Full-Year 2015 Outlook
Notes:
(1) Results for 2012 have been adjusted on a retrospective basis to reflect
the impact of the BDNA discontinued operations, including a reallocation
of corporate overhead expenses, and the segment realignment.
(2) The Company has excluded the following from its "as adjusted"
financial measurements: 1) short-term purchase accounting adjustments
and transaction costs related to its Synventive acquisition in 2012, 2)
short-term purchase accounting adjustments and transaction costs related
to its Männer acquisition in 2013, 2014 and 2015, 3) restructuring charges
related to the closure of production operations at the Company’s
Associated Spring facility located in Saline, Michigan in 2014 , 4) CEO
transition costs associated with the modification of outstanding equity
awards in 2013, and 5) the tax charge associated with the April 2013 tax
court decision in 2013.
Management believes that these adjustments provide the Company and
its investors with an indication of our baseline performance excluding
items that are not considered to be reflective of our ongoing results.
Management does not intend results excluding the adjustments to
represent results as defined by GAAP, and the reader should not consider
it as an alternative measurement calculated in accordance with GAAP, or
as an indicator of the Company's performance. Accordingly, the
measurements have limitations depending on their use.
As Barnes Group does not predict special items that may occur in the
future, and because our outlook is developed at a level of detail different
than that used to prepare GAAP-based financial measures, we do not
provide reconciliations to GAAP of our forward-looking financial measures.
