2021 Sustainability Highlights: Portfolio Company-level Board Diversity

The scope of our data collection includes majority-controlled portfolio companies and investment vehicles (where KKR has more than 50% equity ownership) across Private Equity, Growth Funds, Infrastructure, and Global Impact strategies, and select portfolio companies from the following strategies: Energy, Real Estate, Balance Sheet/Stakes, Credit. Board seats are meant to highlight the composition of a specific board. Diverse directors found on multiple boards occupy more than one diverse seat in the portfolio; therefore, one individual can account for multiple diverse seats.

KKR Global Impact Strategy: Board Diversity

Global Impact monitors diversity at portfolio companies as follows:

  • Global: Gender diversity
  • North America: In addition to gender diversity, the term diversity encompasses (i) Historically Underrepresented Groups, which includes individuals self-identifying as African American, Black, Hispanic, Latino, Native American, or Alaska Native; (ii) Asian American; (iii) individuals self-identifying as LGBTQ for board members only.

KKR Global Impact Strategy: Highlights of Global Impact’s Contribution to the SDGs

This table is for illustrative purposes only. The illustrations on page 26 include all 12 SDGs addressed by Global Impact in 2021 and at least one finalized metric per company in our Global Impact portfolio, but do not include all metrics for every company. Unless otherwise noted, the results are cumulative contributions to the SDGs since baseline, and SDG metrics with percent values expressed as averages since baseline. All figures are rounded totals.


  • Five Star: total loans disbursed by Five Star to its micro-entrepreneurs and self-employed individual clients in India for calendar year 2021.


  • Emsi Burning Glass: metric captures the total number of higher education institutions served by Emsi Burning Glass’ solutions since 2019 baseline. 2019 and 2020 values reflect Burning Glass operations only, as the merger with Emsi occurred in 2021.
  • MasterD: students enrolled in Spain and Portugal as of 2021.
  • Education Perfect: number of students with access to Education Perfect’s platform at the end of 2021.
  • EQuest: metric reflects number of students in EQuest’s portfolio as of 2021.
  • Total students enrolled in Graduation Alliance’s Adult Workforce Diploma and Dropout Recovery Programs in 2021.


  • Axius Water offers end-to-end nutrient management solutions for municipal and industrial wastewater treatment facilities to reduce the harmful effects of biological nutrient pollution. Daily volumes of nutrient chemicals removed are calculated based on the treatment capacity for each product or process provided by Axius Water.


  • BBP provides energy-saving solutions to HVAC systems in commercial and industrial buildings. BBP calculates the percentage change of total customer HVAC system’s energy intensity before and after BBP’s solution was implemented. The result is an average of energy intensity improvements across client projects since baseline reporting.


  • Citation provides health and safety, human resource, and compliance support (through expert advice, internationally recognized quality standards, e-learning modules, guides, templates, etc.) to small and medium-sized enterprises across the United Kingdom. This metric reflects 2021 performance and was calculated by comparing the Injury Incidence Rate per 100,000 employees at Citation’s health and safety clients with the 2021 UK average, sourced from the UK Health and Safety Executive.


  • Refer to SDG 7 BBP endnote. SDG 9 metric captures the CO2 equivalent reduced due to energy efficiency savings generated at BBP’s clients.


  • Re Sustainability is a waste management company that collects and treats municipal solid waste. Viridor is a waste management companies that treats municipal solid waste.


  • Reflects metric tons of hazardous waste treated by Re Sustainability since baseline, such as industrial and medical waste.
  • CMC installs and operates 3D packaging machines, which scan products to produce packaging that fit to product size, supporting retail and logistics clients to reduce corrugate and filler materials on millions of packages shipped. The estimated reduction in paperboard material is for calendar year 2021 and is based on a Life Cycle Assessment (LCA) conducted in the same year. The LCA compared the paperboard used by a traditional packaging machine with its CartonWrap product across a selection of household items.


  • GreenCollar: Australia’s leading carbon markets business and one of the largest carbon abatement developers globally. Australian Carbon Credit Units represent one metric ton of stored carbon dioxide equivalent (tCO2-e) or avoided emissions through approved management activities and methodologies, which is calculated by using a methodology defined by Australia’s Clean Energy Regulator and independently audited.


  • GreenCollar provides Reef Credits where one Reef Credit is equivalent to 1 kilogram of dissolved inorganic nitrogen pollution prevented from reaching the Great Barrier Reef, as a result of more sustainable farming practices via GreenCollar’s engagements with farmers.


  • GreenCollar measures the total land area for accredited carbon projects, which is a subset of total land area under environmental projects as the accreditation process takes time. Metric is as of 2021.


  • KnowBe4 monitors employee susceptibility to simulated phishing security tests before and after implementing its solution. For 2021, the overall Phish-Prone percentage baseline average across all industries and size organizations was 31.4%, meaning just less than a third of an average company’s employee base could be at risk of clicking on a phishing email. However, we found that only 16.1% of those same users failed within 90 days of completing their first KnowBe4 training. After at least a year on the KnowBe4 platform, we found that only 4.8% of those users failed a phishing test. More information on the methodology is available here.

People: Performance Management and Compensation

Compensation and other incentives are not formulaic, but rather judgment and merit driven, and are determined based on a combination of overall Firm performance, individual contribution and performance (as assessed via the Firm’s semiannual review process as well as other inputs), business unit performance, and relevant market and competitive compensation practices for our various businesses and the individual roles/responsibilities within each of those businesses. Awards under our equity plan are subject to timeand/or performance-based vesting requirements. Restricted stock units are generally subject to a service-based vesting condition and vest in equal annual installments over a multiyear period (generally three to five years) from a specified grant date. Certain equity awards may be subject to minimum retained ownership requirements that mandate the employee to retain and not sell a certain percentage of such employee’s equity awards for as long as he or she is an employee of KKR. Certain awards may also be subject to transfer restrictions, prohibiting the sale of equity by the employees for one and two years after vesting.

SASB Index: KKR & Co. Inc. – AUM Disclaimer

References to “assets under management” or “AUM” represent the assets managed, advised or sponsored by KKR from which KKR is entitled to receive management fees or performance income (currently or upon a future event), general partner capital, and assets managed, advised or sponsored by our strategic BDC partnership and the hedge fund and other managers in which KKR holds an ownership interest. We believe this measure is useful to stockholders as it provides additional insight into the capital raising activities of KKR and our hedge fund and other managers and the overall activity in their investment funds and other managed or sponsored capital. KKR calculates the amount of AUM as of any date as the sum of: (i) the fair value of the investments of KKR’s investment funds and the Global Atlantic insurance companies; (ii) uncalled capital commitments from these funds, including uncalled capital commitments from which KKR is currently not earning management fees or performance income; (iii) the fair value of investments in KKR’s co-investment vehicles; (iv) the par value of outstanding CLOs; (v) KKR’s pro rata portion of the AUM of hedge fund and other managers in which KKR holds an ownership interest; (vi) all AUM of KKR’s strategic BDC partnership; and (vii) the fair value of other assets managed or sponsored by KKR. The pro rata portion of the AUM of hedge fund and other managers is calculated based on KKR’s percentage ownership interest in such entities multiplied by such entity’s respective AUM. KKR’s definition of AUM (i) is not based on any definition of AUM that may be set forth in the governing documents of the investment funds, vehicles, accounts or other entities whose capital is included in this definition, (ii) includes assets for which KKR does not act as an investment adviser, and (iii) is not calculated pursuant to any regulatory definitions.

KKR-level ESG Data Tables: Emissions by Scope

Portions of KKR’s 2021 inventory relied on proxy data to develop the resource consumption estimates and resulting emissions impact. As 2021 was still impacted by COVID-19, data access, aggregation and timely transfer was challenging. As such, the inventory was developed with as much primary data as possible, but did apply what we believe to be industry standard and best practices approaches to data estimates, where necessary (e.g., office electricity and fuels, employee commute).
