- Property Data
- Comp Set Data
- Industry Data
- Corporate Data
- International Issues
- Additional Data
3Property Data
4Starts with Raw Data
- ___Raw sales data_____for every hotel is obtained
from clients via corporate feeds or web entry - Sample monthly file
- Daily file would look the same except for the
date field, YYYYMMDD or 20100725
5STR Data Guidelines
- Supply (___Room available__) the number of
rooms in a hotel multiplied by the days in the
month - Demand (_room sold____) number of rooms sold by
a hotel, does not include comp rooms or
no-shows - Revenue total room revenue generated from the
__sale of room___, includes __________not resort
fees, nothing else such as _______
6Key Performance Indicators
- From these raw data values, STR calculates the
three __key performance indicators_____(KPIs),
which are used for reports - ___occupancy____-
- ___average daily rate____-
- __revenue per available room____-
important metric, based upon all rooms, some
feel like it is better measurement of
profitability
7Occupancy
Definition The percentage of available rooms that
were sold during a specific time
period. Calculation Occupancy is calculated by
dividing the demand (__number of rooms sold___)
by the supply (__number room of available___),
this is a percentage Occupancy Demand / Supply

You could multiply times 100 or format as a
percentage
9ADR
Definition A measure of ____the average rate
paid___for rooms sold during a specific time
period. Calculation ADR is calculated by
dividing _the room revenue__by the demand
(__rooms sold__), this is a dollar amount ADR
Revenue / Demand

You could format as a or as a number with 2
decimals
11RevPAR
Definition A measure of the revenue that is
generated by a property in terms of ___each room
available__. This differs from ADR because RevPAR
is affected by the amount of unoccupied rooms,
while ADR only shows the average rate of rooms
actually sold. Calculation RevPAR is calculated
by dividing the _room__by the ____total number of
rooms available____. RevPAR Revenue / Supply

13Percent Changes
- Definition
- The comparison of __This year__(TY) numbers vs.
_Last year__(LY) numbers. The percent change
illustrates the amount of growth (__up, flat,
down__) from the same period last year. - Calculation
- Percent Change ((This Year Last Year) / Last
Year) 100

16Daily vs. Monthly Data
- Formulas for KPIs and Percent Changes are the
same - The date fields are different
- 201007 monthly
- 20100725 daily
- Most daily percent changes are based upon
________, in other words _________________________
____ - Thu 20100715 compared to Thu 20090716
- Sat 20100731 compared to Sat 20090801
17Multiple Time Periods
- Multiple time periods for monthly data include
- Year-to-Date (YTD)
- Running 12-Month (_12-moth moving Avg___)
- Running 3-Month
- Multiple time periods for daily data include
- Current Week
- Month-to-Date (YTD)

20Other Multiple Time Periods
- The Raw data for other monthly and daily time
periods are calculated the same way by
aggregating the raw data for every month or day
in the entire time period - The calculated metrics (Occupancy, ADR, and
RevPAR) for multiple time periods are always
calculated from ___________________ - Numbers for multiple time periods never use
averages of monthly values
21Percent Changes for Multiple Time Periods
- The percent changes for multiple time periods are
based on the aggregated values or the calculated
metrics which are derived from the aggregated
values for this year compared to the same values
for last year - Percent changes for daily data are based upon
groups of comparable days, with the exception of
Month-to-Date numbers which are based on a
date-to-date comparison

23Full Availability Subject Hotel
- Occasionally a subject hotel may report a Supply
number that is different than the number of rooms
in the property times the days in the period - If this happens in the case of the subject hotel,
their STAR report will always reflect the Supply
and the corresponding Occupancy based upon the
number _________________. - STR does not change the Supply number of the
subject hotel on their own STAR report

25Weekday/Weekend and Day of Week Data vs. Monthly
Data
- Sometimes a hotel will submit daily data that
does not add up exactly to the monthly number - There are good reasons for this some systems do
not accept adjustments to daily data, only to the
month numbers - STR will slightly adjust the daily numbers based
upon the monthly data when they are aggregated by
day of week and weekday/weekend
Use percentages for each day, ensures WD/WE adds
up
26Percent Changes and WD/WE or Day of Week Data
- ____________ (WD/WE) Percent Changes compare all
the aggregated weekday or weekend data (per month
or other time period) this year to the same data
last year - ____________(DOW) Percent Changes compare all the
aggregated daily data for a single day (per month
or other time period) this year to the same data
last year
27Running 4 Week Data
- The Weekly Reports compare individual daily data
for the Current Week to the Running 4 Week
numbers - The Running 4 Week numbers are the aggregated
data __________________, i.e. _____________ - A hotel can compare their Monday performance
metrics to the average of the last 4 Mondays
28Competitive Set Data
29Key Performance Indicators for the Competitive
Set
- Numbers for the comp set are derived based on
aggregated raw data - Supply, Demand, and Revenue numbers are the
combined values of each hotel in the comp set - Occupancy, ADR, and RevPAR numbers are bases on
the aggregated Supply, Demand, and Revenue
30Including or Excluding the Subject Hotel in the
Competitive Set
- STR allows companies to choose whether to include
or exclude the data for the subject hotel in the
numbers for the comp set - Historically companies usually included the data
for the subject hotel, but more recently most
companies have decide to exclude the subject - People feel that having the subject data included
in the comp set numbers distorts the comp set

35Index Numbers
- The Index numbers compare the performance of the
subject property to the comp set - Subject / Comp Set 100
- A number greater than 100 means the subject
property ____________ the comp set and a number
below 100 means the comp set ______________the
subject property - Index numbers are available for Occupancy, ADR,
RevPAR and the Percent Changes
Index numbers are percentages, multiple 100 or

39Ranking Data What is it?
- STAR Property Reports include Ranking information
for Occupancy, ADR, RevPAR and each Percent
Change, comparing the subject hotel to the comp
set - The Ranking data would be in the format of X of
Y, where X is the subject hotels position and Y
is the number of participating properties in the
comp set, for example 2 of 7 would mean the
subject hotel had _________________________
Ranking data gives you more than just the KPIs
Indexes
40Occupancy Ranking Data How?
- The values for each hotel in the comp set
including the subject hotel are sorted and then
the position of the subject hotel is determined
within the group
STR 1234 2345 3456 4567 (Subject) 5678 6789
Value 87 85 83 82 78 75
Rank 1 of 6 2 of 6 3 of 6 4 of 6 5 of 6 6 of 6
Subject had the 4th highest occupancy in the comp
set of 6
41ADR Ranking Data Ties
- If two or more hotels are tied, i.e. they have
the same value, then each hotel would get the
same number
STR 1234 2345 3456 4567 (Subject) 5678 6789
Value 97 95 95 95 92 88
Rank 1 of 6 2 of 6 2 of 6 2 of 6 5 of 6 6 of 6
Subject had the 2nd highest ADR (with 2 others)
in comp set
42Multiple Time Periods and Comp Set Data
- Multiple time periods are handled the same way
for a comp set as they are handled for a subject
property - The Raw data for monthly and daily time periods
are always aggregated and then calculations are
applied to the aggregated data
43Sufficiency of Comp Set Data
- If a Comp Set has 3 or more participating hotels
(submitting actual data) then that comp set is
defined as Sufficient - The numbers for that comp set can then appear on
the STAR report - Multi-year numbers are considered to be
sufficient if greater than 50 of the months or
day included in the multi-year period are
sufficient
44Full Availability and Comp Sets
- Occasionally a hotel in the comp set may report a
Supply number that is different than the number
of rooms in the property times the days in the
period - In those cases, STR uses the Supply number based
upon full availability, not the number that the
hotel reports

Formulas are based upon Actual Supply, not
Reported
46Non-Reporting Hotels in the Comp Set
- There may be situations where one or more hotels
in a comp set does not report data for a month or
more - First, the Supply, Demand, and Revenue for the
participating properties is aggregated. This is
the Sample Supply, Demand, and Revenue. - Next, an Occupancy and ADR is calculated based on
the Sample data
47Non-Reporting Hotels in the Comp Set - continued
- Then the Supply is determined for all hotels in
the comp set, simply the number of rooms times
the days in the month. This is referred to as
the Census Supply. - This Supply number is multiplied times the Sample
Occupancy to derive the Census Demand - The Census Demand is multiplied times the Sample
ADR to derive the Census Revenue

49Industry Data
50Industry Data Basics
- STR uses a variety of segments to analyze
performance of the hotel industry - There are __________(market, tract) and ________
(scale, location) categorizations - STAR Reports and corporate data files will
frequently compare a subject hotel to nearby
industry segments - Publications and Destination Reports will also
display the performance of industry segments
51The Methodology for Industry Data versus Comp Set
Data
- The methodology used for arriving at industry
numbers is different than the one for arriving at
comp set numbers - Actual data is used for hotels that participate
and modeled data is used for hotels that do
not participate - The Actual and Modeled data is aggregated for all
hotels in each industry segment
52Modeling of Industry Data
- STR estimates the data of non-participating
hotels to help increase the accuracy of industry
data - Data for a non-participant is estimated based on
participating hotels that are closest to the
non-participant based on geography and price
level - No modeled data is ever used in the Comp Set
numbers
Possible to explain technical procedure used for
modeling
53Key Performance Indicators for Industry Segments
- The Actual and Modeled data is aggregated for all
hotels in each industry segment - Supply, Demand, and Revenue numbers are the
combined values of each hotel in the comp set - Occupancy, ADR, and RevPAR numbers are based on
the aggregated Supply, Demand, and Revenue

56Percent Change Numbers for the Industry Segment
- Percent Change numbers for the industry segment
are calculated exactly like the ones for the comp
set or the subject property - These numbers show increases or decreases in
performance this year versus last year
57Multiple Time Periods and Industry Data
- Multiple time periods are handled exactly the
same for an industry as for a comp set or a
subject property - The Raw data for monthly and daily time periods
are always aggregated and then calculations are
derived based upon the aggregated data
58Sufficiency of Industry Data
- If an Industry segment has 4 or more hotels that
submit actual data, then that segment is defined
as Sufficient - The numbers for that industry segment can then
appear on STAR reports and elsewhere - Multi-year numbers are considered to be
sufficient if greater than 50 of the months or
day included in the multi-year period are
sufficient
59Full Availability
- Occasionally a hotel in the industry segment may
report a Supply number that is different than the
number of rooms in the property times the days in
the period - In those cases, STR uses the Supply number based
upon full availability, not the number that the
hotel reports
60Corporate Data
61What do Companies Receive?
- Most corporate headquarters receive reports
listing each of their hotels and the various
performance metrics, referred to as Index
Reports. These may be subtotaled. - Some companies receive Summary Reports
aggregating data for their hotels based upon
various subtotal groups. - Many companies receive data files containing this
same type of data to use internally
62Who do Companies Compare Their Hotels to?
- Most commonly, companies compare their hotels to
the corresponding comp sets - Sometimes they compare their hotels to the
corresponding industry segment of the subject
property, such as a Market or Tract Scale - They may compare total Brand numbers to the
corresponding Scale total, or to a group of other
brands, referred to as a Corporate Comp Set
63Corporate Aggregations
- Hotels can be grouped based upon common fields
such as Brand, State, or Operation - Hotels can also be grouped based upon
user-defined variables, such as Sales Regions or
Hotel Types - Raw data can be aggregated using Standard
Weighting or Portfolio Weighting
64International Issues
65Industry Segments
- In the US and in North America, probably the most
popular industry segment to compare hotels to are
Market Scale or Tract Scale - The Scale category is totally related to chain
hotels - Outside North America, since there are much less
chain hotels, Class is used instead and the
poplar segments are Market Class and Tract Class
66Currencies and Exchange Rates
- Outside the US, most hotels want to see their
STAR reports in their local currency - STAR obtains daily and monthly exchange rates for
all currencies in the world (at least the
countries that have hotels) from Oanda - Daily data utilizes the daily exchange rate
- Monthly data utilizes the daily exchange rate for
the last day of the month - Multi-year data is aggregated in local currency
67Additional Data
68Additional Issues/Topics
- Segmentation Data (Group, Transient, Contract)
- Additional Revenue Data (FB, Other, Total)
- Data within a Trend Report
- Data within a Hotel Review or Destination Report
