On December 16, 2020, we acquired all the issued and outstanding equity of Arktura LLC (“Arktura”) and its subsidiaries with operations in the United States and Argentina for $90.6 million of cash paid at closing, net of $0.8 million of cash acquired, subject to customary post-closing adjustments for working capital. A portion of the cash consideration paid at closing is being held in escrow to secure potential claims for indemnification under the agreement. Under the terms of the agreement, and contingent upon continued employment with AWI over the next five years, we are obligated to pay the sellers an additional $24.0 million in cash payments over a period of five years and issued an additional $6.0 million of restricted stock which will vest over a period of five years. Contingent upon employment with AWI over the next three years, we also issued an additional $1.4 million of restricted stock to key Arktura employees which will vest over a period of three years. Compensation expense associated with these cash payments and restricted stock awards will be recorded over the required service and vesting periods.

The total fair value of tangible assets acquired, less liabilities assumed, was $4.1 million. The total fair value of identifiable intangible assets acquired was $36.2 million, resulting in $51.1 million of goodwill. We identified non-amortizable tradenames of $14.5 million. We also identified amortizable intangible assets comprised of software of $9.1 million, backlog of $5.9 million, customer relationships of $3.3 million, a non-compete agreement of $2.8 million and patents of $0.6 million that are being amortized on a straight-line basis over a weighted average life of 7, 1, 1, 5, and 17 years, respectively. The weighted average amortization period for acquired intangible assets as of the date of acquisition was 4.3 years. Goodwill from the Arktura acquisition relates to many factors, including the technical competencies and capabilities of the acquired workforce in the fields of architecture, design, materials science, technology and software, and our strategic intent to integrate and leverage those competencies and capabilities to advance and expand our portfolio of solutions and offerings. All of the acquired goodwill is deductible for tax purposes.

Valuations for assets acquired and liabilities assumed are based on provisional estimates. We will continue to evaluate the fair value of assets acquired and liabilities assumed related to the acquisition. Additional information, which existed as of the acquisition date, but was at that time unknown to us, may become known during the remainder of the measurement period. Changes to amounts recorded may result in a corresponding adjustment to these assets and liabilities, including goodwill. The determination of the estimated fair values of all assets acquired and liabilities assumed is expected to be completed within one year from the date of acquisition.

In connection with the Arktura acquisition, we formed Arktura Ventures LLC, an incubator entity for the development and commercialization of new products and solutions in the architecture, engineering and construction space. As of December 31, 2020, the venture entity had no funding or operations.

On August 24, 2020, we acquired the business and assets of Moz for $4.2 million of cash paid at closing and the potential for a contingent earn out payable in 2022 not to exceed $4.7 million. We, with the assistance of an independent, third-party valuation specialist, utilized a Monte Carlo simulation to determine the estimated fair value of the contingent consideration of $2.7 million, resulting in total acquisition consideration of $6.9 million. The total fair value of liabilities assumed, less tangible assets acquired, was $0.4 million. The total fair value of identifiable intangible assets acquired was $2.7 million, comprised of non-amortizable tradenames of $1.5 million, amortizable customer relationships of $0.6 million and backlog of $0.6 million, resulting in $4.6 million of goodwill. All of the acquired goodwill is deductible for tax purposes. The contingent consideration is payable upon achievement of certain future performance objectives through December 31, 2021. See Note 19 for changes in fair value of contingent consideration.

On July 27, 2020, we acquired all the issued and outstanding capital stock of Turf for a purchase price of $70.0 million of cash paid at closing and the potential for a contingent earn out payable in 2022 and 2023 not to exceed $48.0 million. We, with the assistance of an independent, third-party valuation specialist, utilized a Monte Carlo simulation to determine the estimated fair value of the contingent consideration of $14.1 million, resulting in total acquisition consideration of $84.1 million. The total fair value of tangible assets acquired, less liabilities assumed, was $4.8 million. The total fair value of identifiable intangible assets acquired was $27.9 million, resulting in $51.4 million of goodwill. We identified non-amortizable tradenames of $9.6 million. We also identified amortizable intangible assets comprised of customer relationships of $7.7 million, patents of $5.8 million and a non-compete agreement of $3.3 million that are being amortized on a straight-line basis over a weighted average life of 2, 20, and 5 years, respectively. The weighted average amortization period for acquired intangible assets as of the date of acquisition was 8.3 years. Goodwill from the Turf acquisition relates to many factors, including the design talents of the acquired workforce, fabrication capabilities and capacity, broad-based go-to-market channels and relationships, established leadership in a growing product category, and our strategic intent to leverage its position and attributes to grow and expand our portfolio of solutions. All of the acquired goodwill is deductible for tax purposes.

The contingent consideration is payable upon achievement of certain future performance objectives through 2022. The contingent consideration includes up to $24.0 million in additional cash consideration for performance at certain revenue and earnings before interest, taxes, depreciation and amortization (“EBITDA”) growth targets. Full payout for target performance requires compounded annual growth rates in excess of 23% through December 31, 2022. The contingent consideration also includes up to $24.0 million in additional cash consideration for performance over revenue and EBITDA growth targets. Full payout for achievement over target performance requires compounded annual growth rates in excess of 38% through December 31, 2022. See Note 19 for changes in fair value of contingent consideration.

The following table summarizes aggregate audited as reported information and aggregate unaudited pro forma information assuming the acquisitions of Arktura, Moz and Turf had occurred on January 1, 2018.
