Non-GAAP Information

In addition to disclosing results determined in accordance with GAAP, CMS may also disclose certain non-GAAP and pro forma non-GAAP results of operations, including net income, earnings per share, and operating income that make certain adjustments or exclude certain charges and gains that are outlined in the schedules included in this website. CMS provides historical financial results on both a GAAP and non-GAAP basis. Management views adjusted earnings as a key measure of the company’s present operating financial performance and uses adjusted earnings for external communications with analysts and investors. Internally, the company uses adjusted earnings to measure and assess performance. Adjustments could include items such as discontinued operations, asset sales, impairments, restructuring costs, regulatory items from prior years, or other items. Because the company is not able to estimate the impact of specific line items, which have the potential to significantly impact, favorably or unfavorably, the company’s reported earnings in future periods, the company is not providing reported earnings guidance nor is it providing a reconciliation for the comparable future period earnings.

CMS and Virtua also take no responsibility for third party pricing data provided for informational purposes and certain ratio results formulated from the provided third party pricing data. The non-GAAP information is not prepared in accordance with GAAP and may not be comparable to non-GAAP information used by other companies. The non-GAAP information should be considered supplemental information to assist in fully understanding our business results, rather than as a substitute for the reported earnings.

A reconciliation of each of these non-GAAP measures to the most directly comparable GAAP measure is included as a separate link and also posted on the CMS website at
