Accordingly, these interim financial statements do not include all of the information and footnotes required for annual financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary to make the financial statements not misleading have been included.   The operating results for the six month period ended June 30, 2013 are not necessarily indicative of the results that may be expected for the year ending December 31, 2013. These financial statements should be read in conjunction with the financial statements and footnotes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2012, filed with the Securities and Exchange Commission on April 16, 2013.   Use of Estimates   The preparation of consolidated 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, liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period.   Management bases its estimates on historical experience and on various assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. The most significant estimates, among other things, are used in accounting for allowances for deferred income taxes, expected realizable values for long-lived assets (primarily intangible assets and property and equipment), contingencies, as well as the recording and presentation of its common stock.  Estimates and assumptions are periodically reviewed and the effects of any material revisions are reflected in the consolidated financial statements in the period that they are determined to be necessary. Actual results could differ from those estimates and assumptions.   Principles of Consolidation   The consolidated financial statements of PureSafe Water Systems, Inc. include accounts of the Company and its wholly-owned subsidiary, PureSafe Manufacturing and Research Corporation. Intercompany transactions and balances are eliminated in consolidation.   Revenue Recognition   The Company generally recognizes revenues under Staff Accounting Bulletin No. 104 when the following criteria are met, persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the seller's price to the buyer is fixed or determinable, and collectibility is reasonably assured. In addition the Company may enter agreements that include multiple elements (i.e., products and services/training).  Revenue under multiple element arrangements is recognized in accordance with FASB ASC 605-25 Multiple-Element Arrangements (ASC 605).  When vendor specific objective evidence or third party evidence of selling price for deliverables in an arrangement cannot be determined, the Company develops a best estimate of the selling price to separate deliverables and allocates arrangement consideration using the relative selling price method. Additionally, this guidance eliminates the residual method of allocation.  If an arrangement includes undelivered elements that are not essential to the functionality of the delivered elements, we defer the fair value of the undelivered elements with the residual revenue allocated to the delivered elements. Fair value is determined based upon the price charged when the element is sold separately. If there is not sufficient evidence of the fair value of the undelivered elements, no revenue is allocated to the delivered elements and the total consideration received is deferred until delivery of those elements for which objective and reliable evidence of the fair value is not available.  For the six months ended June 30, 2013and 2012, the Company did not have any multiple deliverable elements.   Inventories   Inventory amounts are stated at lower of first-in, first-out (FIFO) cost or market.   Deferred Financing Costs   Cost incurred in conjunction with the debt financing has been capitalized and will be amortized to interest expense using the straight line method, which approximates the interest rate method over the term of the debt and is included as a component of other assets.   Derivative Liabilities   In connection with the issuance of certain convertible promissory notes, the terms of the convertible notes included an embedded conversion feature; which provided for the settlement of certain convertible promissory notes into shares of common stock at a rate which was determined to be variable.  The Company determined that the conversion feature was an embedded derivative instrument pursuant to ASC 815 Derivatives and Hedging   The accounting treatment of derivative financial instruments requires that the Company record the conversion option and related warrants at their fair values as of the inception date of the agreements and at fair value as of each subsequent balance sheet date.  As a result of entering into the convertible promissory notes, the Company is required to classify all other non-employee warrants as derivative liabilities and record them at their fair values at each balance sheet date.  Any change in fair value was recorded as a change in the fair value of derivative liabilities for each reporting period at each balance sheet date.  The Company reassesses the classification at each balance sheet date.  If the classification changes as a result of events during the period, the contract is reclassified as of the date of the event that caused the reclassification.   The fair value of conversion options that are convertible at a fixed number of shares or at a fixed conversion price are recorded using the intrinsic value method and conversion options at variable rates are deemed to be a down-round protection and therefore, do not meet the scope exception for treatment as a derivative under ASC 815.  Since, down-round protection is not an input into the calculation of the fair value of the conversion option and cannot be considered indexed to the Companys own stock which is a requirement for the scope exception as outlined under ASC 815. The Company determined the fair value of the Binomial Lattice Model and the Intrinsic Value Method to be materially the same. Warrants that have been reclassified to derivative liability that did not contain down-round protection were valued using the  black-scholes model. The Companys outstanding warrants did not contain any down round protection.   The Black-Scholes option valuation model is used to estimate the fair value of the warrants or options granted.  The model includes subjective input assumptions that can materially affect the fair value estimates.  The model was developed for use in estimating the fair value of traded options or warrants.  The expected volatility is estimated based on the most recent historical period of time equal to the weighted average life of the warrants or options granted   The principal assumptions used in applying the Black-Scholes model were as follows:   <table cellspacing="0" cellpadding="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%"> <tr style="vertical-align: bottom"> <td style="padding-bottom: 1.5pt"> </td> <td style="padding-bottom: 1.5pt"> </td> <td colspan="2" style="border-bottom: black 1.5pt solid"> For the six months ended June 30, 2013</td> <td nowrap="nowrap" style="padding-bottom: 1.5pt"> </td></tr> <tr style="vertical-align: bottom"> <td>Assumptions:</td> <td> </td> <td colspan="2"> </td> <td nowrap="nowrap"> </td></tr> <tr style="vertical-align: bottom; background-color: #CCEEFF"> <td style="width: 89%">Risk-free interest rate</td> <td style="width: 1%; text-align: right"> </td> <td style="width: 1%"> </td> <td style="width: 8%; text-align: right">0.36%- 1.96 </td> <td nowrap="nowrap" style="width: 1%">%</td></tr> <tr style="vertical-align: bottom; background-color: white"> <td>Expected life</td> <td style="text-align: right"> </td> <td> </td> <td style="text-align: right">3</td> <td nowrap="nowrap"> </td></tr> <tr style="vertical-align: bottom; background-color: #CCEEFF"> <td>Expected volatility</td> <td style="text-align: right"> </td> <td> </td> <td style="text-align: right">125%-175 </td> <td nowrap="nowrap">%</td></tr> <tr style="vertical-align: bottom; background-color: white"> <td>Dividends</td> <td style="text-align: right"> </td> <td> </td> <td style="text-align: right">0.0 </td> <td nowrap="nowrap">%</td></tr> </table>   Stock-Based Compensation   The Company reports stock-based compensation under Accounting Standard Codification (ASC) 718 Compensation Stock Compensation.  ASC 718 requires all share-based payments to employees, including grants of employee stock options, to be recognized in the consolidated financial statements based on their fair values.   The Company accounts for equity instruments issued to non-employees as compensation in accordance with the provisions of ASC 718, which require that each such equity instrument is recorded at its fair value on the measurement date, which is typically the date the services are performed.   The Black-Scholes option valuation model is used to estimate the fair values of options. The model includes subjective input assumptions that can materially affect the fair value estimates. The model was developed for use in estimating the fair value of traded options or warrants. The expected volatility is estimated based on the most recent historical period of time equal to the weighted average life of the subject options or warrants.   The principal assumptions used in applying the Black-Scholes model were as follows:   <table cellspacing="0" cellpadding="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%"> <tr style="vertical-align: bottom"> <td style="padding-bottom: 1.5pt"> </td> <td style="padding-bottom: 1.5pt"> </td> <td colspan="2" style="border-bottom: black 1.5pt solid"> For the six months ended June 30, 2013</td> <td style="padding-bottom: 1.5pt"> </td></tr> <tr style="vertical-align: bottom"> <td>Assumptions:</td> <td> </td> <td colspan="2"> </td> <td> </td></tr> <tr style="vertical-align: bottom; background-color: #CCEEFF"> <td style="width: 89%">Risk-free interest rate</td> <td style="width: 1%"> </td> <td style="width: 1%"> </td> <td style="width: 8%; text-align: right">0.36 - 1.96</td> <td style="width: 1%">%</td></tr> <tr style="vertical-align: bottom; background-color: white"> <td>Expected life</td> <td> </td> <td> </td> <td style="text-align: right">3</td> <td> </td></tr> <tr style="vertical-align: bottom; background-color: #CCEEFF"> <td>Expected volatility</td> <td> </td> <td> </td> <td style="text-align: right">125% - 175</td> <td>%</td></tr> <tr style="vertical-align: bottom; background-color: white"> <td>Dividends</td> <td> </td> <td> </td> <td style="text-align: right">0.0</td> <td>%</td></tr> </table>falsefalsefalsenonnum:textBlockItemTypenaThe entire disclosure for the basis of presentation and significant accounting policies concepts.
