Buying a Car at Auctions


Recently one of my friends bought a car in an auction. What is the thing to consider is the price he paid for it. Unbelievably he got the car at nearly 45 per cent discount price which is a really dead cheap for what he got. But when he made a check on the car with a mechanic, he found some considerable repairs to be made for a smooth ride.

Though that didn’t cost much for his pocket, there is nothing like saving when he calculated the price of the car and the repairs done to it. But at the end my friend left with a good experience in buying a used car that too at the public auctions. Here are the two important benefits of buying a car at the auctions according to him.

At auctions the bid starts at a dead cheap price, some times at 70 to 90 per cent discount. You will be lucky if you got the deal at that price. The closure of the bid may end at a higher note depending on the participants in the auction and on the car like the make, model, history and usage etc.

One more thing is you can get a rare model at the auctions and in some cases the imported ones. If you have a make and model in mind, check online auctions for that, you have a better chance to find it there.

Mentorship In The Organizations

Mentorship refers to a developmental relationship between a more experienced mentor and a less experienced partner referred to as a mentee or protege -- a person guided and protected by a more prominent person.

There are two types of mentoring relationships: formal and informal. Informal relationships develop on their own between partners. Formal mentoring, on the other hand, refers to assigned relationships, often associated with organizational mentoring programs designed to promote employee development. In well-designed formal mentoring programs, there are program goals, schedules, training (for mentors and mentees), and evaluation. Mentors inspire their mentee to follow their dreams. There are many kinds of mentoring relationships—from school- or community-based relationships to e-mentoring relationships.

In 1990, Mentor created The Elements of Effective Practice, a crucial tool for state and local mentoring organizations matching mentors and youth mentees in formal, high-quality mentoring relationships of all kinds. Revised and updated several years later with a companion toolkit, The Elements guidebook reflects the latest in quality mentoring research, policies, and practices.

For example, in some programs, newcomers to the organization (protégés) are paired with more experienced people (mentors) in order to obtain information, good examples, and advice as they advance. It is considered that new employees who are paired with a mentor are twice as likely to remain in their job as those who do not get mentorship.

In other cases, mentoring is used to groom up-and-coming employees deemed to have the potential to move up into leadership roles. Here the employee (protégé) is paired with a senior level leader (or leaders) for a series of career-coaching interactions. A similar method of high-potential mentoring is to place the employee in a series of jobs in disparate areas of an organization, all for small periods of time, in anticipation of learning the organization's structure, culture, and methods. A mentor does not have to be a manager or supervisor to facilitate the process.

Two other large holding companies of note are UAL Corporation and AMR Corporation, publicly traded holding companies whose primary purposes are to wholly own United Airlines and American Airlines, respectively.

Sometimes a company intended to be a pure holding company identifies itself as such by adding "Holdings" or "(Holdings)" to its name.

A parent company is a holding company that owns enough voting stock in another firm (subsidiary) to control management and operations by influencing or electing its board of directors. A parent company could simply be a company that wholly owns another company.

In the United States of America, a personal holding company is defined in section 542 of the Internal Revenue Code. A corporation is a personal holding company if both of the following requirements are met:
  • Personal Holding Company Income Test: At least 60% of the corporation's adjusted ordinary gross income for the tax year is from dividends, interest, rent, and royalties.
  • Stock Ownership Requirement: At any time during the last half of the tax year, more than 50% in value of the corporation's outstanding stock is owned, directly or indirectly, by 5 or fewer individuals.

Types Of Corporations

C-Corporation
  • The C-Corporation which is a regular (or standard) corporation.
  • A disadvantage of a C-Corporation is that it has to pay corporate taxes on corporate profits and when it distributes profits to its stockholders, the stockholders have to pay income tax on those dividends. The formation of a LLC or an S-Corporation will eliminate double taxation.
S-Corporation
  • An S-Corporation is granted a special tax status under the Internal Revenue Code (IRC). The ‘S’ stands for small business corporation.
  • An S-Corporation has limited liability of a Corporation but taxes are pass through to the individual shareholders based on their proportional share ownership. That means, shareholders will be taxed based on how much shares they own in the company and not how much payout they have received.
  • An S-Corporation has a limit on the number of shareholders who must be US residents.
  • To qualify as an S-Corporation, your Corporation must be filed at the state level and the Corporation must not have more than 75 shareholders. All the shareholders must be a U.S. citizen or a Permanent Resident Alien with a Green Card. The Corporation can only have one class of stock.
Professional Corporation
  • A professional corporation is a type of corporation which provides a service that requires a license.
  • Licensed practitioners like engineers, lawyers, chiropractors, accountants, architects or doctors are required to form professional corporations.
Limited Liability Company (LLC)
  • A LLC is an in-between of a corporation and a partnership.
  • A LLC member can be an individual or a separate entity (e.g. a corporation or a partnership) that has a share in the LLC.
  • As similar to a corporation, a LLC protects its members from personal liability for business debts and court rulings against the LLC. Only the money invested into the corporation will be at risk.
  • As similar to a partnership, a LLC is formed by the filing of a certificate of formation with the Secretary of State and will be taxed like a partnership.
  • Like a partnership, the members of LLCs have to create an operating agreement to state how the LLC business will be managed.
  • A LLC does not restrict its owners to be US residents.
  • A LLC can have more flexibility in its management style because it is controlled by the members and not by the state’s Business Corporation Act.
  • A LLC is taxed as a partnership (where any income and deductions of the LLC is passed through to the members as their personal returns) unless it has been elected as a corporation.
Non-Profit
  • A non-profit corporation is granted tax-exempt status under the IRC.
  • Such a corporation need not pay any taxes on its income. Any person or organization who donates to a non-profit corporation can get a tax deduction for the contribution made.

Types Of Health Insurances

Health insurance protects you and your family from a financial hardship due to medical expenses in the untimely event that you are injured or become ill. There are four types of health insurance, you may need just one or you may need a combination to ensure you have the most insurance coverage possible. It is best to evaluate each type of insurance to obtain an accurate account of which type will best suit your needs.

Individual medical coverage is designed for people who do not receive this type of coverage through their employer or family. Medical supplement insurance is designed for the elderly who contribute to Medicare however, desire additional coverage to supplement expenses that Medicare won’t cover. Hospital income insurance is intended to compliment your main health insurance program. This coverage provides a prearranged daily benefit amount for unforeseen expenditures that accompany extended hospital stays for a covered sickness or injury. The fourth type of health insurance coverage is disability insurance, which comes in three different forms. Disability insurance protects you in the event you become physically or mentally disabled due to an accident or illness. This type of insurance is designed to provide you with your living expenses if a disability prevents you from working or earning a living.
