2.  Summary of Significant Accounting Policies

Basis of Presentation

Our consolidated financial statements include our accounts and the accounts for our wholly owned subsidiary, Rockwell Transportation, Inc.  All intercompany balances and transactions have been eliminated in consolidation. The accompanying consolidated financial statements have been prepared using accounting principles generally accepted in the United States of America, or “GAAP,” and with the instructions to Form 10-Q and Securities and Exchange Commission Regulation S-X as they apply to interim financial information. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. The balance sheet at December 31, 2012 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by GAAP for complete financial statements.

In the opinion of our management, all adjustments have been included which are necessary to make the financial statements not misleading. All of these adjustments that are material are of a normal and recurring nature. Our operating results for the three months ended March 31, 2013 are not necessarily indicative of the results to be expected for the year ending December 31, 2013. You should read our unaudited interim financial statements together with the financial statements and related footnotes for the year ended December 31, 2012 included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2012. Our Annual Report on Form 10-K for the fiscal year ended December 31, 2012 includes a description of our significant accounting policies.

Revenue Recognition

We recognize revenue at the time we transfer title to our products to our customers consistent with generally accepted accounting principles.  Generally, we recognize revenue when our products are delivered to our customer’s location consistent with our terms of sale.  We recognize revenue for international shipments when title has transferred consistent with standard terms of sale.

We require certain customers, mostly international customers, to pay for product prior to the transfer of title to the customer.  Deposits received from customers and payments in advance for orders are recorded as liabilities under Customer Deposits until such time as orders are filled and title transfers to the customer consistent with our terms of sale.

Cash and Cash Equivalents

We consider cash on hand, money market funds, unrestricted certificates of deposit and short term marketable securities with an original maturity of 90 days or less as cash and cash equivalents.

Research and Product Development

We recognize research and product development expenses as incurred.  We incurred product development and research costs related to the commercial development, patent approval and regulatory approval of new products, including our anemia related iron maintenance drug candidate, Soluble Ferric Pyrophosphate, or SFP, aggregating approximately $12.8 million and $9.4 million for the three months ended March 31, 2013 and 2012, respectively. We are conducting human clinical trials on SFP.  We recognize the costs of the human clinical trials as the costs are incurred and services performed over the duration of the trials.

Net Earnings Per Share

We computed our basic earnings (loss) per share using weighted average shares outstanding for each respective period.  Diluted earnings per share also reflect the weighted average impact from the date of issuance of all potentially dilutive securities, consisting of stock options and common share purchase warrants, unless inclusion would have had an anti-dilutive effect.  The calculation of basic weighted average shares outstanding excludes unvested restricted stock. Actual weighted average shares outstanding used in calculating basic and diluted earnings per share were:
