,0,0); WORD-SPACING: 0px; -webkit-text-stroke-width: 0px"&gt;
&lt;font style="FONT-FAMILY: 'Times New Roman'" size="2"&gt;Short-term
investments consist of U.S. treasury securities and agency
securities that are a guaranteed obligation of the U.S. Government
and are classified as available-for-sale securities. The Company
may or may not hold securities with stated maturities greater than
one year until maturity. After consideration of its risks versus
reward objectives, as well as its liquidity requirements, the
Company may sell these securities prior to their stated maturities.
As the Company views these securities as available to support
current operations, it has classified all available-for-sale
securities as short-term. Available-for-sale securities are carried
at fair value with unrealized gains and losses reported as a
component of accumulated other comprehensive income (loss) in
stockholders&amp;#x2019; equity. For the periods presented, realized and
unrealized gains and losses on investments were not material. An
impairment charge is recorded in the consolidated statements of
operations for declines in fair value below the cost of an
individual investment that are deemed to be other-than-temporary.
The Company assesses whether a decline in value is temporary based
on the length of time that the fair market value has been below
cost, the severity of the decline, as well as the intent and
ability to hold, or plans to sell, the investment. There have been
no impairment charges recognized related to short-term investments
for the fiscal years ended April&amp;#xA0;30, 2013, 2012 or
2011.&lt;/font&gt;&lt;/p&gt;

&lt;font style="FONT-FAMILY: 'Times New Roman'" size="2"&gt;The
Company&amp;#x2019;s restricted cash consists of a standby letter of
credit under its Pledge and Security Agreement for corporate credit
card services, secured by its money market account. (see Note

&lt;font style="FONT-FAMILY: 'Times New Roman'" size="2"&gt;Accounts
receivable represent trade receivables from clients for whom the
Company has provided services and not yet received payment. The
Company presents accounts receivable net of an allowance for
doubtful accounts. The Company maintains an allowance for doubtful
accounts for estimated losses resulting from the inability of
clients to make required payments. In estimating this allowance,
the Company considers factors such as: historical collection
experience, a client&amp;#x2019;s current credit-worthiness, client
concentrations, age of the receivable balance, both individually
and in the aggregate, and general economic conditions that may
affect a client&amp;#x2019;s ability to pay. Any change in the
assumptions used in analyzing a specific account receivable might
result in an additional allowance for doubtful accounts being
recognized in the period in which the change occurs.&lt;/font&gt;&lt;/p&gt;

&lt;font style="FONT-FAMILY: 'Times New Roman'" size="2"&gt;The allowance
for doubtful accounts was $2.7 million and $0.8 million at
April&amp;#xA0;30, 2013 and 2012, respectively.&lt;/font&gt;&lt;/p&gt;

&lt;font style="FONT-FAMILY: 'Times New Roman'" size="2"&gt;Financial
instruments that potentially subject the Company to concentrations
of credit risk consist of cash and cash equivalents, and trade
receivables. The Company&amp;#x2019;s cash and cash equivalents are
placed with high-credit-quality financial institutions and issuers,
and at times exceed federally insured limits. The Company has not
experienced any loss relating to cash and cash equivalents in these
accounts. The Company performs periodic credit evaluations of its
clients and generally does not require collateral.&lt;/font&gt;&lt;/p&gt;

&lt;font style="FONT-FAMILY: 'Times New Roman'" size="2"&gt;The Company
capitalizes certain development costs incurred in connection with
its internal-use software. These capitalized costs are primarily
related to its proprietary social commerce platform that is hosted
by the Company and accessed by its clients on a subscription basis.
Costs incurred in the preliminary stages of development are
expensed as incurred. Once an application has reached the
development stage, direct internal and external costs are
capitalized until the software is substantially complete and ready
for its intended use. Maintenance and training costs are expensed
as incurred. Internal-use software development costs are amortized
on a straight-line basis over its estimated useful life, generally
three years, into cost of revenue.&lt;/font&gt;&lt;/p&gt;

&lt;font style="FONT-FAMILY: 'Times New Roman'" size="2"&gt;The Company
evaluates and tests the recoverability of its goodwill for
impairment at least annually during the fourth quarter or more
often if and when circumstances indicate that goodwill may not be
recoverable.&lt;/font&gt;&lt;/p&gt;

&lt;font style="FONT-FAMILY: 'Times New Roman'" size="2"&gt;Intangible
assets are amortized over their useful lives. Each period the
Company evaluates the estimated remaining useful life of its
intangible assets and whether events or changes in circumstances
warrant a revision to the remaining period of amortization. The
carrying amounts of these assets are periodically reviewed for
impairment whenever events or changes in circumstances indicate
that the carrying value of these assets may not be recoverable.
Recoverability of these assets is measured by comparison of the
carrying amount of each asset to the future undiscounted cash flows
the asset is expected to generate. If the undiscounted cash flows
used in the test for recoverability are less than the carrying
amount of these assets then the Company will recognize an
impairment charge.&lt;/font&gt;&lt;/p&gt;

&lt;font style="FONT-FAMILY: 'Times New Roman'" size="2"&gt;The Company
evaluates the recoverability of its long-lived assets for possible
impairment whenever events or circumstances indicate that the
carrying amount of such assets may not be recoverable. If such
review indicates that the carrying amount of long-lived assets is
not recoverable, the carrying amount of such assets is reduced to
fair value.&lt;/font&gt;&lt;/p&gt;

&lt;font style="FONT-FAMILY: 'Times New Roman'" size="2"&gt;The Company
generates SaaS revenue principally from the sale of subscriptions
to its hosted social commerce platform and sells its application
services pursuant to service agreements that are generally one year
in length. The client does not have the right to take possession of
the software supporting the application service at any time, nor do
the arrangements contain general rights of return. The Company
accounts for these arrangements by recognizing the arrangement
consideration for the application service ratably over the term of
the related agreement, commencing upon the later of the agreement
start date or when all revenue recognition criteria have been
met.&lt;/font&gt;&lt;/p&gt;

&lt;font style="FONT-FAMILY: 'Times New Roman'" size="2"&gt;Media revenue
consists primarily of fees charged to advertisers when their
advertisements are displayed on websites owned by various
third-parties (&amp;#x201C;Publishers&amp;#x201D;). The Company has revenue
sharing agreements with these Publishers. The Company receives a
fee from the advertisers and pays the Publishers based on their
contractual revenue-share. Media revenues earned from the
advertisers are recognized on a net basis as the Company has
determined that it is acting as an agent in these
transactions.&lt;/font&gt;&lt;/p&gt;

&lt;font style="FONT-FAMILY: 'Times New Roman'" size="2"&gt;Deferred
revenue consists of billings or payments in advance of revenue
recognition and is recognized as revenue recognition criteria are
met. The Company invoices clients in a variety of installments and,
consequently, the deferred revenue balance does not represent the
total contract value of its non-cancelable subscription agreements.
Deferred revenue that will be recognized during the succeeding 12
month period is recorded as current deferred revenue and the
remaining portion is recorded as non-current deferred
revenue.&lt;/font&gt;&lt;/p&gt;

records stock-based compensation expense based upon the fair value
for all stock options issued to all persons to the extent that such
options vest. The fair value of each award is calculated by the
Black-Scholes option pricing model. The Company recognizes
stock-based expense on a straight-line basis over the respective
vesting period. The Company recognizes stock-based expense for
shares issued pursuant to its Employee Stock Purchase Plan
(&amp;#x201C;ESPP&amp;#x201D;) on a straight-line basis over the offering
period of six months. The Company includes an estimated effect of
forfeitures in its compensation cost and updates the estimated
forfeiture rate through the final vesting date of the awards.
Stock-based expense was $22.5 million, $7.7&amp;#xA0;million and $4.7
million for the years ended April&amp;#xA0;30, 2013, 2012 and 2011,

&lt;font style="FONT-FAMILY: 'Times New Roman'" size="2"&gt;The Company
currently recognizes an insignificant tax benefit resulting from
compensation costs expensed in the financial statements, however
the Company provides a valuation allowance against the majority of

&lt;font style="FONT-FAMILY: 'Times New Roman'" size="2"&gt;The Company
uses the liability method of accounting for income taxes. Under
this method, deferred tax assets and liabilities are recognized for
the expected future tax consequences of temporary differences
between the carrying amounts and the tax bases of assets and
liabilities. Deferred tax assets and liabilities are measured using
enacted tax rates expected to apply to taxable income in the years
in which those temporary differences are expected to be recovered
or settled. The effect of a change in tax rates on deferred tax
assets and liabilities will be recognized in the period that
includes the enactment date. A valuation allowance is established
against the deferred tax assets to reduce their carrying value to
an amount that is more likely than not to be realized.&lt;/font&gt;&lt;/p&gt;

&lt;font style="FONT-FAMILY: 'Times New Roman'" size="2"&gt;The Company
computes basic earnings per share available to common stockholders
by dividing net income available to common stockholders by the
weighted average number of common shares outstanding during the
reporting period. The Company computes diluted earnings per share
similarly to basic earnings per share except that it reflects the
potential dilution that could occur if dilutive securities or other
obligations to issue common stock were exercised or converted into
common stock. As the Company has only incurred losses to date,
diluted earnings per share is the same as basic earnings per
share.&lt;/font&gt;&lt;/p&gt;

&lt;font style="FONT-FAMILY: 'Times New Roman'" size="2"&gt;In June 2011,
the FASB issued a standard to require an entity to present the
total of comprehensive income, the components of net income and the
components of other comprehensive income either in a single
continuous statement of comprehensive income or in two separate but
consecutive statements. The standard eliminates the option to
present the components of other comprehensive income as part of the
statement of equity. The updated accounting guidance is effective
for fiscal years, and interim periods within those years, beginning
after December&amp;#xA0;15, 2011 on a retrospective basis. Early
application is permitted. The Company adopted the updated guidance
in the first quarter of the fiscal year ending April&amp;#xA0;30,
2013.&lt;/font&gt;&lt;/p&gt;

&lt;font style="FONT-FAMILY: 'Times New Roman'" size="2"&gt;In February
2013, the FASB issued an update to improve the reporting of
reclassifications out of accumulated other comprehensive income
(&amp;#x201C;AOCI&amp;#x201D;). Companies are also required to present
reclassifications by component when reporting changes in AOCI
balances. The updated accounting guidance is effective for fiscal
years, and interim periods within those years, beginning after
December&amp;#xA0;15, 2012 on a prospective basis. This guidance will
be effective for the fiscal year ending April&amp;#xA0;30, 2014 and is
not expected to have a material impact on the Company&amp;#x2019;s
consolidated financial statements.&lt;/font&gt;&lt;/p&gt;

&lt;font style="FONT-FAMILY: 'Times New Roman'" size="2"&gt;In March
2013, the FASB issued Accounting Standard Update 2013-05,
&amp;#x201C;Parent&amp;#x2019;s Accounting for the Cumulative Translation
Adjustment upon Derecognition of Certain Subsidiaries or Groups of
Assets within a Foreign Entity or of an Investment in a Foreign
Entity,&amp;#x201D; (&amp;#x2018;ASU 2013-05&amp;#x2019;) to address diversity in
practice related to the release of cumulative translation
adjustments (&amp;#x201C;CTA&amp;#x201D;) into earnings upon the occurrence
of certain derecognition events. This guidance will be effective
for the fiscal year ending April 30, 2014 and is not expected to
have a material impact on the Company&amp;#x2019;s consolidated
financial statements.&lt;/font&gt;&lt;/p&gt;
