We do not expect to pay any significant federal or state income tax for 2021 because of the losses recorded during the six months ended June 30, 2021, and net operating loss carry forwards from prior years. Accounting standards require the consideration of a valuation allowance for deferred tax assets if it is “more likely than not” that some component or all the benefits of deferred tax assets will not be realized. As of June 30, 2021, we maintained a full valuation allowance for all deferred tax assets. Based on these requirements, no provision or benefit for income taxes has been recorded. There were no recorded unrecognized tax benefits at the end of the reporting period.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">The Tax Cuts and Jobs Act (the “Act”) was signed into law on December 22, 2017.

We had three separate issuances of equity securities convertible into common stock that qualify under this accounting treatment, (i) the 2011 HealthCor Notes, (ii) the 2012 HealthCor Notes and (iii) the 2014 HealthCor Notes. Because the conversion option and the 2011 HealthCor Warrants on the 2011 HealthCor Notes were originally classified as a liability when issued due to the down round provision and the removal of the provision requiring liability treatment, and subsequently reclassified to equity on December 31, 2011, when the 2011 HealthCor Notes were amended, only the accrued interest capitalized as payment in kind (“PIK”) since reclassification qualifies under this accounting treatment.

The face amount of the 2011 HealthCor Note and 2012 HealthCor Note, and 2014 HealthCor Notes, the Fourteenth Amendment Notes and the Eighth Amendment Notes and all accrued PIK interest also qualify for BCF treatment as discussed above. Under the accounting standards, we determined that the restructuring of the HealthCor notes, pursuant to the terms of the Allonge 3 Amendment Notes, resulted in a troubled debt restructuring. As the future cash flows were greater than the carrying amount of the debt at the date of the amendment, we accounted for the change prospectively using the new effective interest rate. During the six months ended June 30, 2021, and 2020, we recorded a BCF of $<span id="xdx_905_eus-gaap--DebtInstrumentConvertibleBeneficialConversionFeature_c20210101__20210630__srt--CounterpartyNameAxis__custom--HealthCor3Member_zTEsLj5AGYg9" title="Beneficial conversion feature">0</span> and $<span id="xdx_909_eus-gaap--DebtInstrumentConvertibleBeneficialConversionFeature_c20200101__20200630__srt--CounterpartyNameAxis__custom--HealthCor3Member_zpnpqHD53FM8">0</span>, respectively.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Warrants were issued with the Fourth, Fifth, Eighth, Ninth, and Allonge 3 Amendment Notes and the proceeds were allocated to the instruments based on relative fair value as the warrants did not contain any features requiring liability treatment and therefore were classified as equity.
