[1] The primary items that generate goodwill include the value of the synergies between the acquired company and Oncotelic, Inc. and the acquired assembled workforce, neither of which qualifies for recognition as an intangible asset. Goodwill is the excess of the purchase price over the fair value of the underlying net tangible and identifiable intangible assets. In accordance with applicable accounting standards, goodwill is not amortized but instead is tested for impairment at least annually or more frequently if certain indicators are present. Goodwill and intangibles is not deductible for tax purposes. The Company has considered the valuation as a preliminary allocation of assets and liabilities and may adjust such estimates in the future, if deemed material.
