however , actual results may differ from these estimates and assumptions . if our judgment or interpretation of the facts and circumstances relating to the various transactions had been different , it is possible that different accounting policies would have been applied , thus resulting in a different presentation of the financial statements . additionally , other companies may utilize different assumptions or estimates that may impact comparability of our results of operations to those of companies in similar businesses . we believe the following critical accounting policies govern the significant judgments and estimates used in the preparation of our financial statements , which should be read in conjunction with the more complete discussion of our accounting policies and procedures included in “ note 2 – summary of significant accounting policies ” to our consolidated financial statements . 33 goodwill impairment we evaluate goodwill for impairment annually or more frequently when an event occurs or circumstances change that indicate the carrying value may not be recoverable . we adopted asu 2017-04 , intangibles – goodwill and others ( topic 350 ) : simplifying the test for goodwill impairment ( “ asu 2017-04 ” ) , which simplifies the measurement of goodwill impairment by eliminating step 2 from the goodwill impairment test ( comparing the implied fair value of goodwill with the carrying amount of goodwill ) . the risks and uncertainties involved in applying the principles related to goodwill impairment include , but are not limited to , the following : we estimate the fair value using discounted cash flows and relevant competitor multiples . we monitor factors that may impact the fair value including market comparable company multiples , interest rates and global economic conditions . we use a combined income and market approach in evaluations for potential impairment , which requires management to make key assumptions related to revenue growth rate , cash flow assumptions , discount rate and selection of comparable companies . see “ note 9 – fair value measures ” for discussion regarding our sensitivity analysis performed around these assumptions . real estate investment impairment we invest in real estate assets and subsequently monitor those investments quarterly for impairment , including the review of real estate properties subject to direct financing leases . additionally , we record depreciation and amortization related to our investments . the risks and uncertainties involved in applying the principles related to real estate investments include , but are not limited to , the following : the estimated useful lives of our depreciable assets affect the amount of depreciation and amortization recognized on our investments . the review of impairment indicators and subsequent determination of the undiscounted future cash flows could require us to reduce the value of assets and recognize an impairment loss . the fair value of held for sale assets is estimated by management . this estimated value could result in a reduction of the carrying value of the asset . changes in assumptions based on actual results may have a material impact on the company 's financial results . loans held for investment impairment we evaluate loans held for investment on a quarterly basis . as a first step in the notes receivable impairment process , we must determine , based on current information and events , if it is probable that we will be unable to collect the amounts due in accordance with the loan agreement . the risks and uncertainties involved in applying the principles related to notes receivable include , but are not limited to , the following : evaluating the financial condition and other current obligations of the borrower involves judgment in assessing their liquidity and financial stability . allocation of purchase price of real estate assets in connection with our acquisition of properties , we allocate the purchase price to the tangible and intangible assets and liabilities acquired based on their respective estimated fair values . tangible assets consist of land , buildings , fixtures and tenant improvements . intangible assets consist of above- and below- market lease values and the value of in-place leases . our purchase price allocations are developed utilizing third-party appraisal reports , industry standards and management experience . the risks and uncertainties involved in applying the principles related to purchase price allocations include , but are not limited to , the following : the value allocated to land as opposed to buildings , fixtures and tenant improvements affects the amount of depreciation expense we record . if more value is attributed to land , depreciation expense is lower than if more value is attributed to buildings , fixtures and tenant improvements ; intangible lease assets and liabilities can be significantly affected by estimates , including market rent , lease term including renewal options at rental rates below estimated market rental rates , carrying costs of the property during a hypothetical expected lease-up period , and current market conditions and costs , including tenant improvement allowances and rent concessions ; and we determine whether any financing assumed is above- or below- market based upon comparison to similar financing terms for similar investment properties . 34 income taxes as a reit , the general partner generally is not subject to federal income tax on taxable income that it distributes to its shareholders as long as it distributes at least 90 % of its annual taxable income ( computed without regard to the deduction for dividends paid and excluding net capital gains ) , with the exception
