(a)  The net effect on net  electric  operating  revenues  from  realization  of
     prior-period  mark-to-market  included in line 37 is zero.  Realization  of
     prior-period  mark-to-market relates to cash flow recognition,  not revenue
     recognition.  The arithmetic  opposites of amounts  included in line 32 are
     included in lines 28 and 31. For example, line 32 shows that a prior-period
     mark-to-market  gain of $8 million was  transferred  to "realized"  for the
     second quarter of 2002. Lines 28 and 31 include amounts totaling $8 million
     of realized revenues for the second quarter of 2002.

FUTURE MARKETING AND TRADING MARK-TO-MARKET REALIZATION

As of June 30, 2002,  Pinnacle West had accumulated  mark-to-market net gains of
$133 million related to our power marketing and trading activities.  We estimate
that these  gains  will be  reclassified  to  realized  gains as the  underlying
commodities are delivered, as follows: remainder of 2002, $12 million; 2003, $28
million; 2004, $29 million; 2005 and thereafter, $64 million.

----------
(a)  The net effect on pretax  gross  margin from  realization  of  prior-period
     mark-to-market  included in line 57 and in line 61 is zero.  Realization of
     prior-period mark-to-market relates to cash flow recognition,  not earnings
     recognition.  The arithmetic  opposites of amounts  included in line 53 are
     included  in line 49.  The  opposites  of amounts  included  in line 54 are
     included  in line  51.  For  example,  line 53  shows  that a  prior-period
     mark-to-market  gain of $9 million was  transferred  to "realized"  for the
     second  quarter of 2002. A $9 million  realized gain is included in the $24
     million on line 49 for the second quarter of 2002.
(b)  Quarterly  amounts do not total to the annual amounts because of intra-year
     mark-to-market eliminations.

(a)  The net effect on net  electric  operating  revenues  from  realization  of
     prior-period  mark-to-market  included in line 37 is zero.  Realization  of
     prior-period  mark-to-market relates to cash flow recognition,  not revenue
     recognition.  The arithmetic  opposites of amounts  included in line 32 are
     included in lines 28 and 31. For example, line 32 shows that a prior-period
     mark-to-market  gain of $8 million was  transferred  to "realized"  for the
     second quarter of 2002. Lines 28 and 31 include amounts totaling $8 million
     of realized revenues for the second quarter of 2002.

FUTURE MARKETING AND TRADING MARK-TO-MARKET REALIZATION

As of June 30, 2002,  Pinnacle West had accumulated  mark-to-market net gains of
$133 million related to our power marketing and trading activities.  We estimate
that these  gains  will be  reclassified  to  realized  gains as the  underlying
commodities are delivered, as follows: remainder of 2002, $12 million; 2003, $28
million; 2004, $29 million; 2005 and thereafter, $64 million.

----------
(a)  The net effect on pretax  gross  margin from  realization  of  prior-period
     mark-to-market  included in line 57 and in line 61 is zero.  Realization of
     prior-period mark-to-market relates to cash flow recognition,  not earnings
     recognition.  The arithmetic  opposites of amounts  included in line 53 are
     included  in line 49.  The  opposites  of amounts  included  in line 54 are
     included  in line  51.  For  example,  line 53  shows  that a  prior-period
     mark-to-market  gain of $9 million was  transferred  to "realized"  for the
     second  quarter of 2002. A $9 million  realized gain is included in the $24
     million on line 49 for the second quarter of 2002.
(b)  Quarterly  amounts do not total to the annual amounts because of intra-year
     mark-to-market eliminations.

----------
(a)  The net effect on net electric operating revenues from realization of
     prior-period mark-to-market included in line 37 is zero. Realization of
     prior-period mark-to-market relates to cash flow recognition, not revenue
     recognition. The arithmetic opposites of amounts included in line 32 are
     included in lines 28 and 31. For example, line 32 shows that a prior-period
     mark-to-market gain of $1 million was transferred to "realized" for the
     total year 2001. Lines 28 and 31 include amounts totaling $1 million of
     realized revenues for the year 2001.

FUTURE MARKETING AND TRADING MARK-TO-MARKET REALIZATION

As of December 31, 2001, Pinnacle West had accumulated mark-to-market net gains
of $138.0 million related to our power marketing and trading activities. We
estimate that these gains will be reclassified to realized gains as the
underlying commodities are delivered, as follows: 2002, $43.0 million; 2003,
$22.6 million; 2004, $23.6 million; 2005 and thereafter, $48.8 million.

----------
(a)  The net effect on pretax gross margin from realization of prior-period
     mark-to-market included in line 57 and in line 61 is zero. Realization of
     prior-period mark-to-market relates to cash flow recognition, not earnings
     recognition. The arithmetic opposites of amounts included in line 53 are
     included in line 49. The opposites of amounts included in line 54 are
     included in line 51. For example, line 53 shows that a prior-period
     mark-to-market gain of $11 million was transferred to "realized" for the
     total year 2001. A $11 million realized gain is included in the $117
     million on line 49 for the total year 2001.
(b)  Quarterly amounts do not total to the annual amounts because of intra-year
     mark-to-market eliminations.

----------
(a)  The net effect on net electric operating revenues from realization of
     prior-period mark-to-market included in line 37 is zero. Realization of
     prior-period mark-to-market relates to cash flow recognition, not revenue
     recognition. The arithmetic opposites of amounts included in line 32 are
     included in lines 28 and 31. For example, line 32 shows that a prior-period
     mark-to-market gain of $2 million was transferred to "realized" for the
     total year 2000. Lines 28 and 31 include amounts totaling $2 million of
     realized revenues for the year 2000.

----------
(a)  The net effect on pretax gross margin from realization of prior-period
     mark-to-market included in line 57 and in line 61 is zero. Realization of
     prior-period mark-to-market relates to cash flow recognition, not earnings
     recognition. The arithmetic opposites of amounts included in line 53 are
     included in line 49. The opposites of amounts included in line 54 are
     included in line 51. For example, line 53 shows that a prior-period
     mark-to-market gain of $2 million was transferred to "realized" for the
     total year 2000. A $2 million realized gain is included in the $69 million
     on line 49 for the total year 2000.
(b)  Quarterly amounts do not total to the annual amounts because of intra-year
     mark-to-market eliminations.

----------
(a)  The net effect on net electric operating revenues from realization of
     prior-period mark-to-market included in line 37 is zero. Realization of
     prior-period mark-to-market relates to cash flow recognition, not revenue
     recognition. The arithmetic opposites of amounts included in line 32 are
     included in lines 28 and 31. For example, line 32 shows that a prior-period
     mark-to-market gain of $0 million was transferred to "realized" for the
     total year 1999. Lines 28 and 31 include amounts totaling $0 million of
     realized revenues for the year 1999.

     amounts also included some marketing and trading activities in 2001,

BUSINESS SEGMENTS

     We have two principal business segments (determined by products, services
and the regulatory environment), which consist of our regulated retail
electricity business, regulated traditional wholesale electricity business, and
related activities (electric retail business segment) and our competitive
business activities (marketing and trading business segment). Our retail
business segment currently includes activities related to electricity
transmission and distribution, as well as electricity generation. Our marketing
and trading business
<PAGE>
segment currently includes activities related to wholesale marketing and trading
and APSES' competitive energy services. The other amounts include activities
related to SunCor and El Dorado.

We recorded the cumulative effects of a change in accounting for derivatives
related to our adoption in 2001 of Statement of Financial Accounting Standards
(SFAS) No. 133, "Accounting for Derivative Instruments and Hedging Activities."

EARNINGS VARIANCE EXPLANATIONS

     Throughout these explanations, we refer to "gross margin." With respect to
our electric retail segment and marketing and trading segment, gross margin
refers to electric operating revenues less purchased power and fuel costs. Real
estate gross margin refers to real estate revenues less real estate operations
costs.

     OPERATING RESULTS - THREE-MONTH PERIOD ENDED JUNE 30, 2002 COMPARED WITH
     THREE-MONTH PERIOD ENDED JUNE 30, 2001

     Our consolidated net income for the three months ended June 30, 2002 was
$75 million compared with $67 million for the same period in the prior year. The
period-to-period increase was primarily the result of increased earnings
contributions from our regulated retail electricity and real estate operations
that were partially offset by lower earnings contributions from our marketing
and trading activities. The retail comparison was favorably impacted by lower
replacement costs for power plant outages, lower costs for purchased power and
gas related to lower market prices, customer growth and higher average usage per
customer, partially offset by the effects of milder weather. The real estate
results benefited primarily from more sales activities. The comparison for
marketing and trading activities reflects lower volumes and prices in the
wholesale power markets in the western United States.

ELECTRIC RETAIL SEGMENT GROSS MARGIN

     Revenues related to our regulated retail and wholesale electricity
businesses were $242 million lower in the three-month period ended June 30,
2002, compared to the same period in the prior year as a result of:

     *    decreased revenues related to traditional wholesale sales as a result
          of lower sales volumes and lower prices ($54 million);
     *    decreased revenues related to retail load hedge management wholesale
          sales, as a result of lower sales volumes and lower prices ($171
          million);
     *    decreased retail revenues related to milder weather ($26 million);
     *    increased retail revenues related to customer growth and higher
          average usage, excluding weather effects ($21 million);
     *    decreased retail revenues related to a reduction in retail electricity
          prices ($7 million); and
     *    other miscellaneous factors ($5 million net decrease).

     Electric retail segment purchased power and fuel costs were $330 million
lower in the three-month period ended June 30, 2002, compared to the same period
in the prior year as a result of:

     *    decreased costs related to traditional wholesale sales as a result of
          lower sales volumes and lower prices ($54 million);
     *    decreased costs related to lower prices for hedged natural gas and
          purchased power ($217 million);
     *    decreased costs related to the effects of milder weather on retail
          sales ($10 million);
     *    increased costs related to retail sales growth excluding weather
          effects ($9 million); and
     *    decreased replacement power costs for power plant outages due to lower
          market prices and fewer unplanned outages ($58 million).

MARKETING AND TRADING SEGMENT GROSS MARGIN

     Marketing and trading segment revenues were $373 million lower in the
three-month period ended June 30, 2002, compared to the same period in the prior
year as a result of:

     *    decreased revenues from generation sales other than native load due to
          lower market prices and resulting lower sales volumes ($49 million);
     *    decreased realized revenues from other realized marketing and trading
          in the current period primarily due to lower prices ($277 million);
     *    change in prior period mark-to-market gains on contracts delivered
          during the current period due to higher volumes being delivered ($13
          million decrease); and
     *    lower mark-to-market gains for future period deliveries primarily as a
          result of lower market liquidity and lower price volatility, resulting
          in lower volumes ($34 million).

     Marketing and trading segment purchased power and fuel costs were $294
million lower in the three-month period ended June 30, 2002, compared to the
same period in the prior year as a result of:

                                       4
<PAGE>
     *    decreased fuel costs related to generation sales other than native
          load primarily because of lower sales volumes and lower natural gas
          prices ($23 million); and
     *    decreased purchased power costs related to other realized marketing
          and trading in the current period primarily due to lower prices ($271
          million).

     The increase in real estate gross margin of $13 million was primarily due
to increased sales activities.

     The decrease in operations and maintenance expense of $3 million was due to
lower costs related to generation reliability, plant outages and maintenance
costs. Operations and maintenance expense was also lower as a result of the
reversal of $4 million of a $10 million reserve for the California energy
situation. These factors were partially offset with increased employee and other
costs.

     The decrease in depreciation and amortization expense of $4 million
primarily related to lower regulatory asset amortization, in accordance with
APS' 1999 regulatory settlement, partially offset by increased depreciation on
higher plant balances.

     Net other income (expense) decreased $11 million primarily due to an
insurance recovery recorded in the prior period related to environmental
remediation costs and losses recorded on El Dorado's investments in the current
period, partially offset by lower miscellaneous non-operating costs.

     OPERATING RESULTS - SIX-MONTH PERIOD ENDED JUNE 30, 2002 COMPARED WITH
     SIX-MONTH PERIOD ENDED JUNE 30, 2001

     Our consolidated net income for the six months ended June 30, 2002 was $129
million compared with $126 million for the same period in the prior year. We
recognized a $3 million after-tax loss in the six months ended June 30, 2001 as
a cumulative effect of a change in accounting for derivatives, as required by
SFAS No.133.

     Our income before accounting change for the six months ended June 30, 2002
and 2001 was $129 million in both periods. The period-to-period activity was the
result of increased earnings contributions from our regulated retail electricity
and real estate operations that were partially offset by lower earnings
contributions from our marketing and trading activities. The retail comparison
was favorably impacted by lower replacement costs for power plant outages, lower
costs for purchased power and gas related to lower market prices, customer
growth and higher average usage per customer, partially offset by the effects of
milder weather and a retail electricity price decrease. The real estate results
benefited primarily from more sales activities. The comparison for marketing and
trading activities reflects lower volumes and prices in the wholesale power
markets in the western United States.

MARKETING AND TRADING SEGMENT GROSS MARGIN

     Marketing and trading segment revenues were $667 million lower in the
six-month period ended June 30, 2002, compared to the same period in the prior
year as a result of:

     *    decreased revenues from generation sales other than native load due to
          lower market prices and resulting lower sales volumes ($128 million);
     *    decreased revenues from other realized marketing and trading in the
          current period primarily due to lower prices ($441 million);
     *    change in prior period mark-to-market gains on contracts delivered
          during the current period due to higher volumes being delivered ($37
          million decrease); and
     *    lower mark-to-market gains for future period deliveries primarily as a
          result of lower market liquidity and lower price volatility, resulting
          in lower volumes ($61 million).

     Marketing and trading segment purchased power and fuel costs were $521
million lower in the six-month period ended June 30, 2002, compared to the same
period in the prior year as a result of:

                                       7
<PAGE>
     *    decreased fuel costs related to generation sales other than native
          load primarily because of lower sales volumes and lower natural gas
          prices ($57 million);
     *    decreased purchased power costs related to other realized marketing
          and trading in the current period primarily due to lower prices ($472
          million); and
     *    change in prior period mark-to-market fuel costs for current period
          deliveries ($8 million net increase).

     The increase in real estate gross margin of $15 million was primarily due
to increased sales activities.

     The decrease in operations and maintenance expense of $11 million was
primarily due to lower costs related to generation reliability, plant outages
and maintenance costs. Operation and maintenance expense was also lower as a
result of the reversal of $4 million of a $10 million reserve recorded in the
prior period for the California energy situation. These decreases were partially
offset by increased employee benefit and other costs.

     The decrease in depreciation and amortization expense of $9 million
primarily related to lower regulatory asset amortization, in accordance with
APS' 1999 regulatory settlement, partially offset by increased depreciation on
higher plant balances.

     Net other income (expense) decreased $9 million primarily due to an
insurance recovery recorded in the prior period related to environmental
remediation costs and losses recorded on El Dorado's investments in the current
period, partially offset by lower miscellaneous non-operating costs.

     OPERATING RESULTS - TWELVE-MONTH PERIOD ENDED JUNE 30, 2002 COMPARED WITH
     TWELVE-MONTH PERIOD ENDED JUNE 30, 2001

     Our consolidated net income for the twelve months ended June 30, 2002 was
$315 million compared with $285 million for the same period in the prior year.
We recognized a $12 million after-tax loss in the twelve months ended June 30,
2002 and a $3 million after-tax loss in the twelve months ended June 30, 2001 as
cumulative effects of a change in accounting for derivatives, as required by
SFAS No.133.

     Our income before accounting change for the twelve months ended June 30,
2002 was $327 million compared with $288 million for the same period a year
earlier. The period-to-period comparison benefited from increased earnings
contributions from our regulated retail electricity and real estate operations
that were partially offset by lower earnings contributions from our marketing
and trading activities and higher operations and maintenance expenses. The
retail comparison was favorably impacted by lower replacement costs for power
plant outages, lower costs for purchased power and gas related to lower market
prices, customer growth and higher average usage per customer, partially offset
by the effects of milder weather and a retail electricity price decrease. The
real estate results benefited primarily from more sales activities. The
comparison for marketing and trading activities reflects lower volumes and

----------
(a)  Net marketing and trading gains (excluding the effects of generation sales
     other than native load) recognized for the current period decreased $16
     million.

(b)  Essentially all of our marketing and trading activities are structured
     activities. This means our portfolio of forward sales positions is
     economically hedged with a portfolio of forward purchases that protects the
     economic value of the sales transactions.

ELECTRIC RETAIL SEGMENT GROSS MARGIN

     Revenues related to our regulated retail and wholesale electricity
businesses were $477 million lower in the twelve-month period ended June 30,
2002, compared to the same period in the prior year as a result of:

     *    decreased revenues related to traditional wholesale sales as a result
          of lower sales volumes and lower prices ($177 million);
     *    decreased revenues related to wholesale sales, as a result of lower
          sales volumes and lower prices ($301 million);
     *    decreased retail revenues related to milder weather ($14 million);
     *    increased retail revenues related to customer growth and higher
          average usage, excluding weather effects ($44 million);
     *    decreased retail revenues related to a reduction in retail electricity
          prices ($28 million); and
     *    other miscellaneous factors ($1 million net decrease).

     Electric retail segment purchased power and fuel costs were $625 million
lower in the twelve-month period ended June 30, 2002, compared to the same
period in the prior year as a result of:

     *    decreased costs related to traditional wholesale sales as a result of
          lower sales volumes and lower prices ($177 million);
     *    decreased costs related to lower prices for hedged natural gas and
          purchased power prices ($331 million);
     *    decreased costs related to the effects of milder weather on retail
          sales ($5 million);
     *    increased costs related to retail sales growth, excluding weather
          effects ($17 million);
     *    decreased replacement power costs for power plant outages due to lower
          market prices and fewer unplanned outages ($126 million); and
     *    miscellaneous factors ($3 million net decrease).

MARKETING AND TRADING SEGMENT GROSS MARGIN

     Marketing and trading segment revenues were $616 million lower in the
twelve-month period ended June 30, 2002, compared to the same period in the
prior year as a result of:

     *    decreased revenues from generation sales other than native load due to
          lower market prices and resulting lower sales volumes ($212 million);
     *    decreased revenues from other realized marketing and trading in the
          current period primarily due to lower prices ($359 million);
     *    change in prior period mark-to-market gains on contracts delivered
          during the current period due to higher volumes being delivered ($80
          million decrease); and
     *    higher mark-to-market gains for future period deliveries primarily as
          a result of greater market liquidity and greater price volatility,
          resulting in higher volumes ($35 million).

     Marketing and trading segment purchased power and fuel costs were $524
million lower in the twelve-month period ended June 30, 2002, compared to the
same period in the prior year as a result of:

     *    decreased fuel costs related to generation sales other than native
          load primarily because of lower sales volumes and lower natural gas
          prices ($100 million);
     *    decreased purchased power costs related to other realized marketing
          and trading in the current period primarily due to lower prices ($431
          million);
     *    change in prior period mark-to-market fuel costs for current period
          deliveries related to accounting for derivatives ($8 million
          increase); and
     *    other miscellaneous factors ($1 million decrease).

     The increase in real estate gross margin of $16 million was primarily due
to increased sales activities.

     The increase in operations and maintenance expense of $29 million was
primarily due to higher costs related to generation reliability, plant outages
and maintenance costs. Operations and maintenance expense was also higher due to
increased employee benefit and other costs. These factors were partially offset
as a result of the reversal of $4 million of a $10 million reserve recorded in
the prior period for the California energy situation.

     The decrease in depreciation and amortization expenses of $12 million
primarily related to lower regulatory asset amortization, in accordance with
APS' 1999 regulatory settlement, partially offset by increased depreciation on
higher plant balances.

     Net other income (expense) improved $11 million primarily due to lower
losses recorded on El Dorado's investments in the current period than in the
prior period. These reductions were partially offset by the effects of an
insurance recovery recorded in the prior period related to environmental
remediation costs.

     Net interest expense decreased $7 million primarily because of the increase
in capitalized interest on our generation expansion program and the effects of
lower interest rates. These reductions in net interest expense more than offset
the increase in interest expense on higher debt balances primarily related to
our generation expansion program.

Prior Period Mark-To-Market (Gains)     The reversal of the gross margin related
Losses on Contracts Delivered During    to mark-to-market transactions entered
Current Period                          into in prior periods for which the
                                        commodities were delivered in the
                                        current period. Realization of
                                        prior-period mark-to-market relates to
                                        cash flow recognition, not revenue
                                        recognition or earnings recognition,
                                        because in accordance with
                                        mark-to-market accounting, the margin
                                        was already recorded in the prior
                                        period. A negative amount shown in this
                                        category represents the arithmetic
                                        opposite of a gain recognized in the
                                        period in which the commodities were
                                        delivered; an equal positive amount is
                                        reflected in the realized revenue or
                                        margin for delivered commodities. A
                                        positive amount shown in this category
                                        represents the arithmetic opposite of a
                                        loss recognized in the period in which
                                        the commodities were delivered; an equal
                                        negative amount is reflected in the
                                        realized revenue or margin for delivered
                                        commodities.
