Table of ContentsATMOS ENERGY CORPORATIONNOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

The following tables set forth by level, within the fair value hierarchy, the Pension Plan's assets at fair value as of September 30, 2025 and 2024. As required by authoritative accounting literature, assets are categorized in their entirety based on the lowest level of input that is significant to the fair value measurement. The methods used to determine fair value for the assets held by the Pension Plan are fully described in Note 2 to the consolidated financial statements. Investments in our common/collective trusts and limited partnerships that are measured at net asset value per share equivalent are not classified in the fair value hierarchy. The net asset value amounts presented are intended to reconcile the fair value hierarchy to the total investments. In addition to the assets shown below, the Pension Plan had net accounts receivable of $5.1 million and $0.7 million at September 30, 2025 and 2024, which materially approximates fair value due to the short-term nature of these assets. Assets at Fair Value as of September 30, 2025 Level 1Level 2Level 3Total (In thousands)Investments:Common stocks$284,573 $— $— $284,573 Money market funds— 16,293 — 16,293 Registered investment companies123,022 — — 123,022 Government securities:Mortgage-backed securities— 26,101 — 26,101 U.S. treasuries15,021 26 — 15,047 Corporate bonds— 32,517 — 32,517 Asset-backed securities— 1,475 — 1,475 Total investments measured at fair value$422,616 $76,412 $— 499,028 Investments measured at net asset value:Common/collective trusts (1)95,
