Financial reporting by a development stage enterprise differs from financial reporting for an established operating enterprise in regard to footnote disclosures:

Under U.S. Generally Accepted Accounting Principles (GAAP), a development stage enterprise must follow the same revenue and expense recognition principles as an established operating enterprise. There are no special or different accounting principles for these entities. The historical distinction, as established by the now-superseded SFAS No. 7, was solely in the financial statement disclosures. Development stage enterprises were required to provide additional information in the footnotes, including cumulative financial data (revenues, expenses, net losses) from the entity's inception and a description of their development stage activities. Although the specific "development stage enterprise" designation and its unique disclosure requirements were eliminated by ASU 2014-10, the core principle that all entities use the same recognition criteria remains.

B. Expense recognition principles are the same for both development stage and established enterprises; the difference was not in accounting principles.
C. Revenue recognition principles are the same for both development stage and established enterprises; the difference was not in accounting principles.
D. Both revenue and expense recognition principles are applied uniformly to all enterprises, regardless of their stage of development. ---

Paragraph 10 states, "A development stage enterprise shall use the same generally accepted accounting principles that apply to established operating enterprises..." Paragraph 11 outlines the specific additional disclosures that were required.

2. Financial Accounting Standards Board (FASB). (2014). Accounting Standards Update (ASU) No. 2014-10, Development Stage Entities (Topic 915): Elimination of Certain Financial Reporting Requirements. The summary explains that the update removes the distinction of development stage entities and their specific reporting requirements from GAAP, reinforcing a single set of rules for all entities.

Chapter 4, "Income Statement and Related Information," discusses the fundamental principles of expense and revenue recognition that apply universally to all business entities, supporting the concept that accounting principles are not modified based on an enterprise's operational maturity.
