What auditors actually struggle with on integrated plants - read with IFRIC 20, ITFG, EAC opinions, and the SAP-AA trap nobody talks about
On paper, Ind AS 16 is a short standard. Recognise the asset, measure it, depreciate it, derecognise it. In practice , the standard does the heavy lifting in some of the most contested entries in any manufacturing or mining audit - and almost never on its own. It travels with IFRIC 20 (stripping costs in surface mining), with the ITFG (Ind AS Transition Facilitation Group) bulletins, and with the EAC (Expert Advisory Committee) opinions of the ICAI.
This piece is for the auditor capitalising a pellet plant ramp-up, the CFO who has just been told the OB-removal cost is not period cost any more, and the CA student who has read the standard but never seen a commissioning JV. It walks through the issues that show up on a live integrated-plant file - and the authoritative guidance that decides them.

1. The frame: what Ind AS 16 actually does
Ind AS 16 governs Property, Plant and Equipment (PPE). Three questions run through the standard:
- Recognition - when does a cost become part of an asset rather than a P&L charge?
- Measurement - what goes into cost on initial recognition, and what stays out?
- Depreciation - over what period, by which method, with which components?
The recognition criteria in paragraph 7 are the gate: the future economic benefits must be probable, and cost must be measurable reliably. Everything else - directly attributable costs (para 16), the test-run treatment (para 17(e)), commissioning revenue (para 20A), component accounting (paras 43–47), decommissioning (para 16(c)) - sits downstream of this gate.
Why this article exists
Most disputes I see in the field are not about whether Ind AS 16 applies. They are about which paragraph, which interpretation, and whose authoritative pronouncement closes the question - Ind AS 16 itself, IFRIC 20, an ITFG clarification, or an EAC opinion.
2. Constructing an integrated plant: where capitalisation gets hard
An integrated plant - a pellet plant feeding a steel plant, a captive power plant feeding both, a beneficiation circuit feeding the pellet line - is the textbook setting for Ind AS 16 disputes. Multiple units commission at different dates, share common facilities, and ramp up in stages. Five issues recur:
2.1 When does an asset become 'available for use'?
Paragraph 55 of Ind AS 16 is unforgiving: depreciation begins when the asset is available for use - in the location and condition necessary for it to be capable of operating in the manner intended by management. Not when commercial production starts. Not when capacity utilisation hits 80 percent.
Two practical consequences:
- Idle time after readiness is not a reason to keep capitalising costs. Once the unit is capable of operating, attributable cost capitalisation stops (para 20).
- Stabilisation losses, low-yield output during ramp-up, and operating losses after commissioning are P&L items, not part of cost (para 20).
The frequent error on field: the audited entity treats the 'CoD' or 'commercial operation date' as the trigger, when the standard's trigger is technical readiness. Plants are often ready months before the commercial declaration.
2.2 Test-run output and commissioning revenue (the para 20A question)
The 2021 amendment inserted paragraph 20A. Before this amendment, entities netted the proceeds of saleable output produced during the test run against the cost of the asset. The amendment prohibits that. Now:
- Proceeds from selling items produced while bringing the asset to its intended location and condition are recognised in P&L.
- The cost of those items is measured per Ind AS 2 and also routed to P&L.
- Only the cost of testing whether the asset is functioning properly - the technical test itself - sits in PPE.
Field translation
On a pellet plant, the very first lots of pellets produced during cold and hot commissioning used to be netted off against capital WIP. Post para 20A, that is wrong. The sale value goes to P&L. The cost of producing those pellets is inventoried and charged out. Only the genuine technical-test cost (consumables in a calibrated dry run, instrumentation set-points, refractory bake-out) stays in CWIP.
2.3 Directly attributable costs: what survives the para 16 filter
Paragraph 16 admits to PPE only costs directly attributable to bringing the asset to its location and intended condition. Paragraphs 17 and 19 then carve out a list. The practical filter I use:
The trap I see repeatedly: salaries of the project management team . The directly-attributable portion of the time of engineers, project managers, QA personnel who are exclusively or substantially on the project is capitalisable. The CFO's time signing off the project is not. Documentation of timesheets makes or breaks this line in audit.
2.4 Decommissioning, restoration, and the asset-retirement liability
Paragraph 16(c) requires the initial estimate of dismantling, removal and site restoration cost - when the entity has a present obligation - to be capitalised as part of PPE, with the corresponding liability recognised at present value under Ind AS 37. This is one of the most under-documented areas on mining and integrated steel files.
Four moving parts to test:
- Existence of a present obligation - legal (mining lease conditions, environmental clearance) or constructive (published commitments).
- Best estimate of the future cash outflow at completion - not the entity's wish, but a defensible technical estimate.
- Discount rate - pre-tax, reflecting current market assessments of the time value of money and risks specific to the liability (Ind AS 37 para 47).
- Subsequent re-measurement under Appendix A to Ind AS 16 (the equivalent of IFRIC 1) - changes in estimated cash flows, changes in discount rate, and the unwinding of the discount are accounted for distinctly.
Auditor note
Where the lease is in its terminal year - a recurring fact pattern on Indian mining files - the decommissioning provision must be tested for both completeness (have all closure activities been costed?) and timing (the cash flow is no longer a long-dated estimate; the discount has substantially unwound). The shorter the residual period, the larger the year-on-year unwinding charge.
2.5 Component accounting and major inspection costs
Paragraphs 43–47 require that each part of an item of PPE with a cost significant in relation to the total cost be depreciated separately. On an integrated plant, this is not a paperwork exercise - it is the difference between a five-year P&L charge and a thirty-year one.
Common components carved out in practice:
- Refractory lining of a kiln, BF lining, ladle linings - significantly shorter useful life than the vessel.
- Major rotating equipment in beneficiation and pelletisation - gearboxes, drives - replaced at intervals shorter than the host asset.
- Catalyst beds, filter media, screens.
- Wind turbine blades, gear assemblies and generators where these have lives distinct from the tower.
Paragraph 14 separately permits capitalisation of major inspection or overhaul costs as a replacement, provided the recognition criteria are met. The previous inspection cost (or, on first adoption, an implied portion of the asset's cost) is derecognised. This is genuinely a different model from periodic-maintenance expensing and requires the entity to identify and track inspection components from day one.
3. IFRIC 20: stripping costs in the production phase of a surface mine
IFRIC 20 - in India, Appendix B to Ind AS 16 - addresses something Ind AS 16 alone does not handle well: overburden-removal (stripping) activity in the production phase of a surface mine.
3.1 The two-benefit framework
Stripping during production gives the entity two distinct benefits:
- Ore produced today - accounted for as inventory under Ind AS 2.
- Improved access to a future identified component of the ore body - accounted for as a non-current asset under Ind AS 16, called the stripping activity asset .
All three of the following recognition tests must be met for the stripping activity asset:
- It is probable that future economic benefit (improved access to ore) will flow to the entity.
- The component of the ore body for which access has been improved can be identified.
- The costs relating to the stripping activity can be measured reliably.
3.2 Allocation between inventory and the stripping asset
Where the cost of producing the inventory and the cost of creating the stripping activity asset are not separately identifiable, the entity allocates the total stripping cost between the two using a relevant production measure. The Appendix names two acceptable bases:
- Cost of inventory produced versus expected cost (more theoretically aligned).
- Volume of waste extracted versus expected volume (more frequently used in Indian practice for ease of monitoring).
Once chosen, the basis must be applied consistently. Auditor question: is the 'expected' denominator a defensible mine plan, or an after-the-fact rationalisation?
3.3 Subsequent measurement and depreciation
The stripping activity asset is depreciated or amortised on a systematic basis over the expected useful life of the identified component of the ore body that becomes more accessible - typically the units-of-production method against the reserves of that component, not over the life of the mine as a whole.
Terminal-lease-year fact pattern
Where a mining entity is in its terminal lease year, the 'identified component' to which the stripping asset attaches is, by definition, close to fully extracted. The unamortised stripping asset balance must be tested for impairment under Ind AS 36 and any remaining carrying amount amortised aggressively over residual production. Carrying a stripping asset forward where the component is exhausted is, by definition, an over-statement.
3.4 Common errors I have seen on files
- Entire production-phase OB removal expensed as period cost - ignores Appendix B and understates assets.
- Entire production-phase OB removal capitalised - ignores the inventory portion and overstates assets.
- The 'component' is taken to be the whole mine - defeats the purpose of the standard and is technically wrong.
- Allocation ratios revised year-on-year without a documented change in mine plan.
4. ITFG bulletins: where the standard met Indian practice
The Ind AS Transition Facilitation Group of the ICAI issued bulletins through the transition years (the bulletin series began in 2016) clarifying issues that were arising in practice. These are not authoritative pronouncements - only the standards themselves are - but they reflect the considered view of an expert group and are routinely cited in working papers and reviewed by regulators.
On Ind AS 16 specifically, the recurring themes across the bulletin series are worth listing because they decide live audit issues:
a. Treatment of revenue from test runs before the 20A amendment
Pre-amendment, the ITFG view was consistent with the then-text of Ind AS 16: deduct test-run sale proceeds from the cost of bringing the asset to its intended condition, to the extent of cost of testing. Beyond that point, recognise in P&L. The 2021 amendment overtook this position. Working papers must clearly mark which side of the amendment date the transaction falls on.
b. Deemed cost election on first-time adoption (Ind AS 101)
Several bulletins clarified the interaction of the Ind AS 101 deemed-cost option with Ind AS 16 - particularly that the election applies on an asset-by-asset basis only where permitted, that previous GAAP carrying value can be used as deemed cost at the date of transition, and that the election once made is irrevocable. On any audit picking up an entity that transitioned to Ind AS, the working papers should evidence the basis of measurement carried forward.
c. Spare parts: PPE or inventory?
The 2014 amendment to AS 10 and the Ind AS 16 text together changed the historic 'spares > 1 year = capitalised' rule. Now the test is whether the item meets the definition of PPE - held for use in production, expected to be used during more than one period. ITFG clarifications underscore that:
- Major spare parts and stand-by equipment qualify as PPE when they meet the definition; otherwise they are inventory.
- A spare that can be used only in connection with a specific item of PPE is depreciated over a period not exceeding the useful life of the principal asset.
- The capitalisation threshold ('insurance spares') from old AS 10 does not survive - the recognition criteria in Ind AS 16 govern.
d. Componentisation and the threshold question
ITFG has consistently refused to prescribe a percentage threshold for 'significant' components. The judgment is entity-specific and asset-specific. Working papers should evidence the basis - typical approaches include carving out components above a stated percentage of total asset cost, or above an absolute rupee threshold, or by reference to engineering judgment on differing useful lives, but the rationale must be documented.
e. Capitalisation cut-off - readiness vs. commercial declaration
ITFG bulletins have repeatedly reinforced that capitalisation ceases when the asset is in the location and condition necessary for it to be capable of operating in the manner intended by management. The Board's later declaration of commercial operations is not the trigger. Where the two dates diverge materially, the entity must justify the gap.
Reading the ITFG correctly
ITFG bulletins are clarifications, not standards. They cannot be relied on to override the text of Ind AS 16. Where a bulletin and a later amendment to the standard diverge, the standard governs. Where the bulletin and an EAC opinion diverge on the same fact pattern, both are persuasive, but the more recent and the more specific - typically EAC on a tightly defined query - tends to carry more weight in working-paper documentation.
5. EAC opinions: the case-specific Ind AS 16 jurisprudence
The Expert Advisory Committee of the ICAI issues opinions on specific queries put to it by members. These are highly fact-bound. They are also the closest thing Indian practice has to a case-law tradition on Ind AS - read together, they map how the principles in the standards have been applied to particular Indian fact patterns.
Without listing specific opinions (which are case-specific and dated), the patterns that have repeatedly come through EAC reasoning on Ind AS 16 are worth knowing:
Pattern 1 - Pre-operative expenses are not a residual capitalisation bucket
Where a company sought to capitalise broad 'pre-operative expenses' that had accumulated during a long gestation, the EAC has consistently held that only directly attributable costs satisfying paragraph 16 may be capitalised. Administrative overheads, general financing costs not capitalisable under Ind AS 23, and costs of activities not necessary to bring the asset to its location and intended condition cannot be parked in CWIP and capitalised on commissioning.
Pattern 2 - Trial-run and stabilisation
EAC opinions on trial-run treatment, both pre and post the para 20A amendment, have emphasised three distinctions: (i) what is a genuine technical test versus saleable output; (ii) what is bringing the asset to readiness versus normal operation at sub-optimal yield; (iii) what is part of the cost of the asset versus an operating loss. The standard's text does the work, but the EAC has applied it to specific industries - cement, chemicals, steel.
Pattern 3 - Subsequent expenditure: replacement vs. day-to-day servicing
Paragraph 12 of Ind AS 16 excludes day-to-day servicing from PPE. Paragraph 13 capitalises replacements where the recognition criteria are met and derecognises the previous part. EAC opinions on major repairs and overhauls have applied this distinction - for example, distinguishing a recurring annual shutdown maintenance from a major life-extending overhaul that meets para 13.
Pattern 4 - Foreign exchange differences
EAC opinions have addressed the interaction of Ind AS 16 with Ind AS 21 on foreign exchange differences arising on long-term foreign currency monetary items (the para D13AA carve-out under Ind AS 101 for first-time adopters, and the general Ind AS 21 position thereafter). The principle: forex differences are generally a finance item, not a directly attributable cost under Ind AS 16, unless they qualify as a borrowing cost adjustment under Ind AS 23.
Pattern 5 - Depreciation method and useful life
On depreciation method, EAC opinions have consistently endorsed the principle in paragraph 60 - the method must reflect the pattern of consumption of the asset's future economic benefits. Where the entity has used a method (e.g., straight-line) that does not reflect the consumption pattern (e.g., on a mine with a clearly front-loaded extraction profile), the EAC has held that the method must be re-assessed.
6. The SAP-AA trap: additions posted to an existing asset code
This is the section that earns the article. It is an issue I see on every large SAP file and almost never see written about. Most ERP systems, and SAP FI-AA in particular , do not by default treat a current-year addition posted to an existing asset master as a new component with its own depreciation start. They inherit the depreciation key, useful life, and capitalisation start date of the parent asset master. The new ₹3.5 crore addition begins depreciating as if it had been incurred on the parent's original capitalisation date - sometimes a decade earlier.
6.1 Why this happens
Three SAP-AA design choices combine:
- Same asset master = same depreciation key. When an acquisition transaction is posted to an existing asset number, SAP applies the depreciation key already attached to that asset - including its capitalisation date and useful life.
- Period-control rules. The 'period control' setting in the depreciation key determines from which day depreciation on the new acquisition value starts. The default in many Indian configurations back-dates the start to the parent's original capitalisation date rather than to the actual posting date of the addition.
- No automatic sub-numbering. SAP allows sub-asset numbering (e.g., asset 2600010-1, 2600010-2) so that each addition can have its own life and start date. But the configuration is permissive, not mandatory. If the entity does not enforce sub-numbering, additions pile onto the parent.
6.2 What it looks like on the FAR
The signature is unmistakable once you know to look for it. Pull the fixed asset register and run this filter: current-year acquisition value as a percentage of opening APC. Anything above 20% is a candidate; anything above 100% is almost certainly the issue.
When an Machine master with an opening cost of ₹20,938 receives a ₹1.10 crore addition in the year, that addition is not a 'painting' - it is plainly a new asset miscoded to the existing master. The system will now depreciate the ₹1.10 crore as if it were acquired with the original parent, which on a Schedule II useful life of (say) 15 years and the parent already 8 years old, means: the new addition is fully-depreciated to its salvage value in 7 years, not 15 , and a large catch-up depreciation hits the year of addition.
6.3 Where Ind AS 16 stands
The standard is unambiguous on this point. Three paragraphs decide it:
- Paragraph 13. When parts of an item of PPE require replacement at regular intervals, the entity recognises the cost of replacing the part as part of the carrying amount of the item, and derecognises the carrying amount of the part replaced. This is the component-replacement model. A genuine 'addition' to an existing asset, where the old part is not derecognised, raises a separate question - but in either case, the new cost is its own component.
- Paragraph 43. Each part of an item of PPE with a cost significant in relation to the total cost is depreciated separately. A ₹3.5 crore addition to an ₹8.37 lakh High Mast Tower is, by definition, the dominant component now. It cannot inherit the parent's useful life by accident.
- Paragraph 55. Depreciation begins when the asset is available for use - that is, when it is in the location and condition necessary for it to be capable of operating in the manner intended by management. For an addition, that date is the date the addition itself becomes available, not the parent's original date.
The Ind AS 16 read
The standard does not care about SAP configuration. An addition is a separate depreciable amount, with its own useful life, with its own start date for depreciation. If the system says otherwise, the system is wrong - not the standard.
6.4 The audit consequence
If left uncorrected, this issue produces three errors simultaneously:
- Depreciation overstatement in the year of addition - because SAP back-dates the depreciation start and catches up multiple years in one go. Profit is understated; accumulated depreciation is overstated.
- Depreciation understatement in subsequent years - because the asset is over-depreciated in year one and reaches its residual value early. The matching principle breaks.
- Component-accounting non-compliance - paragraph 43 is plainly breached, and the issue carries a CARO 2020 reporting implication under clause 3(i)(a) (proper records of PPE).
There is also a Tax Audit follow-through. Section 43(6) of the Income Tax Act and the block-of-assets concept operate independently of the SAP book depreciation. A mis-recorded book depreciation feeds Form 3CD Clause 18 - and the auditor reporting under Form 3CB-3CD must reconcile the two.
6.5 Working-paper procedures
The procedures I run on every SAP-driven engagement:
- Extract the full FA register with opening APC, current-year acquisitions, current-year retirements, opening accumulated depreciation, current-year depreciation, and closing balances.
- Compute current-year acquisition value as a percentage of opening APC for every line. Flag every line above 20%.
- For every flagged line, obtain the SAP 'depreciation start date' for the acquisition portion (transaction type 100 or similar). Compare to the actual GR/IR posting date of the acquisition.
- Where the dates diverge, quantify the overcharge: (days from original cap date to addition date) × daily depreciation rate on the addition value.
- Cross-reference to Ind AS 16 §43 component-accounting requirement: should the addition have been recorded as a new sub-asset or new master altogether?
- Document a journal-entry proposal: reverse excess depreciation, restate accumulated depreciation, and recommend SAP master-data remediation (sub-asset numbering policy).
- Escalate to management as a control deficiency under SA 265 - this is a process-level control failure, not a one-off.
CFO note
If you run SAP and you cannot tell me, on any given asset code, the depreciation start date that the system has used for each successive addition, you do not have a fixed-asset sub-ledger you can defend. Sub-asset numbering is a five-minute master-data fix that prevents a recurring audit observation.
Closing thought
Ind AS 16 is not a standard that rewards memorising paragraphs. It rewards reading the asset. An integrated plant is built in stages; the standard is applied in stages. The auditor who treats each commissioning unit, each stripping campaign, each major spare, each decommissioning estimate as a distinct judgment - and who triangulates the standard with IFRIC 20, the relevant ITFG bulletin, and the EAC patterns - is the one whose working papers stand up at review.
That, more than anything else, is what the standard is asking for.
