60-505: After the completion of planning, the project was written out as a build–lease–transfer (BLT) project, and Daewoo was selected as preferred bidder in September 2008. Construction was scheduled to last from October 2009 to March 2013. Due to the global financial crisis , it was difficult to gather investors to finance the project, and negotiations stalled. An agreement was finally signed on December 21, 2010, with construction set to start in

120-402: A BOT project the project company or operator generally obtains its revenues through a fee charged to the utility/ government rather than tariffs charged to consumers. A number of projects are called concessions, such as toll road projects, which are new build and have a number of similarities to BOTs. In general, a project is financially viable for the private entity if the revenues generated by

180-569: A few US states ( California , Florida , Indiana , Texas , and Virginia ). However, in some countries, such as Canada , Australia , New Zealand and Nepal , the term used is build–own–operate–transfer (BOOT). The first BOT was for the China Hotel , built in 1979 by the Hong Kong listed conglomerate Hopewell Holdings Ltd (controlled by Sir Gordon Wu ). BOT finds extensive application in infrastructure projects and public–private partnership . In

240-446: A firm's ability to manage multiple projects. For these reasons, corporations use IRR in capital budgeting to compare the profitability of a set of alternative capital projects . For example, a corporation will compare an investment in a new plant versus an extension of an existing plant based on the IRR of each project. To maximize returns , the higher a project's IRR, the more desirable it

300-421: A higher IRR than candidate capital investment projects or acquisition projects at current market prices. Funding new projects by raising new debt may also involve measuring the cost of the new debt in terms of the yield to maturity (internal rate of return). IRR is also used for private equity , from the limited partners' perspective, as a measure of the general partner's performance as investment manager. This

360-457: A higher initial investment than a second mutually exclusive project, the first project may have a lower IRR (expected return), but a higher NPV (increase in shareholders' wealth) and should thus be accepted over the second project (assuming no capital constraints). When the objective is to maximize total value, IRR should not be used to compare projects of different duration. For example, the NPV added by

420-738: A new airport in a busy metropolis. BLT stands for build-lease-transfer, in which the public sector partner leases the project from the contractor and also takes responsibility for its operation. ROT (renovate-operate-transfer) is a procurement method for infrastructure that already exists but is performing substandardly. As you know, when essential services are no longer operating efficiently or effectively, repairs can be costly. When an obsolete facility or amenity (any public service such as telephone lines, etc.) becomes outdated and requires expensive repairs, it can be financed through public-private partnerships between public entities and private contractors that are able to provide renovation services and operate

480-618: A northern semicircle around Seoul, complementing the southern semicircle formed by the Suin–Bundang Line . Another part of the tentative 2010 plans was a southern extension from Wonsi, connecting up with the Janghang Line before Hongseong station. As of April 2023, the construction of this section was 92% completed and expected to be opened in the second half of 31 October 2024. [REDACTED] The section from Sosa to Wonsi opened on June 16, 2018. The first phase (Sosa to Daegok) of

540-415: A profit from your project. While you manage your contract, you generate profit by charging fees from the users of your project, and you have the project as an asset. While the risk is yours, this risk is offset by various government incentives, funding, tax breaks, money to hire select people (such as unemployment job initiatives), and any other benefits that the regulatory body sees fit to grant you. At

600-414: A tool applied to making an investment decision on whether a project adds value or not, comparing the IRR of a single project with the required rate of return, in isolation from any other projects, is equivalent to the NPV method. If the appropriate IRR (if such can be found correctly) is greater than the required rate of return, using the required rate of return to discount cash flows to their present value,

660-573: A whole number. The cash flow should still be discounted by a factor 1 ( 1 + r ) t n {\displaystyle {\frac {1}{(1+r)^{t_{n}}}}} . And the formula is For numerical solution we can use Newton's method where NPV ′ {\displaystyle \operatorname {NPV} '} is the derivative of NPV {\displaystyle \operatorname {NPV} } and given by An initial value r 1 {\displaystyle r_{1}} can be given by As

720-402: Is also known as design-build. Modified versions of the "turnkey" procurement and BOT "build-operate-transfer" models exist for different types of public-private partnership (PPP) projects, in which the main contractor is appointed to design and construct the works. This contrasts with the traditional procurement route (the build-design model), where the client first appoints consultants to design

780-494: Is because it is the general partner who controls the cash flows, including the limited partners' draw-downs of committed capital . Given a collection of pairs ( time , cash flow ) representing a project, the NPV is a function of the rate of return . The internal rate of return is a rate for which this function is zero, i.e. the internal rate of return is a solution to the equation NPV = 0 (assuming no arbitrage conditions exist). Given

840-421: Is deposited once, interest on this deposit is paid to the investor at a specified interest rate every time period, and the original deposit neither increases nor decreases, would have an IRR equal to the specified interest rate. An investment which has the same total returns as the preceding investment, but delays returns for one or more time periods, would have a lower IRR. In the context of savings and loans,

900-499: Is different from the BOT (build-operate-transfer) delivery model, in which the private party does not own the project as an asset; they only receive a concession to operate it for a period of time. The BOOT delivery model is different from classical PPP (public-private partnerships) models which refer to project agreements where a private entity takes over the building and operation of government-owned infrastructure. Build-own-operate-transfer

960-400: Is given by r {\displaystyle r} in: This rational polynomial can be converted to an ordinary polynomial having the same roots by substituting g (gain) for 1 + r {\displaystyle 1+r} and multiplying by g N {\displaystyle g^{N}} to yield the equivalent but simpler condition The possible IRR's are

1020-485: Is greater than a minimum acceptable rate of return . If the estimated IRR of a project or investment - for example, the construction of a new factory - exceeds the firm's cost of capital invested in that project, the investment is profitable. If the estimated IRR is less than the cost of capital, the proposed project should not be undertaken. The selection of investments may be subject to budget constraints. There may be mutually exclusive competing projects, or limits on

1080-588: Is most accurate when 0 > NPV n > NPV n − 1 {\displaystyle 0>\operatorname {NPV} _{n}>\operatorname {NPV} _{n-1}} ) has been shown to be almost 10 times more accurate than the secant formula for a wide range of interest rates and initial guesses. For example, using the stream of payments {−4000, 1200, 1410, 1875, 1050} and initial guesses r 1 = 0.25 {\displaystyle r_{1}=0.25} and r 2 = 0.2 {\displaystyle r_{2}=0.2}

1140-471: Is often the best kind of delivery model, in which a private sector party, or consortium, receives a mandate from a private or public sector client to finance, design, construct, own, and operate a long-term project. If you have been awarded a BOOT contract, this means that during that time period, you, the private party or your consortium, own and operate the facility. Your goal is to recover the costs of your investment, operations, and maintenance, and also make

1200-436: Is the "annualized effective compounded return rate" or rate of return that sets the net present value (NPV) of all cash flows (both positive and negative) from the investment equal to zero. Equivalently, it is the interest rate at which the net present value of the future cash flows is equal to the initial investment, and it is also the interest rate at which the total present value of costs (negative cash flows) equals

1260-491: Is the case where the stream of payments consists of a single outflow, followed by multiple inflows occurring at equal periods. In the above notation, this corresponds to: In this case the NPV of the payment stream is a convex , strictly decreasing function of interest rate. There is always a single unique solution for IRR. Given two estimates r 1 {\displaystyle r_{1}} and r 2 {\displaystyle r_{2}} for IRR,

1320-467: Is the cash value of the project at the end, equivalently the cash withdrawn if the project were to be liquidated and paid out so as to reduce the value of the project to zero. In the second condition C 0 {\displaystyle C_{0}} is the leading coefficient of the ordinary polynomial in g while C N {\displaystyle C_{N}} is the constant term. The period n {\displaystyle n}

1380-482: Is to undertake the project. There are at least two different ways to measure the IRR for an investment: the project IRR and the equity IRR. The project IRR assumes that the cash flows directly benefit the project, whereas equity IRR considers the returns for the shareholders of the company after the debt has been serviced. Even though IRR is one of the most popular metrics used to test the viability of an investment and compare returns of alternative projects, looking at

1440-415: Is usually given in years, but the calculation may be made simpler if r {\displaystyle r} is calculated using the period in which the majority of the problem is defined (e.g., using months if most of the cash flows occur at monthly intervals) and converted to a yearly period thereafter. Any fixed time can be used in place of the present (e.g., the end of one interval of an annuity );

1500-400: The cost of capital , or financial risk . The method may be applied either ex-post or ex-ante . Applied ex-ante, the IRR is an estimate of a future annual rate of return. Applied ex-post, it measures the actual achieved investment return of a historical investment. It is also called the discounted cash flow rate of return (DCFROR) or yield rate. The IRR of an investment or project

1560-628: The secant method , r {\displaystyle r} is given by where r n {\displaystyle r_{n}} is considered the n {\displaystyle n} approximation of the IRR. This r {\displaystyle r} can be found to an arbitrary degree of accuracy . Different accounting packages may provide functions for different accuracy levels. For example, Microsoft Excel and Google Sheets have built-in functions to calculate IRR for both fixed and variable time-intervals; "=IRR(...)" and "=XIRR(...)". The convergence behaviour of by

1620-457: The (period, cash flow) pairs ( n {\displaystyle n} , C n {\displaystyle C_{n}} ) where n {\displaystyle n} is a non-negative integer, the total number of periods N {\displaystyle N} , and the NPV {\displaystyle \operatorname {NPV} } , ( net present value ); the internal rate of return

1680-458: The BOT framework a third party, for example the public administration, delegates to a private sector entity to design and build infrastructure and to operate and maintain these facilities for a certain period. During this period, the private party has the responsibility to raise the finance for the project and is entitled to retain all revenues generated by the project and is the owner of the regarded facilities. The facility will be then transferred to

1740-453: The IRR in isolation might not be the best approach for an investment decision. Certain assumptions made during IRR calculations are not always applicable to the investment. In particular, IRR assumes that the project will have either no interim cash flows or the interim cash flows are reinvested into the project which is not always the case. This discrepancy leads to overestimation of the rate of return which might be an incorrect representation of

1800-417: The IRR is also called the effective interest rate . The IRR is an indicator of the profitability , efficiency, quality, or yield of an investment. This is in contrast with the NPV , which is an indicator of the net value or magnitude added by making an investment. To maximize the value of a business, an investment should be made only if its profitability, as measured by the internal rate of return,

1860-410: The NPV of that project will be positive, and vice versa. However, using IRR to sort projects in order of preference does not result in the same order as using NPV. One possible investment objective is to maximize the total NPV of projects. When the objective is to maximize total value, the calculated IRR should not be used to choose between mutually exclusive projects. In cases where one project has

1920-427: The NPV of the inflows only (that is, set C 0 = 0 {\displaystyle \mathrm {C} _{0}=0} and compute NPV). A cash flow C n {\displaystyle C_{n}} may occur at any time t n {\displaystyle t_{n}} years after the beginning of the project. t n {\displaystyle t_{n}} may not be

1980-470: The Sosa to Ilsan extension opened on July 1, 2023. The second phase (Daegok to Ilsan) of the Sosa to Ilsan extension opened on August 26, 2023. The line currently utilizes seven four-car Class 391000 trains manufactured by Hyundai Rotem and ten four-car Class 391000 trains manufactured by Dawonsys . The line is being extended southward from Wonsi to Seohwaseongnamyang. Station names may be subject to change as

2040-484: The arrangement, the fees are usually raised during the concession period. The rate of increase is often tied to a combination of internal and external variables, allowing the proponent to reach a satisfactory internal rate of return for its investment. Countries where BOT is prevalent are Thailand , Turkey , Taiwan , Bahrain , Pakistan , Saudi Arabia , Israel , India , Iran , Croatia , Japan , China , Vietnam , Malaysia , Philippines , Egypt , Myanmar and

2100-409: The design and construction of the work to the employer’s requirements, the contractor is also responsible for operating and maintaining the completed facility. The operation and maintenance period will span decades, during which time the contractor is said to have the "concession," is responsible for the operation of the facility, and benefits from operational income. The facility itself, however, remains

2160-437: The development and then a contractor to construct the work. The private contractor designs and builds a facility for a fixed fee, rate, or total cost, which is one of the key criteria in selecting the winning bid. The contractor assumes the risks involved in the design and construction phases. Turnkey procurement under a design-build contract means that the design-build team would serve as the owner’s representative to determine

2220-428: The end of the contractual period (typically in the order of decades), ownership of the construction is given back to the state (or federal actor). You may receive a fee for this transfer. The scale of investment by the private sector and type of arrangement means there is typically no strong incentive for early completion of a project or to deliver a product at a reasonable price. This type of private sector participation

2280-481: The expertise and efficiency that the private entity is expected to bring as well as the risk transfer . Therefore, the private entity bears a substantial part of the risk. These are some types of the most common risks involved: The BOOT procurement strategy utilizes project finance to fund large-scale greenfield infrastructure projects such as local power stations, water treatment facilities and sewage facilities, or transit infrastructure, etc. The BOOT delivery model

Project costs are 1.5248 trillion South Korean won , the contractor has altogether seven years for design and construction, and will manage and maintain the line for the first 20 years of operation. The first section began construction in 2011 and opened on June 16, 2018. The second section runs north from Sosa to Daegok on the Gyeongui-Jungang Line and Seoul Subway Line 3 . There are transfers to several other lines. It

Internal rate of return Internal rate of return ( IRR ) is a method of calculating an investment 's rate of return . The term internal refers to the fact that the calculation excludes external factors, such as the risk-free rate , inflation ,

Tentative plans foresee the upgrade and incorporation of the Gyooe Line , a single-track non-electrified line without passenger service that connects Neunggok station (with a junction just before Daegok station) and Uijeongbu station in Uijeongbu . The Uijeongbu–Daegok–Sosa–Wonsi Line would then provide orbital metro service as

The private entity will have the right to operate it for a set period of time. This enables the project proponent to recover its investment and operating and maintenance expenses in the project. BOT is usually a model used in public–private partnerships . Due to the long-term nature of

2700-543: The project are combined under one private contractor. Hart (2003) argues that under bundling incentives to make cost-reducing investments are larger than under unbundling. However, sometimes the incentives to make cost-reducing investments may be excessive because they lead to overly large reductions of quality, so it depends on the details of the project whether bundling or unbundling is optimal. Hart's (2003) work has been extended in many directions. For example, Bennett and Iossa (2006) and Martimort and Pouyet (2008) investigate

2760-415: The project cover its cost and provide sufficient return on investment . On the other hand, the viability of the project for the host government depends on its efficiency in comparison with the economics of financing the project with public funds. Even if the host government could borrow money on better conditions than a private company could, other factors could offset this particular advantage. For example,

2820-420: The project management after the repairs have been completed. In contract theory , several authors have studied the pros and cons of bundling the building and operating stages of infrastructure projects. In particular, Oliver Hart (2003) has used the incomplete contracting approach in order to investigate whether incentives to make non-contractible investments are smaller or larger when the different stages of

2880-413: The project, while the client finances the project and retains ownership. DBFO stands for design-build-finance-operate, which also assigns the responsibility to the private organization to design, build, finance, and operate. Financing your competitive project may be easy when there is a high demand for a service right now, and investors will throw money at any project that claims the spoils, such as opening

2940-438: The property of the employer. A DBO(design-build-operate) contract is a project delivery model in which a single contractor is appointed to design and build a project and then to operate it for a period of time. The common form of such a contract is a PPP (public-private partnership), in which a public client (e.g., a government or public agency) enters into a contract with a private contractor to design, build, and then operate

3000-405: The public administration at the end of the concession agreement , without any remuneration of the private entity involved. Some or even all of the following different parties could be involved in any BOT project: A BOT project is typically used to develop a discrete asset rather than a whole network and is generally entirely new or greenfield in nature (although refurbishment may be involved). In

3060-439: The rate of return attained when the NPV of the project reaches a neutral state, precisely at the point where NPV breaks even. IRR accounts for the time preference of money and investments. A given return on investment received at a given time is worth more than the same return received at a later time, so the latter would yield a lower IRR than the former, if all other factors are equal. A fixed income investment in which money

Note that in both formulas, C 0 {\displaystyle C_{0}} is the negation of the initial investment at the start of the project while C N {\displaystyle C_{N}}

3180-511: The secant formula with correction gives an IRR estimate of 14.2% (0.7% error) as compared to IRR = 13.2% (7% error) from the secant method. If applied iteratively, either the secant method or the improved formula always converges to the correct solution. Both the secant method and the improved formula rely on initial guesses for IRR. The following initial guesses may be used: where Here, NPV 1 , i n {\displaystyle \operatorname {NPV} _{1,in}} refers to

3240-445: The secant method equation (see above) with n = 2 {\displaystyle n=2} always produces an improved estimate r 3 {\displaystyle r_{3}} . This is sometimes referred to as the Hit and Trial (or Trial and Error) method. More accurate interpolation formulas can also be obtained: for instance the secant formula with correction (which

3300-518: The sequence of cash flows then the IRR r {\displaystyle r} is given by In this case, the answer is 5.96% (in the calculation, that is, r = .0596). Since the above is a manifestation of the general problem of finding the roots of the equation NPV ⁡ ( r ) = 0 {\displaystyle \operatorname {NPV} (r)=0} , there are many numerical methods that can be used to estimate r {\displaystyle r} . For example, using

In addition to being responsible for

3420-433: The total present value of the benefits (positive cash flows). IRR represents the return on investment achieved when a project reaches its breakeven point, meaning that the project is only marginally justified as valuable. When NPV demonstrates a positive value, it indicates that the project is expected to generate value. Conversely, if NPV shows a negative value, the project is expected to lose value. In essence, IRR signifies

3480-451: The value obtained is zero if and only if the NPV is zero. In the case that the cash flows are random variables , such as in the case of a life annuity , the expected values are put into the above formula. Often, the value of r {\displaystyle r} that satisfies the above equation cannot be found analytically . In this case, numerical methods or graphical methods must be used. If an investment may be given by

3540-454: The value of the project. IRR is used to evaluate investments in fixed income securities, using metrics such as the yield to maturity and yield to call . Both IRR and net present value can be applied to liabilities as well as investments. For a liability, a lower IRR is preferable to a higher one. Corporations use IRR to evaluate share issues and stock buyback programs. A share repurchase proceeds if returning capital to shareholders has
