Change to the announced effective date: January 1, 2019 effective date for the Industry Classification Benchmark (ICB) enhancement has been extended to later in TBD 2019. To help clients transition to the new ICB structure, the legacy ICB Universe product will continue to be provided to clients in parallel throughout 2019. And the discontinuation of Russell Global Sectors (RGS) has been extended to later in 2019.

An industry classification system allows investors and other market participants to segment and evaluate the global economy in a systematic and holistic way. It provides a standardized framework to research individual areas of the economy, conduct peer group analysis and classify companies on both a top-down and bottom-up basis. An industry classification system allows users to assign individual companies to both aggregate industry groupings and, with increasing levels of detail, to sectors and subsectors that reflect companies’ specialist areas of business.

A well-constructed classification system can also be used to track the performance and evolution of industries, supersectors, sectors, subsectors and companies over time. Therefore, as industries evolve and new forms of economic activity rise to prominence, a classification scheme needs to adapt to reflect those changes.

In 2019, the Industry Classification Benchmark (ICB®) will be enhanced to ensure that its company categorization structure meets the needs of today’s investment professionals.

  • Following the completion of the “FTSE Russell Client Consultation for Integrating Industry Classification Structures” and based on additional research and client feedback, effective January 1, 2019, the ICB structure will be improved and expanded to include:
    • 11 Industries
    • 20 Supersectors
    • 45 Sectors
    • 171 Subsectors
  • Also effective January 1, 2019, the Russell Global Sectors (RGS) classification scheme will be discontinued and its clients will be transitioned to the updated ICB scheme.

In this FTSE Russell Insights we describe the enhancements to the ICB framework, outline the rationale for key changes to its structure and summarize the impact of the proposed changes.

What is ICB?

ICB is a globally recognized standard for categorizing companies and securities, operated and managed by FTSE Russell. ICB is widely used both by the world’s stock exchanges and as the underlying framework for over US$250B in benchmarked assets in sector-based fund products.

ICB provides four levels of classification, from Industry to Supersector, Sector and Subsector. Each company in the ICB Universe is allocated to the Subsector that most closely represents the nature of its business. This allocation is determined by the company’s primary source of revenue and other publicly available information. Where revenue information is unavailable or insufficient, a company will be allocated to that Subsector whose definition most closely coincides with the description of the company’s business as stated in its annual report, listing prospectus or regulatory filings.

Approximately 100,000 securities worldwide are classified by the ICB system, providing a comprehensive data source for investment research, portfolio management and asset allocation. Funds are constructed based on ICB Industries and Supersectors, and the global scope of the classification framework also allows for comparative analysis between sectors and industries worldwide as an investment decision-support tool.

FTSE Russell leadership in company classification

FTSE Russell is a pioneer in company classification. When the FT-Actuaries All-Share Index (now the FTSE All-Share® Index) of UK equities was launched in 1962, its index committee carried out the first comprehensive and logical classification of companies by industry that the investment world had seen. The constituents of the All-Share Index were allocated to one of eight industry groups (capital goods, consumer durables, consumer non-durables, chemicals, oil, shipping, financials and miscellaneous), with companies then allocated to homogeneous sub-groups within four of these industry groups.

The FT-Actuaries All-Share Index classification structure was reviewed and modified in 1970 and again in 1994 to reflect a more codified approach and changes in the structure of the UK equity market. In 1999-2000 the system was expanded and adapted for use in the classification of the global equity markets, in particular as the underlying sector classification framework for the FTSE Eurotop and the FT/S&P Actuaries World Indices, both predecessors of the current FTSE Global Equity Index Series.

ICB, a comprehensive classification framework for the global equity markets, was launched by FTSE and Dow Jones in 2005 and has remained largely unchanged in structure since then (in 2011, FTSE became the sole owner of ICB).

As part of the FTSE and Russell Indexes integration effort following the 2014 acquisition of Russell Investments by the London Stock Exchange Group, the taxonomies and methodologies of both the ICB and RGS systems were reviewed. In March 2017, FTSE Russell consulted the market on the unified classification structure that would combine the best of both systems, as well as reflect changes in the way investors view the structure of the global equity markets.

What is changing at the headline level?

At the headline level, the enhancements to the ICB structure mean that from January 1, 2019 ICB will include 11 Industries, 20 Supersectors, 45 Sectors and 171 Subsectors (Figure 1).

Compared with the current ICB structure, the number of Industries and Supersectors increases by one, the number of Sectors by four and the number of Subsectors by 57. For RGS users, nine Sectors become 11 Industries, the intermediate Subsector level maps to two ICB tiers (the Supersector and Sector levels) and 157 RGS Industries become 171 ICB Subsectors.

Both ICB and RGS users will benefit from the added granularity under the new system, particularly at the Subsector level. Users of the current RGS scheme will also gain from the addition of a classification level within ICB’s four-tiered system.

The ICB numeric code system has also been redesigned to better accommodate possible future additions and changes, paving the way for future expansion beyond the current coverage as FTSE Russell continues to expand its product offering to provide more data solutions and investment tools across asset classes worldwide.

What are the key changes?

In addition to the enhanced Subsector granularity, key changes to the ICB at the broadest headline level include the addition of Real Estate as an ICB Industry, the expansion of the Telecommunications Industry and the adoption of Consumer Discretionary and Consumer Staples (Figure 2). The ICB Oil and Gas Industry is renamed Energy.

Addition of Real Estate as the 11th ICB Industry

The real estate segment has reached critical mass in global equity markets. As of July 31, 2017, real estate stocks − including real estate investment trusts (REITs) − comprised 4.1% of the FTSE Global All Cap Index, representing nearly US$2 trillion of investable market capitalization.

Listed real estate companies provide access to commercial real estate investments with the added liquidity, transparency and regulation associated with investing in publicly traded stocks. Additionally, real estate equity generally provides the potential of competitive long-term rates of return supported by regular dividend payments.

The correlation of real estate stocks to banks, financial services and insurance companies has declined over the past decade, supporting the case for real estate to be treated as a distinct activity from that of other companies in the financials sector (Figure 3). The lower correlation of listed real estate equity compared to other equities in the medium to long run may help diversify investment portfolios relative to other asset classes.

The FTSE Russell consultation proposed the addition of Real Estate as the 11th ICB Industry and subsequent market feedback strongly supported this proposal.
In its response to the FTSE Russell market consultation, real estate industry expert National Association of Real Estate Investment Trusts (NAREIT) said that:

“These proposed changes [to ICB] would appropriately recognize, clarify and illuminate the growing presence, significance and specialization of stock exchange-listed real estate companies, including listed Equity REITs and other listed real estate companies engaged in the acquisition, development, ownership, leasing and management of real estate.”

 - Michael Grupe, Executive Vice President, Research & Investor Outreach at the National Association of Real Estate Investment Trusts (NAREIT)

The European Public Real Estate Association (EPRA) also expressed support for the new ICB Real Estate Industry segment:

"ICB's elevation of Real Estate as its 11th Industry reflects the growth of listed real estate, which is driven by the introduction of REITs globally and long-term returns. The reclassification confirms the merits of listed real estate as a standalone asset class."

- Ali Zaidi, Director of Research & Indices at the European Public Real Estate Association (EPRA)

Given the growth of REITs globally, the new ICB structure will maintain REITs as a distinct Sector (separate from the Real Estate Investment & Services Sector within the Real Estate Industry and Supersector), with added granularity at the Subsector level (Figure 4).

However, because Mortgage REITs derive revenue from real estate financing rather than from real estate itself, they will remain in the Financials Industry within the Financial Services Supersector, albeit with additional granularity at the Subsector level (Diversified, Commercial, Residential).

Although the weight of the ICB Financials Industry will be reduced in proportion to the weight of real estate companies assigned to the new Real Estate Industry, the ICB Financials Industry is projected to retain the largest Industry weight in the FTSE Global All Cap Index based on June 2017 market capitalization weights.

Expansion of the Telecommunications Industry

Globally, the Telecommunications Industry continues to evolve and gain in significance. The new ICB structure reflects this trend by expanding the Industry via the addition of companies from the technology (Telecommunications Equipment) and media (Cable Television Services) segments to align with the Telecommunications-Media-Technology (TMT) grouping commonly referenced by investment professionals (Figure 5).

RGS users will also gain a 10th Industry via the segmentation of Telecommunications companies from Utilities, where they are currently located in the RGS framework.

Other changes include the creation of the Telecommunications Services Subsector − combining Fixed Line Telecommunications and Mobile Telecommunications companies as these business lines continue to converge − and the Cable Television Services Subsector, which are grouped at the Sector level as Telecommunications Service Providers. All Telecommunications companies including Telecommunications Equipment are grouped at the Industry and Supersector levels.

Adoption of Consumer Discretionary and Consumer Staples Industries

The segmentation of companies involved in the provision of consumer goods and services into Consumer Staples and Consumer Discretionary segments has become a standard approach among investment professionals. This preference reflects the tendency of stocks within the two segments to exhibit distinct risk/return characteristics during different phases of the economic cycle. As such, the ICB Consumer Services and Consumer Goods Industries will transition to the new ICB Consumer Discretionary and Consumer Staples Industries (Figures 6 and 7).

As their name suggests, Consumer Staples companies tend to continue to generate profits during periods of recession, while Consumer Discretionary companies tend to suffer more during recessions but have increased sensitivity to economic upswings.

The new ICB Consumer Discretionary and Consumer Staples Industries are a blend of the existing ICB Consumer Goods and Consumer Services Industries. A preliminary analysis undertaken by FTSE Russell based on the FTSE Global All Cap Index shows that a majority of the weight in the existing ICB Consumer Goods Industry shifts to the new ICB Consumer Staples Industry, while a majority of the weight in the existing Consumer Services Industry shifts to the new ICB Consumer Discretionary Industry.

For existing ICB users, several Subsectors are further segmented to add granularity: for example, the existing Specialized Consumer Services Subsector will be divided into seven new Subsectors. Additional granularity is also provided in the Food Products and Personal Products ICB Subsectors.

For existing RGS users, the Airlines Subsector and the Electronic Entertainment Subsector move from Industrials and Technology, respectively, to Consumer Discretionary within the new ICB framework.

Other highlights

Other notable changes for existing ICB or RGS users include:

  • Energy: The renaming of the existing ICB Oil and Gas Industry as the Energy Industry to align with current market practice, the creation of new Renewable and Non-Renewable Energy Sectors and the shift of the ICB Coal Subsector from Basic Materials to Energy to group together energy segments (oil, gas and coal).
  • Airlines: Given the consumer-sensitive nature of much air travel, ICB will maintain the distinction between passenger airlines and freight air transport (this will be a change to RGS users). Passenger airlines will continue to be assigned to the Airlines Subsector placed within the new ICB Consumer Discretionary Industry, while freight air transport will remain within the Delivery Services Subsector within the ICB Industrials Industry. Airlines demonstrated similar levels of correlation to companies classified as Industrials and with companies classified as Consumer Discretionary over the long-term, despite slightly higher near-term correlation with Industrials companies.
  • Consumer Digital Services: ICB’s existing Internet segment will be renamed and redefined as Consumer Digital Services within the Technology Industry, which include companies involved in digital platforms that generate revenues from advertising, content delivery and other virtual products related to consumers. Although companies within this Subsector may serve consumers, revenues are derived primarily from providing technology services.

What is the projected turnover impact of the structural changes to ICB?

The effect of the changes at the ICB Industry level is shown in Figure 8. The table reflects the number and percentage weight of constituents within each of the eleven new ICB Industries, as well as an analysis of changes based upon the FTSE Global All Cap Index. The number of additions and deletions with reference to the existing ICB structure is shown, as well as the additions and deletions as a percentage of the overall index.

A single standard for classifying companies

ICB provides a comprehensive, single classification standard, enabling investment professionals, financial analysts and other market participants to categorize companies on both a top-down and bottom-up basis. The enhancements effective in January 2019 to ICB will ensure that it continues to meet the needs of those investing across an evolving global equity market and accommodate future enhancements as FTSE Russell expands its capabilities beyond the current coverage.
