決策超過 5 小時？小心專案成功率只剩 18％

能夠在一小時以內迅速做出決策的專案，成功率高達58％（而且是在預算之內準時完成）。但要是決策耗時超過五個小時，成功率就會大幅下降到只剩18％

US economy forecast at end Mar 2020

Dear Bobby ~ 

Recently I subsequently explore on US market, also talk with a few investors who are both good at US economy observations. There are some points summarised as follow :

1. Last time we mentioned IHS Markit US Services Feb PMI sharply down 4% with the forecast. But leading index for manufactured sector Chicago PMI of Jan-Feb-Mar show as 42-49- 47.8. Unfinished orders soar and business inventory have been in minus since last Nov. It seems that business inventory is on closeout ( or clearance). and if US consumption can keep going, It'll create persistent demand for industrial production. Another sign to back up view is that  Capacity Utilization in Manufacturer increased to 77 percent in February from 76.60 percent in January

有關 Alteryx 的 Stock options 員工認股一點思考

看過Alteryx 公司的stock option, 有發現一些新的東西
stock option 是否會對於公司股價造成影響, 很難下定論, 影響成因也複雜
簡單來說請先看這張現金流量表的operating activity added back items, 截至2019Q3 公司在Stock based compensation 項目認列22,195費用( 千元單位) 只要員工有參加stock option股權獎勵計畫, 會計帳會認列一筆費用在Stock based compensation 項目下, 至於數字認列多少稍後再談, 那麼這筆22,195並沒有真正牽涉現金進出, 所以現金流量表會把它加回來

  WeWork’s Debt Capacity



In the wake of the pulled IPO of The We Company (f/k/a as WeWork Companies, Inc.) the company’s ability to incur debt is of interest. In its S-1/A for the IPO, WeWork contemplated a new bank facility, to be entered into concurrently with the equity offering. That facility would have provided $2B of letters of credit and $4B of delayed draw term loans; however, only $1B of those loans would have been available “prior to receipt of financial statements for the three months ended June 30, 2020.”
With the IPO now out of the picture, WeWork is in need of cash—both debt and equity—with Bloomberg yesterday reporting that two paths are contemplate $5B of debt or an equity investment by SoftBank pursuant to which it would control the company. In addition, in its S- 1/A, WeWork disclosed that under its existing (private) credit facility that as of the end of Q2 , while it was in compliance with its covenants under the credit agreement and LC arrangements, it would not have been able to borrow in the future under its credit agreement due to financial covenants.
WeWork has outstanding $669mm of 7.875% Senior Notes due 2025, issued in April 2018. Other than the 30% equity claw (70% must remain outstanding), these bonds are only callable at their make-whole until 3 months prior to maturity—at approximately 129. In this report we take a look at debt capacity under the Senior Notes.
