Basis of Presentation

The unaudited interim condensed consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Rule 10-01 of Regulation S-X.

In the opinion of management, the unaudited interim condensed consolidated financial statements reflect all adjustments, which are of a normal recurring nature, necessary for the fair presentation of financial position, results of operations, and cash flows of Morgan for the interim periods presented and are not necessarily indicative of a full year’s results.

The interim condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, G.research, from the date of the Merger with retrospective application. Intercompany accounts and transactions have been eliminated.
