California State Teachers' Retirement System -- Moody's affirms CalSTRS' issuer ratings

Rating Action: Moody's affirms CalSTRS' issuer ratings

Global Credit Research - 22 Dec 2020

Baseline credit assessment is downgraded to ba3

New York, December 22, 2020 -- Moody's Investors Service, ("Moody's") affirmed California State Teachers' Retirement System's (CalSTRS) Aa3 long-term issuer rating and P-1 short-term rating. The rating outlook remains stable. At the same time Moody's downgraded CalSTRS' Baseline Credit Assessment (BCA) to ba3, reflecting a weakening of the State Teacher Retirement Plan's (STRP) funded status on a market valued basis.

Under Moody's Government Related Issuers methodology as it applies to public pension managers, recognition is given to CalSTRS' very high dependence on, and support from, its sponsor, the State of California (long-term senior general obligation rating: Aa2 stable). Under Moody's rating methodology for Public Pension Managers a BCA is assigned to CalSTRS, reflecting its intrinsic credit strengths.

Moody's also affirmed the A1 rating with a stable outlook on the California Infrastructure and Economic Development Bank Lease Revenue Bonds, (California State Teachers' Retirement System Headquarters Expansion) Series 2019 (Green Bonds - Climate Bond Certified) ("2019 Lease Revenue Bonds").

RATINGS RATIONALE

The affirmation of CalSTRS' long-term issuer rating one notch below the State of California's rating of Aa2 reflects our view that ongoing weakness in the pension system's funding status positions creditors in a modestly weaker position than the state's general obligation creditors.

Despite economic stresses arising from the COVID-19 pandemic, the outlook for the state remains stable, which supports CalSTRS' long-term issuer rating. CalSTRS' issuer rating is highly dependent on the state, given its underfunded status. .

The key driver of the BCA downgrade to ba3 is a weakening of CalSTRS funding status, which Moody's measures employing market rate adjustments to CalSTRS' published Total Pension Liability. As of June 2020, the STRP's fiduciary net position as a percent of the total pension liability was 71.8% under actuarial assumptions, including an investment rate of return of 7.1%, gross of administrative expenses. Under Moody's alternative approach, the fiduciary net position as a percent of the adjusted pension liability was just 39.3%, using a pension liability index rate of 2.7% to discount pension liabilities. Using Moody's adjustments, CalSTRS' adjusted net pension liability (ANPL) is approximately four times greater than CalSTRS' reported net pension liability of $96.9 billion.
