Recently Issued Accounting Pronouncements

In June 2011, the Financial Accounting Standard Board (“FASB”) issued Accounting Standard Update (“ASU”) 2011-05, Presentation of Comprehensive Income, which requires 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. ASU 2011-05 eliminates the option to present components of other comprehensive income as part of the statement of equity. ASU 2011-05 was effective for the Company for the three months ended March 31, 2012. The adoption of this guidance, which involves presentation and disclosures only, did not impact the Company’s financial statements.

No other new accounting pronouncements issued or effective during 2012 have had or are expected to have an impact on the Company’s financial statements.

Revenue Recognition

The Company recognizes revenues from the sales of product when title and risk of loss pass to the customer, which is generally when the product is shipped. Grant revenues are recognized as the reimbursable expenses are incurred over the life of the related grant. Grant revenues are deferred when reimbursable expenses have not been incurred.

The Company records allowances for discounts and product returns at the time of sales as a reduction of revenues as such allowances can be reliably estimated based on historical experience or known trends. Product returns are limited to specific mass retail customers for expiration of shelf life or unsold product over a period of time. The Company maintains a return policy that allows customers to return product within a specified period of time prior to and subsequent to the expiration date of the product. The estimate of the provision for returns is analyzed quarterly and is based upon many factors, including industry data of product return rates, historical experience of actual returns, analysis of the level of inventory in the distribution channel, if any, and reorder rates. If the history or product returns changes, the reserve will be adjusted. While the Company believes that the reserves it has established are reasonable and appropriate based upon current facts and circumstances, applying different judgments to the same facts and circumstances would result in the estimated amounts for sales returns and chargebacks to vary. Because the ProBiora3 products have only recently been introduced, the Company could experience different circumstances in the future and these differences could be material.

The Company has granted guaranteed rights of return at various times to certain customers. At this time there is only one active mass retail customer account and two dental distributors with guaranteed rights of return. Orders are processed and shipped on these accounts however the Company defers recognition of revenue until the customer provides notification to the Company that the product has sold to the end consumer. Once notification has been received and verified, the Company will record revenue in that accounting period.

Use of Estimates

The preparation of financial statements in conformity with GAAP 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, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The principal areas of estimation reflected in the financial statements are stock based compensation, valuation of warrants, inventory obsolescence reserve, sales returns and allowances and the allowance for doubtful accounts.

Fair Value of Financial Instruments

The fair value of the Company’s cash and cash equivalents, accounts payable and accrued expenses approximate their carrying values due to their short-term nature.

Guaranteed Rights of Return

The Company has granted guaranteed rights of return to one mass retailer and two dental distributors’ customer accounts. The Company defers recognition of revenue on these accounts until the customer provides notification to the Company that the product has been sold to the end consumer. Once notification has been received and verified, the Company records revenue in that accounting period. The Company had approximately $22,000 and $26,000 of revenue deferred under guaranteed rights of return arrangements included in deferred revenue in the balance sheets as of March 31, 2012 and December 31, 2011, respectively.

Inventory

Inventory is stated at the lower of cost or market. Cost, which includes material, labor and overhead, is determined on a first-in, first-out basis. On a quarterly basis, we analyze our inventory levels and reserve for inventory that is expected to expire prior to being sold, inventory that has a cost basis in excess of its expected net realizable value, inventory in excess of expected sales requirements, or inventory that fails to meet commercial sale specifications. Expired inventory is disposed of and the related costs are written off to the reserve for inventory obsolescence. The inventory reserve was approximately $65,000 and $65,000 as of March 31, 2012 and December 31, 2011, respectively.

Consigned Inventory

The Company has authorized a consignment inventory arrangement with one of its mass retail customers. As of March 31, 2012 and December 31, 2011, the Company has approximately $29,000 and $29,000, respectively, of inventory on consignment located at the retailers’ stores and warehouses, which is included in our inventory reserve. Once consignment inventory has been sold by this customer, the customer notifies the Company of the sale and the Company records revenue in that accounting period. The Company authorizes the replenishment of consignment inventory based on orders placed by the customer. The Company is provided with weekly reports of consignment sales activity and balances.

Net Loss Per Share

During all periods presented, the Company had securities outstanding that could potentially dilute basic earnings per share in the future, but were excluded from the computation of diluted net loss per share, as their effect would have been antidilutive. Because the Company reported a net loss for all periods presented, shares associated with the convertible revolving note payable, stock options and warrants are not included because they are antidilutive. Basic and diluted net loss per share amounts are the same for the periods presented. Net loss per share is computed using the weighted average number of shares of common stock outstanding.

Concentrations

The Company is dependent on key suppliers to provide probiotics, blending, warehousing and packaging of its EvoraPlus, EvoraPlus Kids, EvoraPro, and Teddy’s Pride products. The Company had four key suppliers during the three months ended March 31, 2012 and 2011, respectively. The majority of the Company’s cost of sales are from these key suppliers during the three months ended March 31, 2012 and 2011. Accounts payable and accrued expenses for these vendors totaled approximately $2,000 and $108,000 as of March 31, 2012 and December 31, 2011, respectively.
