The transition shortcuts most preparers have not read

FRS 102 gives lessees a short list of practical expedients for transition. Most finance teams use none of them, because nobody has told them the list exists.

Each one is optional. Most can be taken lease by lease. Here they are:

You need not reassess whether a contract is a lease. If it was treated as a lease before, it is a lease now; if it was not, it is not (paragraph 1.45). Applied to all contracts, and you disclose that you used it.
Leases ending within 12 months of the transition date can be left off. Treat them like short-term leases and include the cost in the short-term lease expense disclosure (paragraph 1.53(c)). For a portfolio with a long tail of expiring contracts, this removes a great deal of work that would never affect a reader of the accounts.
Low-value assets need no transition adjustment (paragraph 1.52(a)). Remember that low-value is about the type of asset, not its price.
Hindsight is allowed for the lease term. If an extension option was uncertain in 2021 but you know today whether it was exercised, you may use that knowledge when deciding the term at transition (paragraph 1.53(d)).
Onerous lease provisions can stand in for an impairment review. Instead of testing every right-of-use asset for impairment on day one, you may rely on the onerous lease assessment you already made under Section 21, and adjust the asset by any provision held (paragraph 1.53(b)).
Subsidiaries of IFRS groups can bring in their IFRS 16 numbers. If you already calculate right-of-use assets and lease liabilities for a parent's consolidation, you may recognise those carrying amounts at the transition date instead of re-measuring under FRS 102 (paragraph 1.48). All leases or none, and disclosed.
A single rate across similar leases (paragraph 1.53(a)), covered in the previous piece.

One obligation comes with all of this. Paragraph 1.50 requires a description of the transitional provisions you applied. The expedients you take are a disclosure, not a private convenience, so keep a note of each decision as you make it.

In our experience the 12-month expedient is the one that saves the most time and gets raised the least.
