Tremendous attention is paid to so-called non-cash items when recasting GAAP-based earnings into a pro forma presentation.
A common statement introducing pro forma measures uses language like: "Excluding restructuring and severance charges, net income was..." There are situations in which unique, one-time costs occur because of organic changes in the organization and/or acquisitions or dispositions.
The reality is that such charges reflect the normal and expected: expansion and contraction of activities, acquisitions and dispositions of assets and recurring modifications classified under the label "restructuring." Several companies have begun referring to such costs as "recurring, non-recurring charges." For pro forma measures to be useful and complement GAAP-based numbers, they must meaningfully reflect only onetime charges.
In the spirit of FAS 131, the usefulness of pro forma measures can be enhanced through disclosure and discussion of the key performance metrics that companies use to manage the business.

Which makes it all the less impressive to hear Steptoe & Johnson report that 5 percent of its practice is pro bono; to hear that Skadden, Arps, Slate, Meagher & Flom figures that, on average, its attorneys devote 3 to 4 percent of their time doing pro bono work that fits within their "broader definition": one that includes serving on the board of directors of a hospital or university.
Worth considering, too, is who these firms put in charge of the pro bono program.
