What to review and when to change the plan

Use current facts to decide whether to maintain, revise or leave the plan alone, and preserve the reason for that decision.

Update the obligation before considering a new investment.

Bring the written plan and consistent account values. Reconcile flows, missing balances and unexplained activity before using return or allocation figures.

Goal
Amount, date, currency, priority and flexibility.
Funding
Accessible reserves, income, unavoidable spending and affordable contributions.
Exposure
Current weights, underlying risks, overlap and relevant outside assets or obligations.
Terms
Verified changes to charges, investment rules or access.

Outside assets can affect capacity without becoming available rebalancing capital. A standing transfer may already be unaffordable; a higher salary need not all be free to invest.

Vanguard and the SEC place goals and available time before product choice. A funding shortfall and a benchmark gap do not identify the same problem or automatically justify another fund.

Match the response to the finding.

Filled example · 20 October 2026. Invented facts, allocation and dates; not a recommended plan or review interval. Here, the target is assumed still suitable and values correct.

Decision: keep the plan; no trade

Facts checked
Goal amount, spending date and affordable contributions unchanged. Account values and flows reconciled; no unexplained activity or changed access terms.
Allocation finding
Shares at 61%; still-suitable target 60%, accepted band 55–65%. The rule calls for adjustment only outside the band at a scheduled check.
Response and reason
No allocation adjustment: 61% is within the band. Funding and risk assumptions still fit. Keep the existing target and contribution schedule.
Record and next date
Retain today's values, reconciled flows and current plan version. No transactions or unresolved questions. Next routine review: 20 October 2027; event-based protective checks remain available between reviews.

A different finding would change the entry

Separate alternatives to the facts above, not additional events in that review.

Shares at 66%, same suitable target
Maintenance → assess cash flows and costs under the agreed rule before placing orders.
An inflexible bill moves sooner
Funding and strategy → establish money available by the new deadline; revise an unsuitable target before restoring it.
An included account is missing
Accounting → reconcile the balance before drawing allocation or return conclusions.
An unauthorised transfer → protect access now.

Verify through a trusted contact route and take protective action now, not at the next investment review.

If income stops, review cash needs and contributions promptly.

Rebalancing restores a suitable target; strategy revision changes it. Correcting records or account problems is separate work. If findings coincide, establish the suitable destination before restoring an old mix.

What fact no longer supports the old target?

Name the changed deadline, spending flexibility, tolerable risk or complexity and how the proposal addresses it. The old plan is allowed to have been mistaken.

Lower risk may reduce potential growth; simplification can change exposures and incur costs. Rewriting a target to match today’s winner hides that trade-off rather than explaining it.

Mistakes and questions requiring local help

Reassess risks you misunderstood rather than continue to avoid admitting a mistake. Conversely, changing a target just to match current holdings can conceal drift.

A country move, uncertain tax treatment or disputed access may need a professional qualified in the relevant jurisdiction. Identify the question requiring help; chapter 11 develops changes in circumstances and spending.

Keep evidence for the next review.

When a plan changes, retain dated old and new versions, their assumptions and the reason. Record completed actions and actual balances, keeping unfilled orders distinct from holdings.

Apply this separate fictional policy: one goal portfolio has a given, still-accepted 50/50 shares/bonds target. Check quarterly; shares from 45% through 55%, including both endpoints, are acceptable. Direct funded contributions to the underweight part. If that restores the band, make no additional trades; otherwise compare costs and a full reset. Strategy changes require changed constraints.

The character chose this combined policy to limit attention and small transactions while accepting interim drift. It is an exercise condition, not an optimal policy for everyone or a derivation of the target.

At review, shares are €46,000 and bonds €34,000, with €4,000 new money available only for this goal. Reserve and bills are outside the boundary. Goal, income and access are unchanged and records reconcile. All figures are nominal EUR on one date; prices stay unchanged, holdings are divisible, and FX, tax and spreads are ignored. Each purchase or sale order costs €4, paid from a separate administrative budget.

Write the current finding, the cash-first route, any additional trades under this policy, the alternative full-reset cost, and the reason and timing for the next check.

Worked policy and completed review
Completed review · separate 50/50 exercise. All values nominal EUR on one date; the administrative fee budget is outside this goal portfolio.

Policy reason: the character accepts interim drift to limit attention and small transactions. Quarterly checks with a 45–55% inclusive share band implement that choice; the band does not derive the target or claim an optimal interval.

Current holdings€46,000 shares + €34,000 bonds€80,000 total · 57.5% shares: outside the band+New external money€4,000 for this goalFunded; reserves and bills stay outside→Buy bonds€46,000 + €38,000€84,000 total · 54.7619…% shares: inside

€46,000 ÷ €84,000 = 54.7619…%. After the funded contribution, the band is restored: no additional trades under this policy. Exactly 55% would also be inside. One purchase costs €4, paid separately.

Alternative: plan a full reset

Sell shares€4,000 proceeds+New external cash€4,000→Buy bonds€8,000

Holdings become €42,000 shares / €42,000 bonds. Combining the contribution and rebalance takes two orders: €8 rather than €4. The separate fee budget leaves €84,000 invested.

Goal, income and access are unchanged; records reconcile. Keep the given target and check at the next quarterly date, earlier for verified funding, security or other material changes. Neither route predicts a superior return. The next chapter tests what happens when the obligation itself changes.

01

An earlier spending date

At a review, you decide the spending date has moved earlier and adopt a different allocation target. What kind of action is this?

  • A strategy revision that needs a reason and an updated plan.
  • A maintenance adjustment, because both changes involve buying and selling towards an allocation.
  • An implementation correction, with the old written target retained until the next scheduled review.
Show the explanation

Correct answer: A strategy revision that needs a reason and an updated plan.

Rebalancing restores a target still considered suitable. Changing the target because the goal changed revises the strategy. Record the new facts, the reason and the resulting funding and maintenance arrangement so a future review can assess the decision.

02

Recording a decision

After changing a plan, which record is most useful to keep?

  • The revised targets and current values, replacing the earlier plan to keep one current version.
  • The dated old and new assumptions, relevant values and brief reason for the change.
  • The revised targets and a comparison of the following month’s returns with the old mix.
Show the explanation

Correct answer: The dated old and new assumptions, relevant values and brief reason for the change.

A dated record makes it possible to see what changed and why. Deleting the earlier assumptions makes repeated or contradictory revisions harder to recognise. A short-term return alone cannot establish whether the new arrangement met the circumstances known at the review.
