MCOIX – NYLIM MacKay California Muni Class I Investment Strategy | Morningstar

Morningstar

Strategy

The investment seeks current income exempt from federal and California income taxes. The fund invests at least 80% of its assets (net assets plus any borrowings for investment purposes) in municipal bonds, whose interest is, in the opinion of bond counsel for the issuers at the time of issuance, exempt from federal and California income taxes. It may invest up to 20% of its net assets in municipal bonds subject to the federal alternative minimum tax, and municipal bonds that pay interest that is subject to federal and California income taxes.

Transparency is our policy. Learn how it impacts everything we do

Transparency is how we protect the integrity of our work and keep empowering investors to achieve their goals and dreams. And we have unwavering standards for how we keep that integrity intact, from our research and data to our policies on content and your personal data.

We’d like to share more about how we work and what drives our day-to-day business.

How we make money

We also sell both admissions and sponsorship packages for our investment conferences and advertising on our websites and newsletters.

How we use your personal data

How we approach editorial content

Maintaining independence and editorial freedom is essential to our mission of empowering investor success. We provide a platform for our authors to report on investments fairly, accurately, and from the investor’s point of view. We also respect individual opinions––they represent the unvarnished thinking of our people and exacting analysis of our research processes. Our authors can publish views that we may or may not agree with, but they show their work, distinguish facts from opinions, and make sure their analysis is clear and in no way misleading or deceptive.

To further protect the integrity of our editorial content, we keep a strict separation between our sales teams and authors to remove any pressure or influence on our analyses and research.

Read our editorial policy to learn more about our process.
