Grandfathered Accounts and a 45-Day Notice
Larkspur Analytics has published this internal notice: “Accounts opened before 1 March 2023 are grandfathered: they keep the 5 GB tier at $9 per month. A grandfathered account that exceeds 5 GB in two consecutive billing cycles will be moved to the 50 GB tier at $14 per month after a 45-day notice. The 45-day notice begins on the first day of the month following the second overage cycle.” Priya, a support agent, opens a ticket from a customer who opened an account on 12 February 2023. The account exceeded 5 GB in January and February 2024. The customer asks, “So I’ll be charged $14 in March, right?” Priya has the billing calendar, which shows charges posted on the first of each month, and a note from Finance saying “no mid-cycle proration.” She also has the customer’s usage graph, which shows March usage is already 6 GB. Priya must answer accurately without promising a refund and must decide whether the March charge is $9 or $14.
1. Determine the March charge and lay out the timeline that supports your answer.

The March charge is $9, not $14. The account opened on 12 February 2023, so it is grandfathered because that date is before 1 March 2023. It exceeded 5 GB in January and February 2024; those are two consecutive billing cycles, so the overage condition is met at the end of February. The notice begins on the first day of the month following the second overage cycle, which is 1 March 2024. Forty-five days from 1 March is 15 April 2024. The notice must run before the account is moved, so the move cannot take effect on 1 March.
Because billing posts on the first of the month and Finance does not prorate mid-cycle, the 1 March charge remains $9. The 1 April charge also remains $9 because the notice period is still running. The earliest sensible effective date under this billing system is 1 May 2024, after the notice ends on 15 April. March usage of 6 GB does not change the March charge; it may affect later cycles once the account is on the 50 GB tier.
2. What does “grandfathered” actually do in this notice, and what inference must a reader make that the word alone does not supply?
Read the worked answer
In this notice, grandfathered is a status that preserves a legacy price and allowance: the 5 GB tier at $9. It is not a promise of permanence. The word by itself does not tell a reader how long the status lasts, what triggers loss of the status, or whether the price can change. Those details come from the next two sentences: two consecutive overage cycles trigger a move, and the move happens only after a 45-day notice.
The required inference is that grandfathered is conditional. A reader who treats it as “locked forever” will misread the notice; a reader who treats it as “already moved” will also misread it. The notice’s structure is status → trigger → notice → new tier. Priya should explain the condition, not just repeat the label. She should also avoid saying the customer will “never” pay $14, because the notice clearly provides a path to that tier.
3. Draft a two-sentence reply to the customer and identify one thing Priya should not say.
Read the worked answer
A defensible reply is: “Your 1 March charge will be $9. The 45-day notice period began on 1 March and ends on 15 April, so the $14 tier will apply after that; with first-of-the-month billing and no proration, expect the change on your 1 May invoice.” This answers the question, gives the reason, and does not promise a refund.
Priya should not say “you will be charged $14 in March” or “nothing changes until May” without the billing caveat. The first is factually wrong under the notice; the second could be heard as a promise that April is also $9, which happens to be true here but is an inference from the billing calendar, not from the notice alone. She also should not tell the customer that March usage of 6 GB is irrelevant forever; it is irrelevant to the March charge, but it may matter after the tier change. If the customer asks for a refund, Priya should route the request rather than promise one.
