MTRTX Investment Objective and Strategy

MainStay MacKay Total Return Bond Fund describes its objective and strategy as follows, from its latest prospectus filed with the SEC by New York Life Investments Funds Trust.

Investment objective

The Fund seeks total return.

Principal investment strategy

"The Fund, under normal circumstances, invests at least 80% of its assets (net assets plus any borrowings for investment purposes) in bonds, which include all types of debt securities, such as: debt or debt-related securities issued or guaranteed by the U.S. or foreign governments, their agencies or instrumentalities; obligations of international or supranational entities; debt securities issued by U.S. or foreign corporate entities; zero coupon bonds; municipal bonds; mortgage-related and other asset-backed securities; and loan participation interests. The Fund will generally seek to maintain a weighted average duration within 2.5 years (plus or minus) of the duration of the Bloomberg Barclays U.S. Aggregate Bond Index. Duration is a measure used to determine the sensitivity of a security/portfolio to changes in interest rates.

Duration incorporates a bond's yield, coupon, final maturity and call features into one number, expressed in years, that indicates how price-sensitive a bond or portfolio is to changes in interest rates. The longer the duration of a security/portfolio, the more sensitive it will be to changes in interest rates. As of December 31, 2017, the weighted average duration of the Fund and Bloomberg Barclays U.S. Aggregate Bond Index were 5.75 years and 5.98 years, respectively. At least 65% percent of the Fund's total assets will be invested in investment grade debt securities, as rated by an independent rating agency, such as rated BBB- or better by Standard & Poor's Ratings Services (""S&P"") or Baa3 or better by Moody's Investors Service, Inc. (""Moody's"") when purchased, or if unrated, determined by the Subadvisor to be of comparable quality.

The Fund may also invest up to 20% of its total assets in securities rated below investment grade by an independent rating agency or, if not rated, determined to be of equivalent quality by the Subadvisor. Securities that are rated below investment grade by independent rating agencies are commonly referred to as high-yield securities or ""junk bonds."" If independent rating agencies assign different ratings for the same security, the Fund will use the higher rating for purposes of determining the credit quality. The Fund may invest in mortgage dollar rolls, to-be-announced (""TBA"") securities transactions, variable rate notes and floaters. The Fund may invest up to 20% of its total assets in securities denominated in foreign currencies. To the extent possible, the Fund will attempt to protect these investments against risks stemming from differences in foreign exchange rates.

The Fund may also invest in derivatives such as futures, options and swap agreements to try to enhance returns or reduce the risk of loss by hedging certain of its holdings. Commercial paper must be, when purchased, rated in the highest rating category by an independent rating agency, such as A-1 by S&P or Prime-1 by Moody's, or if unrated, determined by the Subadvisor to be of comparable quality. The Fund's principal investments may have fixed or floating rates of interest. Investment Process: In pursuing the Fund's investment strategy, MacKay Shields LLC, the Fund's Subadvisor, conducts a continuing review of yields and other information derived from a database which it maintains in managing fixed-income portfolios. Fundamental economic cycle analysis, credit quality and interest rate trends are the principal factors considered by the Subadvisor in managing the Fund and determining whether to increase or decrease the emphasis placed upon a particular type of security or industry sector within the Fund's investment portfolio.

Maturity duration shifts adjustments are based on a set of investment decisions that take into account a broad range of economic, fundamental and technical indicators. The Subadvisor may sell a security if it no longer believes that the security will contribute to meeting the investment objective of the Fund. In considering whether to sell a security, the Subadvisor may evaluate, among other things, the condition of the economy, meaningful changes in the issuer's financial condition, and changes in the condition and outlook in the issuer's industry."
