Japan GPIF Invests $3.7 Billion in Morningstar Gender Diversity Index

The index is designed to emphasize Japanese companies with strong gender and diversity policies.


Japan’s $1.4 trillion Government Pension Investment Fund has allocated 500 billion yen ($3.7 billion) to track the Morningstar Japan ex-REIT Gender Diversity Tilt Index. The pension giant said it began passive management based on the index in March.

The index aims to pursue objectives that align with environmental, social and governance standards in reference to gender diversity and was constructed using the data and scoring methodology of Equileap, a provider of data and insights on gender equality. The index is designed to emphasize companies in the Japanese market that have strong gender diversity policies rooted in their corporate culture and that provide equal opportunities to employees, regardless of their gender.

GPIF said it made its decision to invest in the index after evaluating environmental, social and governance indices for Japanese equities based on the information submitted through the Index Posting System, a framework used by the pension fund to gather information on various equity and bond indexes.

According to Morningstar, the Japan ex-REIT Gender Diversity Tilt Index is comprised of 928 constituents, covering a range of domestic listed companies within 10 different sectors. The top constituents of the index are Toyota Motor, Sony Group and Mitsubishi UFJ Financial Group, which have weightings of 4.11%, 3.06% and 2.18%, respectively. Individual security weights are capped at 5%. The company said that with industry weights neutralized, the index has a low tracking error and low turnover ratio.

“Based on our belief that the sustainable growth of investee companies and the whole market is crucial for the stable investment returns from assets under management, GPIF takes gender diversity, as one of the ESG factors, into consideration in its passive investment in domestic and foreign equities,” GPIF President Miyazono Masataka said in a release. “This adjustment of ESG portfolio is conducted as part of our risk management of the entire portfolio.”

Companies within the index are ranked in descending order by their Equileap Gender Equality Score and divided into five equally sized groups. The top group includes companies with the highest scores, while the bottom group includes companies with the lowest scores. The tilt factors are then applied by multiplying the weight of each company in the parent index by the tilt factor to determine its weight in the index.

Equileap assigns a gender equality score to companies based on 19 criteria among four categories with different weightings. Category A is gender balance in leadership and workforce; category B is equal compensation and work-life balance; category C is policies promoting gender equality; and category D is commitment, transparency, and accountability.

Eamples of the 19 criteria include the gender balance of senior management, the gender pay gap and policies around parental leave and sexual harassment. Equileap also investigates a company’s legal record and will place those involved in legal cases regarding gender-based violence and discrimination on what it calls the “Alarm Bell List.” Companies on that list are ineligible to be included in the index for a year.

The index is reconstituted every year in December and rebalanced quarterly in March, June, September and December.
