Time-weighted rate of return meaning

What does Time-weighted rate of return mean?
In legal practice, the time-weighted rate of return (TWR) describes a method of measuring investment performance that removes the effect of client cash inflows and outflows, so results reflect the investment manager’s decisions rather than the timing of contributions or withdrawals. It is not defined in UK or Irish legislation or case law; it is a descriptive financial term used across investment management, pensions, charities and private client matters. TWR is calculated by splitting the measurement period into sub‑periods between external cash flows, computing each sub‑period return, and geometrically linking the results. This makes it suitable for comparing portfolio performance across managers and against market indices and benchmarks. It is commonly specified in investment management agreements, side letters and trustee reporting for fair performance reporting and, where relevant, performance fee calculations, and is often referenced in expert evidence in professional negligence or valuation disputes. Firms may adopt industry standards such as the Global Investment Performance Standards (GIPS) to govern calculation and disclosure. Usage and meaning are broadly consistent across England and Wales, Scotland, Northern Ireland and Ireland. TWR is typically contrasted with the money‑weighted rate of return (MWRR/IRR), which incorporates the size and timing of cash flows and is often used for...

Key November 2024 UK banking and finance judgments: novation rectification, on-demand bonds, administrators’ duties, guarantees, misdelivery time bars, misrepresentation, assignments, immovables rule, derivatives, sanctions/administration

Banking & Finance—November 2024 case round-up Sata Internacional-Azores Airlines SA v Hi Fly Ltd and another company [2024] EWHC 2762 (Comm) Aviation finance—unpaid rent—novation of lease—rectification of novation agreement The claimant, SATA Internacional-Azores Airline SA (SATA), leased an aircraft from the defendant, Hi Fly Ltd (Hi Fly). By 2019, SATA was experiencing financial difficulties and, following negotiations, Hi Fly sold the aircraft to a third party, AELF, with the lease simultaneously novated so that AELF became the lessor. AELF and SATA then agreed to terminate the lease early, providing for re-delivery on an ‘as is where is’ basis in return for a lump sum termination payment. When these arrangements were put in place, SATA owed Hi Fly just under US$3m comprising unpaid rent, maintenance reserve payments and default interest. Of that total, a little under US$1m related to amounts outstanding from before 1 September 2019, and it was accepted that SATA remained liable to Hi Fly for that portion. There was, however, a dispute concerning the remainder...

BVCA-standard IRR in private equity: calculation, use, criticisms, modified IRR and NPV

Internal rate of return (IRR) Internal rate of return (IRR) is the benchmark financial metric set by the British Private Equity & Venture Capital Association (BVCA) for judging private equity outcomes and making comparisons across investments. IRR seeks to identify the break-even rate for an investment while recognising the time value of money, and is typically described as the discount rate that, when applied to a sequence of projected cashflows from a specific investment, results in the net present value of anticipated cash inflows (eg investments or loans to an investee company) being equal to the net present value of anticipated cash outflows (eg dividends or interest from the investee company or exit proceeds)... The formula 0 = P0 + P1/(1+IRR) + P2/(1+IRR)^2 + P3/(1+IRR)^3 + ... + Pn/(1+IRR)^n, where P0, P1, ... Pn represent the cashflows in periods 1, 2, ... n, respectively...

UK corporation tax: disguised interest in the loan relationships regime—scope, 'economically equivalent to interest' test, exclusions, split returns and elections

A 'loan relationship' means a monetary debt arising from the lending of money. Yet this wording does not capture every form of arrangement or transaction that is taxed under the loan relationships regime. The regime’s scope is specifically and expressly extended to include certain other arrangements and transactions that are treated as equivalent to debt finance. These, often labelled 'deemed loan relationships', cover arrangements which, though not meeting the strict definition of a 'loan relationship', generate a return that is economically the same as interest (sometimes described as an interest‑like return, i.e. an interest-like return). For further detail on the meaning of loan relationship and the various types of 'deemed loan relationships' within the scope of the loan relationships taxing regime, see Practice Note: Loan relationships—what are they? For the computation rules governing how profits and losses on loan relationships are calculated, recognised and brought into account for corporation tax purposes, see Practice Note: Loan relationships—the main tax rules.

CJRS post-furlough holiday pay: normal vs no normal working hours

Coronavirus (COVID-19)—holiday and holiday pay [Archived] If you require general guidance on matters concerning the right to holiday and holiday pay during the Coronavirus (COVID-19) pandemic, consult Practice Note: Coronavirus (COVID-19)—holiday and holiday pay [Archived]. The way holiday pay is calculated under the Working Time Regulations 1998 (WTR 1998), SI 1998/1833, has continued unchanged throughout the coronavirus pandemic; the amendments contained in the Employment Rights Act 1996 (Coronavirus, Calculation of a Week’s Pay) Regulations 2020 (Week’s Pay Amendments Regs 2020), SI 2020/814, do not apply to the calculation of holiday pay. Under regulation 16 of the WTR 1998, SI 1998/1833, a worker taking statutory holiday is entitled to be paid at the rate of a “week’s pay” for each week of leave, with that figure determined in accordance with sections 221–224 of the Employment Rights Act 1996 (ERA 1996), subject to specified modifications. Different approaches to calculating a week’s pay are used depending on whether the worker has “normal working hours” or “no normal working hours”...
