we can terminate the amended collaboration agreement if all milestones are not achieved by march 31 , 2015. if all milestones are achieved by march 31 , 2015 and we have not exercised our option , the diagnostics company can terminate the collaboration agreement and pay us a termination fee of approximately $ 1.5 million . the amended collaboration agreement gives us the right to extend the effective date of termination to september 30 , 2015 by making a payment of $ 0.5 million ( the extension fee ) to the diagnostics company . if the extension fee is paid , and we thereafter purchase the outstanding stock of the diagnostics company , then the option price due at closing will be reduced by the amount of the extension fee . the amendment to the collaboration agreement eliminated the diagnostics company 's ability to require us to exercise the option to purchase the outstanding common stock of the diagnostics company . in the fourth quarter of 2014 , the 37 pdi , inc. annual report on form 10-k ( continued ) company identified events that have had an adverse effect on the fair value of this investment and impaired the initial fee of $ 1.5 million . see note 18 , investment in privately held non-controlled entity and other arrangements , to our consolidated financial statements included in this annual report on form 10-k for further information . as of december 31 , 2014 , it was determined that we would not continue to operate group dca and that we would divest this business . see note 7 , goodwill and other intangible assets , and note 19 , discontinued operations , to our consolidated financial statements included in this annual report on form 10-k for further information . in connection with this decision , we are now offering pd one to customers in our commercial services segment and using pd one in our interpace diagnostics segment . pd one is a proprietary technology platform aimed at expanding relationships between pharmaceutical and life science companies and health care providers . the platform enables customers to extend personal and brand interactions with physicians through a secure , professional networking platform that features direct messaging and dynamic content . description of reporting segments effective december 31 , 2014 , we have two reporting segments : commercial services and interpace diagnostics . we realigned our reporting segments , and the operating segments and service offerings within our reporting segments , due to the acquisition of redpath and acquiring certain assets from asuragen , inc. ( asuragen ) to reflect our current and going forward business strategy . as part of our strategy , we have decided to discontinue our edetailing services offering , classified the group dca business as discontinued operations and held for sale , in an effort to reduce spending in the area and focus our resources on our strategic plan . therefore , we will no longer be presenting a marketing services segment . our current reporting segments are reflective of the way our chief operating decision maker views and manages the business . the operating segments or service offerings included in our reporting segments are as follows : ▪ commercial services reporting segment , consists of the following service offerings : personal promotion , through our : ◦ dedicated sales teams ; and ◦ established relationship team . medical and clinical services ; and full product commercialization . ▪ interpace diagnostics reporting segment , which consists of the following operating segments : ▪ gastrointestinal ; and ▪ endocrinology . select financial information for each of these segments is contained in note 17 , segment information , to our consolidated financial statements included in this annual report on form 10-k and in the discussion under “ consolidated results of operations . ” critical accounting policies we prepare our consolidated financial statements in accordance with u.s. generally accepted accounting principles ( gaap ) . the preparation of financial statements and related disclosures in conformity with gaap requires management to make judgments , estimates and assumptions at a specific point in time that affect the amounts reported in our consolidated financial statements and disclosed in the accompanying notes . these assumptions and estimates are inherently uncertain . outlined below are accounting policies , which are important to our financial position and results of operations , and require our management to make significant judgments in their application . some of those judgments can be subjective and complex . management 's estimates are based on historical experience , information from third-party professionals , facts and circumstances available at the time and various other assumptions that are believed to be reasonable . actual results could differ from those estimates . additionally , changes in estimates could have a material impact on our consolidated results of operations in any one period . for a summary of all of our significant accounting policies , including the accounting policies discussed below , see note 1 , nature of business and significant account policies , to our consolidated financial statements included in this annual report on form 10-k. revenue and cost of services we recognize revenue from services rendered when the following four revenue recognition criteria are met : persuasive evidence of an arrangement exists ; services have been rendered ; the selling price is fixed or determinable ; and collectability is reasonably assured . our contracts containing multiple deliverables are accounted for in accordance with accounting standards codification ( asc ) 605-25 , revenue recognition : multiple element arrangements . 38 pdi , inc. annual report on form 10-k ( continued ) commercial services revenue under commercialization services contracts is generally based on the number of sales representatives utilized or the number of physician details made and , when applicable , the full commercial operations services provided . story_separator_special_tag contingencies are recorded in the consolidated financial statements when it is probable that a liability will be incurred and the amount of the loss can be reasonably estimated , or otherwise disclosed , in accordance with asc 450 , contingencies . significant judgment is required in both the determination of probability and the determination as to whether a loss is reasonably estimable . in the event we determine that a loss is not probable , but is reasonably possible , and it becomes possible to develop what we believe to be a reasonable range of possible loss , then we will include disclosures related to such matter as appropriate and in compliance with asc 450. to the extent there is a reasonable possibility that the losses could exceed the amounts already accrued , we will , when applicable , adjust the accrual in the period the determination is made , disclose an estimate of the additional loss or range of loss , indicate that the estimate is immaterial with respect to its financial statements as a whole or , if the amount of such adjustment can not be reasonably estimated , disclose that an estimate can not be made . we are currently involved in certain legal proceedings and , as required , have accrued our estimate of the probable costs for the resolution of these claims . these estimates are developed in consultation with outside counsel and are based upon an analysis of potential results , assuming a combination of litigation and settlement strategies . predicting the outcome of claims and litigation , and estimating related costs and exposures , involves substantial uncertainties that could cause actual costs to vary materially from estimates . income taxes income taxes are based on income for financial reporting purposes calculated using our expected annual effective rate and reflect a current tax liability or asset for the estimated taxes payable or recoverable on the current year tax return and expected annual changes in deferred taxes . we account for income taxes using the asset and liability method . this method requires recognition of deferred tax assets and liabilities for expected future tax consequences of temporary differences that currently exist between tax bases and financial reporting bases of our assets and liabilities based on enacted tax laws and rates . deferred tax expense ( benefit ) is the result of changes in the deferred tax asset and liability . a valuation allowance is established , when necessary , to reduce the deferred income tax assets when it is more likely than not that all or a portion of a deferred tax asset will not be realized . we operate in multiple tax jurisdictions and provide taxes in each jurisdiction where we conduct business and are subject to taxation . the breadth of our operations and the complexity of the various tax laws require assessments of uncertainties and judgments in estimating the ultimate taxes we will pay . the final taxes paid are dependent upon many factors , including negotiations with taxing authorities in various jurisdictions , outcomes of tax litigation and resolution of proposed assessments arising from federal and state audits . we have established estimated liabilities for uncertain federal and state income tax positions . uncertain tax positions are recognized in the financial statements when it is more likely than not ( for example , a likelihood of more than fifty percent ) that a position taken or expected to be taken in a tax return would be sustained upon examination by tax authorities that have full knowledge of all relevant information . a recognized tax position is then measured as the largest amount of benefit that is greater than fifty percent likely to be realized upon ultimate settlement . we adjust our accruals for unrecognized tax benefits as facts and circumstances change , such as the progress of a tax audit . we believe that any potential audit adjustments will not have a material adverse effect on our financial condition or liquidity . however , any adjustments made may be material to our consolidated results of operations or cash flows for a reporting period . penalties and interest , if incurred , would be recorded as a component of current income tax expense . significant judgment is also required in evaluating the need for and magnitude of appropriate valuation allowances against deferred tax assets . we currently have significant deferred tax assets resulting from net operating loss carryforwards and deductible temporary differences . the realization of these assets is dependent on generating future taxable income . we perform an analysis quarterly to determine whether the expected future income will more likely than not be sufficient to realize the deferred tax assets . our recent operating results and projections of future income weighed heavily in our overall assessment . the existing and forecasted levels of pretax earnings for financial reporting purposes are not sufficient to generate future taxable income and realize our deferred tax assets and , as a result , we established a full federal and state valuation allowance for the net deferred tax assets at december 31 , 2014 and 2013 , as we determined that it was more likely than not that these assets would not be realized . 42 pdi , inc. annual report on form 10-k ( continued ) stock compensation costs the compensation cost associated with the granting of stock-based awards is based on the grant date fair value of the stock award . we recognize the compensation cost , net of estimated forfeitures , over the shorter of the vesting period or the period from the grant date to the date when retirement eligibility is achieved . forfeitures are initially estimated based on historical information and subsequently updated over the life of the awards to ultimately reflect actual forfeitures . as a result , changes in forfeiture activity can influence the amount of stock compensation cost recognized from period-to-period . we primarily use the black-scholes option
