Stock Performance Graph Comcast The graph below compares the yearly percentage change in the cumulative total shareholder return on Comcast’s Class A common stock during the five years ended December 31, 2015 with the cumulative total returns on the Standard & Poor’s 500 Stock Index and with a select peer group consisting of us and other companies engaged in the cable, communications and media industries.
This peer group consists of us, as well as Cablevision Systems Corporation (Class A), DISH Network Corporation (Class A), DirecTV Inc.  (included through July 24, 2015, the date of acquisition by AT&T Corp. ) and Time Warner Cable Inc.  (the “cable subgroup”), and Time Warner Inc. , Walt Disney Company, Viacom Inc.  (Class B), Twenty-First Century Fox, Inc.  (Class A), and CBS Corporation (Class B) (the “media subgroup”).
The peer group was constructed as a composite peer group in which the cable subgroup is weighted 63% and the media subgroup is weighted 37% based on the respective revenue of our Cable Communications and NBCUniversal segments.
The graph assumes $100 was invested on December 31, 2010 in our Class A common stock and in each of the following indices and assumes the reinvestment of dividends.
## Table 0 ##
NBCUniversal NBCUniversal is a wholly owned subsidiary of NBCUniversal Holdings and there is no market for its equity securities.
The information systems used by our domestic dough manufacturing and supply chain centers are an integral part of the quality service we provide our stores.
We use routing strategies and software to optimize our daily delivery schedules, which maximizes on-time deliveries.
Through our strategic dough manufacturing and supply chain center locations and proven routing systems, we achieved delivery accuracy rates of approximately 99% during 2007.
Our supply chain center drivers unload food and supplies and stock store shelves typically during non-peak store hours, which minimizes disruptions in store operations.
International During 2007, our international segment accounted for $126.9 million, or 9%, of our consolidated revenues.
We have 566 franchise stores in Mexico, representing the largest presence of any QSR company in Mexico, 467 franchise stores in the United Kingdom, 405 franchise stores in Australia, 289 franchise stores in South Korea, 277 franchise stores in Canada and over 100 franchise stores in each of Japan, India, Taiwan and France.
The principal sources of revenues from our international operations are royalty payments generated by retail sales from franchise stores and sales of food and supplies to franchisees in certain markets.
We have grown by more than 1,000 international stores over the past five years.
While our stores are designed for delivery and carry-out, which are less capital-intensive than dine-in, we empower our managers and franchisees to adapt the standard operating model, within certain parameters, to satisfy the local eating habits and consumer preferences of various regions outside the contiguous United States.
Currently, most of our international stores are operated under master franchise agreements, and we plan to continue entering into master franchise agreements with qualified franchisees to expand our international operations in selected countries.
We believe that our international franchise stores appeal to potential franchisees because of our well-recognized brand name, the limited capital expenditures required to open and operate our stores and our system’s favorable store economics.
The following table shows our store count as of December 30, 2007 in our top ten international markets, which account for 77% of our international stores.
## Table 1 ##
Our franchise program As of December 30, 2007, our 4,584 domestic franchise stores were owned and operated by our 1,243 domestic franchisees.
The success of our franchise formula, which enables franchisees to benefit from our brand name with a relatively low initial capital investment, has attracted a large number of motivated entrepreneurs as franchisees.
As of December 30, 2007, the average domestic franchisee operated approximately three to four stores and had been in our franchise system for twelve years.
At the same time, only seven of our domestic franchisees operated more than 50 stores, including our largest domestic franchisee, which operates 143 stores.
Domestic franchisees We apply rigorous standards to prospective franchisees.
We generally require prospective domestic franchisees to manage a store for at least one year before being granted a franchise.
This enables us to observe the operational and financial performance of a potential franchisee prior to entering into a long-term contract.
We also restrict the ability of domestic franchisees to become involved in other businesses, which focuses our franchisees’ attention on operating their stores.
As a result, the vast majority of our franchisees come from within the Domino’s Pizza system.
We believe these standards are unique to the franchise industry and result in qualified and focused franchisees operating their stores.
DOMINO’S PIZZA, INC.  AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) Management estimated the fair value of each option grant made during 2014, 2013 and 2012 as of the date of the grant using the Black-Scholes option pricing method.
Weighted average assumptions are presented in the following table.
The risk-free interest rate is based on the estimated effective life, and is estimated based on U. S.  Treasury Bond rates as of the grant date.
The expected life (years) is based on several factors, including, among other things, the vesting term and contractual term as well as historical experience.
The expected volatility is based principally on the historical volatility of the Company’s share price.
## Table 2 ##
Option valuation models require the input of highly subjective assumptions.
In management’s opinion, existing models do not necessarily provide a reliable single measure of the fair value of the Company’s stock options, as changes in subjective input assumptions can significantly affect the fair value estimate.
Other Equity-Based Compensation Arrangements The Company granted 10,640 shares, 24,540 shares and 22,420 shares of restricted stock in 2014, 2013 and 2012, respectively, to members of its board of directors.
These grants generally vest oneyear from the date of the grant and have a fair value equal to the market price of the Company’s stock on the grant date.
The Company recorded total non-cash compensation expense of $0.8 million, $1.0 million and $0.8 million in 2014, 2013 and 2012, respectively, related to these restricted stock awards.
All non-cash compensation expense amounts are recorded in general and administrative expense.
As of December 28, 2014, there was approximately $0.1 million of total unrecognized compensation cost related to these restricted stock grants.
The Company granted 119,670 shares, 312,330 shares and 282,170 shares of performance-based restricted stock in 2014, 2013 and 2012, respectively, to certain employees of the Company.
The performance-based restricted stock awards granted in 2012 are separated into three tranches and have time-based and performance-based vesting conditions with the last tranche vesting three years from the issuance date.
The performance-based restricted stock awards granted in 2013 and 2014 are separated into four tranches and have time-based and performance-based vesting conditions with the last tranche vesting four years from the issuance date.
These awards also contain provisions for accelerated vesting upon the retirement of holders that have achieved specific service and age requirements.
These awards are considered granted for accounting purposes when the performance target is set, which is generally in the fourth quarter of each year.
The Company recorded total non-cash compensation expense of $12.4 million, $14.1 million and $11.5 million in 2014, 2013 and 2012, respectively, related to these awards.
