Create a New Account Proration

 

Introduction

When new accounts come in partway through a period, you don't want to bill as if you managed their assets for the whole time. In this case, some firms will want to prorate the new account based on the number of days in the period, helping to reduce the impact of market changes on the account before the first invoice is issued. Other firms may prefer to treat the new account as a capital flow, and adjust accordingly.

Tamarac offers the following options for prorating new account value:

  Prorate based on ending market value Prorate based on Billing Inception Value
What Billing Method Arrears only Arrears and advance
How It Uses Flows Calculates new account prorations excluding any flows, just based on number of days. Calculates new account prorations as a capital flow.
How Adjustment Amount Is Determined

Determines the adjustment amount by applying a ratio of the number of days in the period as a proration to the fee. This is a simpler method that readily allows you to audit the total fee based on the calculations reported on the billing statement.

Determines adjustment amount based on the capital flow adjustment calculation combined with number of days. This is a more complex method that can be more difficult to audit.

Importance of Billing Inception Value Ignores the initial value of the account. Instead, it prorates a new account based on number of days the new account was in the period and the billable value at the end of the billing period.  Allows you to prorate a new account based on the value when the account was initially added to the billing group. 
Billing Inception Date You do not need to set billing inception date. You need to set billing inception date.

Prorate Fee Based on Number of Days

Prorate new accounts using number of days in period is only available when billing in arrears. It is not available when billing in advance or when using average daily or monthly balance.

When you add an account to a billing group whose billing definition prorates new accounts based only on the number of days in the billing period, you don't need to take any further action to ensure accurate proration. Tamarac identifies the new account and prorates it according to how many days elapsed in the billing period before the account was added.

When you generate a billing statement, it includes an Adjustment for New Accounts section that details the adjustment amount.

Prorating new accounts using number of days in the period:

Calculation

When you prorate new accounts based on the number of days in the period, Tamarac calculates the adjustment as:

Example: Calculate by Prorating Fee Based on Number of Days

A billing group contains two accounts: Account A and Account B. Account B is a new account that was opened 23 days into the period with a $1,500 value. At the end of the billing period, each account has an ending market value of $2,000, giving the billing group a total billable value of $4,000.

Calculating the fee using a simple number of days proration produces a total fee of $8.75, as detailed below:

Billing Group Values at the End of the Period:

Account A: $2,000

Account B: $2,000

Total Billable Value: $4,000

New Account Details:

Billing Inception Value: $1,500

Billing Inception Date: 23 days into the billing period

Fee Calculation:

  1. Calculate the gross fee.

  2. Calculate the adjustment amount.

  3. Apply the adjustment to the gross fee.

Calculate the Gross Fee

Billable value:

$4,000

Annual rate:

1% or 0.25%/quarter

Gross quarterly fee:

$4,000 × 0.25% = $10.00

Billed value for each account: $10.00 × ($2,000/$4,000) = $5.00
Calculate the Adjustment Amount

Ending market value for new account:

$2,000

Elapsed number of days in period:

23

Total number of days in period:

92

Calculate adjustment amount:

$5.00 × (23/92) = $1.25

Apply New Account Adjustment to Gross Fee

Total fee:

$10.00 - $1.25 = $8.75

When you generate a billing statement, it includes an Adjustment for New Accounts section that details the adjustment amount calculation.
