MDTA Annual Comprehensive Financial Report 2024

DEPOSITS AND INVESTMENTS (CONTINUED) NOTE 2

Interest rate risk. Interest rate risk is the risk that changes in interest rates will adversely affect the fair value of an investment. This risk is higher in debt securities with longer maturities. The MDTA’s Investment Policy limits investment maturities by fund to manage interest rate risk and match maturities with expected funding needs. As a means of limiting its exposure to fair value fluctuations, the MDTA has limited investments in the Operating and Bond Service accounts to one year. The Capital account investment maturities are matched to projected capital spending and the General account is typically limited to five years. The Maintenance and Operations Reserve and Debt Service Reserves are limited to fifteen years. Credit risk. Credit risk is the risk that an issuer or other counterparty to an investment will not fulfill its obligations. The MDTA’s policy allows for investment in obligations of the U.S. Treasury; obligations of U.S. Agencies; obligations of Supranational issuers; money market mutual funds; collateralized certificates of deposit; the Maryland Local Government Investment Pool; repurchase agreements secured by U.S. Treasury Obligations or Federal Agency Obligations; bankers’ acceptances issued by a domestic bank or a federally chartered domestic office of a foreign bank with short-term paper rated Tier-1 by any two Nationally Recognized Statistical Rating Organizations (NRSRO); commercial paper with Tier-1 short-term ratings and issuer long-term ratings of at least single-A from any two NRSROs; and municipal securities rated in at least the second highest rating category by at least one NRSRO. Concentration of Credit Risk. Concentration of credit risk is the risk of loss attributed to the magnitude of a government’s investment in a single issuer. The MDTA’s Investment Policy does not place a limit on the amount of U.S. Government Agency investments but does limit single- issuer exposure to 50%. Supranational exposure is subject to 30% sector and 10% single-issuer limitations. Commercial paper and municipal bond credit exposures are limited to 20% of investments per sector, with single-issuer exposures limited to 5%. More than 5% of the MDTA’s investments were allocated to securities issued by the Federal Home Loan Bank, U.S. Treasury, and Federal Farm Credit Bank representing 19.2%, 14.4%, and 12.2% of total investments, respectively. All of the MDTA’s investments are measured at fair value using the valuation hierarchy. The valuation hierarchy’s three levels include: Level 1 – quoted prices in active markets for identical assets; Level 2 – inputs are observable for the asset, either directly or indirectly, but exclude quoted prices; and Level 3 – inputs are unobservable and may be based on valuation techniques such as market, cost, or income. All of the MDTA’s financial investments are measured using quoted market prices that are categorized as Level 1 in the fair value hierarchy. These financial investments include U.S. Treasury securities, U.S. Agency securities, Supranational securities, Municipal securities, and Corporate Commercial Paper. Other Assets Included in other assets on the accompanying Statement of Net Position is an interest in a rail logistics provider, Canton Development Company (CDC). The CDC offers freight services to industrial, manufacturing, and port-related shippers. The carrying value of the CDC is assessed on an annual basis by reference to the reported value of the MDTA’s interest.
