Item 5.           Other Events

Proposed Settlement Agreement

         As  previously  reported,   hearings  before  the  Arizona  Corporation
Commission (the "ACC") on the comprehensive Settlement Agreement between Arizona
Public Service  Company (the  "Company") and various other parties ended in July
1999.  See Note 6 of Notes to Condensed  Financial  Statements  in the Company's
Quarterly  Report on Form 10-Q for the fiscal  quarter  ended June 30, 1999 (the
"June 10-Q").  On August 26, 1999, the ACC Hearing  Officer  assigned to conduct
the hearings on the  Settlement  Agreement  issued a recommended  decision.  The
recommended  decision,  which is attached hereto and incorporated herein by this
reference, would approve the Settlement Agreement with some modifications.

         The following are some of the proposed  changes to major  provisions of
the Settlement Agreement:

o             The  ACC  would  not be  prevented  from  commencing  rate  change
              proceedings   during  the  Agreement  term,   provided  that  such
              proceedings  would not modify stranded cost recovery or reduce the
              rate decreases provided in the Agreement for customer class.

o             The  recommended  decision  would  change the  Company's  proposed
              credits for metering, meter reading and billing, and instead would
              require the use of higher credits proposed by ACC staff.

o             The recommended  decision would limit the Company's  collection of
              costs related to the transfer of generation assets to an affiliate
              to 67% of such costs.

         The ACC is tentatively scheduled to consider this recommendation at its
next regularly scheduled open meeting on September 14, 1999.

Proposed Retail Electric Competition Rules

         As previously reported, in June 1999, ACC oral proceedings were held on
the rules that  provide a  framework  for the  introduction  of retail  electric
competition in Arizona (the "Proposed Rules").  See Note 6 of Notes to Condensed
Financial  Statements  in the June 10-Q.  On August 26,  1999,  the ACC  Hearing
Officer issued a recommended  decision on the Proposed  Rules.  The  recommended
decision  proposes adoption of the Proposed Rules with a number of modifications
which the  recommended  decision  states do not change the Proposed Rules in any
substantive manner.

         The ACC is tentatively scheduled to consider this recommendation at its
next regularly scheduled open meeting on September 14, 1999.
