Comparisons

Refinery vs. Petrochemical Financial Models

Refinery and petrochemical financial models both sit in the downstream segment but are built around different core processes and margin drivers. A refinery model centres on crude distillation and conversion units producing fuels, sized by complexity and crude slate flexibility, while a petrochemical model centres on the steam cracker converting ethane or naphtha feedstock into base petrochemicals and polymers. This comparison sets out the differences and the internal transfer pricing discipline required where the two are integrated.

Sculpted vs. Bullet Debt Repayment

Sculpted and bullet repayment are two structurally different approaches to repaying project finance debt. A sculpted repayment profile derives the periodic principal repayment from the project's projected cash flows, sizing each payment to maintain a defined minimum DSCR throughout the loan life. A bullet repayment structure defers some or all principal to a single payment at maturity, funded either by the project's accumulated cash, a scheduled asset sale, or, most commonly in project finance, a refinancing. The two are not mutually exclusive: many project finance facilities combine scheduled amortisation, sculpted or otherwise, with a bullet or balloon payment for the residual balance at maturity.

Specialist Financial Model Audit vs General Advisory Review

Financial model audit can be obtained from a specialist provider, a firm or platform for which model audit is the core discipline, or from a general advisory practice, where model review sits alongside a much broader range of services such as transaction advisory, tax, and assurance. Both are legitimate options. This page compares them on methodology depth, dedicated focus, turnaround, and cost structure, without asserting either is categorically superior. The right choice depends on the transaction, the counterparty's requirements, and what else the organisation needs from the same relationship. *This page was scoped as a category level comparison rather than a named vendor comparison. Early in FMAE's market presence, a direct branded comparison against any specific large advisory firm would rest on limited published evidence. This page will be revisited for a named comparison once FMAE has published independent research, case studies, and customer evidence to support one.*

Spreadsheet Review vs Model Audit

"Spreadsheet review" is one of the loosest, least defined terms in this field. It can mean anything from a five minute visual check to something close to a full audit, and that ambiguity causes real scope confusion when it appears in an engagement letter or an internal request. This page draws a clear line between an informal spreadsheet review and a formally scoped financial model audit, so that anyone specifying either term knows exactly what they are asking for.

Standalone vs. Hybrid Renewable Models

A standalone renewable project models a single generation technology against its own dedicated interconnection capacity; a hybrid renewable project co-locates two or more technologies — most commonly generation and storage — sharing interconnection capacity and, frequently, offtake arrangements. This comparison sets out the modelling differences a builder needs to understand to represent each structure correctly, since applying standalone modelling conventions to a hybrid project overlooks interconnection and cost-allocation mechanics that only arise once technologies are co-located.

Standardized vs. IRB Approach

The standardized and internal ratings-based (IRB) approaches represent two fundamentally different methods of calculating risk-weighted assets. The standardized approach applies prescribed risk weights set by the regulatory framework; the IRB approach uses a bank's own modelled probability of default and loss given default, subject to regulatory approval. This comparison sets out the differences a modeller needs to understand when building or reviewing a bank model under either approach.

Wholesale vs. Retail Colocation Models

Wholesale and retail colocation are both colocation business models, but differ in deal size, tenant diversification, pricing granularity, and cross-connect revenue density. This comparison sets out those differences, since a model built for one can materially misstate revenue and risk if applied to a facility actually operating under the other.
