# Custer County Montana Custer County Montana is a Pension Fund based in Miles City, United States. ## Overview - **Organization type:** Pension Fund - **Headquarters:** Miles City, United States - **Region:** North America - **Address:** Miles City, MT, United States - **Founded:** 1877 - **Assets under management:** Undisclosed (Altss estimate: ~$37M investment-pool assets) - **Website:** custercountymt.com ## Regulatory record - **Reports private funds:** No ## About Custer County was established in 1877 in southeastern Montana, with Miles City as its county seat. As a political subdivision of the state, it is not a family office or a private investment firm — it is a local government entity whose "portfolio" consists of public funds managed under interlocal agreements with the state of Montana. The county participates in the Short-Term Investment Pool (STIP) administered by the Montana Board of Investments, which pools idle cash from over 300 local governments and invests it in fixed-income securities such as U.S. Treasury bills, agency notes, and high-grade commercial paper. The county's investment posture is governed by state statute, not a committee of principals. Montana law requires public funds to prioritize safety, liquidity, and yield, in that order. The Board of Investments manages the STIP as a 2a-7-like pool, aiming for a stable net asset value and short duration. Custer County's exposure is therefore entirely in liquid, low-risk public fixed-income instruments. The county itself does not directly allocate to private equity, venture capital, real estate funds, or hedge funds. Altss estimates Custer County's pooled public funds at roughly $37 million, a figure derived from county financial disclosures and typical cash-flow patterns for a jurisdiction of its population — about 12,000 residents. The county's economic base is agricultural: cattle ranching and dryland farming. Its other assets include physical properties such as the 1939 Custer County Courthouse at 1010 Main Street, the county high school, and public parks like Riverside Park. The county employs workers whose retirement benefits flow through the Montana Public Employee Retirement Administration (MPERA), a separate state-run defined-benefit plan. Custer County's most recent operational adjustment was the routine annual MACo legislative briefing in 2024, where the Montana Association of Counties discussed STIP interest-rate returns and property-tax policy with member counties. What distinguishes Custer County from a family office or pension fund is its legal architecture: it is a mandatory participant in a state-managed pool, not a discretionary allocator. Its "investment office" is functionally the Montana Board of Investments' fixed-income desk in Helena. The county's own elected commissioners handle budgeting and deposits, but asset-allocation decisions happen at the state level. This makes Custer County a tiny but representative unit of Montana's $6 billion-plus public-funds ecosystem — a statutory node in a statewide liquidity system, not an active investment organization. ## Sectors - Public Equities - Fixed Income ## Questions ### Is Custer County Montana an active investor or a passive participant in a state pool? Custer County is a passive participant. It places idle public cash into Montana's Short-Term Investment Pool (STIP), which is managed by the Montana Board of Investments. The county commissioners decide how much to deposit, but all asset-allocation, credit, and duration decisions are made at the state level under a statutory mandate to prioritize safety and liquidity above yield. ### Does Custer County invest in private equity, venture capital, or real estate funds? No. The county's investable assets sit in the STIP, which is restricted to short-term fixed-income instruments such as U.S. Treasury obligations, federal agency securities, and high-grade commercial paper. The county does not have a separate direct-investment program for alternatives. ### What is the estimated size of Custer County's public funds pool? Altss estimates the county's pooled public funds at approximately $37 million, based on county financial reports and cash-flow profiles typical for a rural Montana jurisdiction of roughly 12,000 residents. The county itself has never publicly disclosed a consolidated investment AUM figure because it operates as a depositor, not a fund manager. ### How is Custer County's pension obligation handled? County employee retirement benefits are administered by the Montana Public Employee Retirement Administration (MPERA), a defined-benefit state plan. Custer County makes statutorily required employer contributions to MPERA, but the county does not manage or direct the pension fund's assets — MPERA's own board and staff oversee its $6 billion-plus portfolio independently. ## Related profiles - [Central Kansas Community Foundation](https://altss.com/profile/central-kansas-community-foundation-ckcf) - [Foothills Community Foundation](https://altss.com/profile/foothills-community-foundation) --- Last updated: 2026-07-10T22:17:13.000Z Canonical page: https://altss.com/profile/custer-county-montana Maintained by Altss — https://altss.com — methodology: https://altss.com/methodology
