1.
Building a balance sheets
   Current assets         $4,900
   Net fixed assets       $27,300
   Current liabilities             $4,100
   Long-term debt         $10,200
   Shareholders equity             (4,900 + 27,300) – ( 4,100 + 10,200) = 17,900
                                   (total assets – total liabilities)
   Net working capital             4,900 – 4,100 = 800
                                   (current assets – current liabilities)
2. Bulding an income statement
   Revenue                         $796,000
   Costs of goods sold             $327,000
   Gross income           769,000 – 327,000 = 442,000
   Depreciation expense            $42,000
   Interest expense                $34,000
   Total expense          42,000 + 34,000 = 76,000
   Earning before tax              442,000 – 76,000 = 366,000
   Taxes                           21% x 366,000 = 76,860
   Net income                      366,000 – 76,860 = 289,140
3. Dividends and Retained Earnings
   Dividends                       $95,000
   Retained earnings               289,140 – 95,000 = 194,140
                                   (net income – dividends)
4. Per-share Earnings and Dividends
   Earnings Per-share              289,140 / 80,000 = 3.61435
   Dividends Per-share             95,000 / 80,000 = 1.1875
5. Calculating Operating cash flow
   Revenue                         $46,200
   COGS                            $23,000
   Gross income            $23,200
   Depreciation expense            $2,200
   EBIT                            $21,000
   Interest expense                $1,700
   EBT                             $19,300
   taxes                           $4,246
   Net income                      $15,054
   OCF                             23,200 – 4,246 = 18,954
                                   (EBIT + Depreciation – Taxes)
6. Calculating Net capital spending
   Net fixed assets 2017           $2,4m
   Net fixed assets 2018           $3,3m
   Depreciation                    $319,000
   Net capital spending            2,4m + 3,3m – 319,100 = 2,410,900
                           (ending net fixed + begining net fixed – depreciation)
7. Calculating additions to NWC (net working capital)
                           2017 balance sheet
   Current assets                  $4,810
   Current liabilities             $2,230
   NWC                             $2,580 (current assets – current liabilities)
                           2018 balance sheet
   Current assets                  $5,360
   Current liabilities             $2,970
   NWC                             $2,390
   Change in NWC                   $2,390 – $2,390 = – 190
8. Cash flow to creditor
   Long-term debt in 2017 $1,870,000
   Long-term debt in 2018 $2,210,000
   Net new borrowing             2,210,000 – 1,870,000 = 340,000
                                 (kỳ này – kỳ trước)
   Interest expense in 2018      $255,000
   Cash flow to creditors 255,000 – 340,000 = – 85,000
9. Future value: General formula
   FVt = PV(1 + r)t
   -   FVt = future value
   -   PV = present value
   -   r = discount rate
   -   t = number of periods
   PV = FVt / (1 + r)t
10. Annuities
               ( 1+ r )t −1
   FVAt = CF
                    r
Chapter 5
Ex.1:
r = 9%, t = 8, PV = 7,500
FVt = 7,500*(1 + 9%)^8 = 14,944
Ex.2:
FVt = 2,328*(1 + 13%)^11 = 8,929
FVt = 7,513*(1 + 9%)^7 = 13,734
FVt = 74,381*(1 + 12%)^14 = 363,508
FVt = 192,050*(1 + 6%)^16 = 487,874
Ex. 3:
PV = 16,832/(1 + 9%)^13 = 5,490
PV = 48,318/(1 + 7%)^4 = 36,861
PV = 886,073/(1 + 13%)^29 = 25,597
PV = 550,164/(1 + 21%)^40 = 268
Chapter 6:
Ex.1: tính PV của từng CF => tính PV tổng
r = 10%,
