Portfolio Accounting We utilize a portfolio accounting system which offers a robust collection of services, including accurate reporting of principal accretion/amortization and security interest accrual and payments in conformity with Generally Accepted Accounting Principles (GAAP). It provides necessary information on the financial terms of fixed-income securities as related to principal and interest payments, coupon rates, rate resets, call dates, MBS and CMO factors, CPRs and PSAs, and maturities. We can provide a substantial selection of customizable reports, allowing easy communication and tracking of interest accrual, cash flow reconciliation, general ledger details, unrealized gain/loss, and other important data.
