Section 2 - Financial Information


Item 2.02 - Results of Operations and Financial Condition

On April 18, 2006,  Standard  Microsystems  Corporation (the "Company") issued a
press release announcing its financial results for its fourth quarter and fiscal
year ended February 28, 2006. A copy of the press release is furnished  herewith
and attached as Exhibit 99.1.

Management of the Company will host a  teleconference  on April 18, 2006 at 5:00
PM eastern  time to discuss the  Company's  results.  Details on  accessing  the
teleconference  are contained in the Company's press release dated April 6, 2006
announcing the  teleconference.  An audio replay of the  teleconference  will be
available  on a 24-hour  basis from April  18-24,  2006 and can be  accessed  by
dialing  1-888-203-1112  and  entering  the  following  passcode:   4095142.  In
addition,  a  webcast  archive  of the  audio  and  slide  presentation  will be
available  on the  investor  relations  portion  of  the  Company's  website  at

Use of Non-GAAP Financial Information

Included  within  the  press  release  are  non-GAAP   financial  measures  that
supplement the Company's  Consolidated  Statements of Operations  prepared under
general accepted accounting principles (GAAP). These non-GAAP financial measures
adjust the  Company's  actual  results  prepared  under GAAP to exclude  certain
charges as more fully described in the accompanying press release.  The non-GAAP
measures  have been  reconciled  to and should be  considered  together with the
Consolidated Statements of Operations.  These non-GAAP measures are not meant as
a substitute for GAAP, but are included solely for informational and comparative
purposes.  The Company's  management  believes that this information  assists in
evaluating  operational  trends, but should not be regarded as a replacement for
corresponding, similarly captioned, GAAP measures.

The information in this Item 2.02 and Item 9.01 and Exhibit 99.1 attached hereto
shall not be  deemed  "filed"  for  purposes  of  Section  18 of the  Securities
Exchange Act of 1934, as amended,  or otherwise  subject to the  liabilities  of
that  section,  nor shall it be deemed  incorporated  by reference in any filing
under  the  Securities  Act of  1933,  as  amended,  regardless  of any  general
incorporation language in such filing.
