Behveèn 11t July 2024 and 301Tr June 2IY25, 45 manuscTiPts were submitted from 26 countries from Europe, Asia,
Alru, North and South Arner￿. 1 S of these Manl￿ripts were rejected or con$￿tTed unsuitsble for the journal. For
the manuscripts Submitted in Ihat kn'me int￿la1, there were 100 edrtorial decisions, 35 of wh￿h indtaled acceptan¢8
(23ycondilional acceptance {12), 34 verdicts suggested major revision, 11 suggested minor revision and 18 rejecllon
including non-suitability for the Joumal. Note that more than one verdict is appl*d to each manuscript, depending on
the number of rounds of revision, and acceptance verd￿ts rèfer also to manuscripts submitted before the interval
under conslderation. The overall reie¢tion rate for the inleThal under con$Kteration was 38%1420
Lqst yearl. The
average lime from submission to first decish?n was 43.9 days139.1 last year). This lim& is cbse to the target of 81X
weeks and E the re8uIt of the colla￿rat￿e effort of the editors and the reV￿wers. There is 8ti11 a delay in the
appearance of the first prwf, bLtI CUP is working on this wnt. 351 reviewer5 were invited, of whom 116 reviewers
submitt8d rèview8, 75 declined to review. 156 revivwers were uninvited before ag￿ing, and 4 were termlnated after
agieeing.
CUrren￿Y there Is one open Sp￿￿1 issue. Th& sp￿la1 issue wll include papers that were presented lo the
Inlemats'onal Clay Conference 2025 that took place in Dublin, IreLqnd. The deadline for submission of manusc￿pts has
been set as 30 November 2025. So far 5 paperyJ have been submitted lor thts tssue arKI a￿ under review. A second
special issue has been scheduW to mafk the 10th Anniversary of the Gansu Provincial-level K8y Laboratory of Clay
Mln8ral$ In China. An announcenEnt about this special issue will b8 pubJ￿hed on the webpages of the journal by the
end of 2025. One invrted revkni paper by A. Bakdemwnn ot 81. was publlshed in March 2025.
The Editorial Board is wothng smoothly and most ofthe ￿rnberS aro devoted to their duties. Th& turnaround time for
first editorfal deei8ion is close to the time agreed in previous Edrtorial Board meets'ngs. i.e. 6 weeks. Two very frultful
and constructive in-person toafd mbngs wgre held during the per￿￿, one during the Mid-European Clay
Conference 2024 in PLzen, Czech Republic and a second on 15 July 2025 during the ICC in Dublin. In the second
meeting it was decided to invrte Marek Szczarba toioin Ihe Edrtorial Board.
The Impact factor {IFI of the journal in 2024 increased to 19 from 1.1 in 2023 This is the highest IF ever recorded for
the joumal. which is now in the second quart]￿ (Q2) journals for mineraSogy in the Ciarivate ranking. The journal is on
the right track aThJ we expect that the collecb've effort of the editon'al board, Staff and publishing team will h8lp lo
Increase the impact factor further in the coming yoars.

MINERALOGICAL SOCIETY OF THE UNITED KINGDOM AND IRELAND
NOTES TO THE FINANCIAL STATEAIENTS AT 30 JUNE 2025
Expenditur• recognition
Liabilities are recognised as expenditure as %)on as there is a legal or constructive obligation committing
the Charity to that expendiiure, it is probable that settiement will be required and the amount of the
obligation can be measured reliably. Any expected loss from a future conference or meeting is provided
for as a liability.
All expenditure is accounted for on an accruals basis. All expenses including support cost and
governance cost are allocated or apportioned to the applicable expenditure headings.
Allocatlon of support and governance costs
Govemance costs comprise all costs Invo￿1ng the public accountability of the charity and its compliance
with regulatson and good practice. These costs indude costs related to statutory audrt and18gal fees
together with an apportionmenl of overhead and support costs as analysed in notes 6 and 7.
Foralgn currnnclos
Monetary assets and liabilrties in foreign ojrrencies are translated into 8terling at the rates of exchange
ruling at the balance sheel date. Transactions in fO￿￿n currencies are translated into 8terling at the rate
of exchange ruling at the date of the transaction. Exchange drfferences are taken into account in arrlving
at the increase or decrease in funds.
Tanglblo Flx•d A88ets ft>r use by tho Charlty and Deprnclallon
Tangible f￿ed assets are stated at cost less accumulated depreciation other than freehold land and
buildings which are stated at valuation. Depreciation is provided on tangible fixed assets at rate8
calculated to wrtte off the cost, less the estimated r8sidual value of ea¢h asset over its e8timated1rf8
Using the Stra￿ht line method at annual rates as follow8.'. Offica Fumitur8 and Equipment 25%.
Computers 33.33%.
The Charity has adopted a revaluation policy in respect of the freehold land and buildings that will be
revalued every five years. The fair value of land and buildings 18 detemiined from market based evidence
by appraisal undertaken by a professionally qualrfied valuer.
Revaluation gains and losse8 are recognised in the Statement of Financial Activities.
Stock
There are stocks of publication$, being surplus copies printed bul not sold in the year. No value ha8
been placed on stock8 of the3e publications in these financial statements.
Flx•d asset InV￿lments
Inve8tm8nts are a form of basic financral instrument and are initially recognised at their transaction
valu8 and subsequently measured at their fair value as at the balance sheet date using the dosing
