The comparative statements of financial position for 2023 and 2022 are given below for Surmise Company. Net profit for 2023 was $50 million.

Required:
Prepare the statement of cash flows of Surmise Company for the year ended December 31, 2023, assuming Surmise classifies interest paid, interest received, and dividends received as operating activities and dividends paid as a financing activity. Use the indirect method to present cash flows from operating activities because you do not have sufficient information to use the direct method. You will need to make reasonable assumptions concerning the reasons for changes in some account balances. A spreadsheet or T-account analysis will be helpful. (Hint: The right to use a building was acquired with a seven-year lease agreement. Annual lease payments of $9 million are paid on January 1 of each year starting in 2023.) (Enter your answers in millions (i.e., 10,000,000 should be entered as 10.). Amounts to be deducted should be indicated with a minus sign.)

A paint booth operation runs 5 days per week. As the production supervisor, you track the number of errors produced by the paint booth by week. Errors can be of any type (over spray, inadequate coverage, etc.), may occur on one or more pieces of equipment, and the number and type of equipment painted varies greatly. Ten weeks of data were collected and the number of errors identified are found in the following table. Construct a control chart with 3-sigma control limits to determine if the process is in control. Week Number of errors 1 5 2 4 3 5 4 4 5 4 6 3 7 0 8 2 9 0 10 3 1. What are the CL, UCL, and LCL? 2. Draw the control chart and plot the 10-weeks of data? 3. Does the control chart suggest that the paint booth operation may be out-of-control? Explain. 4. After investigating, you determine that there is a special cause. The paint booth had become wore and was overhauled after Week 5. What, if anything, should you do to continue monitoring the paint booth operation? Please demonstrate what should be done.

Take 5 cards from a 52 card deck without replacement.

a) Use the multiplication principle reason out the number of ways to get 1 pair

and 3 other non-paired cards

               (Hint: Fill in the number of ways to choose: 1 card type, 1 matching card,

1 card that doesn’t match, 1 card that doesn’t match any of the previous 3, 1 card that doesn’t match any of the previous.

b) How many ways can you draw out a set of 5 cards?

               c) What’s the probability of exactly one pair?

               d) How many times would you expect to exactly one pair in 50 trials?

               e) Run 50 trails (shuffle each time if you’re using a real deck of cards)

                              How many times did you get exactly one pair?

                              Is this consistent with what’d you expect from part (d)?

A property has first year NOI of $1.5 million. NOI grows at 7% during the next two years. In year four, NOI goes drops 50% due to a lost tenant. You are very lucky and replace the tenant. Year five NOI is 4X year four. (continues below…)

1. What is year 5 NOI?

continue…You have a $10 million mortgage on this property, at 5% interest, amortization of twenty years. There are two partners who have invested $3 million total in the property. Partner A is the operator and has invested 20%. Partner B, the finance partner has invested 80%.  The partners share the cash flow in the following manner:

8% minimum return, pro rata to the amount of investment. The finance partner has a preference. In return for giving the finance partner a preference, the operating partner is entitled to twice their pro rata share of any excess cashflow.

2. How much does partner A receive over the five years?
3. How much does partner B receive over the next five years?

Extra credit

Assume that the finance partner can clawback from the operating partner to meet the minimum return.

4. How much does Partner A receive?
5. How much does Partner B receive?
