The document discusses investment accounts and related journal entries. It explains that an investment account is maintained for each security/script to record transactions separately. It also discusses entries for purchase and sale of investments at interest dates and before interest dates. For purchases/sales before an interest date, it explains the treatment for cum-interest and ex-interest quotations. Cum-interest means the quoted price includes accrued interest, while ex-interest means it does not. The accounting entries record the purchase/sale price and treat accrued interest separately.
