For the first nine months of 2019, $0.4 million of one-time income items and $1.2 million of expense refunds was excluded from non-interest income for purposes of this computation. Tangible common equity (also referred to as tangible book value or tangible equity) and tangible assets, are equal to common equity and assets, respectively, less $97.7 million of goodwill and intangible assets as of September 30, 2019. Average tangible equity is equal to average common equity less $98.6 million of average goodwill and intangible assets for the nine months September 30, 2019. We believe that this information is consistent with the treatment by bank regulatory agencies, which exclude intangible assets from the calculation of capital ratios.
