PART III
NARRATIVE
State below in reasonable detail the reasons why Form 10-K, 11-K,
20-F,10-Q, N-SAR or the transition report portion thereof could not be filed
within the prescribed time period.
The Registrant added a Personal Choice Retirement Account option to the
Keithley Instruments, Inc. Retirement Savings Trust and Plan (the "Plan") effect
January 1, 1997. With a Personal Choice Retirement Account, a Plan participant
may choose to invest in any stock listed on a major U.S. exchange, over 800
mutual funds, bonds and other fixed-income investments, and money market funds.
The addition of this fund option caused the need for a Form 11-K for the first
time. The information to complete the financial statements for the Plan was not
received from the Plan administrator until recently. The Registrant's
accountants will complete their audit of the Plan and the Registrant will file
the required Form 11-K within the fifteen-day extension period.
