Under this ASU, an entity should perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount, and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value.

The amendments in this update align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The update is effective for Federated on January 1, 2020, with early adoption permitted, and allows for either the prospective or retrospective adoption method. Management plans to elect the prospective adoption approach, which does not require the restatement of prior years.

Leases

On February 25, 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-02, Leases (Topic 842). The core principle is that a lessee should recognize the assets and liabilities that arise from leases on the balance sheet, while retaining a distinction between financing and operating leases.
