Regulation G Disclosure Statement
This press release includes financial results and guidance for NiSource with respect to net operating earnings available to common shareholders, which is a non-GAAP financial measure as defined by the Securities and Exchange Commission's (SEC) Regulation G. The company includes this measure because management believes it permits investors to view the company's performance using the same tools that management uses and to better evaluate the company's ongoing business performance. With respect to such guidance, it should be noted that there will likely be a difference between this measure and its GAAP equivalent due to various factors, including, but not limited to, fluctuations in weather, the impact of asset sales and impairments, and other items included in GAAP results. The company is not able to estimate the impact of such factors on GAAP earnings and, as such, is not providing earnings guidance on a GAAP basis. In addition, the company is not able to provide a reconciliation of its non-GAAP net operating earnings guidance to its GAAP equivalent without unreasonable efforts.
