Item 2.05 Costs Associated with Exit or Disposal Activities.

On August 25, 2009 Keithley Instruments, Inc. issued a press release reporting a reduction in its global workforce by approximately ten percent, which includes the impact of a voluntary separation program.  It is expected that non-recurring severance, separation and related costs associated with the reductions will approximate $2.3 to $2.6 million on a pre-tax basis and that the majority of the charges will be recorded in the fourth quarter ending September 30, 2009.  The majority of the cash expenditures are estimated to be paid within one year by the Company.  The Company’s press release is filed with this Report as Exhibit 99.

“Safe Harbor” Statement under the Private Securities Litigation Reform Act of 1995

Certain of the statements in this Current Report on Form 8-K that are not historical facts, including those relating to cost savings, estimated charges expected to be incurred, sales growth and current expectations of sales and results, are “forward-looking statements,” as defined in the Private Securities Litigation Reform Act of 1995, that involve a number of risks and uncertainties.  Actual results may differ materially from the results stated or implied in the forward-looking statements as a result of a number of factors that include, but are not limited to: worldwide economic conditions; uncertainties in the credit and capital markets; business conditions in the semiconductor, wireless, precision electronics and other segments of the worldwide electronics industry; timing of recognizing shipments to revenue; the Company's ability to develop new products in a timely fashion and gain market acceptance of those products to remain competitive and gain market share; competitive factors, including pricing pressures, loss of key employees, technological developments and new products offered by competitors; and the Company’s ability to implement planned cost savings initiatives and other initiatives to return to profitability without adversely affecting the Company’s product development program and strategic initiatives.  Further information on factors that could cause actual results to differ from those anticipated is included in the Company’s annual report on Form 10-K and quarterly reports on Form 10-Q which are filed with the Securities and Exchange Commission.  In light of these uncertainties, the inclusion of forward-looking information should not be regarded as a representation by the Company that its plans or objectives will be achieved.  Further, the Company is not obligating itself to revise forward-looking statements contained herein to reflect events or circumstances after the date of this release or to reflect the occurrence of unanticipated events.
