In the TBA panel, you can manually book an open (buy or short sell) and close (sell or buy to cover) trade for a to be announced (TBA) security. A TBA security is an underlying contract on a mortgage backed security to buy or sell a mortgage backed security that will be delivered at an agreed upon date in the future. The number of pools and the specific pools that will be delivered to fulfill the TBA trade are unknown at the time of the trade. You can use the Allocate TBA Buy and Allocate TBA Turnaround panels to process allocations to the underlying pools once they are known.

This article assumes you are familiar with the entity and security level elections that have been made for processing a TBA security.

Holding Term	9091	Specifies the holding term for the trade based on the number of days between the original acquisition date (tag 216) and the maturity date (tag 35) on the lot. If you use ledger reporting based on ledger granularity rules to break out accounts by holding term, the system uses this value to identify the holding term for trades related to bonds and preferred stocks. Eagle Accounting's core transaction processing calculates the holding term for you, but you can manually override the value displayed in this field. Eagle Insurance clients that use ledger granularity rules have the system calculate the holding term based on the schedule associated with a lot. Options include: Short Term. Identifies a short term holding. If the Holding Term Method field (tag 11479) in the trade's accounting basis has a value of 90 days, a short term holding term is 91 days to a year. If the Holding Term Method field has a value of 3 months, a short term holding term is 3 full months to a year. Cash Equivalent. Identifies a cash equivalent holding. If the Holding Term Method field (tag 11479) in the trade's accounting basis has a value of 90 days, a cash equivalent holding term is 90 days or less. If the Holding Term Method field has a value of 3 months, a cash equivalent holding term is 3 full months or less.

You can specify a value for reporting purposes only. Options include: Fair Value Option. Indicates the trade was previously held in a regulatory category of Fair Value Option, used for instruments managed on a fair value basis. Held for Trading. Indicates the trade was previously held in a regulatory category of Held for Trading, used for instruments held with the intent of selling them.
Pending Trade Flag	3695	Specifies whether the trade is eligible for pending trade processing prior to processing by the STAR accounting engine. If you use pending trade processing, the system can assign this value to incoming transactions that meet pending trade rule detail criteria. Or an incoming transaction can include this value. This field is hidden. Options include Y and N.
Pending Trade Status	3720	Specifies the trade's transaction status for pending trade processing prior to processing by the STAR accounting engine. If you use pending trade processing, the system can assign a value of Pending to incoming transactions that meet pending trade rule detail criteria. Or an incoming transaction can include a value of Pending or a custom pending transaction status value defined in the PEND_TRD_STATUS code category. The default status is Pending if no status is provided. This field is hidden.

Book Close Trades for TBA Securities

TBA securities are often traded in multiple lots (a single position can consist of one or more individual lots). The system requires that these positions are closed out with the identified lot selection method. That means, if there are three lots in a position, you must book three close transactions.

To manually book a close trade for a TBA security:

In Accounting Center, in the left navigation pane, click Transactions > Trades > Book Trade/Rebook Trade > Book Trade.
You see the Book Trade workspace.
Complete the options in the Search Details pane and click Search.
You see the search results based on the criteria you selected.
Select the row with the security you want to trade.
On the Book Trade tab, in the Actions group, click Action Rules, point to Close, and click Sell or Buy to Cover.
You see the Close TBA panel.
Complete the options on the Close TBA panel.
Click Submit.

Close TBA Panel Options

The following are the unique options in the Close TBA panel. See the Open TBA Panel Options section for more information about other options. Note options may vary according to your selections.

Option	Tag	Description
Accounting Information
Pairoff/Allocate Indicator	5671	Indicates whether you are allocating a TBA turnaround.
Position Original Face	109	Displays the original quantity of the position. The value must be greater than zero.
Position Current Face	122	Displays the current quantity of the position. NOTE: If the value in the Current Face field is greater than the value in this field, the value in the entity's Tech Short Eligible Flag field must be set to Yes, as specified on the Create/Edit Entity and Create Master Fund panels. If it is set to No, the trade will fail.
Lot Selection Method	27	Specifies the lot selection method the system uses to relieve (sell) lots of the security held by the entity/accounting basis. Options available in this panel include: Identified Lot (IDLOT). The specified lot or lots are sold first, which determines cost and tax implications. You can optimize this option to specific tax situations by selecting the specific lots to be sold. If you select this method, the lower pane in the panel displays lot details for each available lot, as determined by the entity's controlling basis. If no controlling basis exists, it displays lots for the primary basis. You must specify the quantity for one or more lots that you want to relieve. The total quantity you specify for the open lots must match the quantity entered for the total close. The close trade relieves the selected lots in each of the entity's accounting bases, and keeps the lot structures in sync. The system uses the lot's Orig Event ID field (tag 457) to match a single open lot in one basis to corresponding multiple open lots in another basis, as needed. This can occur for lots fractured as a result of wash sale processing. NOTE: The Identified Lot lot selection method calculates realized gain/loss on an identified cost basis, even if you set up the entity as average cost.
Prorata Noncredit Loss Reduction	16157	Indicates whether any noncredit loss associated with partial sells on the transaction is reversed prorata. This field appears only when you close less than the total outstanding quantity. Options include: Yes. Any noncredit loss associated with partial sells is reversed prorata. No. Default. Any noncredit loss associated with partial sells is reversed entirely.
