The Company recognized customer relationships of $13.0 million and trade names of $8.1 million related to the acquisition of ScotBilt. The fair value of the customer relationship intangible asset was estimated using the multi-period excess earnings method of the income approach. The fair value of the customer relationship intangible asset was determined based on estimates and assumptions of projected cash flows attributable to the acquired customer relationships, the annual attrition rate of existing customer relationships, the contributory asset charges attributable to the assets that support the customer relationships, such as: (i) net working capital; (ii) property, plant, and equipment; (iii) trade names; and (iv) workforce, with the economic life and the discount rate as determined at the time of the acquisition. The fair value of the trade names intangible asset was estimated using the relief-from-royalty method of the income approach. The fair value of the trade names intangible asset was determined based on estimates and assumptions of the expected life of the intangible asset, the royalty rate, and the discount rate that reflects the level of risk associated with the future cash flows, as determined at the time of the acquisition.

Amortization of intangible assets for the fiscal years ended April 3, 2021, March 28, 2020, and March 30, 2019 was $5.6 million, $5.4 million, and $4.8 million respectively. Estimated amortization expense of intangible assets over the next five years is estimated to be (dollars in thousands):
