For the second year in a row, the board of Google’s parent firm Alphabet is urging shareholders to shoot down an investor proposal for the company to report on its alleged gap in pay between women and men.

Alphabet investor Arjuna Capital’s stockholder proposal will go before shareholders during the Mountain View tech giant’s annual meeting June 6.

“While Google reports women make 99.7 percent of that of their male counterparts after statistical controls, Payscale reports a 15.2 percent mean pay gap at Google, and employee leaked data shows salary gaps in five out of six levels,” the proposal said.

The report should examine “the risks to the company associated with emerging public policies on the gender pay gap,” according to the proposal, contained in a proxy statement that the firm filed Friday with the Securities and Exchange Commission.

Alphabet’s board responded that it had “carefully considered” the proposal and believes it is not in the best interests of the company and its shareholders.

“The compensation structure at Google is designed to prevent gender pay differences by setting pay targets by job,” the board said.

“We regularly take actions to ensure the diversity and equality of our practices.”

Alphabet is under federal investigation over its compensation for women, with the Department of Labor accusing it of “extreme” gender discrimination. The company has responded to those claims in a blog post, saying it is “committed to treating, and paying, people fairly and without bias with regard to factors like gender or race.”

Google is also facing a lawsuit from four former female employees who seek class action status for their legal action and claim Google discriminated against women and broke California law by slotting women into lower salary levels than men, giving women lower-paying jobs, promoting women more slowly and less frequently, and generally paying female employees less than men for similar work.

Google has said it disagrees with the “central allegations” of the suit.

“We work really hard to create a great workplace for everyone, and to give everyone the chance to thrive here,” spokeswoman Gina Scigliano said in January. “Job levels and promotions are determined through rigorous hiring and promotion committees, and must pass multiple levels of review, including checks to make sure there is no bias in these decisions.”

Arjuna last year submitted a similar proposal to stockholders, and it was nixed in early voting by investors.
