What we do

A “Family Asset Management Charter” has been established by the family and the management. In addition to setting out the family DNA and strategy, the Charter contains a plan for allocating and distributing its assets and is intended to bring about sustainable growth. 




  • Deciding on an investment strategy: the Charter sets out a number of specific principles of prudence, investment topics and selection criteria for the purpose of asset management. 

  • Deciding on the allocation of assets: Diepensteyn's assets are distributed across real estate, private equity, private equity funds and a portfolio of listed and internationally operating companies and holdings to be held for the long term.

  • Asset management

  • Financial reporting



  • Support with personal development

  • Financial, legal and tax services

  • Real estate management

How we do it: Guidelines for Investing in a Socially Responsible Manner

By definition, doing business has an impact on society. When pursuing business and investment activities, the value created is of significance to society. Diepensteyn has an eye for social and environmental considerations when performing its activities and when in contact with stakeholders. 


The Family Asset Management Charter takes the following as its guiding principles:


  1. Principles for Responsible Investments 

  2. Norwegian Pension Fund exclusion list

  3. Sustainalytics: ESG Rating

  4. The UN's Sustainable Development Goals 

1. Principles for Responsible Investments

The United Nations (UN) supports the Principles for Responsible Investment through the UN Environment Programme Finance Initiative and the UN Global Compact.

Mission of the PRI
"We believe that an economically efficient and sustainable global financial system is essential for creating value in the long term. A system of this kind rewards responsible investment behaviour in the long term and is of benefit to the environment and society as a whole."

The six Principles for Responsible Investment reflect the increasing relevance of environmental, social and corporate governance issues (ESG) for investment practices.  


Diepensteyn has been a signatory of the Principles of Responsible Investments since 2018.

These principles are:

  1. Incorporating ESG issues into the investment analysis and decision-making processes

  2. Incorporating ESG issues into our policy and our management in our position as an active owner

  3. Seeking appropriate disclosure on ESG issues through the projects in which we invest

  4. Promoting the acceptance and implementation of these Principles in the investment industry

  5. Working together to apply the Principles more effectively

  6. Reporting on our activities and progress in implementing the Principles

2. Norwegian Pension Fund exclusion list

Each year, Norges Bank, Norway's central bank, issues a report about responsible investments, describing which new activities the bank has undertaken as part of its ESG investments and, as a result, which public companies they exclude from their investment activities. Diepensteyn has signed the Norwegian Pension Fund exclusion list, meaning it will never invest in companies that appear on this list.

3. Sustainalytics: ESG Ratings

Sustainalytics is a global leader in the field of ESG and corporate governance research and ratings. Over the past 25 years, they have brought prominent ESG researchers and professionals together and monitor more than 10,000 companies with regard to their ESG activities. Diepensteyn integrates the ESG ratings published by Sustainalytics to support the allocation of its assets to public companies.

4. The UN's Sustainable Development Goals

The United Nations has defined 17 Sustainable Development Goals. Together, they constitute the blueprint for a better, more sustainable future for everyone. They are geared toward the global challenges we wish to overcome, and include issues relating to poverty, inequality, climate, harm to the environment, prosperity, peace and justice. The goals are all interconnected. In order to "leave no-one behind", it is important that each goal is reached by 2030.
When allocating its assets, Diepensteyn evaluates the integration of one or more goals.
