The preliminary purchase price allocation represents acquired assets and liabilities at estimated fair value. Fair value for loans and intangibles assets was determined by applying discounted cash flow measurement techniques using significant unobservable (Level 3) inputs. These inputs include estimates of loss rates and prepayment speeds, customer attrition rates, operating costs, alternative funding costs and discount rates. The fair value of other acquired assets and liabilities was determined primarily through the use of significant other observable (Level 2) inputs.

On May 1, 2018, the Company acquired a majority voting interest in Switchgrass Holdings, LLC, a restaurant franchise owner and operator, pursuant to merchant banking regulations and restrictions. The purchase price for the acquisition was $14 million and included $6.7 million of intangible assets.
