NFL Replica
jerseys?

4. Situation
Licensed Apparel Business
Impact
Reebok received an NFL
exclusive license in 2000
Highly seasonal & very uncertain
demand for player jerseys
Teams are more predictable, but
correlated with success
Hot-market players and teams
emerge during season
High margins, fashion item
Demand driven by availability
Unsold jerseys can become
instantly obsolete – trades;
design changes
No direct competition for
product – 100% market share
Demand is concentrated over
five month period
If product is not quickly
available to meet demand the
opportunity is lost
Lost sales cost more than
inventory overstocks, but come
with a high risk of obsolescence

5. Nature of Consumer Demand
• Sales are highest at start of season, August – Sept.
• “Hot market” players and teams emerge over course of
season
• Increase at end of season for contending teams & stars:
Christmas, playoffs and Super Bowl
• Off season is slower, with demand spikes for big-name player
movements

Aug

April
Sept -
Dec
Retailers get discount to place pre-season
orders for delivery in May
Limited ordering by retailers to re-balance
stocks; some short LT orders to respond
to player movements
Retailers order to position stock in their
DC’s and stores in anticipation of season,
and expect 3 – 4 week delivery LT
Retailers order to replenish stocks, chase
the demand, and expect 1 – 2 week LT for
Hot Market items 6

10. Purchasing Cycle
Reebok places orders on CMs for
April delivery; primarily orders blanks
(~20% of annual buy)
Reebok places orders for dressed
jerseys based on retailers’ advance
orders & remaining inventory (~ 15 –
20%) Reebok orders dressed & blank
jerseys, based on forecasts and
inventory targets
Last purchase phase is most
challenging

12. Single-Season Planning Problem
• What volume and mix of jerseys to purchase during March to June?
• Planning framework:
• Given forecasts (and advanced orders) for team and players
• Decide inventory targets for dressed and blank jerseys for season
• Place orders guided by these targets
• Revise forecasts (say) each month based on current information;
update targets accordingly
• How should we set inventory targets?

14. Representative Numbers for Replica
Jersey
Suggested Retail Price ---- more than $50
Wholesale Price = $24.00
Blank Cost = $9.50
Cost to dress at CM = + $1.40
Cost to dress at Reebok = + $2.40
Salvage Value for unsold Dressed Jersey = $7
Holding Cost for unsold Blank Jersey = $1.04
Salvage Value for unsold Blank Jersey = $9.50 -
1.04 = $8.46

15. 2003 Forecast – As of March 1, 2003
CMs have minimum order quantities of 1728
What should inventory target be for dressed jerseys for
each player? And blank jerseys for team?

18. Conclusion
• Context – fashion items, seasonal, high uncertainty in
demand
• Newsvendor with Risk Pooling provides way to plan for and
exploit postponement options
• Results in higher profits, 95% service level, better mix of
end-of-year inventory.
• Results in much different inventory plan – greater use of
blanks and local finishing
• Project resulted in planning tool and new insights for
planning for Reebok, and a thesis! A second project focused
on forecasting 18
What are the characteristics of this business? Distinctive elements? How could Reebok lose its license?
This reflects sales at retailers
This is Reebok’s sales cycle – sales by Reebok to retailers.
Reebok warehouse in Indy
Contract manufacturers – Asia, but more and more are being moved to central America and Caribbean (Honduras, El Salvador, DR)
Many contract manufacturers – why?
Most sales through large sports retailers, and thru distributors.
Indy has capability to do screen printing – for NFL roughly 30000 jerseys per week. Case does not tell us enough about whether or not this is constraining….but does indicate there are options to outsource locally at 10% premium.
It’s more expensive to screen print in Indy than at CM
Reebok has postponement opportunity -- but it costs more to dress in Indy than at CM, and there can be capacity and/or QR considerations too.
Note ordering in July 2005 for 2006 season!
During season (Sept. – Nov.) Reebok can expedite jerseys from CMs – by pulling forward the supply; that is in 2005 season, they can pull forward jerseys that have been ordered for 2006 season. This is expensive (air freight, special handling ,etc.) so Reebok does not plan on this – but will do to avoid shortages and lost sales.
Focus discussion on March to June time window.
Framework – how we wish to frame the problem for purposes of building a model?
Given framework, how do we set inventory targets? Suggest using newsvendor model, as we have a single period problem, i.e., effectively a single purchase opportunity.
This is key to have students think about how they would plan and manage procurement and inventories – with lots of SKUs; multiple CMs with constraints on what they can do; time delays due to shipping; and forecast dynamics as season gets closer in time.
Simple approach – view as a single period planning problem; create inventory targets for each player and for each team; place orders to build pipeline of stock, with objective to build to these targets; revise targets as get better forecasts….
Representative but not actual numbers; the salvage numbers are for Reebok, not for the retailer. In general, quite difficult to develop estimates for these salvage values.
Salvage value of blank jersey is cost of a blank, net of cost to hold in inventory for a year. ($9.50 – 1.04 = 8.46) --- if I have leftover blanks, Reebok will use next season, assuming no changes in design; but Reebok will incur a holding cost for having the jersey in stock for about one year.
For dressed – it can reflect what a jersey could be sold at discount for and/or cost of jersey net of risk-adjusted holding cost (to capture chance of becoming obsolete). The $7 reflects an estimate of what a discounter would pay Reebok to take the leftover dressed jersey. Dressed have lower savage value – because of risk that player retires, gets traded, stinks, etc.
Note that at retailer – end of season mark down is about $35; and they can’t return to Reebok.
Note that these 6 players could be manufactured to stock, and have quantities that exceed minimum order quantity of 1738
These questions occur for each team – and each team has similar numbers, 5 – 6 players that have significant demand, and then all the others.
Developing such a forecast is most difficult – largely judgmental, with some history of past sales; estimates of standard deviations are best guesses of the forecast error, again based on past years.
For analysis will assume a normal distribution – which would be a typical, reasonable assumption. Ideally, one would look at forecast errors from prior years and see if this is a good fit.
