Nature and Continuance of Operations

Stellar Biotechnologies, Inc. (“the Company”, formerly CAG Capital Inc.) is listed on the TSX Venture Exchange (‘the Exchange”) as a Tier 2 issuer under the trading symbol KLH since April 19, 2010 (formerly under CAG.P).

On April 7, 2010, the Company changed its name to Stellar Biotechnologies, Inc.  On April 12, 2010, the Company completed a reverse merger transaction with Stellar Biotechnologies, Inc. (“Stellar CA”) which is incorporated under the laws of the State of California, USA. The Company’s head office is 332 E. Scott Street, Port Hueneme, California, 93041, USA, and the registered office is 1868 King George Boulevard, South Surrey, BC, V4A 5A1, Canada.

The Company’s business is to commercially produce and market Keyhole Limpet Hemocyanin (“KLH”) as well as to develop new technology related to culture and production of KLH and subunit KLH (“suKLH”) formulations.  The Company markets KLH and suKLH formulations to customers in the United States and Europe.

The Company has received grants for the development of new technology from the National Institutes of Health, National Cancer Institute (“NIH”), the National Science Foundation (“NSF”) including grants under its Technology Enhancement for Commercial Partnerships (“TECP”) program, and Internal Revenue Service (“IRS”) qualifying therapeutic discovery project grants.

These condensed interim consolidated financial statements are prepared on a going concern basis.  The going concern basis contemplates that the Company will continue in operation for the foreseeable future and will be able to realize its assets and discharge its liabilities in the normal course of business.  Should the Company be required to realize the value of its assets in other than the ordinary course of business, the net realizable value of its assets may be materially less than the amounts shown in the condensed interim consolidated financial statements.  For the period ended February 29, 2012, the Company reported a loss of $1,552,961 (2011 - $9,209,011), an accumulated deficit of $8,457,015 (August 31, 2011 - $6,934,054; September 1, 2010 - $1,055,365) and working capital of $2,674,780 (August 31, 2011 - $4,061,980: September 1, 2010 - $2,174,121).  As at February 29, 2012, the Company has remaining revenues available under the NSF grants, including the Technology Enhancement for Commercial Partnerships (“TECP”) program of approximately $490,000.  The Company also anticipates ongoing contract income and commercial sales.

The financial statements of the Company are presented in US dollars, unless otherwise stated, which is the presentation currency.

Basis of Presentation and Adoption of IFRS

Statement of Compliance and Conversion to International Financial Reporting Standards

These unaudited condensed interim consolidated financial statements, including comparatives have been prepared using accounting policies consistent with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”) and Interpretations issued by the International Financial Reporting Interpretations Committee (“IFRIC”) and in accordance with International Accounting Standard (“IAS”) 34, Interim Financial Reporting.

The preparation of these condensed interim consolidated financial statements resulted in changes to the accounting policies as compared with the most recent annual financial statements prepared under Canadian Generally Accepted Accounting Principles (“Canadian GAAP”). The accounting policies set out below have

Notes to Consolidated Interim Consolidated Financial Statements

Basis of Presentation and Adoption of IFRS (continued)

been applied consistently to all periods presented in these condensed interim consolidated financial statements. They have also been applied in preparing an opening IFRS balance sheet as at September 1, 2010 for the purposes of the transition to IFRS, as required by IFRS 1, First Time Adoption of International Financial Reporting Standards (“IFRS 1”). The impact of the transition from Canadian GAAP to IFRS is explained in Note 15.

As these are the Company’s second condensed interim consolidated financial statements prepared in accordance with IFRS, the Company’s disclosures exceed the minimum requirements under IAS 34.  The Company has elected to exceed the minimum requirements in order to present the Company’s accounting policies in accordance with IFRS and the additional disclosures required under IFRS, which also highlight the changes from the Company’s August 31, 2011 annual consolidated financial statements prepared in accordance with Canadian GAAP.  In fiscal year August 31, 2013 and beyond, the Company may not provide the same amount of disclosure in the Company’s condensed interim consolidated financial statements under IFRS as the reader will be able to refer to the August 31, 2012 annual consolidated financial statements which will be prepared in accordance with IFRS.

Basis of Presentation

The condensed interim consolidated financial statements have been prepared on a historical cost basis, except for financial instruments classified as financial instruments at fair value through profit or loss, which are stated at their fair value. In addition, these financial statements have been prepared using the accrual basis of accounting except for cash flow information.

The preparation of these condensed interim consolidated financial statements requires management to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and reported amounts of expenses during the period. Actual results could differ from these estimates.

These condensed interim consolidated financial statements include estimates which, by their nature, are uncertain. The impacts of such estimates are pervasive throughout the condensed interim consolidated financial statements, and may require accounting adjustments based on future occurrences.  Revisions to accounting estimates are recognized in the period in which the estimate is revised and future periods if the revision affects both current and future periods. These estimates are based on historical experience, current and future economic conditions and other factors, including expectations of future events that are believed to be reasonable under the circumstances.

3.

Significant Accounting Policies

The accounting policies set out below are expected to be adopted for the year-ending August 31, 2012 and have been applied consistently to all periods presented in these condensed interim consolidated financial statements and in preparing the opening IFRS statement of financial position at September 1, 2010 for the purposes of the transition to IFRS, unless otherwise indicated.

a)

Principles of Consolidation

The condensed interim consolidated financial statements have been prepared in accordance with IFRS and include the accounts of the Company and its wholly-owned subsidiary Stellar Biotechnologies, Inc. (“Stellar CA”).  Intercompany balances and transactions are eliminated on consolidation.

Significant Accounting Policies (continued)

b)

Use of Estimates

The preparation of financial statements in conformity with IFRS 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 dates of the financial statements and the reported amounts of revenues and expenses during the reported periods. The Company has made estimates for allowance of doubtful accounts, amortization and depreciation and impairment of property, plant and equipment and licensing rights, share-based payments, research and development costs, biological assets, the provision for deferred income tax recoveries and composition of deferred income tax assets and liabilities, and accrued liabilities.  Actual results could differ from these estimates.

Significant assumptions about the future and other sources of estimated uncertainty that management has made at the financial position reporting date, that could result in a material adjustment to the carrying amounts of assets and liabilities, in the event that actual results differ from assumptions made, relate to, but are not limited to the following:

1)

the inputs used in the accounting for share-based payment expense included in profit or loss.

2)

the inputs used in accounting for biological assets included in statements of financial position and profit or loss.

3)

the determination of the useful life of the licensing rights.

4)

the inputs used in the accounting for the warrant liability.

c)

Earnings (Loss) Per Share

Basic earnings (loss) per share is calculated by dividing income available to common shareholders by the weighted average number of common shares outstanding during the period.

The computation of diluted loss per share assumes the conversion, exercise or contingent issuance of securities only when such conversion, exercise or issuance would have a dilutive effect on loss per share.  The dilutive effect of convertible securities is reflected in diluted earnings per share by application of the “if converted” method.  The dilutive effect of outstanding options and warrants and their equivalents is reflected in diluted earnings per share by application of the treasury stock method.

d)

Share-Based Payments

The Company grants share options to buy common shares of the Company to directors, officers, employees and consultants. An individual is classified as an employee when the individual is an employee for legal or tax purposes, or provides services similar to those performed by an employee.

For employees, the fair value of share options is measured on the date of grant, using the Black-Scholes option pricing model and is recognized over the vesting period using graded vesting. Consideration paid for the shares on the exercise of share options is credited to share capital and the related share-based compensation is reclassified from the share-based payment reserve to share capital. When vested options are forfeited or are not exercised at the expiry date the amount previously recognized in share-based payment reserve is transferred to accumulated losses (deficit).

In situations where equity instruments are issued to non-employees and some or all of the goods or services received by the entity as consideration cannot be specifically identified, they are measured at fair value of

Significant Accounting Policies (continued)

the share-based payment. Otherwise, share-based payments are measured at the fair value of goods and services rendered.

e)

Property, Plant and Equipment

Property, plant and equipment are recorded at cost less accumulated depreciation.  Depreciation is recorded on the straight-line method based on the following rates which approximate the useful life of the assets:

	Aquaculture system	10-20%
	Tools and equipment	20%
	Leasehold improvements	10-14%
	Laboratory	10-20%
	Computer and office equipment	20%
	Vehicles	20%

Maintenance and repairs are charged to operations as incurred.

f)

Cash and Cash Equivalents

Cash equivalents consist of demand deposits with financial institutions, money market accounts, and highly liquid investments which are readily convertible into cash with maturities of three months or less when purchased.  

g)

Income Taxes

Income tax expense comprises current and deferred tax. Income tax is recognized in profit or loss except to the extent that it relates to items recognized directly in equity. Current tax expense is the expected tax payable on taxable income for the year, using tax rates enacted or substantively enacted at period end, adjusted for amendments to tax payable with regards to previous years.

Deferred tax is recorded using the liability method, providing for temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. Temporary differences are not provided for relating to goodwill not deductible for tax purposes, the initial recognition of assets and liabilities that affect neither accounting nor taxable loss, and differences relating to investments in subsidiaries to the extent that they will be probably not reverse in the foreseeable future. The amount of deferred tax provided is based on the expected manner of realization or settlement of the carrying amount of assets and liabilities, using tax rates enacted or substantively enacted at the balance sheet date.

A deferred tax asset is recognized only to the extent that it is probable that future taxable profits will be available against which the asset can be utilized. To the extent that the Company does not consider it probable that a deferred tax asset will be recovered, it provides a valuation allowance against that excess.  

h)

Financial Instruments

Financial assets are classified into one of the following categories based on the purpose for which the asset was acquired. All transactions related to financial instruments are recorded on a trade date basis. The Company’s accounting policy for each category is as follows:

Stellar Biotechnologies, Inc

(Unaudited – Prepared by Management)

Significant Accounting Policies (continued)

Financial assets at fair value through profit or loss (“FVTPL”)

A financial asset is classified at fair value through profit or loss if it is classified as held for trading or is designated as such upon initial recognition. Financial assets are designated as at FVTPL if the Company manages such investments and makes purchase and sale decisions based on their fair value in accordance with the Company’s risk management strategy. Attributable transaction costs are recognized in profit or loss when incurred. FVTPL are measured at fair value, and changes are recognized in profit or loss.

Held-to-maturity (“HTM”)

These assets are non-derivative financial assets with fixed or determinable payments and fixed maturities that the Company’s management has the positive intention and ability to hold to maturity. These assets are measured at amortized costs using the effective interest method. If there is objective evidence that the asset is impaired, determined by reference to external credit ratings and other relevant indicators, the financial asset is measured at the present value of estimated future cash flows. Any changes to the carrying amount of the investment, including impairment losses, are recognized in profit or loss.

Loans and receivables

Loans and receivables are financial assets with fixed or determinable payments that are not quoted on an active market. Such assets are initially recognized at fair value plus any direct attributable transaction costs. Subsequent to initial recognition loans and receivables are measured at amortized cost using the effective interest method, less any impairment loss.

Available for sale (“AFS”)

Non-derivative financial assets not included in the above categories are classified as available-for-sale. They are carried at fair value with changes in fair value recognized directly in equity. Where a decline in the fair value of an available-for-sale financial asset constitutes objective evidence of impairment, the amount of the loss is removed from equity and recognized in profit or loss.

The Company has classified its financial assets as follows:

·

Cash and cash equivalents are classified as FVTPL.

·

Accounts receivable are classified as loans and receivables.

Financial liabilities

All financial liabilities are initially recorded at fair value.  Financial liabilities are classified into one of the following two categories:

Fair value through profit or loss (“FVTPL”)

This category comprises derivatives, or liabilities, acquired or incurred principally for the purpose of selling or repurchasing it in the near term. They are carried in the statement of financial position at fair value with changes in fair value recognized in profit or loss.

Warrants which do not meet the criteria to be classified as an equity instrument are classified as fair value through profit or loss financial liabilities.

Other financial liabilities

Financial liabilities classified as other financial liabilities are measured at amortized cost.

The Company has classified its financial liabilities as follows:

·

Accounts payable is classified as other financial liabilities.

·

Warrant liability is classified as FVTPL.

Impairment of financial assets

Financial assets, other than those at FVTPL, are assessed for indicators of impairment at the end of each reporting period. Financial assets are impaired when there is objective evidence that, as a result of one or more events that occurred after the initial recognition of the financial assets, the estimated future cash flows of the assets have been impacted.

For all financial assets objective evidence of impairment could include:

·

significant financial difficulty of the issuer or counterparty; or

·

default or delinquency in interest or principal payments; or

·

it becoming probable that the borrower will enter bankruptcy or financial re-organization.

i)

Impairment of Tangible and Intangible Assets

At the end of each reporting period, the Company’s assets are reviewed to determine whether there is any indication that those assets may be impaired. If such indication exists, the recoverable amount of the asset is estimated in order to determine the extent of the impairment, if any. The recoverable amount is the higher of fair value less costs to sell and value in use. Fair value is determined as the amount that would be obtained from the sale of the asset in an arm’s length transaction between knowledgeable and willing parties. In assessing value in use, the estimated future cash flows are discounted to their present value using pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset. If the recoverable amount of an asset is estimated to be less than its carrying amount, the carrying amount of the asset is reduced to its recoverable amount and the impairment loss is recognized in profit or loss for the period. For an asset that does not generate largely independent cash flows, the recoverable amount is determined for the cash generating unit to which the asset belongs.

Where an impairment loss subsequently reverses, the carrying amount of the asset (or cash-generating unit) is increased to the revised estimate of its recoverable amount, but to an amount that does not exceed the carrying amount that would have been determined had no impairment loss been recognized for the asset (or cash-generating unit) in prior years. A reversal of an impairment loss is recognized immediately in profit or loss.

j)

Biological Assets

Biological assets are keyhole limpets which are bearer assets to produce KLH.  They are measured at fair value less costs to sell.  Fair value is based on market prices of mature keyhole limpets which are harvested from the ocean.  The Company expenses the costs of aquaculture.  Fair value gains and losses are determined upon remeasurement at each reporting period.  Biological assets include production limpets and dedicated limpet colonies under contract.

k)

Research and Development

The Company is involved in research and development.  Research costs, including materials and salaries of employees directly involved in research efforts, are expensed as incurred. Development costs are expensed in the period incurred, unless they meet criteria for technical, market and financial feasibility, in which case they are deferred and amortized over the estimated life of related products.  Research and development expenses are shown as a separate line item on the consolidated statements of comprehensive loss.   As at February 29, 2012, the Company had no deferred development costs.

l)

Foreign Exchange

Items included in the financial statements of the Company’s subsidiary are measured using the currency of the primary economic environment in which the entity operates (the “functional currency”). The functional currency of the parent and its subsidiary is the US dollar.

Transactions in currencies other than the US dollar are recorded at exchange rates prevailing on the dates of the transactions. At the end of each reporting period, monetary assets and liabilities denominated in foreign currencies are translated at the period end exchange rate while non-monetary assets and liabilities are translated at historical rates. Revenues and expenses are translated at the exchange rates approximating those in effect on the date of the transactions. Exchange gains and losses arising on translation are included in comprehensive loss.

The Company recognizes commercial sales revenue when KLH product is delivered assuming there is persuasive evidence of an arrangement, the fee is fixed or determinable, and collectability is reasonably assured.  In limited circumstance, the Company retains ownership until the product is received and inspected by the customer; revenue is recognized upon satisfaction of these conditions.  The Company documents arrangements with customers with purchase orders and sales agreements.  

Commercial sales revenue includes sales made under supply agreements with customers for a fixed price per gram of KLH products based on quantities ordered, including those produced from the customer’s dedicated limpet colonies.  The supply agreements are on a non-exclusive basis except within that customer’s field of use.

n)

Grant Revenue Recognition

The Company has taken the income approach to recognizing grant revenue.  The Company recognizes grant revenue when there is reasonable assurance that the Company will comply with the conditions attached, the benefits have been earned and it is reasonably assured of collection.  An appropriate amount in respect to earned revenue will be recognized as revenue in the period that the Company is assured of fulfilling the grant requirements.  Grant advances received prior to revenue recognition are recorded as deferred revenue.

Contract Income Recognition

Contract income is recognized when reasonable assurance exists regarding measurement and collectability. An appropriate amount in respect to earned revenue will be recognized as revenue in the period that the Company is assured of fulfilling the contract requirements.

Contract income is earned on both the initial set up fee for establishment of limpet colonies dedicated to meet the needs of the customer and monthly fees to maintain those dedicated limpet colonies.   The Company also has the right to use raw material produced from dedicated limpet colonies at no cost with prior written consent.

Contract income is earned from research collaboration agreements whereby revenue is earned through sharing access to the Company’s KLH manufacturing methods and analytical data as well as when certain project milestones are met.  The customer and the Company will jointly own the rights to practice the resulting intellectual properties within specified fields of use.

p)

Accounting Standards Issued But Not Yet Applied

The Company has reviewed new and revised accounting pronouncements that have been issued but are not yet effective. The Company has not early adopted any of these standards and is currently evaluating the impact, if any, that these standards might have on its financial statements.

Accounting Standards Issued and Effective January 1, 2013

IFRS 9 Financial Instruments replaces the current standard IAS 39 Financial Instruments: Recognition and Measurement, replacing the current classification and measurement criteria for financial assets and liabilities with only two classification categories: amortized cost and fair value.

IFRS 10 Consolidated Financial Statements establishes principles for the presentation and preparation of consolidated financial statements when an entity controls one or more other entities. IFRS 10 supersedes IAS 39, Financial Instruments: Recognition and Measurement.

IFRS 11 Joint Arrangements establishes the core principle that a party to a joint arrangement determines the type of joint arrangement in which it is involved by assessing its rights and obligations and accounts for those rights and obligations in accordance with that type of joint arrangement.

IFRS 12 Disclosure of Involvement with Other Entities requires the disclosure of information that enables users of financial statements to evaluate the nature of, and risks associated with, its interests in other entities and the effects of those interests on its financial position, financial performance and cash flows.

Significant Accounting Policies (continued)

IFRS 13 Fair Value Measurement defines fair value, sets out in a single IFRS framework for measuring fair value and requires disclosures about fair value measurements. IFRS 13 applies when another IFRS requires or permits fair value measurements or disclosures about fair value measurements (and measurements, such as fair value less costs to sell, based on fair value or disclosures about those measurements), except for: share-based payment transactions within the scope of IFRS 2 Share-based Payment; leasing transactions within the scope of IAS 17 Leases; measurements that have some similarities to fair value but that are not fair value, such as net realizable value in IAS 2 Inventories or value in use in IAS 36 Impairment of Assets.

IAS 27 Separate Financial Statement (Amended) has the objective of setting standards to be applied in accounting for investments in subsidiaries, joint ventures, and associates when an entity elects, or is required by local regulations, to present separate (non-consolidated) financial statements.

IAS 28 Investments in Associates and Joint Ventures (Amended) prescribes the accounting for investments in associates and sets out the requirements for the application of the equity method when accounting for investments in associates and joint ventures. IAS 28 applies to all entities that are investors with joint control of, or significant influence over, an investee (associate or joint venture).

Financial Instruments

The Company is exposed to various financial instrument risks and assesses the impact and likelihood of this exposure. These risks include liquidity risk, credit risk, currency risk and interest rate risk. Where material, these risks are reviewed and monitored by the Board of Directors.

Capital Management

The Company manages its capital to safeguard the Company’s ability to continue as a going concern, so that it can continue to provide adequate returns to shareholders and benefits to other stakeholders, and to have sufficient funds on hand for business opportunities as they arise.

The Company considers the items included in share capital as capital. The Company manages the capital structure and makes adjustments to it in the light of changes in economic conditions and the risk characteristics of the underlying assets. In order to maintain or adjust the capital structure, the Company may issue new shares through short-term prospectuses, private placements, sell assets, incur debt, or return capital to shareholders. As at February 29, 2012, the Company does not have any debt and is not subject to externally imposed capital requirements.

Financial Instruments (continued)

Interest Rate Risk

Interest rate risk is the risk that the fair value of future cash flows from a financial instrument will fluctuate as a result in market interest rates.  The Company is exposed to interest rate risk to the extent that the cash maintained at the financial institutions included in the Company’s cash and cash equivalents are subject to a floating rate of interest.

The interest rate risks on cash are not considered significant.

Foreign Exchange Risk

The Company incurs operating expenses and capital expenditures mostly in US dollars, with some operating expenses incurred in Canadian dollars which are subject to foreign currency fluctuations. The fluctuation of the US dollar in relation to Canadian dollars will have an impact upon the profitability of the Company and may also affect the value of the Company’s assets and the amount of shareholders’ equity.  The Company has not entered into any agreements or purchased any instruments to hedge possible currency risks.  At February 29, 2012, the US dollar was equal to 0.99656 Canadian  dollars.  The currency risk is considered to be insignificant.

Credit Risk

Credit risk is the risk of an unexpected loss if a customer or third party to a financial instrument fails to meet its contractual obligations.  Financial instruments that potentially subject the Company to a concentration of credit risk consist primarily of cash, cash equivalents and accounts receivable.  Management’s assessment of the Company’s credit risk for cash and cash equivalents is low as cash and cash equivalents are held in financial institutions believed to be credit worthy.  The Company limits its exposure to credit loss by placing its cash with major financial institutions and invests only in short-term obligations.

Approximately 99% of the Company’s commercial sales and contract income during the period ended February 29, 2012 were from two customers (2011 - 86% from one customer,). All of the grant revenue during the period ended February 29, 2012 was received from NSF (2011 – 81% from IRS grants and 19% from NSF).

Approximately 81% of the Company’s accounts receivables at February 29, 2012, were from one customer (August 31, 2011 - 25% from two customers, September 1, 2010 - 84% from two customers), and $Nil were from the NSF grants (August 31, 2011 - 75%, September 1, 2010 - 16%).

While the Company is exposed to credit losses due to the non-performance of its counterparties, the Company considers the risk of this remote.  The Company estimates its maximum credit risk for accounts receivable at the amount recorded on the balance sheet.  

Liquidity Risk

Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they fall due.  The Company attempts to manage liquidity risk by maintaining sufficient cash and cash equivalent balances. Liquidity requirements are managed based on expected cash flows to ensure that there is sufficient capital in order to meet short term obligations.  As at February 29, 2012, the Company had a cash and cash equivalents balance of $2,945,496 (August 31, 2011 - $4,145,492, September 1, 2010 - $2,003,296) to settle current liabilities of $310,534 (August 31, 2011 - $159,137, September 1, 2010 - $420,610).

Financial Instruments (continued)

Fair Value

The fair value of the Company’s financial instruments is believed to equal the carrying amounts due to the short terms to maturity.

Fair value measurement disclosures include classification of financial instrument fair values in a fair value hierarchy comprising three levels reflecting the significance of the inputs used in making the measurements, described as follows:

Level 1:

Valuations based on quoted prices (unadjusted) in active markets for identical assets or liabilities;

Level 2:

Valuations based on directly or  indirectly observable inputs in active markets for similar assets or liabilities, other than Level 1  prices such  as quoted interest or  currency exchange rates;  and

Level 3:

Valuations based on significant inputs that are not derived from observable market data, such as discounted cash flow methodologies based on internal cash flow forecasts.

The Company’s fair value of cash and cash equivalents under the fair value hierarchy is measured using Level 1 inputs and fair value of the warrant liability is measured using Level 2 inputs.

Warrant Liability – Warrants Issued With Canadian Dollar Exercise Prices

Equity offerings were completed in previous periods whereby warrants were issued with exercise prices denominated in Canadian dollars.   The Company’s functional currency is in US dollars.  As a result of having exercise prices denominated in other than the Company’s functional currency, these warrants meet the definition of derivatives and are therefore classified as derivative liabilities measured at fair value with adjustments to fair value recognized through the Statements of Consolidated Loss.  The fair value of the warrants was determined using the Black-Scholes option pricing model at the end of each reporting period.  Upon exercise of the warrants, the fair value of warrants included in derivative liabilities was reclassified to equity.

The fair value of warrants exercised during the periods ended February 29, 2012 and 2011 was determined using the Black-Scholes option pricing model, using the following assumptions:

		2012	2011
	Risk free interest rate	2.49%	3.15%
	Expected life (years)	0.11	0.78
	Expected share price volatility	110%	104.79%

The fair value of warrants granted was determined using the Black-Scholes option pricing model, using the following weighted average assumptions at the end of each reporting period:

		2012	2011
	Risk free interest rate	N/A	1.61%
	Expected life (years)	N/A	1.1
	Expected share price volatility	N/A	107%
	Expected dividend yield	N/A	0%

Option pricing models require the input of highly subjective assumptions regarding volatility.  The Company has used historical volatility to estimate the volatility of the share price.  

Options

The Company has a stock option plan (“the Plan”) to be administered by the Board of Directors, which has the discretion to grant options for up to a maximum of 20% of the issued and outstanding share capital amount and subject to a maximum of 8,785,000 shares.  The exercise price of an option  is subject to a minimum of $0.10

Option pricing models require the input of highly subjective assumptions including the expected price volatility.  Changes in the subjective input assumptions can materially affect the fair value estimate, and therefore the existing models do not necessarily provide a reliable single measure of the fair value of the Company’s stock options.  The estimated fair value of the stock options granted during the periods ended February 29, 2012 and 2011 was determined using a Black-Scholes option pricing model with the following weighted average assumptions:

		2012	2011
	Risk free interest rate	1.51%	2.69%
	Expected life (years)	7.0	7.0
	Expected share price volatility	141%	110%
	Expected dividend yield	0%	0%

The average fair value of stock options awarded during the period was $0.41 and $0.87 respectively.

First Time Adoption of IFRS (continued)

In preparing the opening IFRS statement of financial position and the financial statements for the interim period ended February 28, 2011 and annual period ended August 31, 2011, the Company has adjusted amounts reported previously in financial statements prepared in accordance with Canadian GAAP.  An explanation of how the transition from Canadian GAAP to IFRS has effected the Company’s financial position and financial performance is set out in the following tables.

The guidance for first time adoption of IFRS is set out in IFRS 1.  IFRS 1 provides for certain mandatory exceptions and optional exemptions for first time adopters of IFRS.  The Company has elected to take the following IFRS 1 optional exemptions:

(a)

Optional exemptions

Share-based payments

IFRS 2, Share-based Payments, encourages application of its provisions to equity instruments granted on or before November 7, 2002, but permits the application only to equity instruments granted after November 7, 2002 that were not vested by the Transition Date.  The Company elected to take the exemption available under IFRS 1 and applied IFRS 2 for all equity instruments granted after November 7, 2002 that had not vested by the Transition Date.

Financial Instruments: Presentation

IAS 32, Financial Instruments: Presentation requires an entity to split a compound financial instrument at inception into separate liability and equity components.  If the liability component is no longer outstanding, retrospective application of IAS 32 involves separating two portions of equity.  The first portion is in retained earnings and represents the cumulative interest accreted on the liability component.  The other portion represents the original equity component.  However, in accordance with this IFRS, a first-time adopter need not separate these two portions if the liability component is no longer outstanding at the date of transition to IFRS.

(b)

Mandatory exceptions

Estimates

In accordance with IFRS 1, an entity’s estimates under IFRS at the date of IFRS transition must be consistent with estimates made for the same date under previous Canadian GAAP, unless there is objective evidence that those estimates were in error.  The Company’s IFRS estimates as of September 1, 2010 are consistent with Canadian GAAP estimates for the same date.

Reconciliation of Canadian GAAP and comprehensive loss to IFRS

IFRS requires an entity to reconcile equity, comprehensive loss and cash flows for prior periods.  The changes made to the statement of financial position and statements of comprehensive loss as shown below have resulted in reclassifications of various amounts on the statements of cash flows, however as there have been no material adjustments to the net cash flows, no reconciliation of the statement of cash flows has been prepared.

15.

First Time Adoption of IFRS (continued)

Explanations for the adjustments are as follows:

(i)

Share-based payments

IFRS 2 is effective for the Company as at September 1, 2010 and is applicable to:

·

New grants for share-based payments subsequent to September 1, 2010

·

Equity-settle share-based compensation awards granted subsequent to November 7, 2002 and that vest after September 1, 2010; and

·

Awards that are modified on or after September 1, 2010, even if the original grant of the award was not accounted for in accordance with IFRS 2.

Canadian GAAP allows the Company to calculate the fair value of the share-based compensation on all awards granted and recognizes the expense from the date of grant over the vesting period using the straight-line methodology.  The Company determines the fair value of share options granted using the Black-Scholes option pricing model.

IFRS 2 requires each tranche in an award with graded vesting features to be treated as a separate grant with a different vesting date and fair value.  Each grant is accounted for on that basis.

As a result, share-based payment reserves was increased by $29,216 at September 1, 2010 (February 28, 2011 - $88,978; August 31, 2011 - $44,809) and deficit has been increased by $29,216 at September 1, 2010 (February 28, 2011 - $88,978; August 31, 2011 - $44,809).  The impact on loss and comprehensive loss for the period ended February 28, 2011 was an increase of share-based payments of $59,762 (year ended August 31, 2011 - $15,593).

(ii)

Biological assets

IFRS 41 is effective for the Company as at September 1, 2010.  Biological assets are living plants or animals including those which can provide agricultural produce.  The Company’s keyhole limpet colonies are bearer assets from which KLH is harvested.  

Under IFRS, the biological assets are recorded at fair value less costs to sell, measured upon initial recognition and at the end of each reporting period. Accordingly, biological assets increased by $3,173 at September 1, 2010 (February 28, 2011 - $6,265; August 31, 2011 - $5,763).  The impact on loss and comprehensive loss for the period ended February 28, 2011 was $3,092 (year ended August 31, 2011 - $2,590).  

(iii)

Warrant Liability

Under IFRS, the warrants issued by the Company with an exercise price denominated in a currency other than its functional currency must be classified as liabilities (as they do not meet the definition if an equity instrument) and are recognized at fair value with changes in fair value being recognized as a profit or loss. There is no such requirement under Canadian GAAP as warrants issued by the Company meet the definition of an equity instrument. The Company’s outstanding warrants are denominated in Canadian dollars and the functional currency is the US dollar therefore the Company will recognize the warrants as a liability with changes to the fair value of the liability being recognized in the Statements of Consolidated Loss.

(iii)

Warrant Liability (continued)

As a result, warrant liability increased by $797,310 at September 1, 2010 (February 28, 2011 - $7,349,405; August 31, 2011 - $1,527,374).  The impact on loss and comprehensive loss for the period ended February 28, 2011 was a gain of $4,485,746 (year ended August 31, 2011 - $1,220,437).

16.

Loss Recovery

A shipment of KLH was damaged by a vendor.  The vendor agreed to reimburse the Company for the value of the KLH.  In accordance with IAS 37, Provisions, Contingent Liabilities and Contingent Assets, the loss recovery was recorded during the period ended February 29, 2012 when the realization of income was virtually certain.

Description of Corporate Entity

Stellar Biotechnologies, Inc. (“the Company” or “Stellar”, formerly CAG Capital Inc.) is listed on the TSX Venture Exchange (“the Exchange”) as a Tier 2 issuer under the trading symbol KLH since April 19, 2010 (formerly under CAG.P). The Company’s head office is located in Port Hueneme, California, USA.

Stellar is a company with biotech and pharmaceutical customers and research partners, $6 million in research having been conducted with US government National Institutes of Health (“NIH”) and National Science Foundation (“NSF”) grants, with a portfolio of intellectual property involving new aquaculture and marine culture processes as well as technology for producing pharmaceutical formulations of Keyhole Limpet Hemocyanin (“KLH”) that sell for $5,000 - $200,000 per gram into the medical, academic and research markets. KLH is an essential component for many cancer vaccines and highly anticipated therapeutic vaccines, including those for lymphoma, sarcoma, small cell lung cancer, Alzheimer’s disease, rheumatoid arthritis, lupus, and Post Traumatic Stress Disorder chemical dependencies.

Global Overview of KLH

The Company’s core activity is production of purified KLH for use in a new class of medicines known as therapeutic vaccines and in immunological research. The Company is the only company dedicated solely to developing and commercializing KLH. Demand for its KLH is driven by over a dozen biopharmaceutical companies that have advanced KLH-based therapeutic vaccines in clinical trials for a wide variety of serious chronic diseases.

KLH is a potently immunogenic (i.e. a substance that induces an immune response) high-molecular-weight protein. It offers an ideal carrier molecule for vaccine antigens (i.e., substances that promote the generation of antibodies) against cancers and infectious agents. The combination of an antigen against specific tumor cell-types, conjugated to the Immunogenic (“IMG”) KLH molecule, is the basis for a proven strategy for a new class of drugs known as therapeutic vaccines. Potent yet proven safe in humans, KLH is highly prized as a critical component of several important therapeutic vaccines including vaccines for lymphoma, bladder, breast, colon, and other cancers.

The Company is positioned to become the premier worldwide supplier of vaccine-grade KLH. The commercial prospects of KLH vaccines under development are threatened by one common factor; reliance on KLH from a fragile wild population of M. crenulata, which is found only sporadically in the coastal waters from central California to northern Baja California, Mexico. There is currently no regulated fishery to protect this limited population from over-exploitation and fishery stocks are being rapidly depleted before a bona fide regulated commercial fishery can be instituted to mitigate the unsustainable harvesting pressure. With the expected imminent potential approval of KLH-based vaccines, the limited natural population of M. crenulata will not sustain KLH supplies. We believe that the Company is the only company that has aquaculture and harvesting technology to ensure sustainable supplies.

The Company has developed what is believed to be the world’s only dedicated aquaculture technology and captive, hatchery-reared populations of M. crenulata for sustainable vaccine-grade KLH production. The Company’s intellectual properties include sophisticated proprietary aquaculture methods, the only patented non-lethal hemolymph extraction process, and proprietary vaccine-grade protein purification methods for production of KLH that meets the specific needs of vaccine developers.

Currently, the Company provides cGMP (current good manufacturing practices) KLH products to the biopharmaceutical and vaccine development markets, with KLH supply contracts in place with two vaccine developers, including one of the world’s largest pharmaceutical companies, and it expects to complete contract negotiations with additional customers in the future.

Company’s Technology

The Company’s proprietary intellectual property includes patent, patent pending and key trade secrets related to sourcing and purifying KLH for medical markets by spawning and maintaining the rare keyhole limpet which is found only in the slender strip of ocean off the coast of northern Baja to central California; non-lethal hemolymph extraction technology for environmentally sustainable production of KLH and highly efficient manufacturing methods for the purification of various formulations of the KLH molecule for use in dynamic pharmaceutical and veterinary markets as a powerful immune stimulant and vaccine carrier protein with a long history of efficacy, safety and low toxicity.

Corporate Goals and Objectives

The Company’s goal is to execute its business strategy:

1.

Produce, maintain and develop keyhole limpets through key intellectual property (“IP”).

2.

Continuously advance key IP to extract, purify and formulate KLH profitably, while increasing the number and maintaining the good health of the essential source animals.

3.

Market and sell the Company’s formulations of KLH and use consistent efforts to expand markets, promote the use of KLH within the academic, research, pharmaceutical, biotech and medical diagnostic markets.

4.

Alone and in partnership with others, develop and sell as many proprietary KLH-based products as possible for the medical diagnostic and therapeutic markets.

Since our report in November 2011, Stellar has continued to make significant progress on many important fronts and continues to advance our corporate mandate and achieve goals for long-term shareholder benefit.

Grants and Non-Dilutive Funding

We remain active in the pursuit of opportunities through grant programs that offer non-dilutive funding for research and business development for projects that align directly with the Company’s strategic pathway. In December 2010, the Company announced a $99K award from the National Science Foundation through the prestigious Technology Enhancement for Commercial Partnerships (“TECP”) program. This grant was further expanded in August 2011 through a $499K Phase IIB supplement award from NSF to continue funding for Stellar’s SBIR research for two additional years. These awards increased the total NSF SBIR grant funding for Aquaculture technology development to a total of more than $1,000,000.

Corporate Milestones

The Company continues to make progress on the final two of three milestones disclosed in our Qualifying Transaction documents in 2010. We expect to announce positive results on achieving both goals in 2012. Stellar has also moved quickly to develop its suite of diagnostic products and in April 2012 we announced the launch of the first suite of 6 preclinical ELISA (enzyme-linked immunosorbent assays) test kits targeted for the immunotoxicity drug development markets.

Business Development

In December 2010, we announced the exclusive in-licensing of Bayer intellectual property we developed jointly with Bayer Innovation GmbH (“BIG” or “Bayer”) as an outgrowth of our previous joint development agreement. In May 2011 we met with Bayer and another company in Germany to explore opportunities to broaden the relationship to include possible future products. During the second quarter of fiscal year 2012, we completed a successful cGMP manufactured lot of KLH20-MV using the method jointly developed under the collaborative agreement. The Company is planning to amend its DMF to reflect the optimized manufacturing method.

In May 2011 Stellar entered into an agreement for marketing and sales with SAFC®, a business unit of Sigma-Aldrich (NASDAQ: SIAL) a global leader in biopharmaceutical contract manufacturing. Under the agreement, Stellar will produce KLH commercial intermediate and SAFC will sell, distribute and market cGMP-grade HMW KLH (high molecular weight keyhole limpet hemocyanin) that uses only Stellar aquaculture-derived KLH for applications in therapeutic vaccines

This collaboration is expected to increase access to a scalable source for KLH, a critical immunostimulatory vaccine carrier protein that will enable the transition from clinical research to commercialization of conjugate vaccine platforms, while managing costs and the risk of supply constraints faced by suppliers that rely on the exploitation of the critically limited natural resource. In September 2011, we announced that the Company received the first purchase order for KLH under this agreement, for a low six figure US$ amount.

With guidance received during its first Pre-Investigational Device Exemption (“Pre-IDE”) meeting with the U.S. Food and Drug Administration (“FDA”) in May 2011, Stellar is continuing the pre-clinical testing of its KLH products to develop the essential safety and efficacy data needed to execute the Company’s regulatory strategy for approval of its diagnostic product for human use. If approved in the future, this product platform has the potential to dramatically increase the use of Stellar KLH.

During October 2011, Stellar entered into an exclusive manufacturing and supply agreement with Life Diagnostics (www.lifediagnostics.com). Life Diagnostics is a leader in the manufacture and sale of ELISA kits, purified biomarkers and antibodies for cardiovascular, inflammation, immunotoxicity and immunology research. Under the agreement, Life Diagnostics will utilize Stellar’s high-quality KLH to develop and manufacture Stellar brand KLH ELISA test kits for the detection of anti-KLH antibodies, for use in the growing immunotoxicity and immunology research markets.

This collaboration is expected to meet the increasing need among pharmaceutical researchers for improved test sensitivity, product consistency and analytical performance. Stellar will supply all aquaculture-derived KLH required for production of the ELISA test kits. Life Diagnostics will manufacture the ELISA test kits, and will work closely with Stellar in the commercial marketing and sale of these products. Initially, the agreement covers six different Stellar KLH ELISA products. The launch of Stellar KLHTM ELISA Test Kits occurred in April 2012.

In April 2012 The Company announced that it had entered into an agreement with the University of Guelph (Ontario, Canada) under which the University has granted Stellar an exclusive option to license a patent pending technology for the development of a vaccine candidate against Clostridium difficile infection (“CDI”). Clostridium difficile is a major and growing cause of mortality and morbidity in hospitalized patients. CDI-related treatments in the U.S. and European countries are estimated at more than $7 billion a year. This agreement accentuates Stellar’s commitment to a strategy of acquiring promising vaccine candidates as well as other infectious disease targets that may work synergistically with Stellar’s KLH platform, and have potential to address serious, unmet global clinical needs.

Team and Physical Plant Additions/Changes

To meet corporate objectives, Stellar has grown dramatically. From 6 employees in April 2010, to a dozen by the end of 2010; we are now a dedicated team of 18 and occupy an additional 4,000 sq. ft. of corporate space 600 yards from the gate to our aquaculture and lab facilities on our government-secured harbour facility, as well as additional lab and clean-room manufacturing space.

U.S. Stock Listing and Shareholders Rights Plan

The Company filed a draft Form 20-F registration statement application with the SEC during February 2012 as the first step toward registration of its shares in the United States. Once the Form 20-F becomes effective with the SEC, the Company will become a fully reporting issuer in the United States. It will also allow the Company to consider the advantages of listing on one of the US exchanges.

During February 2012, the Company was listed on the Frankfurt Stock Exchange (FSE) as a way to broaden our shareholder base and awareness in Germany and Europe.

The Company adopted a Shareholder Rights Plan effective December 13, 2011, which was ratified and approved by shareholders at its Annual General Meeting held in January 2012.

Aquaculture

In 2011 the Company completed expansion of its hatchery facility for production on keyhole limpet larvae at its Port Hueneme facility, and has implemented production of limpets at a scale suitable to support multiple culture sites. The Company completed negotiation of a term sheet with a regional aquaculture producer for additional culture capacity to accommodate the increase in hatchery production and to geographically diversify some of the keyhole limpet population. The Company is now conducting the studies required by the California Department of Fish and Game (“CDFG”) to certify the Port Hueneme hatchery facility for transport and stocking of limpets throughout the state of California. It is expected that this will expand our competitive advantage in this field, with newly implemented technologically developed under our NSF grant for the production of limpets in numbers far beyond what we believe could be available from any other source. We remain confident that we have the only renewable, sustainable, aquaculture-based supply source for the important immunogenic protein carrier, cGMP-grade KLH, and are unaware of any other company with the licenses permits, facilities or intellectual property to compete with us in this arena.

Corporate Development

We have made changes in the board of directors and at the CFO position that were anticipated as a part of the transition from a private company to a public company. The important, one-year transitional positions for which the director and CFO signed on originally were filled by strategically selected team members. Our website has also changed significantly to reflect our evolving market focus. We encourage you to visit our site and sign up to be on our list to receive regular updates by visiting http://www.stellarbiotechnologies.com/contact/request_info/.

The Stellar team looks forward to the future with great enthusiasm and the expectation that we will continue to achieve the corporate goals and business objectives that bring value to the Company and to serve the interests of our shareholders, partners, customers and employees.

Rent expense on these lease agreements for the six months ended February 29, 2012 was $85,231 (2011 - $49,200).

The Company has purchase order commitments totalling approximately $89,000 at February 29, 2012, for contract manufacturing organizations and consultants (August 31, 2011 - $184,000; September 1, 2010 - $117,000).

The Company has commitments under certain supply agreements with customers for fixed prices per gram on a non­exclusive basis except within that customer’s field of use.

Investor Relations

In addition to internal investor relations and corporate development personnel, the Company contracted the services of an investor relations firm, Maximus Strategic Consulting Inc., through September 2011 in order to increase exposure to North American and European retail brokers, institutions and investors. Beginning in January 2012, the Company contracted the services of TheBiotechPanel, Inc., a comprehensive investor relations provider specializing in financial and investor relations and communications focused on Europe. The term of the agreement is for six months, however it was discontinued in March 2012.

Financial Instruments and Risks

The Company is exposed to various financial instrument risks and assesses the impact and likelihood of this exposure. These risks include liquidity risk, credit risk, currency risk and interest rate risk. Where material, these risks are reviewed and monitored by the Board of Directors.

Capital Management

The Company manages its capital to safeguard the Company’s ability to continue as a going concern, so that it can continue to provide adequate returns to shareholders and benefits to other stakeholders, and to have sufficient funds on hand for business opportunities as they arise.

The Company considers the items included in share capital as capital. The Company manages the capital structure and makes adjustments to it in the light of changes in economic conditions and the risk characteristics of the underlying assets. In order to maintain or adjust the capital structure, the Company may issue new shares through short-term prospectuses, private placements, sell assets, incur debt, or return capital to shareholders. As at February 29, 2012, the Company does not have any debt and is not subject to externally imposed capital requirements.

Interest Rate Risk

Interest rate risk is the risk that the fair value of future cash flows from a financial instrument will fluctuate as a result in market interest rates. The Company is exposed to interest rate risk to the extent that the cash maintained at the financial institutions included in the Company’s cash and cash equivalents are subject to a floating rate of interest. The interest rate risks on cash are not considered significant.

Foreign Exchange Risk

The Company incurs operating expenses and capital expenditures mostly in US dollars, with some operating expenses incurred in Canadian dollars which are subject to foreign currency fluctuations. The fluctuation of the US dollar in relation to Canadian dollars will have an impact upon the profitability of the Company and may also affect the value of the Company’s assets and the amount of shareholders’ equity. The Company has not entered into any agreements or purchased any instruments to hedge possible currency risks. At February 29, 2012, the US dollar was equal to 0.99656 Canadian dollars. The currency risk is considered to be insignificant.

Credit Risk

Credit risk is the risk of an unexpected loss if a customer or third party to a financial instrument fails to meet its contractual obligations. Financial instruments that potentially subject the Company to a concentration of credit risk consist primarily of cash, cash equivalents and accounts receivable. Management’s assessment of the Company’s credit risk for cash and cash equivalents is low as cash and cash equivalents are held in financial institutions believed to be credit worthy. The Company limits its exposure to credit loss by placing its cash with major financial institutions and invests only in short-term obligations.

Approximately 99% of the Company’s commercial sales and contract income during the six months ended February 29, 2012 were from two customers (2011 - 86% from one customer,). All of the grant revenue during the six months ended February 29, 2012 was received from NSF (2011 - 81 % from IRS grants and 19% from NSF).

Approximately 81 % of the Company’s accounts receivables at February 29, 2012, were from one customer (August 31, 2011 - 25% from two customers; September 1, 2010 - 84% from two customers), and $Nil were from the NSF grants (August 31, 2011 - 75%; September 1, 2010 - 16%).

While the Company is exposed to credit losses due to the non-performance of its counterparties, the Company considers the risk of this remote. The Company estimates its maximum credit risk for accounts receivable at the amount recorded on the balance sheet.

Liquidity Risk

Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they fall due. The Company attempts to manage liquidity risk by maintaining sufficient cash and cash equivalent balances. Liquidity requirements are managed based on expected cash flows to ensure that there is sufficient capital in order to meet short term obligations. As at February 29, 2012, the Company had a cash and cash equivalents balance of $2,945,496 (August 31, 2011 - $4,145,492; September 1, 2010 - $2,003,296) to settle current liabilities of $310,534 (August 31, 2011 - $159,137; September 1, 2010 - $420,610).

Fair Value

The fair value of the Company’s financial instruments is believed to equal the carrying amounts due to the short terms to maturity.

Fair value measurement disclosures include classification of financial instrument fair values in a fair value hierarchy comprising three levels reflecting the significance of the inputs used in making the measurements, described as follows:

Level 1:

Valuations based on quoted prices (unadjusted) in active markets for identical assets or liabilities;

Level 2:

Valuations based on directly or indirectly observable inputs in active markets for similar assets or liabilities, other than Level 1 prices such as quoted interest or currency exchange rates; and

Level 3:

Valuations based on significant inputs that are not derived from observable market data, such as discounted cash flow methodologies based on internal cash flow forecasts.

The Company’s fair value of cash and cash equivalents under the fair value hierarchy is measured using Level 1 inputs and fair value of the warrant liability is measured using Level 2 inputs.

Risks and Uncertainties

Before making an investment decision with respect to the Company’s common shares, investors should carefully consider the following risk factors, in addition to the other information included or incorporated by reference into the annual report for the fiscal years ended August 31, 2011, 2010 and 2009.

The primary risks that may affect the Company during this fiscal year are summarized below. If any of the following risks occur, the Company’s business, results of operations or financial condition could be materially adversely affected:

·

The Company expects to continue to experience losses as a result of its ongoing research. It is difficult to estimate the timing and future costs of its research and development programs and the timing of the achievement of milestone revenues.

·

The Company may be unable to achieve certain milestones associated with the external partnerships, which could curtail future development and negatively impact the Company’s share price.

·

The Company does not currently have backup manufacturing capacity for some of its key products.

·

The loss of a key supplier of certain raw materials could have a material adverse effect on the Company’s business and financial condition.

·

The Company may not achieve its projected development goals in the timeframes it announces and expects.

·

Rapid technological change could make the Company’s products obsolete.

·

The Company faces uncertainties related to regulatory approval which could result in delays in product commercialization in certain territories.

·

Even if the Company obtains marketing approval, its products will be subject to ongoing regulatory review.

·

The Company’s products, if approved, may fail to achieve market acceptance.

·

Development of drugs can be costly and require years of research and development activities.

·

If the Company cannot raise additional capital on acceptable terms, it may delay or be unable to pursue further development of its product portfolio, obtain regulatory approvals or commercialize its product candidates.

·

If the Company is unable to protect its intellectual property rights, its competitors may develop and market products with similar features that may reduce demand for its products and the effective commercialization of its products may be inhibited.

·

The Company may become involved in lawsuits with respect to collaborations or protection or enforcement of its patents that would be expensive and time consuming.

·

If third-party manufacturers of the Company’s products fail to devote sufficient time and resources to its concerns, or if their performance is substandard, clinical trials and product introductions may be delayed and its costs may rise.

·

The Company may not be able to manufacture its products in commercial quantities, which would prevent it from marketing its products.

·

The Company may not be able to successfully achieve its goals.

·

The Company has international partners that expose it to additional business risks.

·

The Company may incur losses associated with foreign currency fluctuations.

·

The Company is subject to the risk of product liability claims, for which it may not have, or be able to obtain, adequate insurance coverage.

·

Future sales of common shares by the Company or its existing lenders or shareholders may cause its share price to fall.

·

The Company has never paid dividends on its common shares, and it does not anticipate paying cash dividends in the foreseeable future.

Transition to International Financial Reporting Standards (“IFRS”)

Please refer to the February 29, 2012 unaudited condensed interim consolidated financial statements on www.SEDAR.com for details on the Company’s transition to IFRS.

Note 15 – First Time Adoption of IFRS

Management’s Responsibility for Financial Statements

The information provided in this report, including the financial statements, is the responsibility of management. In the preparation of these statements, estimates are sometimes necessary to make a determination of future values for certain assets or liabilities. Management believes such estimates have been based on careful judgments and have been properly reflected in the accompanying financial statements.

Internal Controls Over Financial Reporting

Management has designed internal controls over financial reporting to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with IFRS. Lack of optimal segregation of duties has been observed due to the relatively small size of the Company, but management believes that these weaknesses have been adequately mitigated through management and director oversight.

Approval

The Board of Directors oversees management’s responsibility for financial reporting and internal control systems through an Audit Committee. This Committee meets periodically with management and annually with the independent auditors to review the scope and results of the annual audit and to review the financial statements and related financial reporting and internal control matters before the financial statements are approved by the Board of Directors and submitted to the shareholders of the Company. The Board of Directors of Stellar has approved the condensed interim consolidated financial statements and the disclosure contained in this MD&A. A copy of this MD&A will be provided to anyone who requests it.
