Schedule HC-B: Securities Guide¶
Form: FR Y-9C (Consolidated Financial Statements for Holding Companies) Schedule: HC-B - Securities Frequency: Quarterly Purpose: Detail all debt securities (and selected equity disclosures) held by the BHC
Overview¶
Schedule HC-B provides a comprehensive breakdown of the institution's securities portfolio by: - Security Type: Treasury, U.S. agency, munis, MBS, ABS, structured products, other debt - Accounting Classification: Held-to-Maturity (HTM) vs. Available-for-Sale (AFS) - Valuation Basis: Amortized cost and fair value for each classification
Accounting Classifications¶
| Classification | Carrying Value | Unrealized G/L Treatment |
|---|---|---|
| HTM | Amortized cost | Not recognized until sale (FV disclosed) |
| AFS | Fair value | AOCI (equity) |
| Equity (M.5) | Fair value | Income statement (ASU 2016-01) |
Column Scheme (CURRENT FORM)¶
The current FR Y-9C HC-B reports four columns for each line item, in this order:
COLUMN A: Held-to-maturity — AMORTIZED COST (carrying value of HTM)
COLUMN B: Held-to-maturity — FAIR VALUE (disclosure only)
COLUMN C: Available-for-sale — AMORTIZED COST (cost basis of AFS)
COLUMN D: Available-for-sale — FAIR VALUE (carrying value of AFS)
Verified against item 1 (A=BHCK0211 HTM amortized cost, B=BHCK0213 HTM fair value, C=BHCK1286 AFS amortized cost, D=BHCK1287 AFS fair value) and item 8 totals (A=BHCK1754 HTM total, B=BHCK1771 HTM FV total, C=BHCK1772 AFS amortized-cost total, D=BHCT1773 AFS FV total).
CSV layout note: the companion
csv/HC_B_SECURITIES.csvcarries four MDRM columns namedmdrm_afs_amortized_cost,mdrm_afs_fair_value,mdrm_htm_amortized_cost,mdrm_htm_fair_value. These are mapped by meaning, not by form column position: -mdrm_htm_amortized_cost← Column A -mdrm_htm_fair_value← Column B -mdrm_afs_amortized_cost← Column C -mdrm_afs_fair_value← Column D

Detailed Line Item Analysis¶
(Tables list MDRM codes by form column: A = HTM amortized cost, B = HTM fair value, C = AFS amortized cost, D = AFS fair value.)
Item 1: U.S. Treasury Securities¶
| Column | MDRM | Description |
|---|---|---|
| A (HTM Cost) | BHCK0211 | HTM Treasuries at amortized cost |
| B (HTM FV) | BHCK0213 | HTM Treasuries at fair value |
| C (AFS Cost) | BHCK1286 | AFS Treasuries at amortized cost |
| D (AFS FV) | BHCK1287 | AFS Treasuries at fair value |
Characteristics: Zero credit risk (U.S. government backing); highly liquid; LCR Level 1 HQLA.
Item 2: U.S. Government Agency Obligations (Excluding MBS)¶
| Column | MDRM | Description |
|---|---|---|
| A (HTM Cost) | BHCKHT50 | HTM agency obligations at amortized cost |
| B (HTM FV) | BHCKHT51 | HTM agency obligations at fair value |
| C (AFS Cost) | BHCKHT52 | AFS agency obligations at amortized cost |
| D (AFS FV) | BHCKHT53 | AFS agency obligations at fair value |
Includes: FHLB debentures, SBA securities, TVA bonds, and other non-MBS agency obligations. Excludes: All MBS (reported in item 4).
Code history: the current form uses BHCKHT50–HT53 (open since 2018-06-30). These replaced the retired pairs BHCK1289/1290 (HTM, closed 2018-03-31). The old repo build used BHCKJF77/JF78 for AFS agency — those codes actually mean "Total assets/liabilities of ABCP conduit VIEs" and were a concept error, now corrected.

| C (AFS Cost) | BHCK8498 | AFS munis at amortized cost |
| D (AFS FV) | BHCK8499 | AFS munis at fair value |

Equity Securities (related HC reconciliation)¶

Risk Weight Mapping (Basel III)¶
| Security Type | Risk Weight | HQLA Category |
|---|---|---|
| U.S. Treasury | 0% | Level 1 |
| GNMA MBS | 0% | Level 1 |
| GSE Debt & MBS | 20% | Level 2A |
| Munis (General Obligation) | 20% | Level 2B (if liquid) |

| Below IG Corporate | 150% | Not HQLA |
Key Analytical Ratios¶
Portfolio Composition¶
Treasury % = Item 1 / Item 8
Agency % = (Item 2 + 4.a + 4.b.(1) + 4.b.(2) + 4.c agency lines) / Item 8
Non-Agency % = (4.b.(3) + 4.c.(2)(b)) / Item 8
ABS+SFP % = Item 5 / Item 8
HTM vs. AFS Mix¶
HTM % = Item 8 Col A (BHCK1754) / (Col A + Col C cost totals)
- Higher HTM % = more locked-in positions, less AOCI volatility
- Lower HTM % = more mark-to-market exposure flowing through AOCI
Unrealized Gain/Loss¶
AFS Unrealized = AFS Fair Value - AFS Amortized Cost = BHCT1773 - BHCK1772 (flows to AOCI)
HTM Unrealized = HTM Fair Value - HTM Amortized Cost = BHCK1771 - BHCK1754 (disclosed, not recognized)
