Valve Replacement and Other Repairs (15)13.1 What to do After a Repair (15)1.IntroductionIn this Quick Set Up Guide, you will find a step-by-step procedure to set up temperature control ofrefrigerated units using EEPR (Electric Evaporator Pressure Regulator) valves and the DT-EEPR6-valve Controller (Micro Thermo part number 950-636C).The DT-EEPR (Dual Temperature) controller issupported in Alliance v. 5.2 or later.2.Refrigeration ConfigurationSet up the rack, condenser, suction groups and cir-cuits, using the Refrigeration Configuration Tool(RefSysConfig.exe). Specify an Electronic EPR as theEEPR Control Actuator for the Refrigeration Cycle. Creat-ing the rack and entering a number for its first Circuitis the minimum required to obtain the View in Alli-ance.3.Hardware Installation1.On the controller, connect the earth ground (1 or 2), the EEPR valves (3) and the network (4).2.Power up the controller (24V AC) using the connector identified as AC1-AC2 (5).–The +5V green LED (6) lights up immediately.–The “Factory” red LED (7) and “SA” (Stand Alone) green LED (8) light up if the controller has never been used.–On outputs without valves, the LED (9) blinks very briefly (drive searching for a valve.)–On outputs with a valve, the LED blinks while the valve moves during its initialization, then remains ON. It takes about 4 minutes for 6 Sporlan valves to get initialized and positioned. The valves are positioned at half their total number of steps, if the board is in Factory condition. If the board was used previously, each valve returns to where it used to be during refrigeration. Warning : overloading transformers will result in overheating and may cause a fire. A DT-EEPR controller requires 2.1 amperes when driving Sporlan valves, and 3.4 amperes for Alco valves. A100VA, 24V transformer drives only two DT-EEPR boards with Sporlan valves, for example.4. Control of EEPR ValvesAfter this section is completed, you will be able to use the Plug-In to set EEPR valves to any desired value of %Open.1. Drop a node in Alliance (10), choosing the proposed version of Refrig Dual Temp EEPR (11).2.Click on the new node’s button (12) and, in the Details Page, give it a significant name, such as LT-EEPR1 (meaning the first Low-Temperature DT-EEPR node.) 3.Go to the Commands/Status Page and click on the Install button (13). Install the node by pressing the Service Button on the board itself, or by Manual Entry (14) of its node ID (sticker on the board.)– Loading the node software takes about 2 minutes. Each valve then gets reinitialized and positioned at its Stand Alone Position (50% of the number of steps, for a board that has Factory status.)10111413121617154.Drop a plug-in (15). Just to keep things simple, identify it by the same name as the node (16).Select the Dual Temp EEPR (17).Suggestion: The Rack’s Viewis usually a convenient loca-tion (18) to drop the plug-in.185.Open the plug-in, by clicking on its button.– “Stand-Alone Mode ON ” warnings (19) appear. In Stand-Alone mode, the node positions the valves according to the best of its knowledge, then waits for further instructions.6. In the Node Configuration box, specify the ValveSeries (20-21) (ex. Sporlan CDS).192019217.Open the Valve Config page (22).– Yellow “Detected” dots (23) indicate the outputs that presently have valves connected to them. 8. Specify the valve models (24)(ex. CDS-9).– Note : CDS-16 (angle) and CDS-17 (in-line) valves are in-terchangeable, as far as control is concerned.The Start Up feature may now beused on any valves that require im-mediate positioning :9. Click on the Start Up button(25). Enter the desired valve’s %Open (percentage of open-ing) (26) and click OK.10. At the bottom left corner of the Valve Config page, select the Rack in which the DT-EEPR isinstalled (27).11. Select the refrigerant (28).– Refrigerants are managed by the EEPR systems independently of RefSysConfig. Different names may be used for the same refrigerant, such as R507 in the EEPR and its alias, AZ50, in RefSysConfig.23242233262512. Click Apply.– The “Stand-Alone” warning disappears.– The “SA” (8) and the “Factory” (7) LEDs are now both OFF (the board being configured). – The valves get Initialized and positioned one by one, which takes about 4 minutes for 6 Sporlan valves.13. Open the Process page (29).– The valves are not yet assigned (30) to any RefUnit. – The valves are in StartUp mode (31).– Valves have reached their Start Up position, the default being 50%Open.– Actual values of %Open are shown (32), that may differ slightly from the requested values, such as 19,8% instead of a requested 20%. They are at the closest available step.– Valves can be repositioned at any time by changing the Start-Up (25) value in the Valve Config page and clicking Apply.– An Internal Schedule (33) for Off Time defrost is available immediately.Overrides (34) could be used to position valves, but defrosts are not supported in Override mode. The Start Up mode (with or without Off Time defrosts) enables you to start refrigeration even be-fore RefUnits and Circuits are configured, if the need arises.5. Set Up of RefUnits1. Complete the set up of the rack in RefSysConfig, if applicable. In order to use the EEPR valves for automatic temperature control, the refrigerated units (cases, walk-ins or open areas) must be represented by a software object called “RefUnit”, that is configured by a plug-in.2. Drop a RefUnit (35) plug-in for each refrigerated unit in the MainView.293031323436 3735A RefUnit can be used to represent a single case, or a row of identical, contiguous cases. In the above figure, for example, the installer uses the same RefUnit to represent the 3 cases (assuming that they are on the same EEPR valve). He could also drop an Auxiliary RefUnit (36) to represent the case on the left hand side, and a another one (37) for the case on the right hand side.3.Set up the RefUnits in Alliance, according to the RefUnit Quick Set Up Guide.Note : it is recommended to use RefUnits for all refrigerated units, including those that are not con-trolled by an EEPR valve.38For the EEPR valve to appear (38) in the Process page of the RefUnit, it must have been declared in the Control page of the RefUnit’s plug-in.In the DT-EEPR environment, RefUnits and valves are set up inde-pendently of one another, and in any order. When a RefUnit and its valve are both configured, temperature control and monitoring is achieved by one click of the mouse. This association is done in the DT-EEPR plug-in, as described below.6.EEPR Control of RefUnits1.Open the DT-EEPR plug-in at the Valve Config page.2.Select the Primary RefUnit (39) served by each EEPR valve.3.At the bottom of the Valve Config page, click in one of the two yel-low boxes (40) to confirm the default value of the suction pressureset point.The value suggested by the plug-in comes from the set point in the SPC. If it is not available, or if you wish to use a different value, simply enter the pressure or its equivalent saturated temperature.A DT-EEPR node supports two Suction Groups. If the RefUnits are not all on the same Suction Group, you will be asked to confirm (or provide) two suction pressure set points.–Any Dual Use or Clean switch defined in the RefUnits appears in the Available Features (41) panel. 394041There may be more than one control temperature sensor, associated with an EEPR valve. This usual-ly happens :• when a RefUnit includes more than one evaporator, each evaporator hav-ing its own temperature sensor. This is illustrated as Sys20 on Page 7, where one RefUnit includes three 5-door cases,• or when the EEPR valve controls Auxiliary RefUnits in addition to its Primary RefUnit, as illustrated above with Sys20a-b-c.In the figure on top of this page, Sys20b is the Primary RefUnit, Sys20a and Sys20c are auxiliary units. Each has its own temperature sensor that must con-tribute to the control.When you pick a Primary RefUnit that is linked to more than one control tem-perature sensor, the RefUnitDetails button (42) in the DT-EEPR Plug-In turns yellow, indicating that some input is required on your part.4. Click on the RefUnitDetails button (42).5. Select any availablecalculation block (43). 6. Set the operator (44)to Average, for low temperature applica-tions, and to Mini-mum for medium temperature applica-tions.Sys20a Sys20b Sys20c4243447. DefrostsDefrost parameters are accessed through the Valve Config Page, that has one button (45) for de-frosts controlled by a Circuit, and another button (46) for Internal Defrosts.In a typical supermarket, most defrosts are controlled by a Circuit of an MT-CKT node, and are done with the EEPR valve closed. In that case, you may not have to do anything, since the RefUnit already knows its Circuit.1. For valves with defrosts controlled by a Circuit node, open Circuit Defrost Details. Enter thedesired valve %Open for Pump Down, Active Defrost (47) and Drip.For Dual Temp cases using a CDS-9 EEPR valve, a 40%Open value is suggested for hot gas defrost through the valve. Opening the valve fully will take more time and not significantly increase the flow. 2. For valves with Internal Defrost, edit the schedule (48).Internal Defrosts are done off-time, by simply closing the EEPR valve. The schedule for Internal Defrosts is internal to the EEPR node and, in version 5.2 of Alliance, it is not yet integrated within the rack’s defrost schedule.7.1 Circuits Controlling more than One EEPR ValveWhen several EEPR valves are associated with a given Circuit for defrost, the DT-EEPR Plug-In automatically creates all the necessary bindings, so that defrost only starts after all the EEPR valves have been properly positioned. No intervention is required on the part of the user.45 474949488. Valve Control, Set Point– A warning (50) may appear in the Valve Control tab if the strategy seems inappropriate. This happens, for example, if the set point is within medium temperatures and the Strate-gy is set for frozen food.1. Click on the Details button (51) to open Strategy Detailsdialog box.The refrigeration Strategy determines how a RefUnit will be treated. Fresh meat, for example, will not load shed as readily as juice, and its temperature will be regulated more closely.2. Select the Strategy (52) that seems the most appropriate forthe type of merchandise.If you uncheck the Show All Strategies check box (53), you will see only those strategies which are compatible with the particular context of this RefUnit.3. Uncheck the Use from Primary RefUnit box (54) if youwish to set the temperature set point . Enter the desired value. For DualTemp RefUnits, two values are needed.If you leave this box (54) checked, the Optimal Value from the Alarm Set will be used as the set point. It will then be easier for the store personnel to modify it. It is assumed that the store per-sonnel have access to the RefUnits, but that they do not see the DT-EEPR plug-in. 4. Click Apply.– The DT-EEPR plug-in does all the bindings for you and sends the configuration to the node. – Temperature regulation begins.9. Historical DataYou may have been asked to select Historical Data. Even then, you need to do the following step. 1. Open the History page (55).2. Select all the data that you wish to log. Any unchecked network variable will not get logged, andyou will not be able to display it in Trendgraphs.50505154535255You may click on the Factory Default button to select automatically those network variables that are usually considered as the most important.10. Process Page1.Go to the Process tab and observe the following. – The names of the Primary RefUnits (56).– A thermometer indicating, for each valve, the Active Temperature Set Point (57), as well as the Instant (58) and Average (59) temperatures.– A banner (60) reveals any special valve status or activity (Defrost, Power Off, Override, etc). – Another banner (61) may show “Marginal” or the more severe “Conflict” warning. Conflict means that the valve is likely to run 100%Open all the time. Marginal means that the set point may be maintained, but not under extreme environmental conditions. In the case of Sys21 illus-trated above, a larger valve should have been used.– The actual %Open (62) of the valve is shown, with some visual indications (63) of its opening or closing (circles of decreasing or of increasing diameter.) A button is provided to force an Override (64).Note that the icon that represents a walk-in (room or open area) (65) is different from the icon rep-resenting a case.– Observe that the valves move as needed to maintain temperature, unless the circuit is undergo-ing a defrost. One move per minute is typical.After the valve has been in service for some time, a visual indication of the status of the control is displayed. A green circle means success. A red diamong (66) means that control could be improvedby tuning. A red square indicates that some intervention is probably needed.565758596061626364656610.1 Details of the Process1.Click on the buttons, at the bottom of the Process page, to access some additional information and trendgraphs. The bottom part of the Process page provides the following infor-mation :– the Active Set Point (67) (Set 1 or Set 2, for Dual Temp RefUnits only),– the EEPR control temperature, calculated from all the sensors involved, and referred to as “Instant Temperature” (68), – its running average (69), calculated over the last 15 minutes, – the accumulated Integral temperature error (70),– a button (71) that resets both the accumulated Integral and Long Term errors,– the location (72) of the Control Temperature Sensor in the Pri-mary RefUnit (normally Discharge Air for a case and Return Air for a room).The “Trend” button (73) opens a set of preselected trendgraphs for this RefUnit, and the “Less” button (74) hides the details.11. TrendgraphsThe underlined text contains hyperlinks to Trendgraph. If you click on Instant, for example, the Trendgraph for the (instant) EEPR Control Temperature opens. Prepackaged Trendgraphs are avail-able :1. Click on the “Trend” button to open the prepackaged Trendgraph for a RefUnit. –A new window opens, similar to the one below.7312. Environmental CorrectionsTo predict the valve %Open, the controller needs three environmental variables : the temperature and humidity around the case, and the temperature of the liquid refrigerant. These three environ-mental variables can affect the calculated flow of refrigerant by more than a factor of 2.The valve %Open is obtained from the calculated flow and pressure drop. PID corrections are then applied to obtain the final valve position. If the environmental corrections are not provided, the cal-culated value will be inaccurate, and the PID corrections will be used up to compensate. As a result, they won’t be available to compensate for other disturbances, and the site will become more vulner-able.With the DT-EEPR, setting up the Environmental Corrections takes only a minute. It is done as follows.1.The Space Temperature (75) is normally taken from the temperature sensor, inside the super-market, that is closest to the case or walk-in.2. For Space Humidity, any sensor inside the store, that provides Relative Humidity (76), can beused.3. Liquid Temperature is normally obtained from one of the nodes. nvoDlt (77) from the Con-denser node (Drop Leg Temperature) is a good candidate in some cases. If the rack is equipped with subcooling, the temperature of the liquid at the output of the subcooler is a better choice.– The indication of missing binding (78) disappears as its source is speci-fied.4. If, for some reason, you don’t have access to all three environmentalcorrections (liquid temperature not available, for example), provide those that you can. It will help.5. If an environmental correction becomes erratic (sensor malfunction, forexample) you can disable it by unchecking its box (79) in the Valve Ad-vanced Page. This can also be done to avoid getting the missing binding warning, if you were unable to provide the correction.7675777913. Valve Replacement andOther RepairsBecause the valve’s coils are induc-tive, unplugging a powered valve causes sparks that may disturb or, under extreme conditions, damage a controller.It is not necessary to power down the whole controller, in order to replace a valve. An individual drive can be powered off as follows. 1. Click on the Current Valuesbutton (80), to open the Cur-rent Values window. 2. Select the valve (81). 3. Click on Power Off.– The drive is powered Off. The valve will maintain its mechani-cal position until its drive is powered On again.– A Power On button replaces the Power Off button.– A Power Off banner appears in the Process page, reminding you that the drive is Off.– The Power Off condition also appears on top of the Valve Config page.13.1 What to do After a Repair1.Check that the valve is connected. If the drive is powered Off, you need to turn it back On, using the Power On (82) button in the Current Val-ues window.If the process has been running erratically for more than 30 minutes, it may be preferable to flush the accumulated errors. This is because the errors that were accumulated during the malfunction are not relevant to the present situ-ation. This is done as follows.2. Open the Process Page. If the More button appears, click on it to revealthe details. Then click on the Error Reset button (71)(83). – The Acc Errors value (84) goes to 0 after several seconds.8081828384Revisions HistoryCreation CB 08-Dec-060.1 Document0.1 Revision CC 31-Jan-07 0.2 More “Visual” version CB 09-Mar-07revision RL 20-Apr-070.3 Footer0.4 Logo and address changed RL 14-Dec-11。

All cables are individually serialized, be sure to write down the cable serial number for future reference.• Leave the protective sock around the fiber tails and power conductors during hoisting and securing the cable. • Be sure that the Direct breakout is not damaged by attachment of a hoisting grip or during the hoisting process. Attach a hoisting grip on the jacketed cable no less than .3 m (1 ft) below the fiber breakout point. Prevent the fiber tails and power conductors from undue movement during hoisting by securing the protective sock with tie ropes every 1 m (3 ft) to the hoisting line.• During hoisting ensure that there is a free path and that the cable, and especially the end of the pulling sock will not be snagged on tower members or other obstacles.• Installation temperature range is -22 F to +158 F (-30 C to +70 C).• Minimum cable bend radii can be found on-line in our eCatalog section at /andrew.• Maximum cable tensile load can be found on-line in our eCatalog section at /andrew.• CommScope Lace-Up Hoisting Grip 19256B-C required for FDH-series installations.• Hoisting Grip should be anchored to the support structure after the hangers are installed.• During final connections to RRU, do not bend the fiber ends tighter than 30 MM (1.2 IN) bend radius or you takethe risk of breaking the glass fibers.Hybrid Fiber Cables weigh more than traditional coaxial cables.

Perfect Core Alignment 2. Physical Contact3. Pristine Connector InterfaceToday’s connector design and production techniques have eliminated most of the challenges to achieving core alignment and physical contact. What remains challenging is maintaining a pristine end-face. As a result, CONTAMINATION is the #1 reason for troubleshooting optical networks.Implementing the process of cleaning and inspecting before mating can reduce the time spent troubleshooting, optimize signal performance and prevent damage.InspectingScan to view videoExcess Cable ManagementIf length of cable installed needs to be adjusted you can split the cable at the BBU end using the process below and then coiling the excess fiber subunits in a storage box.

Chapter 3Tax Planning Strategies and Related LimitationsSOLUTIONS MANUALProblems(32)[LO2, LO3 PLANNING] Isabel, a calendar-year taxpayer, uses the cash method ofaccounting for her sole proprietorship. In late December she received a $20,000 bill from her accountant for consulting services related to her small business. Isabel can pay the$20,000 bill anytime before January 30 of next year without penalty. Assume hermarginal tax rate is 40 percent this year and next year, and that she can earn an after-tax rate of return of 12 percent on her investments. When should she pay the $20,000 bill—this year or next?Option 1: Pay $20,000 bill in December:$20,000 tax deduction x 40 percent marginal tax rate = $8,000 in present value taxsavings.After-tax cost = Pretax Cost – Present Value Tax Savings= $20,000 – $8,000 = $12,000Option 2: Pay $20,000 bill in January:$20,000 tax deduction x 40 percent marginal tax rate = $8,000 in tax savings in oneyear.Present Value of Tax Savings = $8,000 x .893 (Discount Factor, 1 Year, 12 percent)= $7,144After-tax cost = Pretax Cost – Present Value Tax Savings= $20,000 – $7,144 = $12,856Paying the $20,000 in December is the clear winner.(33)[LO2, LO3 PLANNING] Using the facts from the previous problem, how would youranswer change if Isabel’s after-tax rate of return were 8 percent?Option 1: Pay $20,000 bill in December:$20,000 tax deduction x 40 percent marginal tax rate = $8,000 in present value taxsavings.After-tax cost = Pretax Cost – Present Value Tax Savings= $20,000 – $8,000 = $12,000Option 2: Pay $20,000 bill in January:$20,000 tax deduction x 40 percent marginal tax rate = $8,000 in tax savings in one year.Present Value of Tax Savings = $8,000 x .926 (Discount Factor, 1 Year, 8 percent)= $7,408After-tax cost = Pretax Cost – Present Value Tax Savings= $20,000 – $7,408 = $12,592Paying the $20,000 in December is the clear winner.(34)[LO2,LO3 PLANNING] Manny, a calendar-year taxpayer, uses the cash method ofaccounting for his sole proprietorship. In late December he performed $20,000 of legal services for a client. Manny typically requires his clients to pay his bills immediately upon receipt. Assume Manny’s marginal tax rate is 40 percent this year and next year, and that he can earn an after-tax rate of return of 12 percent on his investments. Should Manny send his client the bill in December or January?Option 1: Send $20,000 bill in December:$20,000 taxable income x 40 percent marginal tax rate = $8,000 in present value tax After-tax income = Pretax income – Present Value Tax= $20,000 – $8,000 = $12,000Option 2: Send $20,000 bill in January:$20,000 taxable income x 40 percent marginal tax rate = $8,000 in tax in one year.Present Value of Tax = $8,000 x .893 (Discount Factor, 1 Year, 12 percent)= $7,144After-tax income = Pretax income – Present Value Tax= $20,000 – $7,144 = $12,856Sending the $20,000 bill in January is the clear winner.(35)[LO2,LO3 PLANNING] Using the facts from the previous problem, how would youranswer change if Manny’s after-tax rate of return were 8 percent?Option 1: Send $20,000 bill in December:$20,000 taxable income x 40 percent marginal tax rate = $8,000 in present value tax After-tax income = Pretax income – Present Value Tax= $20,000 – $8,000 = $12,000Option 2: Send $20,000 bill in January:$20,000 taxable income x 40 percent marginal tax rate = $8,000 in tax in one year.Present Value of Tax = $8,000 x .926 (Discount Factor, 1 Year, 8 percent)= $7,408After-tax income = Pretax income – Present Value Tax= $20,000 – $7,408 = $12,592Sending the $20,000 bill in January is the clear winner.(36)[LO2, LO3 PLANNING] Reese, a calendar-year taxpayer, uses the cash method ofaccounting for her sole proprietorship. In late December she received a $20,000 bill from her accountant for consulting services related to her small business. Reese can pay the $20,000 bill any time before January 30 of next yea r without penalty. Assume Reese’s marginal tax rate is 30 percent this year and will be 40 percent next year, and that she can earn an after-tax rate of return of 12 percent on her investments. When should she pay the $20,000 bill—this year or next?Option 1: Pay $20,000 bill in December:$20,000 tax deduction x 30 percent marginal tax rate = $6,000 in present value tax savings.After-tax cost = Pretax Cost – Present Value Tax Savings= $20,000 – $6,000 = $14,000Option 2: Pay $20,000 bill in January:$20,000 tax deduction x 40 percent marginal tax rate = $8,000 in tax savings in one year.Present Value of Tax Savings = $8,000 x .893 (Discount Factor, 1 Year, 12 percent)= $7,144After-tax cost = Pretax Cost – Present Value Tax Savings= $20,000 – $7,144 = $12,856Paying the $20,000 in January is the clear winner.(38)[LO2, LO3 PLANNING] Hank, a calendar-year taxpayer, uses the cash method ofaccounting for his sole proprietorship. In late December he performed $20,000 of legal services for a client. Hank typically requires his clients to pay his bills immediately upon receipt. Assume his marginal tax rate is 30 percent this year and will be 40 percent next year, and that he can earn an after-tax rate of return of 12 percent on his investments.Should Hank send his client the bill in December or January?Option 1: Send the $20,000 bill in December:$20,000 taxable income x 30 percent marginal tax rate = $6,000 in present value tax After-tax income = Pretax income – Present Value Tax= $20,000 – $6,000 = $14,000Option 2: Send the $20,000 bill in January:$20,000 taxable income x 40 percent marginal tax rate = $8,000 in tax in oneyear.Present Value of Tax = $8,000 x .893 (Discount Factor, 1 Year, 12 percent)= $7,144After-tax income = Pretax income – Present Value Tax= $20,000 – $7,144 = $12,856Sending the $20,000 bill in December is the clear winner.(44)[LO3 PLANNING] Bob’s Lottery, Inc., has decided to offer winners a choice of$100,000 in ten years or some amount currently. Assume that Bob’s Lottery, Inc., earnsa 10 percent after-tax rate of return. What amount should Bob offer lottery winnerscurrently, in order for him to be indifferent between the two choices?$100,000 in ten years is worth $38,600 today to Bob ($100,000 x .386 (DiscountFactor, 10 Year, 10 percent)). Thus, Bob should offer lottery winners $38,600 today for him to be indifferent between the two choices.(45) [LO4 PLANNING] Tawana owns and operates a sole proprietorship and has a 40percent marginal tax rate. She provides her son, Jonathon, $8,000 a year for collegeexpenses. Jonathon works as a pizza delivery person every fall and has a marginal tax rate of 15 percent. What could Tawana do to reduce her family tax burden? How much pretax income does it currently take Tawana to generate the $8,000 after-taxes given to Jonathon? If Jonathon worked for his mother’s sole proprietorship, what salary would she have to pay him to generate $8,000 after taxes (ignoring any Social Security,Medicare, or self-employment tax issues)? How much money would this strategy save?Tawana could reduce her family’s tax burden by employing her son in her soleproprietorship, thus shifting income taxed at 40 percent (Tawana’s mar ginal tax rate) to 15 percent (Jonathon’s tax rate). It currently takes Tawana $13,333 ofpretax income to generate the $8,000 after-taxes given to Jonathon.After-tax income = Pretax income x (1 – marginal tax rate)$8,000 = Pretax income x (1 – .40)Pretax income = $8,000 / (.60) = $13,333.If Jonathon worked for Tawana’s sole proprietorship, she would only have to pay him $9,412 to generate $8,000 after-taxes.After-tax income = Pretax income x (1 – marginal tax rate)$8,000 = Pretax income x (1 – .15)Pretax income = $8,000 / (.85) = $9,412.This strategy will save Tawana $3,921 pretax (i.e., $13,333 – $9,412) and $2,353 after tax ($3,921 x (1 – .40)).(46)[LO4 PLANNING] Moana is a single taxpayer who operates a sole proprietorship. Sheexpects her taxable income next year to be $250,000, of which $200,000 is attributed to her sole proprietorship. Moana is contemplating incorporating her sole proprietorship.Using the single individual tax brackets and the corporate tax brackets, find out howmuch current tax this strategy could save Moana (ignore any Social Security, Medicare, or self-employment tax issues). How much income should be left in the corporation?Assuming Moana’s goal is to minimize her current federal income tax exposure, one can compare the single individual and corporate tax rate schedules to achieve this goal. Since Moana has $50,000 of taxable income not related to her soleproprietorship, she is currently in the 25 percent tax bracket. The task is to allocate the $200,000 between Moana and her corporation to minimize her current liability.The lowest corporate tax rate is 15 percent (taxable income from 0 to $50,000) and is lower than Moana’s marginal tax rate of 25 percent. To take advantage of the 15percent corporate tax bracket, $50,000 of the expected $200,000 in profits should be retained in the corporation. [$50,000 is the width of the 15 percent corporate tax bracket.] Assuming the corporation retains $50,000 of profit, the corporation’s marginal tax rate would now be 25 percent and thus, Moana’s choice is to haveincome taxed at 25 percent (the corporation’s marginal tax rate) or 25 percent(Moana’s marginal tax rate). Let’s assume that, all things equal, Moana prefers to receive the profits personally. To take ad vantage of Moana’s 25 percent personal tax bracket, the next $33,600 of the expected $200,000 in profits should be shifted to Moana. [$33,600 is the remaining width of Moana’s 25 percent tax bracket].Moana’s marginal tax rate would now be 28 percent. C ontinuing this same decision process, $25,000 of the remaining $116,400 of profits should be retained by thecorporation, and the rest ($91,400) should be shifted to Moana. In summary,$75,000 of the expected profits are retained in the corporation and $125,000 of the profits are shifted to Moana.This strategy will save Moana $11,000 calculated as:(a) The tax on $250,000 of taxable income reportedby Moana assuming that she operates her businessas a sole proprietorship. $67,397Less:(b) The tax on $175,000 of taxable income reportedby Moana assuming that she incorporates her business – $42,647and (c) the tax on $75,000 profits retained in the corporation – $13,750= $11,000(47)[LO4 PLANNING] Orie and Jane, husband and wife, operate a sole proprietorship.They expect their taxable income next year to be $275,000, of which $125,000 isattributed to the sole proprietorship. Orie and Jane are contemplating incorporating their sole proprietorship. Using the married-joint tax brackets and the corporate tax brackets, find out how much current tax this strategy could save Orie and Jane. How much income should be left in the corporation?Assuming Orie and Jane’s goal is to minimize their current federal income taxexposure, one can compare the married filing joint and corporate tax rate schedules to achieve this goal. Since Orie and Jane have $150,000 of taxable income notrelated to their sole proprietorship, they are currently in the 28 percent tax bracket.The task is to allocate the $125,000 between Orie and Jane and their corporation to minimize their current liability. The lowest corporate tax rate is 15 percent (taxable income from 0 to $50,000) and is lower than Orie and Jane’s marginal tax rate of 28 percent. To take advantage of the 15 percent corporate tax bracket, $50,000 of the expected $125,000 in profits should be retained in the corporation. [$50,000 is the width of the 15 percent corporate tax bracket.] Assuming the corporation retains$50,000 of pr ofit, the corporation’s marginal tax rate would now be 25 percent and thus, Orie and Jane’s choice is to have income taxed at 25 percent (the corporation’s marginal tax rate) or 28 percent (Orie and Jane’s marginal tax rate). 25 percent is the obvious cho ice. To take advantage of the corporation’s 25 percent tax bracket, the next $25,000 of the expected $125,000 in profits should be retained in thecorporation. [$25,000 is the width of the 25 percent corporate tax bracket]. The corporation’s marginal ta x rate would now be 34 percent. Continuing this samedecision process, the remaining $50,000 of profits should be shifted to Orie and Jane.In summary, $75,000 of the expected profits are retained in the corporation and$50,000 of the profits are shifted to Orie and Jane.This strategy will save Orie and Jane $10,385 calculated as:(a) The tax on $275,000 of taxable income reportedby Orie and Jane assuming that they operate their businessas a sole proprietorship. $68,204.50Less:(b) The tax on $200,000 of taxable income reportedby Orie and Jane assuming that they incorporate the business – $44,069.50and (c) the tax on $75,000 profits retained in the corporation – $13,750.00= $10,385.00(48)[LO4 PLANNING] Hyundai is considering opening a plant in two neighboring states.One state has a corporate tax rate of 10 percent. If operated in this state, the plant isexpected to generate $1,000,000 pretax profit. The other state has a corporate tax rate of2 percent. If operated in this state, the plant is expected to generate $930,000 of pretaxprofit. Which state should Hyundai choose? Why do you think the plant in the state witha lower tax rate would produce a lower before-tax income?Hyundai should choose to operate the plant in the state with the 2 percent tax rate.Operating the plant in this state would generate $911,400 of profits after state taxes(i.e., $930,000 – (2 percent x $930,000) = $911,400)) versus $900,000 of profits afterstate taxes (i.e., $1,000,000 – (10 percent x $1,000,000) = $900,000) in the state with the 10 percent tax rate.The state with a lower tax rate produces a lower pretax income because the demand for workers, services, property, etc. in the low-tax rate state jurisdictions has most likely increased the costs associated with operating a business in this state. These increased costs are considered implicit taxes and reduce the tax advantages ofoperating in the low tax rate state.(51)[LO5 PLANNING] Dennis is currently considering investing in municipal bonds thatearn 6 percent interest, or in taxable bonds issued by the Coca-Cola Company that pay 8percent. If Dennis’ tax rate is 20 percent, which bond should he choose? Which bond should he choose if his tax rate is 30 percent? At what tax rate would he be indifferent between the bonds? What strategy is this decision based upon?Dennis’ after-tax rate of return on the tax exempt bond is 6 percent (i.e., the same as its pretax rate of return). The Coca-Cola Company bond pays taxable interest of 8 percent. Dennis’ after-tax rate of return on the Coca-Cola Company bond is 6.4 percent (i.e., 8 percent interest income – (8 percent x 20 percent) tax = 6.4 percent). Dennis should invest in the Coca-Cola Company bond.If Dennis’ marginal tax rate is 30 percent, his after-tax rate of return on the Coca-Cola Company bond would be 5.6 percent (i.e., 8 percent interest income – (8 percent x 30 percent) tax = 5.6 percent). Dennis should invest in the tax exempt bond in this situation.Dennis would be indifferent between the two bonds if his marginal tax rate is 25 percent.After-tax return = Pretax return x (1 – marginal tax rate)6 percent = 8 percent x (1 – marginal tax rate) = 8 percent – (8 percent x marginal tax rate)8 percent marginal tax rate = 2 percentmarginal tax rate = 2 percent / 8 percent = 25 percentThis example is an illustration of the conversion planning strategy.。
