AVISTA UTILITIES FILES APPLICATION SEEKING APPROVAL TO IMPLEMENT
RESIDENTIAL AND SMALL FARM ENERGY RATES
Avista Utilities has filed an application with the Idaho Public Utilities Commission seeking approval to implement
residential and small farm energy rates for electric service.
The utility, which serves customers in northern Idaho, said the electric residential and farm energy rate adjustment
results from an agreement between it and the Bonneville Power Administration. The agreement provides a share of
the benefits of the federal Columbia River power system to residential and small farm customers of the six investor-
owned utilities in the Pacific Northwest.
Avista is proposing a residential and small farm energy rate adjustment credit rate for rate schedules 1, 12, 22, 32
and 48 of 0.366 cents per kilowatt-hour. This represents a $0.2 million, or 0.1 percent increase to qualifying
customers. Residential customers using an average of 927 kilowatt-hours per month would see their monthly bills
increase from $85.40 to $85.53, or 0.2 percent.
Written comments on the application are being accepted until Sept. 13, 2023. Comments must be filed through the
Commission’s website or by e-mail unless computer access is not available. To comment through the Commission’s
website, please visit puc.idaho.gov and click on the “Case Comment Form” link on the upper left side of the page.
Please use case number AVU-E-23-11 when filling out the form. If submitting comments using e-mail, please send them
to the Commission secretary and Avista at the e-mail addresses listed below.
AVISTA UTILITIES FILES ANNUAL POWER COST ADJUSTMENT APPLICATION
Written comments are being accepted on an Avista Utilities application seeking approval of its annual power cost
adjustment.
If approved by the Idaho Public Utilities Commission, the average residential electric customer’s monthly bill would
increase by $3.23, or 3.8 percent.
The utility’s power cost adjustment tracks revenue and cost changes associated with variations in hydroelectric
generation, secondary prices, thermal fuel costs and changes in power contract revenues and expenses.
The Commission is accepting written comments until Sept. 12, 2023. Comments are required to be filed through the
Commission’s website or by e-mail unless computer access is not available. To comment electronically, please visit the
Commission website at puc.idaho.gov and click on the “Case Comment Form” link on the upper left side of the page.

Please complete the form using case number AVU-E-23-08. If filing by e-mail, comments are required to be sent to
the Commission secretary and Avista at the e-mail addresses listed below.
AVISTA UTILITIES FILES APPLICATION TO ADJUST FIXED COST ADJUSTMENT RATES
FOR NATURAL GAS SERVICE
Avista Utilities has filed an application with the Idaho Public Utilities Commission seeking approval to adjust the fixed
cost adjustment rates for natural gas service from Nov. 1, 2023, through Oct. 31, 2024.
If approved by the Commission, natural gas residential customers will see a rebate of 1.219 cents per therm, or a 0.2
decrease. Natural gas non-residential customers would see a rebate of 0.632 cents per therm, or a 1.2 decrease. The
application is a proposal and subject to Commission review and approval.
The fixed cost adjustment is a rate adjustment mechanism designed to address the link between the energy a utility
sells and the revenue it collects to recover fixed costs of providing service, which decouples the utility’s revenues from
its customers’ energy usage. The decoupling aims to remove a utility’s incentive to increase sales to increase revenue
and profits and encourages energy conservation.
The Commission is accepting written comments until Oct. 4, 2023. Comments are required to be filed through the
Commission’s website or by e-mail unless computer access is not available. To comment electronically, please visit the
Commission website at puc.idaho.gov and click on the “Case Comment Form” link on the upper left side of the page.
When filling out the form, please use case number AVU-G-23-05.
COMMISSION APPROVES NORTHERN IDAHO UTILITY’S APPLICATIONS THAT WILL
CHANGE CUSTOMER RATES
The Idaho Public Utilities Commission has approved four applications from Avista Utilities that will increase customer
monthly rates by an average of $1.14 beginning Oct. 1.
Avista’s applications asked for approval to decrease its Schedule 91 – Energy Efficiency Rider Adjustment rates,
approval to change the Power Cost Adjustment surcharge rate, approval of deferrals from July 1, 2022 through June
30, 2023 and for authorization to adjust its Fixed Cost Adjustment rates for electric service as well as approval to
implement changes to residential and small farm credit rates for electric service.
Schedule 91 is designed to recover costs associated with energy efficiency services and programs offered to
customers. It also provides customers with financial incentives or rebates for participating in electric energy efficiency
programs offered by Avista. The Commission approved Avista’s request, which will decrease the average residential
customer’s bill by approximately 97 cents per month relative to Schedule 91.
The utility’s Power Cost Adjustment is an annual adjustment mechanism that monitors changes in hydroelectric
generation, secondary prices, thermal fuel costs and other changes in power contract revenues and expenses. Avista
said residential customers using an average of 927 kilowatt-hours per month would see monthly bills increase from
$85.40 to $88.63.
The Fixed Cost Adjustment is a rate adjustment mechanism that is designed to break the link between the energy a
utility sells and the revenue it collects to recover the fixed costs of providing service. This decouples the utility’s
revenues from its customers’ energy usage. Avista said residential customers would see a change in their rebate rate
from $0.405 cents to a rate of $0.540 cents per kilowatt-hour and non-residential customers would see a rebate rate
change from $0.034 cents to $0.048 cents per kilowatt-hour.
The credit rates are provided to residential and small farm customers as part of an agreement between Avista and
the Bonneville Power Administration. The agreement provides a share of the benefits of the federal Columbia River

power system to these customers. Avista said residential customers using an average of 927 kilowatt-hours per month
would see monthly bills increase from $85.40 to $85.53.
COMMISSION APPROVES NATURAL GAS UTILITY’S APPLICATIONS THAT WILL
CHANGE CUSTOMER RATES
The Idaho Public Utilities Commission has approved two applications submitted by Avista Utilities that will change the
rates customers pay for natural gas.
Avista asked the Commission for approval to adjust the fixed cost adjustment (FCA) rates and approval to change
purchased gas cost adjustment (PGA) rates. The FCA is a rate
adjustment mechanism that is designed to separate the link between the energy a utility sells and the revenue it
collects to recover fixed costs of providing service, which decouples
Avista’s revenues from customers’ energy usage. The decoupling removes a utility’s incentive to increase sales to
increase revenue and profits and encourages energy conservation.
The approval of the FCA application will reduce residential customers’ rates by 0.2 percent. This represents a rebate
of 1.219 cents per therm. Non-residential customers will see a decrease of 1.2 percent, which represents a rebate of
0.632 cents per therm.
The PGA is a Commission-approved mechanism that adjusts rates up or down to reflect changes in Avista’s costs to
buy natural gas from suppliers. These include changes in transportation, storage and other related costs. The approval
of the PGA will increase residential customers’ rates by $3.54, or 4.7 percent per month. Other groups of customers
also will see an increase in rates.

Idaho Power Company
COMMISSION SCHEDULES ONLINE PUBLIC WORKSHOPS ON TRANSMISSION LINE
PROJECT
The Idaho Public Utilities Commission will host public workshops on April 17 and April 19 to share information on
applications from two electric utilities that have applied for permits to build a 500-kilovolt transmission line.
Rocky Mountain Power and Idaho Power have applied for certificates of public convenience and necessity as part of
the process to build the Boardman-to-Hemingway transmission line, which they will co-own. A certificate of public
convenience and necessity is a permit granted to a utility that allows it to provide service to a new geographic area,
enter into a franchise agreement, build and operate a new facility or build an extension of an existing facility. The
permit covers activities that are outside of a utility’s usual course of business.
Rocky Mountain Power said the transmission line is needed to create lower-cost and more reliable electricity
transmission service for its growing customer load and to avoid spending more for higher-cost generation and
transmission resources.
Idaho Power said population and business growth in the region are increasing demand for electricity, and existing
transmission lines can’t carry additional electricity when it is most needed.
The workshop for Idaho Power’s application will be Monday, April 17. Staff with the public utilities Commission will
present information on the application and answer questions. It will start at 6:00 p.m. (MDT) and end at 9:00 p.m., or
after questions from the public have been answered, whichever comes first. To participate over the phone, please call

1-415-655-0001 and enter meeting number 2454 319 4150 when prompted. Next, enter this numeric password:

COMMISSION SCHEDULES PUBLIC HEARING ON PROPOSED TRANSFER OF LAND
FROM IDAHO POWER TO PARKS AND RECREATION
The Idaho Public Utilities Commission is hosting a telephonic public hearing on May 11 to take formal testimony on an
Idaho Power application to transfer land on Ritter Island to the Idaho Department of Parks and Recreation.
The application asks for approval from the Commission to transfer 1.09 acres of land on the island, which is located
along the Snake River and is part of the Thousand Springs State Park. The proposed asset transfer is part of
negotiations that ultimately led to the relicensing of Idaho Power Company’s mid-Snake hydro facilities. This proposal
arose, in part, due to the understanding that the asset transfer would assist with aquatic habitat mitigation
requirements.
Those interested in submitting testimony for the record are asked to call 1-415-655-0001, and enter meeting number
2451 727 1983 when prompted shortly before 11:00 a.m. (MDT) on Thursday, May 11. Testimony also can be
submitted in person at the Commission, 11331 W. Chinden Boulevard, Building 8, Suite 201-A.
The Commission is accepting written comments on the proposed transfer until May 3, 2023. Comments are required to
be filed through the Commission’s website
or by e-mail unless computer access is not available. To comment electronically, please visit the Commission’s
webpage at puc.idaho.gov. Please click on the

“Case Comment Form” link on the upper left side of the page and use case number IPC-E-23-07 when filling out the
form.
If submitting comments using e-mail, comments are required to be sent to the Commission and Idaho Power at the e-
mail addresses listed below.
COMMISSION APPROVES ENERGY SERVICES AGREEMENT BETWEEN IDAHO
POWER AND BRISBIE
On May 11, 2023, the Idaho Public Utilities Commission approved an energy services agreement that allows Idaho
Power to provide electric service to a new data center in the Kuna, Idaho area.
The data center, owned by Brisbie, LLC, will be a large power service customer of Idaho Power. Large power service
customers are those who use between 10,000 kilowatts and 20,000 kilowatts of power. Customers that receive in
excess of 20,000 kilowatts are required to make special contract arrangements with Idaho Power.
Before the energy services agreement was approved, staff with the Idaho Public Utilities Commission reviewed it and
additional supporting materials that were filed by Idaho Power to ensure existing Idaho Power customers would not
see their rates increase as a result of the energy service agreement, among other items. An evaluation of the energy
services agreement was intended to address concerns about Brisbie being Idaho Power’s largest customer with a
significant impact to Idaho Power’s system and cost structure, which had the potential to increase the risk to other
utility customers. In addition, how the rates Idaho Power will charge were determined may be used as a model for this
type of customer in the future, which could increase the risk to other customers.
Idaho Power is planning to obtain enough renewable resources to meet Brisbie’s initial annual energy requirements in
the short-term through a power purchase agreement and will build or obtain additional resources to meet the data
center’s energy requirements going forward.
Brisbie plans to support 100 percent of its operations through the addition of renewable resources, which would be
connected to Idaho Power’s system.
CUSTOMER HEARINGS SCHEDULED IN JUNE ON APPLICATIONS THAT WOULD
ADVANCE TRANSMISSION LINE PROJECT
The Idaho Public Utilities Commission will host customers hearings in mid-June to take testimony on applications that

Idaho Power and Rocky Mountain Power have partnered to work on the Boardman to Hemingway transmission line.
Plans call for the line to be 300 miles long. It will cross five Oregon counties and connect to Idaho Power’s existing
Hemingway Substation in Idaho’s Owyhee County.
The two utilities have applied for certificates of public convenience and necessity as part of the project. A certificate
of public convenience and necessity is a certificate granted to a utility that allows it to provide service to a new
geographic area, enter into a franchise agreement, build and operate a new facility or build an extension of an
existing facility.
Four customer hearings will be held to take testimony for the record. Those who plan to submit testimony are required

COMMISSION APPROVES IDAHO POWER APPLICATIONS THAT WILL CHANGE
RATES
The Idaho Public Utilities Commission has approved two Idaho Power applications that will change customer rates.
The utility received approval for its power cost adjustment (PCA) rates and fixed cost adjustment (FCA) rates.
The PCA allows Idaho Power to increase or decrease the PCA rates to reflect the utility’s annual costs of supplying
power. Because of a diverse generation portfolio, Idaho Power’s actual costs of providing electricity varies annually
depending on factors such as river streamflow, the amount of purchased power, fuel costs, and the market price of
power, among other factors. The annual PCA is combined with Idaho Power’s base rates to create a customer’s overall
energy rate. The PCA can only be used to pay power supply expenses. Neither Idaho Power or its shareholders
receive a financial return from the PCA.
To assist customers, this year’s PCA will be spread equally over two years to mitigate impacts on customers. For the
average residential customer using 950 kilowatt-hours per month, the expected increase is approximately $12.72
per month.
The FCA annually adjusts rates up or down to recover the difference between the fixed costs authorized by the
Commission and the actual fixed costs Idaho Power recovers from customers for the sale of electricity during the
previous year. Fixed costs are a utility’s costs to provide service that do not vary with fluctuations in energy
consumption. Variable costs change based on the energy generated and consumed. The FCA applies to residential
and small commercial customers.
A typical residential customer using 950 kilowatt-hours per month will see an approximate $1.66 decrease in their
monthly bill from June 1, 2023, through May 31, 2024. This represents a 1.56 percent decrease. This decrease also
will apply to small general service customers for the same timeframe.

Accounting for the PCA and FCA, residential customers will see an increase of 10.34 percent, small general service
customers will see an increase of 8.08 percent, large general service customers will see an increase of 16.19 percent,
large power customers will see an increase of 20.26 percent and irrigation customers will see an increase of 15.01
percent. A typical residential customer will see an overall monthly increase of $11.06 between the two filings.

IDAHO POWER APPLICATION TO EXPAND OPTIONAL CLEAN ENERGY OFFERINGS
APPROVED BY COMMISSION
The Idaho Public Utilities Commission has approved an application from Idaho Power that will allow the utility to
expand optional clean energy offerings to customers.
The approval will allow Idaho Power to rename the existing Schedule 62 – Green Power Purchase Program Rider to
Clean Energy Your Way. In addition, Idaho Power will be allowed to maintain and expand procurement options for
the renewable energy certificate offering under the name Clean Energy Your Way – Flexible, establish a regulatory
framework for a future voluntary subscription green power service offering named Clean Energy Your Way –
Subscription and offer a tailored renewables option to the utility’s largest customers called Clean Energy Your Way –
Construction.
Idaho Power said the Clean Energy Your Way – Flexible option would operate similarly to its existing Green Power
Program. The utility asked for approval to expand renewable energy certificate purchase options to keep up with
demand and satisfy customers with near-term clean energy goals that can be met with renewable energy certificates.
Idaho Power proposed two options for customers regarding renewable energy certificates, the limited bulk purchase
option and the renewable energy certificate “sleeve” option.
Under the limited bulk purchase option, the utility would buy a limited number of renewable energy certificates (not to
exceed $5,000 at any time); and sell them to interested customers later under customer-specific sale agreements. The
“sleeve” option will allow Idaho Power to connect customers to non-company renewable energy certificate purchases.
Idaho Power said this option would work similarly to the limited bulk purchase option, where the utility would sell
procured renewable energy certificates to interested customers at cost. This option would not create proceeds that
would pass through the utility’s power cost adjustment.
The Clean Energy Your Way – Subscription option will allow customers to subscribe to a portion of the output from a
new renewable resource on the utility’s system. This option would be open to any customer. However, Idaho Power
proposed an individual customer cap of 15 percent of program activity. The proposed individual subscription size
would be based on a customer’s average prior year energy usage.  
The Clean Energy Your Way – Construction option offers large customers a tailored approach to cover 100 percent
of their energy use with a new renewable resource. A customer’s energy usage is reconciled against the generation of
a renewable resource, or resources, on an hourly basis.

Rocky Mountain Power
COMMISSION SCHEDULES PUBLIC WORKSHOP, HEARING ON ROCKY MOUNTAIN
POWER APPLICATION TO CHANGE RATES.
Idaho Public Utilities Commission staff will host a public and customer workshop as well as a public hearing regarding
an application from Rocky Mountain Power to change its rates.
The utility, which serves approximately 86,500 customers in eastern Idaho, is asking for Commission approval to
gradually transition, over five years, an increase to the customer service charge for two residential rate schedules to
$29.25 per month and at the same time reduce energy charges proportionately. This change is proposed for Electric
Service Schedule No. 1 – residential service, and Electric Service Schedule No. 36 – optional time-of-day residential
service.
The utility also proposes to eliminate inclining block tiered rates for Schedule 1, so that the current first- and second-
tier energy charge rates would be the same within a season. The application also asks for approval to change the
time of use periods in Schedule 36, so the definitions of on- and off-peak periods match those listed on Electric
Service Schedule 9 (general service – high voltage).

Staff with the Commission will host a customer and public workshop to share information regarding the application on
Tuesday, March 14, at the Idaho Department of Fish and Game regional office in Idaho Falls, 4279 Commerce Cir.
The workshop will start at 6:00 p.m. (MDT). Customers and the public can attend in-person or online. To listen to the

COMMISSION SCHEDULES ONLINE PUBLIC WORKSHOPS ON TRANSMISSION LINE
PROJECT
The Idaho Public Utilities Commission will host public workshops on April 17 and April 19 to share information on
applications from two electric utilities that have applied for permits to build a 500-kilovolt transmission line.
Rocky Mountain Power and Idaho Power have applied for certificates of public convenience and necessity as part of
the process to build the Boardman-to-Hemingway transmission line, which they will co-own. A certificate of public
convenience and necessity is a permit granted to a utility that allows it to provide service to a new geographic area,
enter into a franchise agreement, build and operate a new facility or build an extension of an existing facility. The
permit covers activities that are outside of a utility’s usual course of business.
Rocky Mountain Power said the transmission line is needed to create lower-cost and more reliable electricity
transmission service for its growing customer load and to avoid spending more for higher-cost generation and
transmission resources.
Idaho Power said population and business growth in the region are increasing demand for electricity, and existing
transmission lines can’t carry additional electricity when it is most needed.
The workshop for Idaho Power’s application will be Monday, April 17. Staff with the public utilities Commission will
present information on the application and answer questions. It will start at 6:00 p.m. (MDT) and end at 9:00 p.m., or
after questions from the public have been answered, whichever comes first. To participate over the phone, please call

COMMISSION APPROVES TWO APPLICATIONS THAT WILL CHANGE RATES FOR
EASTERN IDAHO ELECTRIC UTILITY CUSTOMERS
The Idaho Public Utilities Commission has approved two applications submitted by Rocky Mountain Power that will
change the rates the utility charges customers for electricity service. Rocky Mountain Power asked for approval to
adjust rates under the Energy Cost Adjustment Mechanism (ECAM). The utility also asked for approval to implement a
residential rate modernization plan.
The ECAM allows Rocky Mountain Power to increase or decrease rates each year to reflect changes in power supply
costs. These costs vary year by year based on the utility’s costs relating to gas, coal, surplus power sales, power
purchases, and transmission costs. Rates for customers will increase from 1.6 percent to 3.0 percent depending on the
category a customer is in. The monthly average bill for a residential customer using 783 kilowatt hours will increase
by approximately $1.57. Rocky Mountain Power will be allowed to recover $32.5 million because of the approved
changes.
In addition to the ECAM, the Commission approved a rate modernization plan that will be fully implemented over a
five-year period. Rocky Mountain Power bills residential customers monthly. Customers pay a fixed service charge as
well as an energy charge based on the amount of electricity used. The utility said the current $8.00 per month
customer service charge does not cover the fixed costs incurred by residential customers. Because of that, the recovery
of fixed costs have been shifted to the volumetric energy charges.
Rocky Mountain Power asked for, and received, approval to increase the customer service charge for certain classes
of customers from $8.00 per month to $29.25 per month over the course of five years. The volumetric energy charges
will be lowered as the raises to the service charge are implemented.
TELEPHONIC PUBLIC HEARING SCHEDULED TO TAKE TESTIMONY ON PROPOSED
ASSET TRANSFER AGREEMENT
The Idaho Public Utilities Commission will host a telephonic public hearing on July 10 to take testimony on a proposed
agreement that would transfer assets from Rocky Mountain Power to the city of Idaho Falls.

In an application submitted to the Commission, Rocky Mountain Power proposes to transfer assets located on or near
Pioneer Road in Idaho Falls to the city. The application also outlines the city’s compensation for the assets and
compensation for the transfer of a Rocky Mountain Power customer to the city.
The telephonic hearing is Monday, July 10, at 11:00 a.m. to take testimony from the public and Rocky Mountain
Power customers. Those interested in submitting testimony can call 1-415-655-0001, and enter meeting number 2632
070 9027 when prompted. Next, please enter this numeric password: 282 48 429. Those planning to testify are
encouraged to start calling in at 10:45 a.m. on July 10.
COMMISSION APPROVES EASTERN IDAHO UTILITY’S APPLICATION TO DECREASE
RESIDENTIAL AND SMALL FARM CREDIT
The Idaho Public Utilities Commission has approved an application from Rocky Mountain Power to decrease the
residential and small farm credit provided by the Bonneville Power Administration.
The Northwest Power Act of 1980 created the Residential Exchange Program that is administered by the Bonneville
Power Administration. The program allows participating utilities to
pass the benefits of the federal Columbia River power system to eligible residential, small farm and irrigation
customers through rate credits. Rocky Mountain Power asked the Commission to
approve a Schedule 34 Residential Exchange Program credit of $0.007376 per kilowatt-hour for rate schedules 1,
6A, 7A, 10, 23A, 35A and 36. The utility asked that the new rate be effective from
Oct. 1, 2023, through Sept. 30, 2025.
The previous rate credit was $0.010133 per kilowatt-hour. The change in the credit rate will increase the monthly
power bill of a typical residential customer by $2.27.
COMMISSION ACKNOWLEDGES EASTERN IDAHO ELECTRIC UTILITY’S INTEGRATED
RESOURCE PLAN
The Idaho Public Utilities Commission has acknowledged Rocky Mountain Power’s 2023 Integrated Resource Plan (IRP)
to meet future energy and demand requirements for its customers.
The utility’s IRP is filed with the Commission on a biennial basis. Rocky Mountain Power said the plan fulfills its
commitment to develop a long-term resource plan that considers cost, risk, uncertainty and the public interest. The
utility said the 2023 IRP preferred portfolio includes new resources from the 2020 all-Source Request for Proposals
(RFP) including 1,792 megawatts (“MW”) of wind and 495 MW of solar additions with 200 MW of battery storage
capacity. The utility said these are scheduled to come online between 2024 and 2025.
Rocky Mountain Power’s plan also calls for acquiring and repowering the Rock River I and Foote Creek II-IV wind
projects in Wyoming. The utility also said the 2023 IRP preferred portfolio includes the 500 megawatt advanced
nuclear Natrium demonstration project, which is anticipated to go online by the summer of 2030, 1,000 megawatts of
additional advanced nuclear resources through 2033 and 1,240 megawatts of non-emitting peaking resources
through 2037.
The preferred portfolio also includes construction of the Gateway South 416-mile 500-kilovolt transmission line that
will connect southeastern Wyoming and northern Utah, the Gateway West Segment D.1 59-mile 230 kilovolt
transmission line in eastern Wyoming and the Boardman to Hemingway 500 kilovolt, 290-mile transmission line across
eastern Oregon and southwestern Idaho.

The Commission’s acknowledgement of the integrated resource plan reflects that it is a working document that
incorporates assumptions and projections at a specific point in time. The Commission acknowledges Rocky Mountain
Power’s ongoing planning process, not the conclusions or results reached through that process.

General
CITING CONCERNS, COMMISSION DECLINES PARTICIPATION IN INITIATIVE TO
CREATE WESTERN-BASED ENERGY MANAGEMENT GROUP
The Idaho Public Utilities Commission issued the following response regarding an invitation to participate in the West-
Wide Governance Pathway Initiative:
Having considered the representations, actions, and current goals of the West-Wide Governance Pathway Initiative,
the Idaho Public Utilities Commission unanimously chooses not to participate with the Initiative.
The IPUC’s concerns include, among other things, that: (1) the Initiative has been less than transparent concerning its
creating and funding; (2) there is no evidence that the Initiative’s goal of independent governance is feasible without
changes in California’s legislation; (3) the Initiative’s timeline of seating a board by January 2024 is premature and
unrealistic; and (4) at its core, the Initiative presumes economic benefits for western states without justification or
specifics.
“As always, the IPUC respects other Commission, State and Stakeholders’ decisions concerning participation with the
Initiative,” Commission President Eric Anderson said. “However, given the IPUC’s concerns, the inherent flaws in the
creation of the Initiative, and the Initiative’s current actions and goals, the IPUC does not see a viable path forward
for the Initiative or that participation would result in any specific net economic benefits for Idaho customers.”
